Resumo

O objetivo deste trabalho foi caracterizar os aspectos biológicos e morfológicos de machos da mosca-dos-brotos Neosilba perezi (Diptera: Lonchaeidae). Em laboratório, o período de incubação dos ovos foi de dois dias, em média, com 55,5% de viabilidade. Criadas em dieta artificial, à base de farinha de mandioca, o tempo médio de desenvolvimento da larva recém-eclodida até a formação de pupa foi de 15 dias, e o período pupal médio foi de 23 dias. O ciclo biológico (ovo-adulto) foi de aproximadamente 40 dias. Os ovos são de coloração branca, forma elíptica e têm 960 ± 5,30 µm de comprimento e 290 ± 1,30 µm de largura na região central; as larvas de aspecto vermiforme, terceiro ínstar, são de coloração branco-leitosa e medem ± 10 mm de comprimento (3º ínstar).


The aim of this study was to determine biological and morphological patterns of the male shoot fly, Neosilba perezi (Diptera: Lonchaeidae). Under laboratory conditions, the incubation period of eggs took two days, on average (viability of eggs: 55.5%). Bred on an artificial diet, based on cassava flour, the mean time of development of the newly hatched larvae to pupa formation occurred in 15 days, and the average pupal period took 23 days. Finally, the biological cycle, from egg to adult, lasted approximately 40 days. The eggs are white colored, have an elliptical form and are about 960 ± 5.30 µm long and 290 ± 1.30 µm large in the central region; the vermiform larvae, third instar, are milky white and are ± 10 mm long (3rd instar).

Resumo

Differences in the phoresy of the mites Macrocheles muscaedomesticae (Scopoli, 1972) (Macrochelidae) and Uroseius sp. (Polyaspidae) on the house fly, Musca domestica (Linnaeus, 1758) and the similarities in their phoretic dispersal and parasitism are discussed, altogether with the effects on predator-prey interactions. The prevalence and intensity of phoresy in the mite species were significantly related to the attachment site on the hosts. The phoresy of Uroseius sp. was correlated with temperature but not with rainfall and relative humidity. Selective pressure in the environment resulted in displacement and the emergence of local and regional populations. These results suggest that in each habitat the populations will use different resources and will show several relationships with other species, as well as a selection for morphological and behavioral types.
