Abstract

The parasitoid females of Ap < /em>ante/es gal/eriae Wilk. laid its eggs in both
healthy and fungus-infected Gal/eria mel/onella larvae. The percentage of parasitism
and the number of eggs laid per parasitoid female were not affected by the fungus
Beauveria b assiana infection. The highest mortality of the host (G. mel/onel/a) and
the least number of parasitoids (A. gal/eriae) emerged when the host larvae were
infected with B. bassiana immediately atter parasitization. When G. mel/onel/a was
infected by the fungus. this caused mortality of different stages of the parasitold
inside the host, being 45.3, 8.6 and 2.5% for larval. pupal and adult stages,
respectively. Developmental durations were 1.44. 12.50, 1.48 and 4.60 days in
healthy hosts and 1.99, 12.50. 1.85 and 7.00 days in fungus infected ones for eggs,
larvae, prepupae and pupae, respectively. Longevity was 7.48 and 4.21 days, and life
cycle amounted 27.50 and 23.00 days for adult female reared from healthy and
infected hosts. respectively.
