ABSTRACT
Pulse beetle (Callosbruchuschinesis) causes serious damage to the seed of chickpea, and other pulses during storage. Seed viability and other quality parameters are affected by its infestation. This pest is controlled by phosphine fumigation and synthetic insecticides. Unfortunately, this pest has developed resistance against these pesticides. Moreover, with application of these pesticides, chemical residues may cause severe damage to non-target organisms. Host plant resistance against insect pests is considered best ecological approach to pest management. Keeping this in consideration, the current research activity is planned to screen out available germplasm of chickpea against dhora beetle (Callosobruchuschinisensis). For this purpose, 8 genotypes of chickpea genotypes were taken from Ayub Agricultural Research Institute, Faisalabad. 1 kg of each genotype was taken in plastic jars. There were three replications of each genotype for each insect. Twenty adults of dhora beetle were discharged in each container which were enclosed with muslin cloth with rubber bands. The Jars were placed at room temperature. Data of egg laying were observed after five days of release of insects. Data of emergence F1 adults were observed after 30 days of storage. At this time percent weight loss and Seed viability was also analyzed. The Same data were observed after two- and three-month storage period. The results revealed that all the varieties/lines differed significantly from one another for percent weight loss and viability. On the basis of percent weight loss, the variety Bittal-2016 was found to be the most susceptible. Whereas the variety Niab-CH-2016 was also found to be the least susceptible. The current research found that none of the chickpea cultivars were totally resistant to C.chinensis, however their vulnerability varied significantly. Finally, the acquired data will be statistically examined for the study of variance via statistical software. Means of significant treatments will be examined at = 5% using the HSD-Tuckey test.
