Sucking pests of brinjal cause significant losses to its yield. Considering the negative impacts of synthetic pesticides, field studies were conducted to evaluate the impact of neem Azadirachta indica, tobacco Nicotinatabbacium, trooh Citrulluscollocynthus, Movanto (Spirotetramat) against sucking insect pests of brinjal and their predators during 2016-2017. Two sprays were done during the study. Observations were taken for population reduction of insect pests due to the application of pesticides using Abbot’s formula. All the botanical pesticides especially neem showed potential to cause population reduction of aphids, whitefly, jassid and thrips. Trooh also showed significant mortality of aphid and thrips, whereas tobacco caused more mortality of whitefly and jassid. Comparatively neem showed less persistency in comparison to trooh and tobacco as mostly pest populations started rebuilding after 72 hours of its application. In comparison to Movanto, botanical pesticides particularly trooh were less toxic against the coccinellid predators i.e., C. septempunctata, B. suturalis and M.sexmaculatus recorded in the study.
