SOME EFFECTS OF SUPERPARASITISM BY LIXOPHAGA DIATRAEAE OF SUGARCANE BORER LARVAE IN THE LABORATORY

Abstract: A fly parasite, Lixophaga diatraeae (Townshend), of the sugarcane borer, Diatraea saccharalis (F.), is currently being produced at our laboratory to determine if it can be released periodically in sugarcane fields and control sugarcane borers. This parasite is reared on sugarcane borers in the laboratory. Frequently more than one parasite develops on a single host insect and host insects vary in size. When several parasites entered the same host some did not develop because of competition between them. This pr… Show more

“…In the Cuban strain, two lines were successfully selected for puparial size (lowest and highest length), for eight generations, suggesting that such a selection could be used to improve the efficacy of this parasitoid as a biocontrol agent. Body size was found to be correlated with fitness and fecundity in L. diatraeae (King et al, 1976) and also in other tachinids like E. bryani (Reitz and Adler, 1995) and C. concinnata (Bourchier, 1991). In Cuba, attempts were made to maintain (and even improve) the quality of mass-reared L. diatraeae by modifying the composition of the G. mellonella diet, while taking into account production costs.…”

“…In solitary parasitoids, supernumerary eggs or larvae may be eliminated by the adult female wasp or her progeny. Competitors can be destroyed through several mechanisms, including the destruction of eggs or larvae by female parasitoids, physical combat between larvae on or in the host, or various kinds of physiological suppression (Fisher, 1963; King et al , 1976; King & Bell, 1978). In ectoparasitoids, the latter is not possible, and it is assumed that antagonistic interactions occur among immature stages on the host surface.…”

“…This is similar to the parasitoid Lixophaga diatraeae developing in Diatraea saccharalis, Eucelatoria sp. in H. virescens, and T. bombycis in B. mori when the number of maggots per host increased (King et al, 1976;Kumar et al, 1986;Ziser et al, 1977). The rapid development of the parasitoid may be to avoid the nutritional constraints resulting from reduced RCR and digestion.…”
