Biology of Pulse Beetle (Callosobruchus chinensis) and Its Management through Plant Products on Black Gram (Vigna mungo)
Journal Title: STAR Journal - Year 2013, Vol 2, Issue 1
Abstract
Laboratory studies on the biology of the pulse beetle Callosobruchus chinensis (Linn.) (Coleoptera: Bruchidae) on the stored black gram revealed that the insect completed six generations from April to October. Total developmental period of bruchid was 31 days during July – August while it was 38.3 days during April – May. On an average the incubation, larval, pupal and total developmental period (egg to adult) was of 8.0, 18.39, 8.11 and 34.5 days respectively. Five plant powders viz., neem (Azadirachta indica A. Juss) leaf, black pepper (Piper nigrum L) fruit, aonla ( Emblica officinalis L) fruit, five leaved chaste tree(Vitex negundo L) leaf, curry leaf tree (Murraya koenigii (L.) leaf, at 50g/ kg grains and two oils, viz., mustard(Brassica juncea L) and neem seed kernel oil used at 7.5 ml/kg grains were tested for their efficacy as grain protectants against the pulse beetle infesting black gram(Vigna mungo(L) Hepper). The results revealed that black pepper fruit powder, neem oil and mustard oil caused 100 percent mortality following 7 days exposure, thereby minimizing the weight loss of seeds as a result of pest infestation at 0, 0.22 and 0.45 per cent respectively as against 38.33 percent in the untreated control.
