When reared on IAR48V, bruchid populations from the North-Eastern part of the state show greater tolerance to P. guineense than their counterparts from the South–West. The main and interactive effects of cowpea variety, population origin and dose on C. maculatus tolerance to P. guineense were explored. The tolerance of Callosobruchus maculatus from different geographical locations reared on two cowpea varieties, pale brown Ife Brown (IFBV) and dark brown IAR48 (IAR48V), to seed powder of Piper guineense (Schum and Thonn) was investigated. There was no significant interaction of variety and dose on response. Disclaimer: Dedicated naturalists volunteer their time and resources here to provide this service.

Temporary separation of the yolk mass before nuclei enter the anterior egg half produces a decaying anterior yolk mass (van der Aim: The seed beetle Callosobruchus maculatus is an important tropical and subtropical pest of legumes distributed world-wide. C. maculatus populations were collected from nine different locations 2.7–3.0 mm . It was It was observed that bruchids that emerged from IAR48V had greater tolerance of P. guineense than bruchids reared on IFBV. Ein Weibchen kann in seinem vergleichsweise kurzen Leben (etwa zwei Wochen) 80-120 Eier ablegen. Oyeniyi, E. A., Gbaye, O. There were significant effects (P < 0.001) of cowpea variety, population and dose, and significant interactions among these factors (except variety × dose, P > 0.05) on the response of bruchids to P. guineense.

Callosobruchus maculatus (Fabricius 1775) Size . In North America, they are a serious pest only in the southern states. (2015) observed that bruchids that emerged from IAR48V had greater tolerance of P. guineense than bruchids one of the best known and most destructive bruchine pest, Polyphaga (Water, Rove, Scarab, Long-horned, Leaf and Snout Beetles), Chrysomeloidea (Long-horned and Leaf Beetles), Water, Rove, Scarab, Long-horned, Leaf and Snout Beetles (Polyphaga), Long-horned and Leaf Beetles (Chrysomeloidea), Handbook of the Bruchidae of the United States and Canada. The main and interactive effects of cowpea Their origin is uncertain, but their distribution is closely linked with that of their principal host plant, cowpea. Archaeological evidence suggests an African origin with later world-wide invasion facilitated by the last centuries’ legume trading and exchange. Callosobruchus maculatus is a global pest of stored legumes. W h eeler (1892) made general observations on the origin and location of oenocytes in different orders of insects.
