Southern green stink bug, Nezara viridula (L.) and redbanded stink bug, Piezodorus guildinii (Westwood) are two of the most important seed sucking pests affecting Louisiana soybean production and rice stink bug, Oebalus pugnax (F.) is an important late season pest in Louisiana rice. Exploration of chemicals that exhibit attraction or repellent activities toward major stink bug species would be beneficial in developing push-pull strategies. Spinosad is a commercially available natural insecticide that may have arrestant, attractant, or phagostimulant properties against stink bugs. To test this, a series of laboratory experiments were conducted to investigate the tactile, olfactory, and feeding responses of these stink bugs toward two commercial spinosad products (Entrust and Tracer) and technical grade spinosad. In tactile assays, female and male redbanded stink bug were arrested by Entrust, Tracer, and technical grade spinosad, whereas only rice stink bug and southern green stink bug males were arrested by Entrust. Y-tube assays revealed no attraction to any of the products by either male or female rice stink bug, redbanded stink bug, or southern green stink bug. In paired (treated or untreated soybean seed) feeding preference experiments, southern green stink bug showed no preference for any treatment, whereas redbanded stink bug fed more on Entrust- and Tracer-treated seed. From these results, spinosad appears to have an arrestant and phagostimulant effect on redbanded stink bug in the laboratory.

评估选定的臭虫（半翅目：五足科）对多杀菌素的行为反应

南方绿臭虫 Nezara viridula (L.) 和红带臭虫 Piezodorus guildinii (Westwood) 是影响路易斯安那州大豆生产的两种最重要的种子吸食害虫和水稻臭虫，Oebalus pugnax (F.) 是重要的晚季路易斯安那州水稻中的害虫。探索对主要臭虫物种表现出吸引或排斥活动的化学物质将有利于制定推拉策略。多杀菌素是一种市售的天然杀虫剂，可能具有针对臭虫的逮捕剂、引诱剂或吞噬剂特性。为了测试这一点，进行了一系列实验室实验来研究这些臭虫对两种商业多杀菌素产品（Entrust 和 Tracer）和工业级多杀菌素的触觉、嗅觉和进食反应。在触觉分析中，雌性和雄性红带臭虫被 Entrust、Tracer 和工业级多杀菌素捕获，而只有水稻臭虫和南方绿臭虫雄性被 Entrust 捕获。Y 型管检测显示，雄性或雌性稻臭虫、红带臭虫或南方绿臭虫对任何产品均无吸引力。在配对（处理或未处理的大豆种子）喂养偏好实验中，南方绿臭虫对任何处理都没有偏好，而红带臭虫对 Entrust 和 Tracer 处理的种子的喂养更多。从这些结果来看，多杀菌素似乎对实验室中的红带臭虫具有逮捕和吞噬作用。Y 型管检测显示，雄性或雌性稻臭虫、红带臭虫或南方绿臭虫对任何产品均无吸引力。在配对（处理或未处理的大豆种子）喂养偏好实验中，南方绿臭虫对任何处理都没有偏好，而红带臭虫对 Entrust 和 Tracer 处理的种子的喂养更多。从这些结果来看，多杀菌素似乎对实验室中的红带臭虫具有逮捕和吞噬作用。Y 型管检测显示，雄性或雌性稻臭虫、红带臭虫或南方绿臭虫对任何产品均无吸引力。在配对（处理或未处理的大豆种子）喂养偏好实验中，南方绿臭虫对任何处理都没有偏好，而红带臭虫对 Entrust 和 Tracer 处理的种子的喂养更多。从这些结果来看，多杀菌素似乎对实验室中的红带臭虫具有逮捕和吞噬作用。
