| Izvleček: | In an insecticidal-spray evaluation programme in managing the cashew insect-pests in general, and
tea mO!lQuito bug He/ope/tis antonii Sign, in particular during 2005-2006; six schedules were taken
comprising of three-round chemical-sprays viz., Kerala state recommendation (quinalphos and carbaryl),
chlorpyriphos, triazophos, lambda-cyhalothrin, profenophos and untreated control. Sprayings were
resorted to in flushing, flowering and nut-initiation stages. Bio-efficacy of the'se pesticides were
discussed with respect to major pests-tea mosquito bug, leafminer, leaf and blossom webber, nut-borer
and thrips; natural enemies like generalist predators-ants and spiders, pest-management-economics
and the associated pesticid~-residue in the harvested cashew-nuts. Lambda-cyhalothrin was
re.commended based on its cheaper-cost and low-dose-requirement. |
