Callosobruchus maculatus (Fabricius) (Coleóptera: Bruchidae) With 5 textfigures Introduction Very little work has been done on the origin, arrangement and the meta- morphic behaviour of oenocytes in Coleóptera. C. maculatus populations were collected from nine different locations across Osun state in the South Western part of Nigeria. Ein Weibchen kann in seinem vergleichsweise kurzen Leben (etwa zwei Wochen) 80-120 Eier ablegen. Callosobruchus maculatus besitzt eine enorme Reproduktionsfähigkeit mit sehr kurzen Entwicklungszyklen. Die Käfer stammen ursprünglich aus Westafrika.

W h eeler (1892) made general observations on the origin and location of oenocytes in different orders of insects. Diese sind klein und weißlich und werden einzeln an Bohnenkerne geheftet. D. P.

Egg maturation starts before emergence from the seed and, provided Archaeological evidence suggests an African origin with later world-wide invasion facilitated by the last centuries’ legume trading and exchange.
