在室内试验中，西部花蓟马Frankliniella occidentalis （Pergande）田间种群对观赏植物常用的四类杀虫剂表现出高度的抗性。对拟除虫菊酯、氯菊酯和联苯菊酯的抗性比（LC90时RR）非常高，与敏感品系（UC89）相比，抗性倍数为138倍（联苯菊酯，SD-1） ~ 8716倍（氯菊酯，SD-1）。丁酰胡椒酯对氯菊酯的增效作用高达50倍（SD-2），表明混合功能氧化酶是整个抗性机制的一个组成部分。对氨基甲酸酯类灭多威有中高强度的抗性；RR值从41倍（SD-1）到378倍（SD-2）不等。田间对有机磷毒死蜱的抗性相对较低，相对抗性值为17倍（Santa Barbara-2 [SB-2]）至31倍（SD-2）。阿维菌素（一种大环内酯）虽未登记用于西花蓟马防治，但表现出低至高水平的抗性（RR值为18倍[SD-1]至798倍[SB-1]）。对阿维菌素耐药性的发展是该领域对该化学品耐药性的第一个有记录的病例。在SB-1进行的另一项现场试验中，包括毒死蜱（微胶囊制剂）在内的所有化学品的测试效果都很差。调整后的最大控制率仅为53% (Pounce)，证实了该温室所测试的所有杀虫剂的田间失败。对常用杀虫剂的抗药性和失去更多登记的可能性强调需要更好和实用的虫害管理战略。
Field populations of western flower thrips, Frankliniella occidentalis (Pergande), showed high levels of resistance in laboratory tests to four classes of insecticides commonly used for insect control in ornamentals. The resistance ratios (RR at LC90) to the pyrethroids permethrin and bifenthrin were very high, ranging from 138-fold (Bifenthrin, San Diego-1 [SD-1] location) to 8,716-fold (Permethrin, SD-1) compared with a susceptible strain (UC89). Piperonyl butoxide significantly synergized permethrin up to 50-fold (SD-2), indicating that mixed-function oxidases are a component of the overall resistance mechanism. There was moderate to high intensity of resistance to methomyl, a carbamate; RR values ranged from 41-fold (SD-1) to 378-fold (SD-2). Field resistance to chlorpyrifos, an organophosphate, was comparatively low, with the RR values ranging from 17-fold (Santa Barbara-2 [SB-2]) to 31-fold (SD-2). Although not registered for western flower thrips control, abamectin (a macrocyclic lactone) showed low to high levels of resistance (RR values ranging from 18-fold [SD-1] to 798-fold [SB-1]). The development of resistance to abamectin is the first documented case of resistance to this chemical in the field. In a separate field trial conducted at SB-1, all the chemicals tested including chlorpyrifos (microencapsulated formulation) performed poorly. Maximum adjusted control was only 53% (Pounce), confirming the field failure for all the insecticides tested at this greenhouse. Resistance to commonly used insecticides and the likelihood of losing many more registrations emphasize the need for better and practical pest management strategies.
