The mountain farming communities of the Garhwal Himalaya rely on a conventional approach to agriculture to meet their subsistence needs. The resilience of local crop varieties plays a significant role in crop productivity in the indigenous agricultural system. In such circumstances, the protection of the crop from insect pests becomes paramount. Traditional ecological knowledge plays a crucial role in safeguarding standing crops from production losses in an environmentally benign and sustainable manner. The investigators in this study have surveyed the Mandakini valley to document the indigenous practices undertaken by the farming folks to protect the crops from pest infestation in the region. These practices are discoursed here and, further, look into the potential of natural predators as bio-control. The findings indicated that pests from the order Coleoptera had the most species, followed by Lepidoptera and Hemiptera. Most of the pests in the study site were serious defoliators, damaging the young foliage of the crops. Some entirely fed upon their roots-stems, while the rest were leaf miners and sapsuckers, thus compromising the overall well-being of the plant. In a developing country like India, there is a lack of reliable data that sheds light on the annual crop losses incurred by these pests. Thus, it becomes pertinent to compute an overall estimate of crop losses at various stages of crop production, from seed storage to post-harvest times.
