The cotton entomofauna consists of various groups of Insects which show a distribution in strata. Except the superfamily of Chalcidoidea which offers a relatively homogeneous distribution, each group of Insects studied prospect a preferential area with particular ecologic conditions. Among these conditions the trophic relations are of the first importance. The Drosophilidae keep close to the organic matter in decomposition at the deep stratum. The phytophagous Insects live on the foliage at the medium strata. They could be hosts of parasites of some Chalcidoidea and Thecostomates or preys of some predators such as Empididae and Syrphidae. The interactions between these different Insects and vegetal are discussed. |
