Tetranychus urticae

Fenpyroximate exhibits acaricidal and knockdown activities on phytophagous mites, such as Tetranychus urticae Koch (two-spotted spider mite) and Panony-chus citrP in citrus, apple, pear, peach, grape, etc. Fenpyroximate inhibits the mitochondrial NADH-Co Q reductase, which induces a decrease in ATP content and morphological changes in mitochondria and ultimately shows the acaricidal and knockdown activities. ...

Two examples of the remarkable potency of avermectin Bj are its LD9Q of 0.02 to 0.03 ppm against the two-spotted spider mite, Tetranychus urticae, when applied to bean plants as a foliar spray and its control of the red imported fire ant, Solenopsis invicta, when applied as a bait at a level as low as 25 to 50 mg per acre (19). [Pg.71]

Results from these laboratory studies demonstrated that avermectin Bj had high toxicity for the twospotted spider mite (Tetranychus urticae) on bean plants. When applied in solution directly onto adult and nymphal spider mite populations on foliage, avermectin Bj was shown to be 50-200 times as potent as commercially available acaricides, with an LC q of 0.02-0.03 ppm. Additional tests on foliage with insects in the order Lepidoptera, Coleoptera, Homoptera, Orthoptera, Diptera, Isoptera and Hymenoptera confirmed the broad spectrum activity and potency of the avermectin family of compounds and avermectin Bj in particular. Table II provides LC q values for avermectin Bj for the control of larval forms of several of these insects in foliar residue assays (18). [Pg.12]

Methods. Synthetic methods used to create the compounds described in this study and protocols used in the determination of toxicity to motile forms (mites) and eggs (activity expressed as LC50, ppm of foliar spray) have been published (6-10 1). The test organism was Tetranychus urticae (two-spotted mite). [Pg.325]
