The aphid, Acyrthosiphon pisum population and seed yield of fenugreek had a significant inverse correlation (r = -0.94). The gain threshold and EIL was found to be 94.72 kg ha−1 and 9.48 aphids/central shoot, respectively, whereas, the ETL was found to be 5.18 aphids/central shoot at the current market prices.
