Studies on the screwworm fly Cochliomyia hominivorax in Libya: effect of temperature on pupation and eclosion.
The American screwworm fly Cochliomyia hominivorax has recently been reported in Libya (El-Azazy 1989). Fly larvae were cultured on blood agar at different temperatures (-5 degrees, 5 degrees, 18 degrees, 20 degrees, 30 degrees, 37 degrees, or 40 degrees C). Larvae pupated at 18 degrees, 20 degrees, 30 degrees, or 37 degrees C, and the highest pupation (100%) occurred at 20 degrees C. Adult flies emerged from pupae that were maintained at 18 degrees, 20 degrees, 30 degrees, or 37 degrees C; the maximal eclosion (94%) occurred at 20 degrees C. Correlation of these findings with meteorological temperature data from local areas in which C. hominivorax myiasis occurs suggests a crucial role for temperature in the determination of the effective environment for this fly species.
