Bionomics of the <I>Ailanthus</I> Leaf Roller <I>Psorosticha zizyphi</I> Stainton (Lepidoptera: Oecophoridae)

Abstract

Ailanthus leaf roller Psorosticha zizyphi Stainton is a new record on Maharukh, a nutritious fodder tree. The moths appear each year in January and oviposit singly. Incubation period is 3-4 days, larval period ranges 14-16 days, pupal period is 6-8 days. Life cycle varies from 23-28 days. Foliar spray of 0.25% malathion and 0.005% Fenvelarate in April/May gave effective control of the pest. The fodder can be used for livestock after fifteen days of spraying.
