Pest Status of Stored Chickpea Beetle, Callosobruchus chinensis Linnaeus on Chickpea

Muhammad Aslam

Abstract

To determine the pest status of Callosobruchus chinensis Linnaeus (CCL) (Coleoptera:Bruchidae) on chickpea, samples of chickpea were collected from different sources (the farmers, the villagers and general public homes). From each area/location three points were selected to collect the samples with the help of probe. From each collected sample 100 grains were examined. While collecting the samples, the temperature and humidity of the site from where the samples were collected were recorded with the help of portable thermohygrometer. Based on the samples collected, the percent infestation to the chickpea by this pest recorded was 12.18 with standard deviation of 05.42. Based upon the percent infestation, the insect was declared as major pest of chickpea, as it caused more than 10% damage to chickpea. Moreover, it was also concluded from the discussion that the damaged grains did not remain fit for human as well as animal consumption due to the bad smell created by the attack of the pest.
