Abstract

STUDIES OF CALLlPIIORIDAE (DII'TERA), OF TIIE RIO URUCU BASIN, CEN· TRAL AMAZONIA. Calliphoridae 01' lhe rcgion 01' lhe uppcr Urucu river basin, Wesl 01' lhe cily ofManaus, Amazonas Slale, Brazil, were sludied considering composilion and abundance 01' lhe species. capturing 14729 spccilllen dislribuled as tollows: Cochli- omyill mllcellllria (Fabricius) (12643), Chloroprocta idioidea (Robincau-Desvoidy) (1667), Phaellicia eximia (Wiedemann) (354), Hemilucilia semidiaphallo (Rondani) (54), H segmelltaria (Fabricius) (6), CII/ )'som)'a puLoria (Wiedemann) (I) e C. albiceps (Wiedemann) (I). The resulls shaw lhal Cochliomy ia macel/aria has a facility lo adapl rapidly to an environmenl changed by man. The làcl that was registered two specil11en of C/J/ysomya Robincau-Desvoidy in highly isolaled localities contribuled to show the ability ofthese tlies ;n exploring the available Illcchanisms lo rcach remote places, re-el11phasizing lhe concepl ofhigh capacity of expansion Of lhis species. The possibilities 01' colonizalion Oflhis area by pioneer species 01' C/I/:vsomya was discus- sed, considering the local environl11enlal condilions. The imponance 01' sludies 01' endemic calliphorids flies in arcas wilhoUl presence 01' pioneers, in order 10 bettcr understand lhe mechanisl11s 01' adaplalion used by lhese species were slriked.
