dc.description.abstractInsect pests are an important biological constraint in the limiting production of groundnut. Field trails during kharif 2002, were conducted at the Research Farm, College of Technology and Agricultural Engineering, Udaipur, eleven germplasms and the local check, variety GG-2 were screened for their relative preference by the major insect pests; season al incidence of these pests was studied and the overall efficacy of different treatment combination were evaluated against these pests on variety TKG-19A. The results of seasonal incidence showed that the incidence of jassids has been maximum in the last week of August and in the third week of September; of aphid, in the third week of August and in the first week of September; of thrips, in the first and last week of September, of tobacco caterpillar and blister beetle in the third week of September. The results of varietal/germplasm screening revealed that the germplasm ICR- 10 to be least preferred while the germplasm ICR-02 to be most preferred by the groundnut jassid. The germplasm ICR –02 to be most preferred by aphid also. Whereas, variety GG-2 showed to be least preferred by aphid. The maximum hair density showed resistance against jassids and aphids. The germplasm JUN-40 was more preferred host and germplasm JAL-13 was least preferred host of thrips. The variety GG-2 showed to be least preferred by tobacco caterpillar and blister beetle, whereas, germplasms TIR-10 and UG-2 were preferred more by tobacco caterpillar and blister beetle, respectively. The insect pests of groundnut were effectively managed with monocrotophos (0.05%) than neem seed kernel extract (5%) and other treatment combinations were least effective. Monocrotophos (0.05%) proved to be the best treatment as it gave the highest C:B ratio (1:12.05), followed by neem seed kernel extract (5%) with a C:B ratio of 1:9.69 and the treatment Chrysoperla carnea @ 4000 larvae/ha was least effective, giving the C:B ratio 1:0.64.en_US
