Resumen:
Trypoxylon (Trypargilum) mexicanum (Hymenoptera: Crabronidae) pertenece al grupo albitarse, el cual incluye a las especies mayores del género. Su distribución nativa abarca América Central, desde México hasta Panamá. En este trabajo se menciona por primera vez para la Hispaniola, Antillas. Es difícil imaginarse una especie conspicua como esta sin haber sido detectada anteriormente por algún naturalista o especialista en himenópteros aculeatos, por lo que considero un arribo reciente a la isla. Esta especie pudo haber llegado a través del comercio con América Central, ya que los nidos, hechos de barro, pueden transportar fácilmente los inmaduros, que emergen posteriormente …

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 …
