Detalhes bibliográficos
Resumo:The objectives of this study were to identify: (1) the most abundant thrips species in blackberry, blueberry and strawberry crops, comparing its abundance between cultivars and crop plants localization; (2) weed species that may contribute to the presence of thrips and auxiliary insects in the crops. Thrips samples were taken from the crops and weeds using beating and washing methods. Thrips tabaci Lindeman was detected in the majority of the plants and this species was one of the most abundant species in the three crops. Thrips flavus Schrank was the most abundant species in blackberry and blueberry crops. Drepanothrips reuteri Uzel was only found in blackberry plants. Frankliniella occidentalis (Pergande) might have been introduced when the strawberry crop was planted. Lavatera cretica L., Lupinus luteus L. and Sinapis alba L. may bring risks to the crops, because they are possible repositories of T. flavus and T. tabaci. Arctotheca calendula (L.) Levyns, Crepis capillaris (L.) Wallroth, Geranium dissectum L., Geranium molle L., Leontodon sp., Malva parviflora L., Senecio gallicus Chaix and Poaceae plants were identified as possible repositories of thrips, which might serve as alternative preys to auxiliary insects. Aeolothrips Uzel (Thysanoptera) and Orius Wolff (Hemiptera) species, referred as thrips predators, were identified.
