An experiment was conducted to study the feeding potential of Cryptolaemus montrouzieri Mulsant on different species of mealybugs at Department of Agricultural Entomology, College of Agriculture, Dapoli. The feeding potential of C. montrouzieri on grubs and adults of mealy bugs jointly revealed that the total consumption of grub was much higher on M. hirsutus i.e. 144.4±15.64 with their longevity of 12.10±2.1 days than Phenacoccus solani and custard apple mealy bugs. Similar pattern of consumption was found in case of adults, where the female predator consumed more i.e. 443.90±27.13 with longevity of 27.45±1.08 days. The overall findings of the feeding potential showed that the Australian ladybird beetle nymphs and adults consumed more number of preys of M. hirsutus than other two species.

Abstract


An experiment was conducted to study the feeding potential of Cryptolaemus montrouzieri Mulsant on different species of mealybugs at Department of Agricultural Entomology, College of Agriculture, Dapoli. The feeding potential of C. montrouzieri on grubs and adults of mealy bugs jointly revealed that the total consumption of grub was much higher on M. hirsutus i.e. 144.4±15.64 with their longevity of 12.10±2.1 days than Phenacoccus solani and custard apple mealy bugs. Similar pattern of consumption was found in case of adults, where the female predator consumed more i.e. 443.90±27.13 with longevity of 27.45±1.08 days. The overall findings of the feeding potential showed that the Australian ladybird beetle nymphs and adults consumed more number of preys of M. hirsutus than other two species.
