Chemical control of Frankliniella spp. in rose bushes is the most common form of control used by producers of ornamental plants. To assess the insecticidal action of possible pesticides for control of thrips on roses was conducted the experiment in the field, in São Benedito, CearáState, Brazil. To control Frankliniella spp. the insecticideswere tested: neem oil emulsified (Azadirachtin), spinosad, pyriproxyfen and xylene, thiamethoxam and lambda-cyhalothrin, lufenuron, imidacloropridand beta-cyfluthrin, buprofezin, chlorfenapyr, formetanate hydrochloride and control (water). The evaluations were made 24, 48 and 72 hours after application of treatments, by direct counting of nymphs and adults at 30 flower buds (15 Direct analyzed buttons in the field and 15 individually in plastic cups of300 ml and analyzed in a controlled environment) per treatment. In general, the studied pesticides caused mortality, in the dosages used,in extreme conditions, ie inside the closed flower buds, allowing to expand the alternatives (when officially registered) for the control of Frankliniella spp.
