摘要: When Spalangia endius was exposed to pupal house flies. Musca domestica , at host-parasite ratios of 0.5:1 through 25:1, the percentage parasitism decreased and number parasitized pupae increased as ratio parasites increased. There were significant differences in per adult wasp, progeny produced wasp associated with host parasite. a difference age above 1:5. i.e., more for 1- 2-day-old than 3-day-old pupae. S. offered choice fly or stable fly, Stomoxys calcitrans similar that obtained when wasps.
