none The braconid Perilitus coccinellae (Schrank), generally regarded as a parasitoid of adult coccinellids, oriented toward and inserted its ovipositor (stung) into all four larval stages and pupae of Coleomegilla maculata (DeGeer). Pupae and fourth instars elicited more responses from female parasitoids than the early larval stages. P. coccinellae successfully parasitized all immature stages, except the first instar. However, there was a direct relationship between the rate of successful parasitization and the maturity (stage) of the host at the time of attack. The egg-larva development time of P. coccinellae was inversely related to the stage of the host attacked. Development ( plus or minus SE) averaged 17.1 plus or minus 0.4 days when an adult was parasitized and 25.0 plus or minus 3.2 days when a second instar was stung. Rather than solely a parasitoid of adult coccinellids, P. coccinellae may be classified as a "larval/pupal/adult-adult" parasitoid.
