Description

The oviposition and egg development of wild female Simulium ochraceum were observed under various constant temperature conditions (15,18,21 and 24℃) in the laboratory. Forty-seven (55.3%) out of 85 blood-fed females successfully oviposited in small tubes; a mean of 82.5% of their mature ova were laid. Hatching occurred in 34 (72.3%) of 47 egg batches laid. Ovulation and egg development rates were more depressed at 24℃ than at lower temperatures. The rate of egg development became higher as temperature increased, with the mean time (±SD) required being 9.8±0.65,7.2±0.27,5.6±0.50,and 4.2±0.27 days at 15,18,21 and 24℃, respectively. Infection with Onchocerca volvulus larvae did not affect oviposition and fecundity of the fly. The fecundity correlated with body size (expressed as the cube of wing length) of the female.
