近10年来,盲蝽在我国由次要害虫上升为了主要害虫,在棉花、枣、葡萄等多种作物生产上造成了严重危害。自2008年以来,在公益性行业(农业)科研专项经费项目的支持下,对盲蝽人工饲养技术、个体发育与繁殖、食性、寄主选择行为、取食行为、性信息素通讯行为、交配与产卵行为、飞行与扩散能力、滞育与越冬习性、年生活史等生物学特性进行了系统研究,为研发盲蝽预测预报和综合防治技术提供了必要的科学依据。  相似文献

Starch attracts public attention as a replacement of fossil fuel in polymer industries because it is renewable, biodegradable and nontoxic. In this study, the isolation of starch from defatted cashew nut shell (CNS) using wet milling was reported. A product that contains 85.01 wt.% starch was recovered from the defatted CNS. Various analyses were performed on the starch to characterize its physicochemical properties. It was found that the starch obtained possesses high amylopectin content (75.35 wt.%), which supports the results of thermal analysis that proved the high crystallinity of starch. Morphological study of the starch showed that bonded resins were found attached to the starch granules. Due to high crystallinity, the presence of bonded resins and low cost, starch from defatted CNS can be considered as a prospective renewable material in polymer industries, with potential to compete with current feedstock such as potato and corn.  相似文献

A novel rotator trap was evaluated to determine the diel activity patterns and physiological state of adult female mosquitoes in St. Augustine, FL, U.S.A. Culex nigripalpus were most active from 19:00‐21:00, followed by 1:00‐3:00, based on collections from the novel rotator trap. Furthermore, analysis of the physiological state of female mosquitoes collected by the novel rotator trap suggested that non‐parous (nulliparous) host‐seeking mosquitoes were more frequently active in the 21:00‐23:00 and 09:00‐19:00 time frames. Parous host‐seeking mosquitoes were more frequently collected from 19:00‐21:00 and 1:00‐3:00. A low abundance of gravid females was collected by the rotator trap, so analysis of their activity periods was inconclusive. These results indicate that the novel rotated trap could be used to detect the diel activity patterns of adult mosquitoes in mosquito control programs and more testing should be conducted in the future.  相似文献

A selective medium containing a combination of starch, milk proteins, and streptomycin was used as a reliable indicator for the presence of Bacillus sphaericus in soil samples collected from a mosquito habitat where this pathogen was previously applied. The medium can also be used as an indicator substrate to retrieve B. sphaericus from infected mosquito larvae. Results show that B. sphaericus remains viable and infective 9 months after application as a larvacidal agent of mosquitoes in a roadside ditch.  相似文献

We evaluated the oviposition response of gravid Aedes albopictus (Skuse) to six organic infusions. Laboratory and field‐placed oviposition cups baited with water oak (Quercus nigra L.), longleaf pine (Pinus palustris P. Mill), or St. Augustine grass (Stenotaphrum secundatum (Walt.) Kuntze), as well as binary infusion mixtures of each, were used. In addition, a triple‐cage, dual port olfactometer was used to measure upwind response of gravid individuals to these infusions. We found that Ae. albopictus deposited more eggs in infusion‐baited cups compared with water alone. Moreover, significantly more eggs were laid in the water oak and a water oak‐pine mixture as compared with the St. Augustine grass infusion in laboratory bioassays. However, a negative upwind response was observed with longleaf pine infusion in the olfactometer. In field cages, significantly more eggs were deposited in infusion‐baited cups as compared with water alone and a greater percentage of eggs were deposited in cups containing a water oak and the water oak‐longleaf pine mixture as compared with cups containing single infusions or their mixtures.  相似文献

Multiple buds have been induced from cotyledonary nodes of cashew, Anacardium occidentale L. Maximum number of buds were initiated on Murashige & Skoog's (MS) medium supplemented with 117 mM sucrose, 14.6 mM maltose and 22.2 M BA. The buds were harvested at each subculture after elongation on MS medium supplemented with 100 ml l-1 coconut water, 14.6 mM maltose, increased sucrose (146 mM) and decreased BA (4.4 M). Excised microshoots were rooted in vitro on MS medium in the presence of 117 mM sucrose, 2.9 M IAA and 4.9 M IBA. Plantlets have been successfully transferred to soil and have been established in the field.  相似文献

Abstract The presence of aedine mosquito eggshells in soil has recently been used to delineate oviposition patterns in coastal wetlands. However, the colour of eggshells may reveal information about the oviposition activity of mosquitoes that is not evident from the density and distribution of eggshells alone. This study describes the rate of colour change of newly hatched eggshells of Ochlerotatus (Ochlerotatus) vigilax , the common saltmarsh mosquito. In March 1996, eggshells were buried in soil of five mosquito-breeding sites on Kooragang Island, NSW. Eggshells were graded by colour using Munsell® soil-colour charts. Seventy-five percent of newly hatched eggshells were black and 25% were dark brown in colour. Black eggshells faded quickly to lighter shades of brown, so that none were recovered 20 months after commencement of the study. Eggshells faded to a median of dark brown after 13 months and medium brown after 2 years. In another study, significant differences in colour frequency between existing saltmarsh and two recently created oviposition sites were found; the latter site being characterised by numerous black and dark-brown eggshells and very few light-brown eggshells. The results suggest that active and inactive oviposition sites may be identified using the frequency distribution of eggshell colours based on large numbers of eggshells, whereas the colour of individual eggshells only coarsely reflects age since eclosion.  相似文献

Lowering food consumption by larvae has been shown to (1) prolong the duration of development in Aedes aegypti, (2) increase the time elapsed between emergence of males and females, (3) produce smaller mosquitoes with a reduced lipid content per milligram of body weight, and (4) bring about a significant decrease in the percentage composition of 18:0 and 18:2 fatty acids.  相似文献

Global warming has shortened mosquitoes’ lifecycle period and increased the disease transmission rates by mosquito vectors. We reviewed only three mosquito‐borne diseases: malaria, dengue fever, and the Japanese encephalitis. Billions of people get infected with those diseases and millions of people die every year. Although we struggle to find the most effective way to control mosquitoes using various methods (including pesticides), mosquito‐borne diseases are still among the most serious problems being faced. This paper, therefore, reviews the strategies for controlling mosquitoes. The use of pesticides to control mosquitoes might have more negative effects on humans and environments than benefits. Although the development of genetically modified (GM) mosquitoes raises new hopes for effective mosquito control, it will take longer to assess the risks to humans and environments. Furthermore, there has been concern about the possible adverse effects from the release of GM mosquitoes into the environment. The various mosquito traps may not be as effective at controlling only female mosquito populations. Therefore, new strategies for the control of mosquitoes are vital. The smart mosquito counter device was developed by Korean Centre for Disease Control (KCDC) in 2013. The mosquito pest control office is able to set up the appropriate mosquito control strategies by using quantitative mosquito information. The smart device will bring mosquito control in line with modern smart generation technology and the device will also soon be able to identify different mosquito species. This new strategy will change the methods of mosquito control and will provide beneficial effects toward sustainable nature and human health.  相似文献
