Human efforts to grow abundant food through the persistent use of resource-intensive farming practices have resulted in declining soil health, and deterioration ecosystem functions services. Conservation agriculture (CA) has emerged as a practice minimize impacts conventional resource-exhaustive energy-intensive agriculture. Minimum disturbance, permanent cover, diversification are key components CA. Tillage on other hand detrimental effects environment it requires deep inversion with instruments such mouldboard plow, disc plow etc. leaving very less organic matter after establishment crop. Even though, CA advocates many benefits over terms water conservation, consequent changes moisture temperature regimes due reduced tillage surface cover would likely going influence biological activity, including insect pests their natural enemies which dwell within these agroecosystems. The changed crop conditions under may favor particular communities ecological niches. adoption lead decrease major activity canopy. However, that spend maximum life span at or beneath increase. Recent insect-pest outbreaks North-Western India imbalances reported Indo-Gangetic Plains point need for better understanding inter-relationships between intensity, residue retention, pest population dynamics. current review analyzes existing state knowledge dynamics presents scenarios emerge get more acceptance. This will help develop countermeasures improve performance services based cropping systems.
