[In plant distribution and biological control of aphids (Homoptera, Aphididae) on tomato]
Revista Brasileira de Entomologia 42 (1-2), 13-16
Abstract: The objective of this research was to identify Aphididae on the tomato plants and the biological control agents of these insects. This experiment was set up in completely randomized design and each experimental unit was represented by 30 tomato plants in a 1.0 x 0.5 m spacing. Macrosiphum euphorbiae (Thomas) and Myzus persicae (Sulz.) (Homoptera, Aphididae), mainly at the nymphal stage, were found and the first species was more abundant. Higher population density of these insects was found under the leaves and in the mean height of the plants. Predators, especially adults of Cycloneda sanguinea (L.) (Coleoptera; Coccinellidae), larvae of Coccinellidae beetles and adults of Condylostylus erectus Becker (Diptera, Dolichopodidae), were more effective against Aphididae than parasites. Other species of natural enemies were represented by larvae of Syrphidae (Diptera) and of Sciminus sp. (Coleoptera, Coccinellidae); adults of Vespidae (Hymenoptera) Protonectarina sp. and Polybia sp.; spiders and Braconidae (Hymenoptera).
