Food, water, and worker protection regulations have driven availability, and loss, of pesticides for use in pest management programs. In response, public-supported research and extension projects have targeted investigation and demonstration of reduced-risk integrated pest management (IPM) techniques. But these new techniques often result in higher financial burden to the grower, which is counter to the IPM principle that economic competitiveness is critical to have IPM adopted. As authorized by the 2002 Farm Bill and administered by the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS), conservation programs exist for delivering public-supported financial incentives to growers to increase environmental stewardship on lands in production. NRCS conservation programs are described, and the case for providing financial incentives to growers for implementing IPM is presented. We also explored the opportunity and challenge to use one key program, the Environmental Quality Incentives Program (EQIP), to aid grower adoption of IPM. The EQIP fund distribution to growers from 1997 to 2002 during the last Farm Bill cycle totaled approximately 1.05 billion dollars with a portion of funds supporting an NRCS-designed pest management practice. The average percentage of allocation of EQIP funds to this pest management practice among states was 0.77 +/- 0.009% (mean +/- SD). Using Michigan as an example, vegetable and fruit grower recognition of the program's use to implement IPM was modest (25% of growers surveyed), and their recognition of its use in aiding implementation of IPM was improved after educational efforts (74%). Proposals designed to enhance program usefulness in implementing IPM were delivered through the NRCS advisory process in Michigan. Modifications for using the NRCS pest management practice to address resource concerns were adopted, incentive rates for pest management were adjusted, and an expanded incentive structure for IPM technique adoption was tabled for future consideration. The case is strong for using public-supported financial incentives offered by the EQIP to aid grower adoption of IPM as a means to address resource concerns, but current use of the EQIP for this purpose is modest to meager. With appropriate program adjustments and increased grower awareness, USDA NRCS conservation programs, and the EQIP in particular, may provide an important opportunity for growers to increase their use of IPM as a resource conservation and farm management tool.  相似文献

This study compared an integrated pest management (IPM) program with conventional, calendar-based pest control in nine North Carolina elementary schools. Both programs primarily targeted the German cockroach, Blattella germanica (L.). The IPM program relied heavily on monitoring and baiting, whereas the conventional approach used baseboard and crack-and-crevice sprays of insecticides. Within the constraints of an existing pest management contract, we quantified service duration, materials used, cost, levels of cockroach infestation, and the pesticide residues generated by the two service types. IPM services were significantly more time-consuming than conventional services, resulting in a significantly higher cost associated with labor. Nevertheless, the two types of treatments incurred similar total costs, and the efficacy of both treatments was also similar. Most importantly, pest monitoring, a central element of the IPM program, revealed few cockroaches and indicated that most of the conventional treatments were unnecessary. Environmental residues of the organophosphate pesticides acephate, chlorpyrifos, and propetamphos were significantly higher in swab samples taken in the conventionally treated schools. This study demonstrates that an IPM program is an appropriate and preferable alternative to conventional methods of pest control in the school environment.  相似文献

Role of imidacloprid in integrated pest management of California citrus   总被引:2,自引:0,他引:2  
Portions of three commercial citrus orchards were treated for 1 yr with foliar imidacloprid or for 2 yr with a systemic formulation in a replicated plot design to determine the impact of this neonicotinoid on the San Joaquin Valley California citrus integrated pest management (IPM) program. Foliar-applied imidacloprid had little effect on California red scale, Aonidiella aurantii (Maskell); cottony cushion scale, Icerya purchasi Maskell; or citrus red mite, Panonychus citri (McGregor), populations. Short-term suppression of the parasitoids Aphytis melinus DeBach and Comperiella bifasciata Howard; vedalia, Rodolia cardinalis (Mulsant); and the predacious mite Euseius tularensis (Congdon) were observed. Suppression of natural enemies allowed scales and mites to maintain higher populations in the treated areas compared with the nontreated areas. Thus, foliar imidacloprid did not exhibit control of these citrus pest species, and it disrupted biological control. Systemically applied imidacloprid suppressed California red scale and citricola scale populations 2-3 mo after treatment. Suppression of parasitoids of the California red scale also was observed. Thus, treatments of systemic imidacloprid applied in areawide management programs for invasive pests would provide a benefit of California red scale and citricola scale suppression. However, this treatment provided only single-season control of citricola scale, it was somewhat disruptive of biological control, and it did not suppress densities of either scale as low as a treatment of the organophosphate chlorpyrifos for citricola scale or the insect growth regulator pyriproxyfen for California red scale. Insecticides with longer periods of efficacy and greater IPM compatibility than imidacloprid should be used for a sustainable IPM approach in California citrus.  相似文献

