“…INTRODUÇÃO Paralelos entre as vantagens da cooperação na alimentação dos insetos podem ser feitos com os benefícios da formação de bandos em mamíferos que caçam conjuntamente, em que os indivíduos são incapazes de explorarem adequadamente os recursos alimentares sem assistência(Alexander, 1974). A interação social é um fator importante no consumo de alimento por moscas-das-frutas(Cresoni-Pereira & Zucoloto, 2005;Zur et al, 2009), por exemplo, cuja ingestão é maior em moscas pertencentes a um grupo do que em moscas solitárias. O crescimento reduzido de insetos em pequenos grupos pode refletir uma ingestão ou uma assimilação reduzida do alimento.…”

o malogro dos ovos e os efeitos dos inimigos naturais constituem fortes pressões seletivas na manutenção da agregação de ovos e larval em A. monuste orseis, a qual confere uma melhor performance do ponto de vista bi-trófico, bem como maior probabilidade de sobrevivência individual sob o ponto de vista tri-trófico. Palavras-chave: curuquerê da couve, Brassicaceae, comportamento gregário, performance, interações tri-tróficas. xi ABSTRACT SANTANA, A. F. K. Influence of larval aggregation on life-history traits of Ascia monuste orseis (Godart, 1819) (Lepidoptera, Pieridae). 2012. 76 p. Thesis (Doctorate) -Faculdade de Filosofia, Ciências e Letras de Ribeirão Preto, Universidade de São Paulo, Ribeirão Preto, 2012.In insects, the gregarious habit has been shown to improve foraging and defense against predation to both larval and adult stages. Egg clusters could also be beneficial through increased larval hatching. In this study, we tested the hypothesis that egg clusters and larval aggregations of the neotropical butterfly Ascia monuste orseis (Godart, 1819) (Pieridae) -a subspecies that uses Brassicaceae as hosts -lead to several benefits from both bi-and tri-trophic perspectives. Larval and adult performances, food assimilation by the larvae, egg viability, as well as protection against natural enemies were assessed from individuals reared either isolated or aggregated.The behavior of larval aggregations was also examined with respect to predation risk, as well as the corresponding larval defensive behaviors after enemy attack. Four treatments with different larval aggregation sizes were assigned (1, 7, 15 e 30 larvae) to assess larval performance and food utilization in the laboratory. In the field, three treatments were assigned (1, 10 e 50 larvae) to evaluate the effects of group size on predation and parasitoidism. Egg performance was examined through egg clusters of different sizes in a greenhouse. Gregarious larvae developed faster, especially in early instars, and became more fecund females than solitary larvae; however, the latter attained larger body size than the former. Under laboratory conditions, survival did not differ among treatments. Lower food ingestion per capita was observed in gregarious larvae, with no cost in food assimilation. The viability of eggs increased as egg aggregation size increased. The lower per capita predation in larger larval aggregations than smaller groups conferred higher protection to A. monuste orseis larvae against natural enemies, through the dilution effects among individuals of the group.Parasitoidism was more intense in small-sized larvae while late instars were more susceptible to predators, regardless of aggregation size. Similar to species with solitary xii habit, behavioral events which involved head movements as searching and feeding were more dangerous to A. monuste orseis larvae compared to resting and walking.Presumed defensive behaviors were observed in all instars and treatments. Thus, the benefits of aggregation in A. monuste orseis can be seen especially in ...

A new adult diet formulation was evaluated for sterile Anastrepha ludens (Loew) and Anastrepha obliqua (Macquart) males at the emergence and release facility of fruit flies in Mexico. The formulation consists of hydrolyzed protein, sugar, juvenile hormone analogue methoprene, and water. The proportion of the ingredients between the solute (4% hydrolyzed protein and 96% sugar) and solvent (10% methoprene and 90% water) was 5:1. This new formulation was called the 1:24 formulation. The main objectives of this study were to develop a simple way to supply the 1:24 formulation to adults and to compare the sexual performance of these flies with the performance of flies fed a standard diet (called the Mubarqui formulation) used at the emergence and release facility of fruit flies in Mexico. The preparation, time, and cost also were evaluated. The results showed no significant differences in the sexual behaviors of the males (number of males mating, number of males calling, mating latency, and mating duration) between the 1:24 formulation and the Mubarqui formulation. However, the cost and the required preparation time are much lower for the 1:24 formulation process than for the Mubarqui formulation process. Based on these results, we recommend the 1:24 formulation as an additional adult diet option in the handling of sterile flies. Its application is practical and does not require changes in packaging systems. The contribution of our findings and their potential application to the improvement of the sterile insect technique are discussed.
