Some parasitoids have been shown to serve as a biological control for Maruca vitrata. Parasitoid wasps families include Braconidae and Ichneumonidae; some parasitoid flies in the Tachinidae are also natural enemies of the moth. M. vitrata prefers to lay its eggs on the flowering bodies of the cowpea plant. Efforts have been made to deter M. vitrata from reproducing on the plant ranging from pesticides to a chemical specifically designed to sterilize the moth. Genetically modified cowpeas has been developed to express the cry protein from Bacillus thuringiensis, which is toxic to lepidopteran species, particularly to the pod borer. This technology have...
