Abstract
Developmental studies of E. pariyarensis were carried out in the laboratory at a temperature of 25 + 2o C and 30 + 2o C under 65 + 10 RH. Regular observations were made to collect data on various aspects of breeding viz., mating, pre-oviposition, oviposition, post- oviposition, fecundity and total longevity of both male and female predatory mites preying upon various stages of pest mite, Tetranychus neocalidonicus. The developmental duration of all stages was seen to be influenced by temperature. The active stages of larva, quiescent phase of deutonymph and total developmental period were found slightly decreased with increase in temperature from 25 to 300C (P<0.05). The preoviposition period, oviposition period, post ovipositon period and total longevity were found to vary with the increase in temperature whereas fecundity did not show significant difference (P<0.05).
