Abstract

One of the factors that hamper the production and marketing of various agricultural crops of economic importance in Brazil is the attack of pests such as spider mites and thrips (Thysanoptera). The mite, Tetranychus urticae Koch, causes serious damage in several crops, including strawberry, peach, papaya, grapes, beans, cotton, rose, chrysanthemum, among others, in the country. The thrips Frankliniella occidentalis (Pergande) is an important pest of several crops, mostly ornamental (e.g. chrysanthemum) and vegetables. High infestations of thrips can cause significant production losses, due to the direct damage and the transmission of viruses. One of the problems faced by farmers has been the difficulty in controlling these pests through the use of agrochemicals. The biological disequilibrium caused by the elimination of natural enemies and the development of pesticide resistance in these pests are among the main reasons for this difficulty of control. The rapid development of pesticide resistance in many species of insects and mites has been a major obstacle to pest control. The objectives of the project are: 1) to study the resistance of T. urticae and F. occidentalis to pesticides in several economically important crops; 2) study the resistance of predatory mites, mainly Phytoseiulus macropilis, to acaricides and insecticides; 3) evaluate management strategies for spider mite in strawberry and ornamentals (roses) with the use of predatory mites, fungi and acaricides (synthetic and natural compounds); evaluate management strategies for F. occidentalis in ornamentals (chrysanthemum) with the use of insecticides and predatory mites (Laelapidae). For the researches on acaricide resistance in T. urticae and P. macropilis, studies on mechanisms of resistance (biochemical and molecular characterization) will be included. (AU)
