Incidence of Insect Pests on Ber (Zizyphus jujube) Tree

摘要

This study was undertaken to document the prevalent insect pests fauna on some ber trees causing considerable damage to matured plants. Field trials were established in farmer's fields where commercial ber varieties were grown. Insect population counts were taken every 15 days before and after flowering and fruiting stages in each unit. The results showed highest fruit fly population and infestation in that area. Amongst other insect species attacking ber tree were certain caterpillars, weevils, beetles, and mite. The fallout from this study emphasized the importance of field scouting to determine pest populations and their well timed control.
