Seasonal occurrence of insect pests of cashew in Bastar.

Abstract

The seasonal occurrence of insect pests of cashew at the Bastar Plateau Zone of Chattisgarh, India was investigated in 1999 and 2000. The following insect pests were recorded: tea mosquito bug (Helopeltis antonii), stem and root borer (Plocaederus sp.), termite (Microcerotermes pakistanicus), leaf miner (Acrocercops syngramma), leaf folder (Caloptilia sp.), leaf and blossom webber (Lamida moncusalis), and unidentified aphid and apple and nut borer. The tea mosquito bug, stem and root borer and termite were the dominant insects associated with cashew, with percent incidence values of 7.9-52.6, 2.5-30.0 and 5.0-50.0%, respectively. Tea mosquito bug incidence was highest in March, while stem and root borer incidence was highest in April and May. Termite incidence was high in dry and humid months. The incidence of the other pests was observed at low levels.
