Abstract: Sugarcane (Saccharum officinarum) is one of the most important commercial crop produced in the state of Bihar. Biology, life history, preliminary behaviour of mating and egg laying and laboratory rearing of Pyrilla perpusilla walker (Homoptera: Lophopidae). The bug is one of the serious insect pests of sugarcane in Rampur-Rudra, Bihar. Female Pyrilla perpusilla has a pre oviposition period of 8.8 ± 1.077 days and the average fecundity was 133±10.2 eggs. Eggs are laid in clusters on both the lower (abaxial surface) and upper surface (adaxial surface) of sugarcane leaves preferably on lower surface and are covered with white waxy filaments. The eggs are white, oval and have a mean length of 1.04±0.148mm. Incubation period was 6.9±0.87 days in the field conditions and 6.8±0.81 days in cage conditions. There were five nymphal instars and nymphal phase was 40-60 days. Longevity of the adult female was significantly greater than that of males. Analysis of aggregated sampling data for males and females showed that the sex ratio was 1:1.
