Abstract: The economic analysis of mustard aphid management on rapeseed in Chitwan district is insufficient. So, an experiment was conducted to monitor aphid population and to evaluate the economic constraints of Lipaphis erysimi (Kalt.) on rapeseed from November 2017 to February 2018. The experiment was laid out in split plot design with three replications. The three varieties (Pragati, Bikash and Unnati) of mustard is main factor and insecticidal treatment were sub factor of experiment which include i) Spinosad 45% suspension concentrates at 0.44 ml/lit of water, ii) Imidacloprid 70 water dispersible granule at 0.14 gm/ lit of water, iii) Beauveria bassiana 1.15% wettable powder at 2g/lit of water, and iv) Untreated control. The yield, biomass and Harvest Index was statistically similar among all varieties. Seeds per pod, yield, biomass, and Harvest Index was the highest with Imidacloprid followed by Beauveria, Spinosad and Control. Cost of production, net return, gross return, and B:C ratio was found maximum in Imidacloprid compared with other treatments. The highest number of aphid population was seen during the last week of December to mid-January in Chitwan. Imidacloprid was found the most effective and economically viable option for aphid management which could be a potential measure for the economic management of aphid in rapeseed in the district.
