Abstract

Diatraea spp. populations have been managed in some areas of the Cauca Valley, Colombia, by means of inundative releases of Tricho­gramma sp. However, recent field evaluations díd not reveal significant benefits resulting from these liberations. Comparative taxo­nomic studies confirmed that two species were involved: T pretiosum, the species reared and released commercially, and T exiguum, the species obtained fromDiatraea eggs collected in the field. Samples taken from different cr­eas of the country showed that the only spe­cies found parasitizing Diatraea spp. eggs are T exiguum. Additional information about morphological characteristics is given to dif­ferentiate T atopovirilia and T. fuentesi, other species found in Colombia wad recorded in America as parasites of Diatraea spp. eggs. It is suggested that T exiguum should be mass-reared and released in commercial sugar cane fields to manage Diatraea spp. populations.
