Life Table of the Green Lacewing Apertochrysa sp. (Neuroptera:Chrysopidae) Reared on Rice Moth Corcyra cephalonica(Lepidoptera: Pyralidae)

The survivorship from egg to adult emergence and fertility of Apertochrysa sp. fed on Corcyra cephalonica were studied in laboratory and population parameters of Apertochrysa sp. were used for construction of life table under ideal condition in laboratory free from natural enemies. The highest mor...
