Bitter gourd (Momordica charantia L.) is one of the valuable cucurbit vegetables which is used as fresh and dry food, pickles and its seed contains 32% oil (Tindall, 1978).It is a source of vitamins (B and C), minerals (Iron, Calcium and Phosphorus), protein and is highly effective in controlling the diabetes (Yuwai et al., 1991).Bitter gourd is attacked by different insect pests determined whether the test insect is a pest (feeds on plant) or a predator (feeds on other insects). Pest: Defender ratio (P: D ratio): Identifying the number of pests and beneficial insects helps the farmers to make appropriate pest management decisions. Sweep net, visual counts etc. can be adopted to arrive at the numbers of pests and defenders
