The objective of this study was to evaluate the effect of different temperatures with the association of the mite Acarophenax lacunatus (Cross & Krantz) on the population suppression of Rhyzopertha dominica (Fabricius). The experimental units were petri dishes containing 40 g of whole wheat grains (13% moisture content) infested with 10 adults of R. dominica, under the temperatures of 20, 25, 30 and 35 masculineC, with or without A. lacunatus, in five replicates. Relative humidity of 60 +/- 5% and escotophase of 24h were used for all temperatures. Five days after the infestation, five mites were inoculated in each experimental unit. The evaluations were carried out at 20, 40, 60, 80, 100 and 120 days after R. dominica infestation. The interaction of the temperature with the parasite A. lacunatus was an important tool for the population suppression of R. dominica. In temperatures higher than 25 masculineC, however, despite the reduction of the immature stages of R. dominica, there was a high grain weight loss after 120 days. The maintenance of the temperature of the wheat grains stored at 20 masculineC can be used to complement the biological control of R. dominica with A. lacunatus. 相似文献

The aim of the present study was to assess the effect of six different temperatures on the development of Acarophenax lacunatus (Cross & Krantz) using eggs of Tribolium castaneum (Herbst) and Cryptolestes ferrugineus (Stephens) as hosts. The temperature affected the development of A. lacunatus. The largest values for the progeny (19 mites in T. castaneum and 15 mites in C. ferrugineus) were obtained at about 30 degrees C, as also observed for the net reproductive rate (Ro), which revealed that the A. lacunatus population increased 18 times in T. castaneum and 14 times in C. ferrugineus in a generation. The intrinsic rate of increase (r m) gradually increased with temperature, reaching the maximum value at 35 degrees C in T. castaneum (1,608) and C. ferrugineus (1,289). The generation time was negatively correlated with temperature, ranging from 1,60 to 4,85 days in T. castaneum and from 1,96 to 5,34 days in C. ferrugineus. These results suggest that the mite A. lacunatus may be used in programs of biological control of T. castaneum and C. ferrugineus in the tropics. 相似文献

The present study intended to verify which factors (phylogenetic relationship or local ecological conditions) would determine how Frieseomelitta bees use floral resources. The data obtained in the literature on biocenotic studies of Apoidea visiting flowers in Brazil were analyzed, with identification and quantification of floral resources used by Frieseomelitta species in different areas. The phenogram of similarity on use of resources among Frieseomelitta species was compared to the phylogenetic hypothesis proposed for the group. Among the eight Frieseomelitta species registered in 19 studies, F. doederleini (Friese), F. francoi (Moure), F. languida Moure, F. varia (Lepeletier) e Frieseomelitta sp. nov., were collected using resources from 36 plant families. F. doederleini, F. languida e F. varia centralized their activity in Caesalpiniaceae, Malpighiaceae e Anacardiaceae. The similarities and disparities found among areas and Frieseomelitta species reflected the similarities and differences of the vegetation composition in each area. Frieseomelitta bees presented a forage pattern similar to that one presented by other highly social bees, visiting flowers of many plant species, but concentrating their activities in few plant species. Despite the low phylogenetic relationship between F. languida and F. doederleini, they showed a high similarity on the use of floral resource, while F. varia e F. languida, species with high phylogenetic relationship, showed low similarity in the use of resource. Although the data obtained are not conclusive, it indicates that phylogenetic restrictions do not influence the pattern of use of floral resource by Frieseomelitta bees. 相似文献

A research about arthropode fauna in laying hen excrement was carried out in a poultry house in the State of S?o Paulo, from January 2001 to December 2002. The objective was to verify the frequency of Diptera and Coleoptera collected by Berlese funil and flutuation methods, and to show correlation between the collect methods and sazonality possible in the currents seasons. A total of 29,499 insects were collected from seventy five collects, being 16,702 Diptera (six families) and 12,797 Coleoptera (four families). Some arthropodes presented direct relation with the collect method, the seasons of the years and the rainfall precipitation, with significant increase in the number of insects collected in certain periods of the year. 相似文献

This research intended to evaluate the development of Zabrotes subfasciatus (Boh.), a stored-grain pest, on bean genotypes (Phaseolus vulgaris L.) commonly cultivated in the State of Parana and containing arcelin, and the possible resistance of these genotypes to the bruchine. Tests were performed under laboratory conditions (27 masculineC, fotophase 12h, 50 +/- 10 % RH) with the genotypes TPS-Bionobre, IAC-Una, IPR-Uirapuru, IAPAR 44, IPR Juriti, IAPAR 81, Pérola, Carioca, Bolinha, and two others containing arcelin, Arc 1 and Arc 2. The genotypes with Arc 1 and 2 alleles caused higher mortality of immature stages; in Arc 1 developmental period was prolonged and the male and female dry weights were the lowest, suggesting an antibiosis mechanism of resistance. Non-preference for oviposition was not observed for these two genotypes. Among varieties without arcelin, IAPAR 44 was the most resistant to the bruchid, being the least preferred for oviposition, and promoting low percentage of viable eggs, long developmental period and reduced male and female adult dry weight. Perola, IPR Juriti and Bolinha with high number of eggs and viable eggs, low mortality of immature stages, were the most susceptible. 相似文献
