在整个生长季节，用三种醛和一种醇的混合物对两片烟草田进行了处理，这些醛和醇是烟芽夜蛾性信息素的成分。与传统杀虫剂处理的对照田地相比，经过信息素处理的田地中，信息素诱饵锥体诱捕器对烟草芽虫雄性的捕获量大大减少。此外，在经过信息素处理的田地里，实验室饲养的雌性被限制在交配台上，交配次数减少了 88% 至 98%。然而，有必要喷洒经过信息素处理的田地来控制烟草天蛾（Manduca sexta (L.)）和绿椿象（Acrosternum hilare (Say)）。由于这些杀虫剂处理也杀死了烟草芽虫幼虫，因此无法评估信息素处理对该物种控制的全面影响。然而，这些结果表明，在类似的补救措施可用于控制烟草天蛾和可能的其他害虫物种之前，空气渗透技术将不适用于控制烟草中的烟草芽虫。
Two tobacco fields were treated throughout the growing season with a blend of three aldehydes and one alcohol, components of the sex pheromone of the tobacco budworm, Heliothis virescens (F.). Captures of tobacco budworm males in pheromonebaited cone traps were greatly reduced in the pheromone-treated fields compared with the control field under conventional insecticide treatment. Moreover, mating of laboratory-reared females confined on mating tables in the pheromone-treated fields was reduced 88 to 98%. However, it was necessary to spray the pheromone-treated fields to control the tobacco hornworm, Manduca sexta (L.), and green stink bug, Acrosternum hilare (Say). Because these insecticide treatments also killed tobacco budworm larvae, it was impossible to assess the full impact of the pheromone treatment on control of this species. Nevertheless, these results indicate that the air permeation technique will not be adaptable for control of the tobacco budworm in tobacco until similar remedies are available for control of the tobacco hornworm and possibly other pest species.
