BEHAVIOR OF CALIPTRATE DIPTERA IN RELATIO N TO THE CHOOSE OF OVIPOSITION SUBSTRATES UNDER LABORATORY CONDITIONS IN RIO-DE-JANEIRO, RJ, BRAZIL

How adult females of calyptrate Diptera recognize the appropriate bree ding substrate is a matter of controversy. Among holometabolic insects , the feeding opportunities of immature stages are generally determine d 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; A therigona orientalis, Synthesiomyia nudiseta: Muscidae; Ravinia belfor ti, Parasarcophaga ruficornis, Peckia chrysostoma: Sarcophagidae) is p resented in this work. The substrate used for testing were the followi ng: bovine minced meat, fish (sardine), bovine liver shrimp, squid, hu man faeces and banana Bovine minced meat was the ovipositional and lar vipositional substrate preferred by seven species. Human faeces were p referred by R. belforti.
