Effect of Distance from Wetland Borders on Hymenopteran Wasps and Spider Abundance in Maize-soybean

The non-crop residences within agroecosystems are main resources for ecological and organic insect bug management. Diversified cropping arrangements are known to influence contagions populations, however, by what method neighboring residences to the agricultural fields influence insect pest open enemies populace dynamics is not clear. This study directed on understanding the influence of wetland approximates Hymenoptera wasps and predatory spider predominance in a maize-soybean intercrop system. The Hymenoptera wasps and spiders culture estimates were carried out in duodecimal farmers’ fields stratified inside 0-300 and 500-1100 meters from the wetland borders. Data were composed once a week offset one period from the emergence of maize and soybean plants until post-flower development of the two crops. Results demonstrated crop fields within 0-300 meters from the swamp borders had significantly higher numbers of wasps and spiders, while crop fields start at 500-1100 meters from the wetland borders, the community of Hymenoptera wasps and spiders was significantly reduced. The verdicts of this study display that stable habitats in the way that wetland borders harbour taller numbers of natural enemies of crop blights and crop fields at close proximity benefit from active migration of organic enemies from the pool in stable residences. These findings maybe used to design field architectures such as field margins or borders that can support bug pest open enemies survival and shift into crop fields.
