  Title Role of botanical protectants and larval parasitoid Dinarmus vagabundus (Timberlake) (Hymenoptera: Pteromalidae) against Callosobruchus maculatus Fab. (Coleoptera: Bruchidae) infesting cowpea seeds Type Journal Article
  Year 2000 Publication Malaysian Applied Biology Abbreviated Journal  
  Volume 29 Issue 1-2 Pages 55-60

  Abstract The uses of plant leaf extract treated jute bags and the larval parasitoid Dinarmus vagabundus to protect the proteinaceous seeds of cowpea from the infestation and damage by the notorious seed beetle Callosobruchus maculatus were investigated. When cowpea seeds were stored in plant leaf extract treated jute bags, egg laying by the beetle and its adult emergence as well as seed damage were reduced. Treatments with 5, 10 and 15% concentrations of aqueous leaf extracts from ten indigenous plants were evaluated. Leaf extracts of A. indica, V. negundo, C. collinus and J. curcas at all concentrations were effective against C. maculatus infestation. The highest percentage of parasitism was noted when cowpea seeds were stored in A. indica and V. negundo leaf extract (5%) treated jute bags. Thus, such treatment of jute bags and introduction of parasitoid protect the cowpea seeds in storages against C. maculatus.
