“…3). Segundo Jácome et al (1999), as populações de moscas-das-frutas são direcionadas pela combinação simultânea de efeitos, tanto de disponibilidade de recursos alimentares e substratos de oviposição, como de efeitos negativos de fatores de mortalidade como os bióticos e abióticos. Então, a busca por alimento faz com que as moscas invadam os pomares, não só para procurarem sítios de oviposição, como também, para se alimentarem e acasalarem.…”

“…Provavelmente isso aconteceu com A. obliqua, o que é justificável por tratarse de espécie polífaga e predominante no Amazonas. A invasão de adultos em épocas sem plantas hospedeiras pode ocorrer em função da procura de alimentos, como foi discutido por Jácome et al (1999). A maior quantidade de moscas foi coletada na época de maior precipitação, registrando-se baixa correlação (r = 0.22, P > 0,05) entre o número de mosca/armadilha.dia (MAD) e a precipitação.…”

-The population fluctuation of (não identificada).Foi demonstrado que o fator mais importante na determinação da ocorrência e da flutuação populacional de moscas-das-frutas é a disponibilidade de frutos hospedeiros e não fatores abióticos. Registrou-se uma baixa correlação (r = 0,0748, P > 0,05) entre o número de moscas/armadilha.dia (MAD) e a precipitação. A época de maior precipitação coincide com o período de maior frutificação. Provavelmente, fatores não avaliados como a disponibilidade de hospedeiros alternativos, de inimigos naturais e sucessão hospedeira exerceram influência na população de moscas nesses locais. Este é, provavelmente, o primeiro registro de A. zernyi para a Região Norte do Brasil. PALAVRAS-CHAVE: Insecta, mosca-das-frutas, ecologia, Amazônia O conhecimento da flutuação populacional e a época de maior ocorrência de uma determinada espécie de inseto de importância econômica é um requisito indispensável para o estabelecimento de um controle eficiente e racional, pois permite viabilizar o planejamento de estratégias de manejo mais eficazes.A flutuação populacional das moscas-das-frutas varia, dependendo da época do ano, do local e da disponibilidade de frutos hospedeiros não obedecendo, portanto, a um padrão pré-estabelecido. Dois fatores são básicos para tais variações:

“…For some tephritids, ingestion of protein can also affect longevity. Access to protein has been reported to increase longevity in A. serpentina ( Jácome et al , 1999 ), whereas, in C. capitata , the results have been highly variable Maor et al , 2004 ). Recent laboratory studies on fertile and sterile Queensland fruit flies (Tephritidae: Bactrocera tryoni ; 'Q-fly') have found that continuous post-teneral access to a protein source, yeast hydrolysate, can increase mating propensity and longevity in both males and females ( PerezStaples et al , 2007b ).…”

1 Recent studies have shown that continuous access to a protein source (yeast hydrolysate) can greatly enhance the sexual performance of male Queensland fruit flies ( Bactrocera tryoni ; 'Q-flies'). However, in Sterile Insect Technique programmes used to eradicate or suppress wild populations, mass-reared Q-flies are typically fed only sucrose and water for up to 2 days before release. 2 We investigated whether adding a protein source to the diet of male Q-flies for a 24-or 48-h window after emergence and then removing it is sufficient to enhance mating probability, latency to mate, copula duration, probability of sperm storage, number of sperm stored, female remating tendency and longevity of male Q-flies. 3 Protein-fed males were more likely to mate than males fed only sucrose, especially when young. Protein-fed males also had shorter mating latencies and longer copulations than protein-deprived males. 4 Females mated by protein-fed males were more likely to store sperm, stored more sperm and were less likely to remate than were females mated by proteindeprived males. Females were also less likely to remate if their first mate had been large. 5 Overall, providing male Q-flies access to a protein source for a 24-or 48-h window early on in their adult life was sufficient to greatly enhance all assessed measures of performance. Although 24-h access was sufficient for a notable enhancement, further benefits were evident in males provided 48-h access. 6 The results are discussed in terms of the practical implications for Sterile Insect Technique programs used to eradicate or suppress wild Q-fly populations.

“…This result is interesting because according to Heimpel & Rosenheim (1995), a honey fed female will consume a smaller number of immature hosts and consequently there would be an increase in their reproductive success, since this will allow larvae development that could be used for oviposition. Reasons to explain these results are not very clear, we believe that female parasitoids that fed on honey were satiated and as a consequence they change their feeding behavior consuming less eggs and larvae (Jácome et al 1999). Other possibility is that honey in combination with the protein of prepupae and pupae was enough to supply the nutritional requirements of the parasitoid (Jervis & Kidd 1986).…”

Revista Brasileira de Entomologia 56(1): 95-100, março, 2012 The coffee berry borer (CBB), Hypothenemus hampei (Ferrari) (Coleoptera, Curculionidae), is the most important insect pest for coffee growers in tropical America. This species spends most of its life feeding inside the coffee berries, affecting the quantity and quality of coffee. Cephalonomia stephanoderis Betrem (Hymenoptera, Bethylidae) is an African parasitoid that has been introduced in several Latin American and Caribbean countries during the past 20 years for biological control of H. hampei (Barrera et al. 1990a(Barrera et al. , 1990bMurphy & Moore 1990;Baker 1999). C. stephanoderis is a solitary ectoparasitoid that attacks eggs, larvae, prepupae and pupae of H. hampei. Female parasitoid enters into the infested fruit through the CBB entrance hole and if there is enough host population, it establishes there permanently. The female parasitoid feeds on all developing stages of the coffee borer and starts parasitizing prepupae or pupae only until it has developed mature eggs. After the onset of the oviposition period, parental females remain with their broods until completion of offspring development. Young C. stephanoderis females disperse after mating and search for new hosts to repeat the cycle. It is assumed that females can feed on sugary substances if the searching period is prolonged. It takes from 16 to 20 days at 27°C for the parasitoid to develop from egg to adult. Female parasitoids live longer than males, and oviposit an average of 66 eggs during a lifetime of 80 days (Barrera et al. 1989(Barrera et al. , 1993Abraham et al. 1990;Lauzière et al. 2001).Several field studies have been performed to assess the impact of inoculative and inundative releases of C. stephanoderis Influence of age and diet on the performance of Cephalonomia stephanoderis (Hymenoptera, Bethylidae) a parasitoid of the coffee berry borer, Hypothenemus hampei (Coleoptera, Curculionidae) ABSTRACT. Influence of age and diet on the performance of Cephalonomia stephanoderis (Hymenoptera, Bethylidae) a parasitoid of the coffee berry borer, Hypothenemus hampei (Coleoptera, Curculionidae). The importance of age and feeding on the performance of Cephalonomia stephanoderis (Hymenoptera, Bethylidae), a parasitoid of the coffee berry borer, Hypothenemus hampei (Coleoptera, Curculionidae) was investigated in the laboratory. Groups of female parasitoids were subject to the following treatments: a group fed during one, five and ten days after emergence of adults with coffee borer larvae; another group fed only with honey solution during five days after emergence; and as a control, a third group was kept without food for five days. At the end of each treatment, survivorship, parasitoid activity (walking and flying capacity in an arena), search capacity for finding coffee borer-infested berries, host feeding and oviposition (on immature hosts), were assessed. Unfed females showed a significant decrease in survivorship compared to individuals that were fed. The type of meal (insec...
