Abstract:
The experiment was carried out under laboratory conditions in which four seed protectants i.e. neem oil 0.03% EC @ 6.00 ppm, deltamethrin 2.8% EC @ 1.40 ppm, U.V. radiation @ 254 nm for 5 minutes and diflubenzuron @ 1.00 ppm were tested against pulse beetle, Callosobruchus chinensis L. on fresh chickpea seeds under laboratory conditions as a preventive measure. The standard quantity of each treatment was mixed with 500 grams of disinfected (fresh) chickpea seeds and kept in glass jars covered with muslin cloth and a sample of 25 gram each from those bulk treated fresh chickpea seeds were drawn at 24 h, 48 h, 72 h, 96 h and 120 h after exposure to various treatments and three pairs of newly emerged male and female adults were released. The adults of C. chinensis that emerged from different treatments were counted at 30, 60, 90 and 120 days interval of egg laying and kept at room temperature. The minimum adult emergence was observed when the chickpea seeds treated with deltamethrin followed by diflubenzuron and neem oil whereas maximum pulse beetle count was recorded on U.V. irradiated seeds in the samples those were drawn at various intervals of 24 h, 48 h, 72 h, 96 h and 120 hours after 30 days of storage. A similar trend was found even after 60 days, 90 days & 120 days of storage. All the treatments differed significantly among themselves and also differed significantly with control treatment. The losses were increased with increase in storage period.
