摘要
Reproduction and development of Amblyseius alstoniae Gupta is significantly affected by temperature and relative humidity (RH), optimum being a temperature of 25-degrees-C and RH of 70%. At this combination, the viability of eggs, fecundity and daily egg production were higher, oviposition period and longevity were of longer duration, and mortality was minimal. Increase or decrease in these temperature and RH levels leads to a drop in fecundity, longevity and oviposition period and an increase in mortality. Longevity of females is always greater than that of males, irrespective of temperature and RH. Female: male ratio decreases with increase in temperature, irrespective of RH.
