| Abstract | ||
| Soybean plants are afflicted by many pest species. The current study was conducted at Assiut experimental farm in the 2022 and 2023 seasons. The results showed twenty-six species of insect pests pertaining to ten orders and eighteen families were collected from the soybean crop in Assiut city at different stages of growth. This study revealed that a total of 15 species of pests were found in soybean plants. Whitefly, Bemisia tabaci was the most dominant of these pests at all, followed by thrips tabaci (Lindeman), plant bug (Phytocoris spp.), and jassid, Empoasca spp., then come Aphis gosspyii (Glover), Myzus persicae, and Nazara viridula (Linné), while, Eysarcoris inconspicuous (Westwood)and Nysius graminicola (koienati) were the least economically important for this crop. Eleven predator species pertaining to five orders and seven families were found to feed on soybean insects. Among them, six are significant; these are specifically Campylomma impicta (Meyer) Coccinella undecimpunctata (Linnaeus), Chrysoperla carnea (Stephens), Cydonia spp. and Orius spp., in addition to true spiders. An essential part in managing insect pests of soybeans is played by these natural enemies. In all cases the dominance degrees of pests were higher than those of the predators. Through these results, it is clear that natural enemies can be included into an integrated pest management program under the weather condition of Assiut city. | ||
