Abstract

The mating, blood feeding and oviposition of Simulium takahasii (Rubtsov), an anautogenous, multivoltine Japanese blackfly, were observed in the laboratory. The results showed that this species readily mates in captivity, and when a male and a female were put together in a small polystyrene tube, the insemination rate was 100% (of 43 pairs examined). In addition, blood feeding was successfully induced on a man's hand and a rabbit's ear on the day of emergence. Fifteen (14.7%) of 102 females fed on a hand, while 6 (37.5%) of 16 females fed on a rabbit. Three or 4 days after the blood feeding, oviposition was observed with 11 inseminated females. However, 2 females which had not been inseminated failed to oviposit. A mean of 158 eggs was laid by a female which had fed on a man, whereas 195 eggs were deposited by a female which had fed on a rabbit. Five to 12 days after oviposition, 80.9-97.9% of eggs laid by 7 females hatched, although the rate was only 38.3% with an egg batch laid by 1 female. Thus, it was found that S. takahasii is a candidate species suitable for laboratory colonization.
