Monitoring of insect pests Etiella behrii, E. zinckenella, Cryptophlebia ombrodelta, Cydia notanthes, Ostrinia furnacalis, Spodoptera litura, and S. exigua was conducted with sex pheromones in vegetable soybean fields in Pintung, Yunlin, and Chiayi, Taiwan during 2010 to 2012. The results showed that the population density of S. litura was higher than S. exigua. The population densities of S. litura from 2010 to 2012 were less than 775 insects/trap/week of the fall vegetable soybean fields at area B of Changzhi, Pingtung in 2011, whereas those of S. exigua were less than 82.5 insects/trap/week in the spring vegetable soybean fields at Wandan, Pingtung in 2011. The population densities of borers were consistently low, with less than 83.5 insects/trap/week of O. furnacalis in the spring vegetable soybean fields at Wandan, Pingtung in 2011, followed by O. furnacalis, C. ombrodelta, E. behrii and E. zinckenella. Because no moths were caught in the traps set at the vegetable soybean fields in Yunlin and Chiayi, the habit of C. notanthes feeding on vegetable soybeans requires further investigation.
