Comportamento de dípteros muscóides frente a substratos de oviposiçäo, em laboratório, no Rio de Janeiro, RJ, Brasil

ABSTRACT

How adult females of calyptrate Diptera recognize the appopriate breeding substrate is a matter of controversy. Among holometabolic insects, the feeding opportunities of immature stages are generally determined by the adult female choice of an oviposition site. The ovipositional and larvipositional substrate preference for the synanthropic flies (Chrysomya megacephala, C. putoria, Phaenicia cuprina Calliphoridae; Atherigona orientalis, Synthesiomyia nudiseta Muscidae; Ravina belforti, Parasarcophaga ruficornis, Peckia chrysostoma Sarcophagidae) is presented in this work. The substrate used for testing were the following bovine minced meat, fish (sardine), bovine liver, shrimp, squid, human faeces and banana. Bovine minced meat was the ovipositional and larvipositional substrate preferred by seven species. Human faeces were preferred by R. belforti.
