Just after hatching young larvae bores into the grain, feed upon the contents of the grain making them almost hollow and empty. The threshold of development is at 7°C, and the development of a generation requires 560 day-degrees. Callosobruchus chinensis Linnaeus. The adults, which do not feed, live for less than one week and are capable of flight. Callosobruchus chinensis is reported for the first time from wild host legumes in Okayama, Japan, in 1985. 1958 0 obj <>stream Callosobruchus chinensis (Linnaeus) (Coleoptera, Bruchidae) is a destructive pest of stored food, and is widely distributed around the world. Occasionally pupation may take place outside the grain in a cocoon made of excretory matter. After copulation and fertilization, the eggs are laid singly but several of them can be seen on one grain.

Pod infestation can start in the field before harvest, the pest thus gaining entrance into storage bins.
