Tobacco thrips, Frankliniella fusca (Hinds), is a pest of cotton. Currently, growers rely on neonicotinoid seed treatments to control F. fusca. However, the occurrence of neonicotinoid‐resistant F. fusca populations has created new challenges for their management. Development of thrips‐active Cry51Aa2.834_16 Bacillus thuringiensis (Bt ) toxin expressed in MON 88702 cotton will be an important new tactic for thrips management. Previous studies have shown that MON 88702 causes limited mortality of F. fusca adults and larvae but reduces infestations on seedling cotton by suppressing oviposition from colonizing adults. This suggests that the toxin affects host preference of adult F. fusca. Knowledge of the effect of this trait on F. fusca feeding behavior provides a more complete understanding of MON 88702 activity. Using electropenetrography, we compared the feeding behaviors of adult F. fusca females on MON 88702 cotton and a non‐Bt isoline cotton over 2 h. The number of probes, proportion of probes resulting in ingestion, total duration of ingestion, and duration of ingestion per event were measured.

富兰克氏菌在表达Cry51Aa2.834_16 Bt毒素的棉花幼苗上的取食行为。
烟草蓟马（Findliniella fusca）是棉花的害虫。当前，种植者依靠新烟碱种子处理来控制F. fusca。但是，新烟碱耐药性F. fusca种群的出现为其管理提出了新的挑战。在MON 88702棉中表达的具有蓟马活性的Cry51Aa2.834_16苏云金芽孢杆菌（Bt）毒素的发展将是蓟马管理的重要新策略。以前的研究已经表明，MON 88702原因限制的死亡率F. fusca的成虫和幼虫，但减少了从殖民成年人抑制产卵育苗棉花虫害。这表明该毒素会影响成虫的寄主偏好F.福斯卡 这个特点对影响知识F. fusca的摄食行为提供MON 88702活动的更完整的理解。我们使用电晶体学比较了成年F. fusca雌性在MON 88702棉和非Bt等值棉上2 h的摄食行为。测量探针的数量，导致摄入的探针比例，总摄入持续时间和每个事件的摄入持续时间。
