杀虫剂抗性是节肢动物害虫物种长期关注的问题，这可能导致杀虫剂控制失败。尽管如此，几十年来，杀虫剂抗药性一直是关注的焦点，但杀虫剂控制失败的风险却被忽视了。认识到这两个问题是至关重要的节肢动物害虫管理，特别是当入侵物种众所周知难以控制和展示频繁的杀虫剂耐药性的情况下被认为是。这就是假定的粉虱种中东-小亚细亚I（MEAM 1）（烟粉虱B型）的情况，在新热带区几乎没有信息。因此，可能发生的7种杀虫剂的抗性水平进行了调查，巴西种群的这一物种。还确定了该物种登记的五种杀虫剂控制失败的可能性。检测到对所评估的所有杀虫剂的抗药性，所有这些杀虫剂的抗药性都达到高水平（即> 100倍）至极高水平（> 1000倍）。生物杀虫剂印楝素的总体效力特别低（25%）和频繁（70%），其次是螺甲螨酯和三氟氯氰菊酯。相比之下，丁醚脲（主要是吡虫啉）防治失败的可能性较低。由于杀螟丹和氯虫苯甲酰胺不是用来对付粉虱的，而是经常用于同一种寄主植物，因此可能发生了无意的选择，导致了高水平的抗药性，特别是对氯虫苯甲酰胺。杀螟丹和氯虫苯甲酰胺的抗性水平与吡虫啉的抗性水平相关（r>0.65，P
Insecticide resistance is a standing concern for arthropod pest species, which may result in insecticide control failure. Nonetheless, while insecticide resistance has remained a focus of attention for decades, the incurring risk of insecticide control failure has been neglected. The recognition of both problems is paramount for arthropod pest management and particularly so when invasive species notoriously difficult to control and exhibiting frequent cases of insecticide resistance are considered. Such is the case of the putative whitefly species Middle East-Asia Minor I (MEAM1) (Bemisia tabaci B-biotype), for which little information is available in the Neotropics. Thus, the likely occurrence and levels of resistance to seven insecticides were surveyed among Brazilian populations of this species. The likelihood of control failure to the five insecticides registered for this species was also determined. Resistance was detected to all insecticides assessed reaching instances of high (i.e. >100x) to very high levels (>1000x) in all of them. Overall efficacy was particularly low (25%) and frequent (70%) for the bioinsecticide azadirachtin, followed by spiromesifen and lambda-cyhalothrin. In contrast, the likelihood of control failure was low for diafenthiuron, and mainly imidacloprid. As cartap and chlorantraniliprole are not used against whiteflies, but are frequently applied on the same host plants, inadvertent selection probably took place leading to high levels of resistance, particularly for the latter. The resistance levels of cartap and chlorantraniliprole correlated with imidacloprid resistance (r>0.65, P
