Effect of foliar application of selected insecticides on cocoa pollinators

Ibrahim A.G., . (1990) Effect of foliar application of selected insecticides on cocoa pollinators. [Proceedings Paper]

Cocoa flowers are generally pollinated by Forcipomyia spp Ceratopogonidae : Diptera. The widespread use of pesticides to control the cocoa pests such the cocoa pod-borer Conopomorpha cramerella would have some effect on the cocoa pollinators ivz. Forcipomyia spp. This investigation was carried out to study the effects of selected insecticides on the Forcipomyia spp. The trial was conducted in cocoa farm of Universiti pertanian Malaysia from 14th November 1988 to April 1989. The treatments used are: Gamma BHC Methamidophos Cypermenthrin and control plots no insecticide sprays. Thirty cocoa plants were sprayed with the respective insecticide at weekly interval using mist-blower. a nylon mesh was laid under the individual cocoa plant for collection of fallen flowers. The emergence boxes were placed in the treated areas for collecting of newly emerged Forcipomyia from the ground litters
