Abstract

The leopard moth Zeuzera pyrina (Lepidoptera: Cossidae) became a destructive polyphagous pest to some wood, fruit and ornamental trees. Larvae of. Z. pyrina were reared on poplar (Populus sp.) branches. Number of larvae and pupae completed their development, percentage of pupation, larval and pupal durations, rate of moth emergence, mating, oviposition, longevity, incubation period and percentage of hatchability were studied in poplar branches under mean laboratory conditions. The pre-oviposition period was only one day, the incubation period averaged 10.9 days (16 – 14 days), approximated total life cycles were 300.8 (274 - 324 days on natural host when reared on poplar. The relatively long period of larval period of infestation (248 – 289 days with an average of 271.6 days) impose the need of urgent integrated control.
