DEVELOPMENT OF A CONTROL STRATEGY FOR GROUNDNUT LEAFMINER ON GROUNDNUT

This is a SADC funded collaborative project between researchers in the Department Crop Science and Production Grain Crops Institute at Potchefstroom in South Africa. The overall objective of the project is to provide data that will lead to the development of an integrated pest management (IPM) programme for groundnut leaf miner (Aproaerema modicella ( Deventer) (Lepidoptera: Gelechiidae. The groundnut leafminer (GLM),) is an important pest of groundnut (Arachis hypogaea L.) in South and South-East Asia. In recent years it has been reported in some African countries ( Uganda, Malawi, Mozambibique South Africa and Botswana). It causes severe damage to groundnut crops. The damage on groundnut leaves results in poor groundnut growth production and causes yield loss under heavy groundnut leaf miner infestations. To limit losses in yield, the insect needs to be controlled. There are no threshold levels established for control of this pest. Producers currently do not control the pest because no insecticide is currently registered for control of this pest in groundnut in South Africa and Botswana. It is hoped that the results from this project will increase and stabilize groundnut yields in smallholder farming systems in South Africa and Botswana. It is anticipated that the results will also be applicable to other SADC countries with similar environmental conditions.
