An adult population survey of four species of the noctuid subfamily Plusiinae was conducted in soybean ecosystems of south, south-central, and north-central Louisiana. Sticky traps baited with synthetic sex pheromone (Z)-7-dodecen-1-ol acetate were used as the sampling tools for two growing seasons. The soy bean looper, Pseudoplusia includens (Walker), reached the highest densities of the plusiinecomplex, with four and five generations detected in the southern and central regions of the state. Although Rachiplusia ou (Guenée) were found to contribute considerably to the plusiine population in June, adult densities were quite low during the later summer months. Trichoplusia ni (Hübner) and T. oxygramma (Geyer) seldom attained high numbers at any location.
