Female sex pheromone of cocoa pod borer moth Acrocercops cramerella: identification and field evaluation

Beevor P.S., . and Day R.K., . and Mumford J.D., . (1986) Female sex pheromone of cocoa pod borer moth Acrocercops cramerella: identification and field evaluation. [Proceedings Paper]

The cocoa pod borer Acrocercops cramerella Snellen Lepidoptera: Gracillariidae was a serious pest of cocoa in South East Asia. The sex pheromonae produced by the female moth had been shown to consist of at least five components using gas chromatography and electroantennography. These were identified and synthesised and a synthetic blend of five components in 100:10:10:1:10 ratio was used to optimise the design positioning and colour of pheromone traps for this species in Sabah East Malaysia. Subsequent experiments showed that a mixture of the five components in 40:60:4:6:10 ratio was the most attractive to male moths. Brown with 5 cm separation between top and bottom positioned just above the cocoa canopy and baited with polythene vials impregnated with 1 mg of the optimum synthetic pheromone blend caught more than twelve times as many moths as similar traps baited with a virgin female moth.

Abstract

The cocoa pod borer Acrocercops cramerella Snellen Lepidoptera: Gracillariidae was a serious pest of cocoa in South East Asia. The sex pheromonae produced by the female moth had been shown to consist of at least five components using gas chromatography and electroantennography. These were identified and synthesised and a synthetic blend of five components in 100:10:10:1:10 ratio was used to optimise the design positioning and colour of pheromone traps for this species in Sabah East Malaysia. Subsequent experiments showed that a mixture of the five components in 40:60:4:6:10 ratio was the most attractive to male moths. Brown with 5 cm separation between top and bottom positioned just above the cocoa canopy and baited with polythene vials impregnated with 1 mg of the optimum synthetic pheromone blend caught more than twelve times as many moths as similar traps baited with a virgin female moth. The paper discussed the prospects of the synthetic pheromone in monitoring and control of cocoa pod borer
