S.Abstract: The present investigation entitled “Ecofriendly management of pulse beetle in stored mung bean” were carried out during the year of 2020-2021 at Insect Physiology Laboratory, Department of Entomology, Post Graduate Institute, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The study of biology of pulse beetle revealed that the average incubation period of pulse beetle was 4.6 days. The average larval and pupal period was 22.6 days. The mean ovipositional period of female pulse beetle was 7.2 days. The mean fecundity of female was 80.6 eggs and ranged from 73 to 90 eggs. The average male and female longevity were 7.6 and 10.4 days, respectively. Total life cycle of pulse beetle was 35.8 days and ranged from 26 to 42 days. The experiment was laid in Completely Randomized Design with eight treatments, replicated thrice. One kg of mung bean seed variety Kopergoan was taken for each replication of treatment. The treatments included were sweet flag rhizome powder @ 10 g/kg seed, turmeric rhizome powder @ 5 g/kg seed, bitter gourd seed powder @ 20 g/kg seed, black pepper powder @ 3 g/kg seed, cloves powder @ 3 g/kg seed, neem leaves powder @ 20 g/kg seed, cow dung cake ash @ 10 g/kg seed and untreated control. One hundred gram of seed taken in each plastic container of 250 g capacity from one kilogram treated stored sample for two months and in which 5 pairs of adult beetles were released and stored under ambient condition. Result revealed that sweet flag rhizome powder @ 10 g/kg seed (96.67%), black pepper powder @ 3 g/kg seed (86.67%), cloves powder @ 3 g/kg seed (76.67%) and cow dung cake ash @ 10 g/kg seed (73.33%) proved best in giving highest per cent mortality of Callosobruchus chinensis L. for two months storage period. The seeds treated with sweet flag rhizome powder @ 10 g/kg seed (10.33 eggs/100 g seed), cow dung cake ash @ 10 g/kg seed (13.00 eggs/100 g seed), black pepper powder @ 3 g/kg seed (16.00 eggs/100 g seed) and turmeric rhizome powder @ 5 g/kg seed (17.00 eggs/100 g seed) were most effective in inhibiting the oviposition of beetles. For the adult emergence seeds treated with sweet flag rhizome powder @ 10 g/kg seed (4.00 adults/100 g seed), cow dung cake ash @ 10 g/kg seed (6.33 adults/100 g seed), black pepper powder @ 3 g/kg seed (7.33 adults/100 g seed) and turmeric rhizome powder @ 5 g/kg seed (7.00 adults/100 g seed) were found best during two month of storage period. Overall results indicated that sweet flag rhizome powder @ 10 g/kg seed, black pepper powder @ 3 g/kg seed, cow dung cake ash @ 10 g/kg seed were found best for pulse grain protectants which prevented the infestation and weight loss in seed for two months storage period.ThesisItem Open Access Title : EFFICACY OF INSECTICIDES AGAINST MAJOR PESTS OF SOYBEAN (Glycine max).(Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2022-07-19) Authors : KONDAWAR, ABHISHEKH SURYAKANT.; Advisor : Undirwade, Dr. D.
