Stink bugs (Hemiptera: Pentatomidae) are agricultural pests of increasing significance in the North Central Region of the United States, posing a threat to major crops such as soybean. Biological control can reduce the need for insecticides to manage these pests, but the parasitism of stink bugs byTachinidae (Diptera) is poorly characterized in this region. The objective of this study was to evaluate the rate of parasitism of stink bugs by tachinids over 2 yr from nine states across the North Central Region. Parasitism was assessed by quantifying tachinid eggs on the integument of stink bug adults. Parasitism rates (i.e., percent …

A survey of hymenopteran and dipteran parasitoids of the fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) larvae was conducted to determine their occurrence and parasitism rates in Western Chiapas, Mexico. 1247 FAW larvae were collected from whorl-stage corn cornfields in 21 locations in the region called ‘‘La Frailesca’’ in Chiapas, Mexico during the summer of 2002; 251 larvae produced parasitoids for an overall parasitism rate of 20.1%. Five braconids were recovered from FAW larvae, Rogas vaughani Muesebeck, R. laphygmae Viereck, Chelonus insularis Cresson, C. cautus Cresson, and Glyptapanteles militaris Walsh. Two ichneumonids, Neotheronia sp., and Ophion flavidus Brulle, and one …
