title: [Indirect effect of the larval food of an alternative host (Galleria mellonella L., Lepidoptera, Galleriidae) on the reproduction of an entomophagous insect (Lixophaga distraeae Towns, Dipt. Tachinidae)].
abstract: G. mellonella reared on its natural food, beeswax and pollen, is not suitable for a continuous rearing of L. diatraeae. As a matter of fact, L. diatraeae cannot be maintained for more than 10 generations on G. mellonella because the effect of adverse factors during the larval stage progressively reduces both mating rate and female fertility. But adding vitamin E to the natural larval food of G. mellonella eliminates these reproduction disturbances of the parasite, and L. diatraeae rearing can be continued on this alternative host, the diet of which has been enriched with vitamin E.
