As C. chinensis selects legumes to complete its life cycle, it is an egregious pest of leguminous crops (Tuda et al., 2004). The minimum duration of the life cycle was recorded in cowpea 29±2.30 days followed by bl ack gram (30±2.34 days). 0000006338 00000 n Pupation takes place in a cell inside the seed and the pupae emerge through an exit hole made by the larvae. 0000133275 00000 n 0000006288 00000 n Callosobruchus chinensis (Coleoptera: Bruchidae) is the main pest of mungbean (Vigna radiata) especially during seed storage. 0000176649 00000 n 0000006453 00000 n Heating seeds to 50ºC for one hour kills the eggs and larvae.

Damage to the pulse grain is mainly caused by the developing larvae. Life cycle of Callosobruchus chinensis L. and its resistance to mungbean (Vigna radiata) 0000014437 00000 n Wackers, F.L., Schmale, K., Cardona, C.M. This species has a very similar lifestyle and habitat to Callosobruchus maculatusand their identities are often mistaken for each other. Although it is commonly known as the adzuki bean weevil it is in fact not a true weevil, belonging instead to the leaf beetle family, Chrysomelidae. It prefers cowpea (Vigna catjang) but it also infest the seeds of different pulses such as red gram, arhar, lentil, pea, small pea, mung, urid, moth, soyabean, khesari etc. Learn more.

The pupal stage lasts for about 4 days during summer season but in winter season this stage lasts for a considerably longer period. The female adult is slightly bigger than the male, measuring 3-4 mm in length and 2-3 mm width. Plant resistance: Certain legume varieties with thick, hairy walls are resistant to beetle infestation. and Kanwar, H.S. 0000004907 00000 n 0000003817 00000 n The emerging larvae immediately inter the pods to feed; several larvae may occur within the same seed. 0000004538 00000 n Life cycle: The pest raises 7-8 annual generations.

Development requires several weeks. Shalom Applebaum, The Robert H.

Under these conditions, females of C. chinensis were able to oviposit even after 200 days. The larvae feed on the seed leaving only the seed coat. Adult life span ranges from 5 to 15 days. 0000195420 00000 n Xianhong Zhang, College of Agronomy, Shanxi Agricultural University, Taigu, Shanxi 030801, China. 0000003972 00000 n Steve Francia, (In the past the pest was erroneously placed in the family Bruchidae). We first identified 21 OBPs and 5 CSPs of C. chinensis. There are no differences on the morphology of maxillary palp and labial palp between female and male. Eight sensillum types have been observed on the antennae of both sexes: Böhm bristles, sensilla chaetica, sensilla trichodea, sensilla basiconica, sensilla styloconicum, sensilla coeloconica, sensillum campaniformia, sensilla cavity.
