Spodoptera exigua, beet armyworm is a major agricultural pest in the USA and in tropical and subtropical areas of the world. It has recently become a problem pest in vegetable production in South Georgia especially in tomato. In 2004 and 2005, an insecticide efficacy trial was conducted to determine proper insecticides and rates to control beet armyworm. In 2005 and 2006, an artificial infestation trial was conducted to determine the effect of beet armyworm on tomato yield. A minimum economic injury level of one beet armyworm larva per 20 tomato plants was determined to prevent economic yield loss in tomato.
