Abstract
Ecological engineering is a relatively new concept of environmental manipulation for the benefit of humans and the environment. Field study involved habitat manipulation based on growing nectar producing flowering plants (preferably alfalfa, cowpea and marigold) combined with border plants on the chilli bounds, reducing the intensity of pesticide use against thrips, Scirtothrips dorsalis in chilli crop. Studies were conducted in two consecutive seasons for kharif 2020 to rabi 2020-21. Results of the field trial indicated that the lowest thrips population and high natural enemies were recorded in model 4 comprising the basal application of FYM + vermicompost + neem cake, chilli + marigold intercropping (5:1) on par with model2 (no./leaf) [FYM + vermicompost + neem cake, chilli + Alfalfa, sorghum (border crop)] followed by model 2 [FYM + vermicompost + neem cake, chilli + Alfalfa, sorghum (border crop)], sorghum (border crop) and in model 8 (chilli alone planted plot) observed maximum population of S. dorsalis and less natural enemies presented. Finally, the research concluded habitat manipulation is not a ‘high-tech’ approach so is simple and practical for vegetable farmers to implement and reduce the pesticides risk.
