Resumo: | The brown stink bug, Euschistus servus (Say), is abundant throughout most of eastern North America and is commonly found feeding on soybean, mullein, beans, tomatoes, peas, cotton, wheat, corn, tobacco and peach. Color change in E. servus from green to reddish-brown was shown to be an indicator of reproductive diapause. Reddish-brown insects lived longer than green individuals, females laid no eggs, and males did not produce pheromone. The high mortality registered for the green colony of E. servus adults was associated with the physiological cost associated with reproduction. The main pheromone component of this species is methyl 2E,4Z-decadienoate, in agreement with previous work. The first generation of this species develops on noncrop hosts and the second generation often migrates to crops where they may then exceed economic damage thresholds. Traps or trap crops baited with pheromone to catch or concentrate females for destruction, or even a pheromone-based disruption of orientation behavior to decrease the mating success, are possible semiochemical techniques to suppress populations of second generation of E. servus.
