【 摘 要 】

The pest-Aphids are a focus of attention because of the damage and losses they cause in various crops, especially in horticultural crops, mainly by the transmission of viral diseases, resulting in a decline in the quality and quantity of the harvest. The objective of this work was to explore the parasitic complex associated with aphids in crops and adjacent vegetation, which could provide shelter to entomophagous insects. This can be of vital importance for the aphid fauna present in an agroecosystem and the conservation of biodiversity. Several vegetable crops such as cucumber, peppers, eggplant, cabbage, radish and okra, as well as maize as barrier crop and adjacent weeds were sampled weekly. The samples, consisting of both live and mummified aphids, were collected from 30 plants at random, placed separately into plastic bags and brought to the laboratory. Plants with aphid colonies were placed into plastic cages to obtain parasitoid adults for their identification. The exploration resulted in the identification of species of the primary parasitoids Lysiphlebus testaceipes (Cresson) and Diaretiella rapae (Mc Intosh) (Hymenoptera: Braconidae: Aphidiidae) as well as revealed the presence of hyperparasitoids including representatives of the genus Pachyneuron (Hymenoptera: Chalcidoidea: Pteromalidae).
