A field experiment was conducted during season of 2018 at Agronomy Farm, RCA Udaipur, involving paired plot techniques for the estimation of yield loss due to major sucking pests infesting chilli ( L.). The chilli variety Pusa jwala was transplanted in 26 plots each with measurement of 3.6m x 4.2m size, with spacing of 60cm x 45cm. One set of plots were exposed to natural infestation throughout the crop growth and anther set was protected by recommended biopesticides and plant oils. The sucking pests infestation caused 27.91 per cent mean height reduction over protected plots, 31.28 per cent mean number of primary branches/plant reduction over protected plots, 35.64 per cent mean number of fruits/plant reduction over protected plots and 63.53 per cent mean yield of green chilli/plot reduction over control.
