      The study on estimation of economic decision levels of aphid, Aphis craccivora Koch on cowpea, Vigna unguiculata (Linn.) Walp. (grown for vegetable) was conducted at SKN College of Agriculture, Jobner. The highest net return (Rs. 11044 ha-1) was obtained from the plots where the aphid population was at 7.71 aphids per central shoot followed by 27.02 aphids per central shoot (Rs. 9674 ha-1). The correlation analysis showed a significant inverse correlation between aphid population and the pod yield of cowpea (r = -0.98). The gain threshold and EIL was found to be 213.60 kg ha-1 and 16.18 aphids per central shoot, respectively. The ETL was worked out to be 14.63 aphids per central shoot at the current market prices.
