Spatio-temporal variability in insect dynamics under conservation agriculture-based cropping systems

In order to meet the rising need for edible grains induced by a mushrooming human population over the past few decades, agriculture has undergone a modernization from traditional to contemporary. Monoculture, which is utilized in contemporary agriculture for intensive grain production system, requires a lot of land preparation, application of pesticides and fertilizers. These processes further imbalances the already weak below-ground and above-ground networks of agroecosystem and also worsen many benefits provided by biodiversity within agroecosystems, such as those related to biological control. As a result, conservation agriculture has been actively advocated as a useful alternative to tillage-based conventional agriculture and a crop husbandry practice that may reconcile these occasionally conflicting objectives. Conservation agriculture is a management strategy that permits permanent soil cover, minimize soil disturbance and, enhance spatio-temporal crop species diversity by the use of sustainable farming methods, which are encouraged as a means of reducing climate change and might also facilitate pest management. The author cites relevant research showing how arthropod pests and natural enemies are influenced by conservation agriculture practices, which not only have a bearing on pest management but also reduce the effects of climate change. Literature analysis reveals crop diversification, particularly the introduction of perennial species, cover cropping, tillage techniques that preserving crop residue, the use of organic fertilizers like compost, manure, and water management techniques are all promising methods for reducing pests and enhancing biological control. These techniques can strengthen crops’ resistance to insect attacks and broaden natural enemies’ diversity, thus reducing the impact of climate change on the breakdown of biological regulation.
