Taxonomic placing: Insecta, Holometabola , Coleoptera , Bruchidae. Geographical distribution : Cosmopolitan. Morphology: Adults mm long, body reddish-brown with darker spots. Larva grub whitish with a brown head. Life history: The females lay several hundred eggs, more in shelled groundnut than in tamarind and unshelled groundnuts, gluing them to the surface of the shells or kernels. The newly hatched larva burrows straight through the eggshell and pod wall, and eats the kernel, feeding only within a single seed.
Economic importance: The pest damages peanuts as well as tamarinds. Infestations cause reductions in food value, in the quality of the oil and in reduced seed germination. Such damage is particularly significant when the peanuts are destined for confectionery purposes. The heat and moisture generated by the insects increases mold growth and the development of aflatoxins in groundnuts.
The damage to seeds can be seen when infested pods are opened. Storing groundnuts in jute bags greatly restricts the movement of adults into and out of bags. Biological control : An application of an isolate of the entomopathogenic fungus Metarhizium anisopliae Metchnikoff Sorokin totally reduced progeny emergence and had some a repellent effect on the beetle. Several parasitoids attack the pest in Acacia pods, including the pteromalid Anisopteromalus calandrae Howard.
