        The western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), is an important pest of horticultural and agricultural crops worldwide. The repeated use of chemical insecticides resulted in the development of insecticide resistance. We evaluated response of F. occidentalis to three synthetic herbivore-induced plant volatiles (HIPVs), methyl salicylate, methyl anthranilate, and nonanal known as attractants of thrips’ natural enemy, in Y-tube olfactometer. Mated fed adult females of F. occidentalis showed lowest response rate to methyl salicylate than methyl anthranilate, and nonanal. These results show that methyl salicylate may act as repellent to F. occidentalis, and can be used as a component of push-pull strategies for the management of F. occidentalis.

        Orius minutus (L.) (Hemiptera: Anthocoridae) is a native predators of soft body insects such as mites, thrips, and aphids.We compared 24 h consumption rate of O. minutus with that of a commercialized O. laevigatus (Fieber) on egg andadult stage of Tetranychus urticae Koch (Acari: Tetranychidae). Orius minutus predated 1.4 times more adult T. urticae(58 mites) in 24 h than O. laevigatus. Similarly, O. minutus consumed 128 eggs while O. laevigatus consumed 98 eggsin 24 h without statistical difference. These results suggest that native O. minutus can be applied for the augmentativebiological control after the development of mass-rearing method.