Lepidoptera are among the most severe pests of food and fibre crops in the world and are mainly controlled using broad spectrum insecticides. This does not lead to environmentally sustainable control and farmers are demanding alternative control tools which are both effective and friendly to the environment. The sterile insect technique (SIT), within an area‐wide integrated pest management (AW‐IPM) approach, has proven to be a powerful control tactic for the creation of pest‐free areas or areas of low pest prevalence. Improving the quality of laboratory‐reared moths would increase the efficacy of released sterile moths applied in AW‐IPM programmes that integrate the (SIT). Factors that might affect the quality and field performance of released sterile moths are identified and characterized in this study. Some tools and methods to measure, predict and enhance moth quality are described such as tests for moth quality, female moth trapping systems, ‘smart’ traps, machine vision for recording behaviour, marking techniques, and release technologies. Methods of enhancing rearing systems are discussed with a view to selecting and preserving useful genetic traits that improve field performance.  相似文献

Abstract This paper deals with the relevance of biotechnology and IPM to small scale farmers in South and Southeast Asia. IPM may be defined as the combination and integration of approaches to pest management. which maximizes real profitability and genuine sustainability for the users and farming system and gives due regard to the environment. Alternative and practical pest management options should be developed for small scale farmers who could become experts in crop management and capable of making informed decisions through training in field schools. The latest development of biotechnology includes diagnostics, biological pesticides (either genetically manipulated or not genetically manipulated), transgenic plants and animals (vertebrates and invertebrates) and informatics. The place of biotechnology in rice IPM and vegetable IPM in South and Southeast Asia is discussed. Examples of soybean caterpillar in Brazil and rice blast in Vietnam illustrate the benefits of a strong working partnership between farmers, trainers and researchers in creating new knowledge which promotes sustainable agriculture.  相似文献

Integrated pest management (IPM) is an interdisciplinary science dealing with the development, evaluation, and implementation of pest control strategies that result in favorable economic, ecologic, and sociologic consequences. IPM has received considerable attention during the past few years, and this has led to recommendations directly related to the growth of the science of hematology. This report describes the current state of IPM in relation to the role of hematology, with special emphasis on scientific personnel requirements. All current indications are that IPM will continue to grow, very likely at an increased rate. This will place additional research, extension, and teaching demands on current hematology programs and should result in an expended resource base for nematology.  相似文献

The fall‐webworm (FWW), Hyphantria cunea, is a highly polyphagous insect pest that is native to North America and distributed in different countries around the world. To manage this insect pest, various control methods have been independently evaluated in the invaded areas. Some of the control methods have been limited to the laboratory and need further study to verify their effectiveness in the field. On the other hand, currently, integrated pest management (IPM) has become a promising ecofriendly insect pest management option to reduce the adverse effect of insecticides on the environment. The development of an IPM for an insect pest must combine different management options in a compatible and applicable manner. In the native areas of the insect pests, there are some recommended management options. However, to date, there is no IPM for the management of the FWW in the newly invaded areas. Therefore, to develop an IPM for this insect pest, compilation of effective management option information is the first step. Thus, believing in the contribution of an IPM to the established management strategies, the chemical, biological, natural enemy, sex pheromone, and molecular studies regarding this insect were reviewed and potential future research areas were delineated in this review study. Therefore, using the currently existing management options, IPM development for this insect pest should be the subject of future research in the newly invaded areas.  相似文献

