[ Method] In the growth season of to- bacco plants, moth trapper, new moth trapper lure/insect inlet are set up at four different heights （70, 110, 150 and 190 cm vertically from soil surface in the field）, to investigate the quantity of trapped moths. [ Result ] For both trappers, the height of trapping the most moths is 70 - 150 cm, so the initial height of lure/ insect inlet should be 120 cm, considering the 1-m mature tobacco plant height and the 20-cm distance between lure/insect inlet and crop canopy. [ Conclusion] Mother trapper is cheaper, and the new moth trapper is convenient and requires less management cost. The former is favorable for trapping S. litura, and the latter for H. assulta, H. armigera Hubner, and both of them are suitable for trapping A. ypsilon. In tobacco producing regions of Yunnan, population bases of the four noctuids endangering tobacco leaves show the sequence of S. litura 〉 A. ypsilon 〉 H. armigera Hubner 〉 H. assuha. But in tobacco production, H. armigera Hubner, H. assuha, and A. ypsilon cause the most serious damages, so the four noctuids must be controlled.
