Diversity of Invertebrates Living on Greenhouse Tomato Crops on the Azzefoun Region (Tizi-Ouzou, Algeria)

Abstract

Cultivated environments provide a habitat as well as various food resources for alarge number of species of invertebrates, which can be phytophagous, predators andparasites, which act as natural enemies of agricultural pests, thus constitutingmeans of biological control in agrosystems. An inventory of invertebrates, inparticular arthropods, was made during the greenhouse tomato cultivation season ofthe Dawson variety in the region of Azeffoun, on the coast of Kabylia. The use of thesweep net, Barber pots and aerial or colored traps allowed us to capture 76 speciesdivided into 46 families, belonging to 16 orders and 06 classes of invertebrates.Values of the Shannon diversity index are quite high, they vary from H'= 2.68 bitsto H'= 4.84 bits. The equitability obtained for each type of trap varies from E=0.53to E = 0.87. These values tend towards 1, which reflects a balance between thespecies living in the tomato crop.