Traditionally, rice farmers in Asia were thought to be unable to comprehend biological control because it was too esoteric. This perception was exacerbated by vested interest that prefers to maintain monopoly of information. Hence, between 1950 to 1990, the preferred method of extending technical information to farmers was to package them in “simplistic” messages. For example, prophylactic chemical control was a common approach of many extension systems in Asian economies during that period despite evidence from ecological studies to the contrary. In fact, the dogma that chemical control is equal to modern agriculture persists to this day in some countries. Such an approach often exaggerated yield loss figures to scare and justify use of chemical insecticides which eventually resulted in further yield losses. There has been increasing evidence that in tropical Asia, natural enemies are ubiquitous in rice fields and are responsible for keeping populations of rice herbivores in check. The rise of the brown planthopper as a serious pest was linked to regular use of insecticides. Outbreaks of this delphacid in tropical rice resulted from destruction of effective predators. With the help of biological control scientists, the FAO Intercountry Programme for Integrated Pest Control in South and Southeast Asia (ICP) presented evidence to the President of Indonesia in 1986 and secured a ban of 57 types of insecticides from rice fields. Promulgating legislative actions was a start and to sustain it an education programme to help farmers understand the importance of biological control was developed. This programme recognised that a traditional top-down process of instructing farmers would not help farmers and a non-formal education process of learning by experimenting and discovery was formulated. This approach emphasised the need for farmers to understand the rice ecosystem. Hence, rice fields became classrooms for farmers participating in the Farmer Field Schools. Farmers learned that not ail arthropods in the field are pests and to their surprise, most of the arthropods are “friendly“ insects. They discovered that these friendly insects eat herbivores. Using insecticide check and exclusion cage experiments, farmers learned of the adverse impact of insecticides and the impact of predators in keeping herbivore populations in check. The curriculum includes crop physiology, agronomy, health risks to insecticides and group dynamics. The principles of IPM emphasised in the Farmer Field Schools are: 1) Grow a healthy crop; 2) Visit fields regularly, preferably once a week to monitor field situation; 3) Understand and conserve natural enemies; 4) Farmers become experts in pest management. Adoption of this approach has led to a 60% drop in use of insecticides resulting in 13% increase in yield. Similar results were achieved in Vietnam and the Philippines. Facilitating farmers to understand biological control through field investigations is the key to successful implementation of Integrated Pest Management  相似文献

Pest management on a global scale experienced a total revolution after World War II when synthetic organic compounds were in agriculture and public health. However, it soon became apparent that there were many limitations in the use of chemicals for pest management. In agriculture, problems of pest resurgence, secondary pest outbreaks, pest resistance and adverse effects of pesticides on the environment, including human poisoning and toxicity to other non-target organisms, led to the search for alternative approaches to the pest outbreak problem. The 1960s produced new ideas on integrated pest management (IPM) strategies, followed by intensification of the search for biological control agents, which could be incorporated into IPM programmes. New application technologies were developed in the 1970s and 1980s and ecological approaches to the pest problem were spearheaded in the developed world in the 1990s, with extensive studies focused on the whole ecosystem. Important advances in crop production have also taken place in Africa in this century, involving adoption of high yielding varieties, fertilizer application, intensification of crop protection approaches, less shifting cultivation and more mono-cropping systems. However, these advances have led to increasing pest problems which unless tackled imaginatively and intelligently, they could become the most important constraint in crop production in the present millennium. Africa has entered the current millennium with relatively underdeveloped agriculture on a global scale and little investment in research on new pest management technologies that could be used to reduce crop losses. We are still highly dependent on pesticides for pest management. Therefore, the greatest challenges in agriculture in Africa will be the switch from a pesticide based mode of reducing losses due to pests to one that is ecosystem based, making use of insect management techniques which are ecologically and economically sound. Specifically, some of the major challenges in pest management in agriculture in Africa include; (i) reducing the dependence on pesticides, thus avoiding the limitations observed in the past 50 years; (ii) overcoming ignorance of the pest species and their associated community of parasites and predators which has dire consequences on the whole ecosystem; (iii) keeping out exotic pests, which in this millennium have had a devastating blow on the production of some crops and (iv) developing indigenous technologies for pest management (IPM, biocontrol, etc.) and making available to farmers materials for pest management which are affordable, safe, effective and environmentally friendly (e.g. microbial, botanicals, pheromones, genetically engineered products etc.). Both legislative and quarantine measures will have a significant role to play in pest management in the next millennium, but only when practised on a wider geographical area. Information technology (IT) will affect the way we acquire and make use of pest management strategies. Africa is therefore faced with the challenge of building up and improving its infrastructure and expertise on IT if it is to benefit pest management on the continent.  相似文献

