dc.description.abstractStudies on „Biorational approaches for management of Callosobruchus maculatus (Fabricius) in stored mungbean‟ were carried out in Post-harvest Technology Laboratory, Punjab Agricultural University, Ludhiana, during 2017-19. Different plant oils evaluated @ 0.5, 1.0, 1.5, 2.0 and 3.0 per cent revealed that neem oil @1.5, 2.0, 3.0%, mustard oil @ 2.0, 3.0%, castor oil @ 2.0, 3.0%, soybean oil @ 3.0%, groundnut oil @ 2.0, 3.0%, karanj oil @1.0, 1.5, 2.0, 3.0 % and sesamum oil @ 3.0 % recorded significantly higher oviposition deterrence and less grain damage, weight loss, exit holes and completely inhibited F1 adult emergence. Amongst various plant powders assessed, neem kernel powder @ 3.0 and 4.0 per cent recorded significantly less number of eggs per 100 grains (3.00 and 1.33 eggs, respectively) which was statistically at par with turmeric rhizome powder @ 4.0 per cent (2.67 eggs) followed by neem kernel powder @ 1.0 and 2.0 per cent, turmeric rhizome powder @1.0, 2.0 and 3.0 per cent, dharek leaf powder, neem leaf powder and castor leaf powder. Treatments with neem kernel powder at all the concentrations successfully inhibited the F1 adult emergence and no exit holes were observed and cent per cent inhibition rate was observed. Neem kernel extract at all concentrations (1.5, 2.5, 5.0, 10.0 %) completely checked adult emergence with zero weight loss and grain damage. Storage studies on efficacy of plant oils, powders and their aqueous extracts against C. maculatus revealed that neem oil @ 3.0 per cent recorded significantly less number of exit holes/100 grains (1.33 to 13.33), adult emergence (4.33 to 15.00), per cent weight loss (0.92 to 3.10) and per cent grain damage (1.40 to 5.40). Studies on microwave assisted management concluded that eggs were the most susceptible while pupal and adult stages were the least susceptible life stages to microwave treatments. The experiment on effect of different microwave treatments on C. maculatus during six months storage showed that microwave wattages of 400 W and 600 W (each at 30 & 40 seconds exposure) and 800 W (20, 30 & 40 seconds exposure) completely inhibited adult emergence with no weight loss and grain damage. Studies on use of two-in-one model trap for management of C. maculatus revealed that treatment with storage container with one trap and sun drying for five days was most effective w.r.t. adults trapped, grain damage and weight loss. The experiment on effectiveness of bag and grain treatment with botanicals against C. maculatus in stored mungbean after nine months storage period revealed that treatment where both bag and grain treatment was done was significantly better than treatment where only grain treatment was done which was further better than only bag treatment. Neem seed kernel extract @ 10.0 per cent was significantly better in terms of exit holes, adult emergence and per cent weight loss.en_US
