Studies on the impact of IPM and non-IPM practices were carried out during rabi season 2018-19 at College of Horticulture, Venkataramannagudem, West Godavari district, Andhra Pradesh with an objective of examining their influence on pest complex and determining pesticide residues. The results revealed that the mean population of jassids (Amrasca devastans devastans) was 2.82 number per okra leaf in IPM plot, whereas in the non-IPM and control plots it was 5.43 and 8.46 number per leaf. Similarly, the maximum mean population of whitefly (Bemesia tabaci) was recorded in okra grown in control plot with 4.54 number per leaf followed by non-IPM plot with 1.17 number per leaf and 0.42 number per okra leaf in IPM plot of okra. The minimum average population of aphids was observed in okra grown in IPM plot with 0.27 number per leaf followed by non-IPM plot with 1.11 number per leaf, whereas in control plot it was 2.79 number per leaf. The average population of two spotted mites per sq.cm leaf area was 0.54 number in IPM plot, whereas it was 1.03 and 4.04 number per sq.cm leaf area in non-IPM and control plots of okra respectively.