The integrated pest management (IPM) of soybean developed and implemented in Brazil was one of the most successful programs of pest management in the world. Established during the 1970s, it showed a tremendous level of adoption by growers, decreasing the amount of insecticide use by over 50%. It included outstanding approaches of field scouting and decision making, considering the economic injury levels (EILs) for the major pests. Two main biological control programs were highly important to support the soybean IPM program in Brazil, i.e., the use of a NPVAg to control the major defoliator, the velvet bean caterpillar, Anticarsia gemmatalis Hübner, and the use of egg parasitoids against the seed-sucking stink bugs, in particular, the southern green stink bug, Nezara viridula (L.). These two biological control programs plus pests scouting, and the use of more selective insecticides considering the EILs supported the IPM program through the 1980s and 1990s. With the change in the landscape, with the adoption of the no-tillage cultivation system and the introduction of more intense multiple cropping, and with the lower input to divulge and adapt the IPM program to this new reality, the program started to decline during the years 2000s. Nowadays, soybean IPM is almost a forgotten control technology. In this mini-review article, suggestions are made to possibly revive and adapt the soybean IPM to contemporary time.  相似文献

When used alone, only a minority of biological control programs succeed in bringing the target pest population under sufficient control. Biological control is, therefore, usually employed with chemical, cultural, genetic or other methods in an integrated pest management (IPM) strategy. The interactions between different pest management methods, especially conventional pesticides and host plant resistance, is an area of growing research interest but relatively little consideration is given to novel combinations. This paper reviews the interactions between biological control and other forms of pest management, especially induced plant defences and the novel, non-toxic plant protection compounds that may boost these defences; and sterile insect technique. We also cover the cultural methods that offer scope to support synergies between the aforementioned methodological combinations. We conclude that despite the sometimes negative consequences of other pest management techniques for biological control efficacy, there is great scope for new strategies to be developed that exploit synergies between biological control and various other techniques. Ultimately, however, we propose that future use of biological control will involve integration at a greater conceptual scale such that this important form of pest management is promoted as one of a suite of ecosystem services that can be engineered into farming systems and wider landscapes.  相似文献

This study assessed the cost and effectiveness of an integrated pest management (IPM) program using hydramethylnon gel baits compared with conventional spraying for controlling the German cockroach, Blattella germanica (L.) (Blattodea: Blattellidae), in two residential buildings in Yasuj, Iran. The IPM approach was based on educational programs using pamphlets, posters and lectures, sanitation using vacuuming and application of hydramethylnon gel baits. Conventional approach used cypermethrin (10% EC) on baseboard and cracks-and-crevices. Sticky traps were used as tools for monitoring cockroach population densities. The IPM approach reduced (943%) the rate of insecticide application compared to the conventional spray. Cockroach populations in the IPM treatment were significantly reduced from an average of 12.2 ± 3.01 cockroaches per unit before treatment to zero cockroach per unit by week four and thereafter. Cockroach populations in the conventional spray treatment were reduced from an average of 11.5 ± 4.43 cockroaches per unit before treatment to an average of 3.4 ± 0.99 cockroach per unit after 11 weeks of post treatment. The IPM treatment improved 100% of infested units compared to 78% for spray treatment to obtain a clean level of infestation (< 1cockroach per trap per unit). The results suggest that the intervention by IPM using hydramethylnon gel baits significantly reduced cockroach infestation compared to cypermethrin spray throughout the 11 weeks of post-treatment period. However, within the study period, the IPM system involving gel baits, educational program and sanitation was 363.2% more expensive than the conventional method.  相似文献
