| Abstract | ||||
| The experiments were conducted to study the role of predatory insects in regulating the population of the main insect pests that attacking eggplant (Solanum melanogena L.) crop under open field conditions. The results showed the presence of nine predators belonging to four orders: Order Copleoptrea; Coccinella undecimpunctata (Linnaeus); Exochomus nigromaculatus (Goeze); Scymnus sp.;and, Hippodamia convergens (Family: Coccinillidae), Order Heteroptera; Orius spp. (Family: Anthocoridae) and Nesidiocoris tenuis (Family: Miridae) Order Diptera; Aphidoletes aphidimyza (Rondani) (Family: Cecidomyiidae) and Syrphus sp < em>. (Family: Syrphidae) and finally, Order Nuroptera; Chrysoperla carnea (Stephens) (Family: Chrysopidae). The highly average numbers and ratios of the insect predators associated with eggplant insect pests were recorded by Syrphus sp.and presented by 92.2 individuals (14%). A. aphidimyza, C. undecimpunctata and E. nigromaculatus recorded 86.7, 83.5 and 80.9 individuals respectively, and presented by 13%, 13% and 12%, respectively. While, Orius sp < em>. and C. carnea recorded the smaller numbers and represented by 54.6 individuals (8%) and 51.9 individuals (8%) during the study season. | ||||
