Efficacy of Two-In-One Model Traps and Sun Drying against Callosobruchus Maculatus (F.) in Mungbean

Abstract

Detection of insect infestations is essential for quality assurance and helps in locating insect infestations, for early diagnosis of low-level infestation and to ascertain the success of control measures. This study evaluates the efficacy of two-in-one model trap against cowpea bruchid Callosobruchus maculatus (F.) in stored mungbean in six months of storage. Tamil Nadu Agricultural University (TNAU) developed two-in-one model traps were used. The observations on number of adult beetles trapped, % weight loss and grain damage were recorded at the end of each month, for six months. The results obtained conclude that use of one trap and sun drying of mungbean grains for five days is significantly effective in reducing the number of adult beetles. No weight loss and grain damage were recorded with this treatment, where only one trap/ container was used followed by sun drying for five days at the end of fourth month. Similar results were obtained up to six months. The % weight loss of 1.75 and 4.00% grain damage observed at the end of sixth month with one trap and three day sun drying of grains exhibit its efficacy.
