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 7Â°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
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.

2013. Life cycle of Callosobruchus chinensis L. and its resistance to mungbean (Vigna radiata). Adult C. chinensis oviposit eggs on the bean surface, and the larvae then penetrate and feed on the beans. Disclaimer 9. There are no differences on the morphology of maxillary palp and labial palp between female and male. Pod infestation can start in the field before harvest, the pest thus gaining entrance into storage bins. Host plants: Beans and peas, especially chick-peas with smooth, spherical pods. 0000014408 00000 n
Several geographic strains of this species are known whose morphology is slightly different. Prevailing triple infection with three distinct Wolbachia strains was identified in Japanese populations of the adzuki bean beetle, Callosobruchus chinensis.When a polymerase chain reaction (PCR) assay was conducted using universal primers for ftsZ and wsp, Wolbachia was detected in all the individuals examined, 288 males and 334 females from nine Japanese populations.
