Insects Diversity In Soybean Crops Under Organic And Conventional Farming

Summary

In the conditions of the Right-Bank Forest Steppe of Ukraine (Kyiv region), diversity of entomocomplex in organic soybean fields was investigated. Biodiversity indexes (Shannon’s and Simpson’s) were calculated. It was found that the total number of individuals, species and families was higher in organic fields on 88.5, 68.0 and 122.2%, compared to conventional respectively and on 33.3, 9.1, 20.7% in the protective forest plantations adjacent to the organic fields compare to conventional, respectively. Pests from 13 families were identified. On fields with conventional technology pests from 9 families were found (on 2.3% less from all individuals). It was investigated that the share of insect pests in protective forest plantations adjacent to organic fields was on 16.9% lower than in those adjacent to conventional fields. The values of biodiversity indexes in organic landscapes are greater.
