Biological polymorphisms of peptidase and α-GPDH in natural populations of the cocoa pod borer Conopomorpha cramerella snellen

The cocoa pod borer Conopomorpha cramerella (Snellen) (Lepidoptera: Gracilariidae) formerly known as Acrocercops cramerella is considered a new insect attacking cocoa in Sabah, the species being first recorded there in 1980 (M umford, 1984). Although this pest has not been found on cocoa in Peninsul...

Electrophoretic techniques permit a precise and relatively simple examination of genetic differences among individual insects and among populations of insects. Electrophoresis had been successfully used to detect the presence of sibling species complexes in several insect species such as the Drosophila willistoni group (Ayala et al.. 1972), the Simulium jenningsi group of black flies (May et al.. 1977), the Myzus persicae group of green peach aphids (May and Holbrook, 1978), the Anopheles gambiae group of mosquitoes (Miles, 1978) and the Perthida glyphopa group of leaf miners (Mahon et al ..1982).
