Lucilia sericata (Meigen, 1826) (Diptera: Calliphoridae) is a synanthropic fly with worldwide distribution that pollinates plants and relevant in medical, veterinary, forensic sciences. L. diurnal species whose vision plays an important role spatial orientation. Here we evaluated the electrophysiological responses (ERG) of sericata’s compound eyes adults both sexes from Colombia their behaviora...

Host preference is an important behaviour in parasitoid females as they must choose suitable hosts for their offspring. Preference includes location, recognition and acceptance of hosts. Both genetic environmental factors can affect all those stages. Here, we focus on two (rearing history experience) affecting host the wasp genus Nasonia (Hymenoptera: Chalcidoidea: Pteromalidae: Pteromalinae), ...

We previously showed that wild-type E3 carboxylesterase of Lucilia cuprina has high activity against Type 1 pyrethroids but much less for the bulkier, alpha-cyano containing Type 2 pyrethroids. Both Types have at least two optical centres and, at least for the Type 1 compounds, we found that wild-type E3 strongly prefers the less insecticidal configurations of the acyl group. However, substitut...

Rate of development of forensically-important Diptera in southern Brazil. Dipteran larvae were collected from rabbit (Oryctolagus cunniculus L.) carcasses during the four seasons in 2005 in the southernmost state of Rio Grande do Sul, Brazil. The larvae were fed ground beef at ambient temperatures following collection from carcasses. The development of each species under these conditions was es...
