none Allorhogas pyralophagus Marsh is a recently discovered doryctine braconid with potential for field trials against stalk borers infesting both large - and small - stemmed Craminacea. This external gregarious parasite was originally reared from Eoreuma loftini (Dyar) larvae infesting Johnson grass (Sorghum halepense (L) Pers.) and sugar cane (Saccharum officinarum L.) from the states of Sinaloa and Nuevo Leon, Mexico. The parasite is easily reared in the laboratory using a wide range of host larvae (Diatraea spp., E. loftini, Chilo sp. and Tryporyza nivelli (F.)). Hosts are placed in grass stems or paper straws for exposure to ovipositing females, A. pyralophagus has been filed released and recovered from the following hosts infesting sugar cane: E. loftini and D. saccharalis (F.) in Texas (USA). Diatraea spp. in Trinidad (West Indies), D. rufescens in Bolivia and T. nivella in Sumatra, Indonesia.
