Emergence of adult pest and loss of groundnut pod in storage period
Abstract
The screening test of thirteen ground nut cultivars were conducted to study their resistance and susceptibility to Caryedon serratus in the laboratory at 70% RH and 28 ± 1°C. The successful development of adult beetles widely varied from 0.0 to 29.0 after one month. The variety OG 52-1 proved to be immune to the attack up to one month of storage. Percentage of weight loss due to beetle infestation was varied from 1.2 to 17.8% in first month of storage. The cultivar OG 52-1 recorded least weight loss.
