Abstract

The experiment was conducted at research farm of Department of Agricultural Entomology, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, Maharashtra, India. during Rabi season 2020-21. Ten different varieties of mustard were screened for resistance/susceptibility against major insect pests of mustard under field conditions results unfolded that variety Giriraj could be an auspicious source of resistant against major insect pests of mustard, however, in specific, PM-26, PM-28 and Giriraj had better control over leaf webber Crocidolomia binotalis (Zeller), mustard sawfly Athalia lugens proxima (Klug) and aphids Liphapis erysimi (Kalt.), respectively. NRCHB-101, RH-74944 and ACN-09 were deemed to be susceptible cultivars against major insect pests of mustard. Mean population of mustard aphid, leaf webber and saw fly on different varieties were in the range of 6.32 to 14.08 aphids / 5 cm terminal shoot, 0.18 to 1.23 larvae / plant and 0.18 to 1.08 larvae / plant, accordingly.

Conclusion

The outcomes of the current study exhibited that having Giriraj variety in mustard cultivation could be a greater advantage against major insect pests’ infestation among the subjected cultivars. When it comes to the individual pest suppressing, varieties Giriraj, PM-26 and PM-28 displayed relatively high resistance against aphid, leaf webber and saw flies, respectively. NRCHB-101, RH-74944 and ACN-09 were appeared to be vulnerable to pest attacks. All other remaining varieties fell in intermediate positions. Employing varietal resistance in crop production aids in higher production of mustard along with reducing the use of hazardous chemical pesticides and intern environmentally friendly.
