• The developmental period, fecundity and diapause attribute of a synthetic pyrethroids-organophosphate-carbamate resistant strain (SEL10) of the predatory mites, Amblyseius womersleyi SCHICHA were compared with several indigenous strains. There was little difference in the developmental periods at 25℃ between four strains. The fecundity was compared between five strains using the number of eggs oviposited for 3 days by ten females at 5-6 days after adult emergence. The fecundity of the SEL10 strain was significantly higher than that of the HK and FL94 strains. There was a large variation in the diapausing rate at 18℃ under 9L-15D between strains. The strains (OKI and ISHI) originating from Okinawa Prefecture showed a very low diapausing rate. Hatchability and survival rates were more than 90% and 85%, respectively, regardless of the crossing. No reproductive incompatibility was observed at inter-strain crossing. This indicates the possibility of breeding a new resistant strain of A. womersleyi by hybridization and selection for release into deciduous fruit trees or into glasshouses with short day length.
