"Efficacy of a cry1Ab Gene for Control of Maruca vitrata (Lepidoptera: Crambidae) in Cowpea (Fabales: Fabaceae)"^^ . "Cowpea [Vigna unguiculata (L) Walp.] is an important staple legume in the diet of many households in\r\nsub-Saharan Africa. Its production, however, is negatively impacted by many insect pests including bean pod\r\nborer, Maruca vitrata F., which can cause 20–80% yield loss. Several genetically engineered cowpea events\r\nthat contain a cry1Ab gene from Bacillus thuringiensis (Bt) for resistance against M. vitrata were evaluated in\r\nNigeria, Burkina Faso, and Ghana (West Africa), where cowpea is commonly grown. As part of the regulatory\r\nsafety package, these efficacy data were developed and evaluated by in-country scientists. The Bt-cowpea lines\r\nwere planted in confined field trials under Insect-proof netting and artificially infested with up to 500 M. vitrata\r\nlarvae per plant during bud formation and flowering periods. Bt-cowpea lines provided nearly complete pod\r\nand seed protection and in most cases resulted in significantly increased seed yield over non-Bt control lines.\r\nAn integrated pest management strategy that includes use of Bt-cowpea augmented with minimal insecticide\r\ntreatment for protection against other insects is recommended to control pod borer to enhance cowpea\r\nproduction. The insect resistance management plan is based on the high-dose refuge strategy where non-Btcowpea\r\nand natural refuges are expected to provide M. vitrata susceptible to Cry1Ab protein. In addition, there\r\nwill be a limited release of this product until a two-toxin cowpea pyramid is released. Other than South African\r\ngenetically engineered crops, Bt-cowpea is the first genetically engineered food crop developed by the public\r\nsector and approved for release in sub-Saharan Africa."^^ .
