Implementation of cocoa pod sleeving in controlling cocoa pod borer infestation

Saripah B., . and I. Azhar, . (2007) Implementation of cocoa pod sleeving in controlling cocoa pod borer infestation. [Proceedings Paper]

Sleeving of fruits like guava bananas jackfruit and star fruit is effective in controlling insects pests. Similarly sleeving of cocoa pods at reasonable age is effective in reducing crop loss caused by cocoa pod borer CPB. Several sets of studies on cocoa pod sleeving were conducted in April 2004 until December 2006 at Cocoa Research and Development Center Hilir Perak Perak Malaysia in 7C 8C and 9C respectively. All of the blocks that were formerly categorized as a high-infested block with more than 85 of pods severely attacked by CPB. Average Damage Severity Index ADS/ values lower than 0.5 which fallen onto Healthy to Slight CPB Infested Blocks 28 months after the treatment were employed. Percentages of infested pods were also reduced to less than l0 in all the blocks. Comparison inter-block study between insecticide spraying and cocoa pod sleeving also conducted at Block 3E and 4E. The of ADSI value in sleeved block was lower than 0.5 which categorized into Healthy to Slight block while insecticide sprayed block suffered greater yield losses with minimum yield loss for six months data collection. Higher CPB infestation occurred in an insecticide sprayed block compared with blocks with pod sleeving which values of ADSI subjected the blocks into Light to Medium Infested Blocks. Meanwhile similar experiment that was conducted at 6B as an intra-block study showed that CPB can be managed by sleeving the pods.

Abstract

Sleeving of fruits like guava bananas jackfruit and star fruit is effective in controlling insects pests. Similarly sleeving of cocoa pods at reasonable age is effective in reducing crop loss caused by cocoa pod borer CPB. Several sets of studies on cocoa pod sleeving were conducted in April 2004 until December 2006 at Cocoa Research and Development Center Hilir Perak Perak Malaysia in 7C 8C and 9C respectively. All of the blocks that were formerly categorized as a high-infested block with more than 85 of pods severely attacked by CPB. Average Damage Severity Index ADS/ values lower than 0.5 which fallen onto Healthy to Slight CPB Infested Blocks 28 months after the treatment were employed. Percentages of infested pods were also reduced to less than l0 in all the blocks. Comparison inter-block study between insecticide spraying and cocoa pod sleeving also conducted at Block 3E and 4E. The of ADSI value in sleeved block was lower than 0.5 which categorized into Healthy to Slight block while insecticide sprayed block suffered greater yield losses with minimum yield loss for six months data collection. Higher CPB infestation occurred in an insecticide sprayed block compared with blocks with pod sleeving which values of ADSI subjected the blocks into Light to Medium Infested Blocks. Meanwhile similar experiment that was conducted at 6B as an intra-block study showed that CPB can be managed by sleeving the pods.
