Abstract:

The experiments were conducted in laboratory conditions at the Department of Entomology, Faculty of Crop Protection, Sindh Agriculture University, Tandojam. The results revealed that the above predator reared on aphid species, Lipaphis erysimi and Myzus persicae to determine the voracity and biomass consumption of larval (grub) as well as adult stages of Menochilus sexmaculatus. It has four larval instars and the third and fourth instars have the ability to consume a great number of M. persicae than the first and second instars as compare to L. erysimi. Among adults the females can consume a maximum number of aphid, M. persicae, as compared to males. The adult male and female feeding rate were higher in middle age (11-20 days) than the early or old age. It was observed that has the maximum weight gain in all larval (grub) instars and adults on M. persicae as compare to L. erysimi. The analysis of data indicated that the voracity rate and biomass consumption and daily weight gain of all larval (grubs) instars and adults were significantly different from each other (P<0.01).
