dc.description.abstractThe present investigation on "Bio-efficacy of diatomaceous earth against pulse beetle, Callosobruchus chinensis (L.)” was carried out under laboratory conditions at Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur during 2020-21. The study on biology of pulse beetle (C. chinensis) on various pulse host viz. green gram, black gram, chickpea, cowpea, pigeon pea, kabuli gram and lentil under laboratory conditions revealed that the order of host preference was cowpea (97.67) > green gram (97.33) > pigeon pea (95.67) > chickpea (89.00) > black gram (86.33) > kabuli gram (78.67) > lentil (73.33) in terms of mean fecundity by female. The mean incubation period and larval-pupal period on green gram, black gram, chickpea, cowpea, pigeon pea, lentil and kabuli gram were 4.33 and 18.67; 5.00 and 26.33; 4.67 and 21.67; 4.33 and 18.33; 4.67 and 21.00; 4.33 and 20.33; 4.67 and 26.00 days, respectively. The maximum adult survival was recorded on chickpea (90.37 %) followed by green gram (86.77 %), cowpea (84.87 %), pigeon pea (83.14 %), kabuli gram (81.34 %), lentil (79.85 %) and minimum on black gram (72.95 %). The different organic products evaluated against pulse beetle infesting chickpea in storage condition showed that diatomaceous earth @ 4 per cent was found most effective treatment in management of pulse beetle with highest adult mortality (73.33 %), lowest grain damage (6.67 %) and lowest weight loss of grains (2.00 %) and it was significantly at par with diatomaceous earth @ 3 per cent and diatomaceous earth @ 2 per cent. The next effective treatments were diatomaceous earth @ 1 per cent followed by neem seed kernel powder @ 1 per cent, mustard oil @ 2 per cent, groundnut oil @ 2 per cent and neem leaf powder @ 4 per cent. All the treatments were found to be superior over control in terms of increasing the adult mortality, reducing grain damage and weight loss.en_US
