Management of Pulse Beetle (Callosobruchus chinensis) through Different Inert Materials and Plant Powders in Stored Black Gram

The experiments were conducted in the laboratory under the Department of Entomology, S.K.N. College of Agriculture, Jobner (Jaipur) during the period from August, 2023 to April, 2024. Out of nine inert materials, viz., talc powder, sand/ bajri, gypsum, clay, Neem kernel powder, Neem leaf powder Karanj kernel powder, Karanj leaf powder and Tulsi leaf powder two dosages were evaluated among which the maximum developmental period was recorded on Neem kernel powder 2.5 g (38.22 days). It was followed by Neem leaf powder 2.5 g (37.33 days) and Karanj kernel powder 2.5 g (36.88 days). The minimum male adult longevity was observed in Neem kernel powder 2.5 g (5.33 days), which was found at par with Neem leaf powder 2.5 g (5.65 days) and Karanj kernel powder 2.5 g (6.10 days). The minimum female adult longevity was observed in Neem kernel powder 2.5 g (5.66 days). Which was found at par with Neem leaf powder 2.5 g (6.10days) and Karanj kernel powder (6.33 days). The adult emergence was minimum in Neem kernel powder 2.5 g (0.00-2.67 adults). It was followed by Neem leaf powder 2.5 g (0.00-2.71adults) and Karanj kernel powder (0.00-3.00 adults) up to 90 days of treatment, which was found most effective. The seed damage was minimum in Neem kernel powder 2.5 g (3.00-7.33 adults). It was followed by Neem leaf powder 2.5 g (3.12-7.69%) and Karanj kernel powder (3.22-7.89%) up to 90 days of treatment, which was found most effective. The weight loss was minimum followed by Neem kernel powder 2.5 g (1.16-5.37%), Neem leaf powder 2.5 g (1.21-5.54%) and Karanj kernel powder (1.23-6.16%) up to 90 days of treatment, which was found most effective.
