Laboratory evaluation of Doryphorophaga doryphorae (Diptera: Tachinidae), a parasite of the Colorado potato beetle (Coleoptera: Chrysomelidae)
Environmental Entomology 12 (2), 390-392
Abstract: Doryphorophaga doryphorae (Riley) is a parasite of the Colorado potato beetle, Leptinotarsa decemlineata (Say). In our tests, male parasites emerged a few days earlier than females, with a 3:1 numerical advantage in the first 3 days. The female parasite is larviparous and the prelarviposition period averaged 7.8 days. The average larviposition period was 21 days, with the longest period being 45 days. On the average, the female parasite larviposited 215 times in her lifetime and at the rate of 10.8 times per day. When hosts were withheld for a few days and then made available to the flies, the rate of parasitism and superparasitism was substantially higher than normal for a brief period. Under laboratory conditions, the female did parasitize 1st-instar CPB larva, although at a lower rate (3 to 11%) than it did the other larval instars.
