  2. 2. INTRODUCTION Pulses belong to family Leguminosae and they are excellent an inexpensive source of plant protein andprovide a balanced diet for millions of people when eaten in when combination with cereals. . The pulse beetle, Callosobruchus analis (Fabricius) Coleoptera: Bruchidae) is the pest of mung (Vignaradiata), mash (Phaseolus mungo), moth (Phaseolus aconitifolius), peas, cowpeas and other pulses. Both the larvae and the adults cause damage. The larva is recognized by its creamy-white, oval, flabbybody. The adult is an oval beetle,. The female is chocolate with a black trapezoidal area surrounding by whitestreaks on the three sides. This area is located in the centre of each elytra towards the outer margin. The young larva on emergence bores into the grain and feeds entire contents

  4. 4. MATERIALS AND METHODSThe present studies on “Effect of plant oils on adult emergence, fecundity and weight loss ofcollosobruchus analis (fab.) in green gram (vigna radiata l. roxb). , the expriment were carried out underlaboratory conditions in postgraduate laboratory of Entomology Department, Faculty of Crop Protection,Sindh Agriculture University, Tandojam. The culture of C. analis was obtained from grain storage laboratory, Tropical Agriculture ResearchInstitute,Karachi University . Four different plant oils i.e. mustard (Brassica compestris ), coconut (Cocus nucifera), sesame(Sesamumindicum) and rocket seed (Eurica sativa) which are commercially available in market were purchasedandmixed with gree n gram grains. The standard concentration of each oil was 0.25 ml and which was mixed with the 250 grams of greengram. Weighted green gram grains were kept in plastic jars which were covered with muslin cloth and bandedwithrubber strips. The experiment was replicated four times and control (without treated grains). The culture wasdeveloped for

  10. 10. CONCLUSIONS All the plant oils were comparatively better for keeping the pulse beetle belowinfestation level. Rocket seed oil (Jambho) proved more effective among the other oils. Population of adult emergence and fecundity increases the peak in the month ofAugust and September months. The minimum weight loss was found in Rocket seed oil in green gram. The maximum weight loss was found in control treatment in green gram. The temperature 39oC and humidity 64% was found favourable for pestmultiplication.
