V.The present investigation entitled “Dynamicsofmajorpests of soybean under different dates of sowing’’ was carried out on Experimental Farm of Agricultural Entomology, Post Graduate Institute, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (MS), India, during Kharif, 2016 to study the effect of different time of sowing on major pests, natural enemies, growth and yield of soybean under protected and unprotected regimes. The result revealed that infestation of girdle beetle, stem fly and counts of semilooper, tobacco leaf eating caterpillar and sucking pests (leafhopper & whitefly adults) and lady bird beetle (adults and grubs ) revealed significant differences among the protected regime (A1) and unprotected regime (A2) and different dates of sowing (B). The minimum infestation of stem fly was registered in the crop sown at 12th July and it was at par with 22nd July and 2nd August. While,the infestation of semilooper and girdle beetle was minimum at crop sown during 22nd July (B4) followed by 2nd August (B5) and 12th July (B3). The infestation of tobacco leaf eating caterpillar was reported to be minimum in the crop sown at 22nd June (B1) followed by 2nd July (B2). However minimum infestation of leafhopper and whitefly adults was recorded in the crop sown at 12th July (B3) and it was at par with 22nd July(B4), 2nd August (B5) and 22nd June (B1). The population of lady bird beetle was highest in the crop sown on 2nd July (B2) followed by 22nd June (B1). Among the various interactions (AXB), minimum infestation of girdle beetle (3.45 per cent) was noted in the interaction i.e crop sown at 22nd July with protected regime (A1B4) andstem fly (2.70 per cent) was noted in the interaction i.e crop sown at 12th July with protected regime (A1B3)..Minimum infestation of semilooper (0.45 larvae/mrl) was recorded in the interaction i.e. crop sown at 02nd August with protected regime (A1B5) andtobacco leaf eating (1.02 larvae/ mrl). was recorded in the interaction i.e. crop sown at 22nd June with protected regime (A1B1) .Minimum infestation of leafhopper (0.56 no./leaf) and whitefly (0.56) was recorded in the interaction i.e crop sown at 02nd August with protected regime (A1B5).The chemical insecticides used in this study revealed deleterious effect on lady birdbeetle population. The data on various growth parameters (height, number of branches, leaves and leaf area) pertaining to different dates of sowing (B) revealed significant differences among each other at various phonological stages (flower initiation ,pod initiation and pod development). However, maximum height of plant, number of branches, leaves and leaf area was registered in the crop sown at 12th July (B3) followed by 2nd July (B2) and 22nd June (B1). The number of pods , grains, weight of grains and yield was significantly higher in protected regime than unprotected regime.The higher pods (65), number of grains (146.88), weight of grains (13.25 g) and yield (23.81 qt/ha) was recorded in the crop sown at 2nd July (B2) followed by 22nd June (B1).Among the interactions (AXB) highest number of pods (65), highest number of grains (146.88), highest weight of grains and highest yieldwas recorded in the crop sown during 02nd July with protected regime (A1B2) followed by 22nd June with unprotected regime (A2B2) and at par with 12th July with protected regime (A1B3).ThesisItem Open Access EFFECT OF MAGNETIC FIELD AND DIFFERENT DIETS ON Corcyra cephalonica(Dr.Panjabrao Deshmukh Krishi Vidyapeeth, Akola., 2017-06-19) CHANDRAWANSHI, PUJA GANESHRAO.; Aherkar, Dr. S.

For ovipositional preference chickpea variety Digvijay was found least preferred followed by BDNG-2013-1 and Vijay. Whereas, BDNG-2015-2, PhuleG-D-8108 and BDNG-798 were found more preferred for oviposition. In respect of developmental preference and susceptibility BDNG-2013-1, Digvijay, Vijay, BDNG-2013-2 and Vishal were found less susceptible, while PhuleG-D-8108 and BDNG-798 were found more susceptible varieties. In Eco-friendly approach for management of pulse beetle seven eco-friendly product viz., Camphor ball @ 1.5 g/kg, Sesamum oil @ 5 ml/kg, Rice husk ash @ 20 g/kg, Neem seed kernel powder @ 5 g/kg, Castor oil @ 5 ml/kg, Asafoetida @ 5 g/kg and Cow dung cake ash @ 20 g/kg tested against pulse beetle. Among the eco-friendly products highest mortality of adult bruchids i.e. 100 per cent on 7th DAT was recorded in chickpea seeds treated with Camphor ball @ 1.5 g/kg, Sesamum oil @ 5 ml/kg and Rice husk ash @ 20 g/kg. However, Castor oil @ 5 ml/kg and Cow dung cake ash @ 20 g/kg required 11 days to complete 100 per cent mortality. Grain damage, weight loss and adult emergence (both F1 and F2 generation) was found nil in chickpea seed treated with Sesamum oil @ 5 ml/kg and lowest in Castor oil @ 5 ml/kg. Among the materials, Neem seed kernel powder @ 5 g/kg and Rice husk ash @ 20 g/kg were found less effective for adult emergence (841.67 and 943.33 adults/500g seed), seed infestation (32.24% and 33.21%) and weight loss (2.68 and 2.41%) respectively, in chickpea seeds at 75 DAT. Whereas, Cow dung cake ash @ 20 g/kg, Camphor ball @ 1.5 g/kg and Asafoetida were found intermediate group were recoded for adult emergence (334.00 adults/500 g seed, 445.67 adults/500 g seed and 630 adults/500g seeds), for seed infestation (13.60, 16.25 and 26.06%), for weight loss (1.62, 1.24 and 1.86 %) respectively. Significantly highest per cent seed germination was recorded in Sasamum oil and Castor oil upto 180 DAT. However, all the treatments were found highest seed germination upto 75 DAT but lowest seed germination was recorded at 180 DAT in the seeds treated with Camphor ball, Neem seed kernel powder, Asafoetida, Rice husk ash and Cow dung cake ash. Thus present finding indicates that Sesamum oil and Castor oil have been found as effective safe alternatives for the management of pulse beetle under storage condition.
