REYES-ROSAS, Marco Antonio; LOERA-GALLARDO, Jesús  e  LOPEZ-ARROYO, José Isabel. Modificación al proceso de producción masiva de los parasitoides Catolaccus grandis y Catolaccus hunteri. Agron. Mesoam [online]. 2010, vol.21, n.1, pp.95-101. ISSN 2215-3608.

Modifications to the process of mass production of parasitoids Catolaccus grandis and Catolaccus hunteri. The present study was conducted to modify the actual mass rearing technology for Catolaccus grandis and Catolaccus hunteri, hymenoptera parasitoids of Anthonomus grandis, the cotton boll weevil, in Tamaulipas, México during 2002. The efficiency of the paper towel to seal the wax hydrocarbon polyolefin molded capsules where the host is confined was determined; and the Chickpea weevil Callosobruchus maculatus effectivity was evaluated as a facticious host to rear both parasitoids. The results indicated that C. grandis y C. hunteri mass reared through C. maculatus as a facticious host was possible, and paper towel was effective in sealing the holes in molded WHPS capsules. This mass rearing of C. grandis y C. hunteri by using C. maculatus may contribute to increase security and easiness in the process, and a significant reduction in costs. Paper towel used to seal holes in molded WHPS capsules reduce costs in 50% per square meter of material, without affecting parasitism and emergence of de C. grandis de C. grandis.
