AbstractSeveral parasites were surveyed for their ability to develop to pupation in virus-infected hosts. The tachinid Compsilura concinnata (Meigen), the ichneumonids Campoletis sonorensis (Cameron) and Hyposoter exiguae (Viereck), and the braconid Cotesia marginiventris (Cresson) developed to pupation in the armyworm, Pseudaletia unipuncta (Haworth), infected with either the Hawaiian strain of granulosis virus (HGV) or the hypertrophy strain of nuclear polyhedrosis virus (HNPV). The braconid Chelonus insularis Cresson died after its HGV- or HNPV-infected host P. unipuncta died. On the other hand, the braconid Glyptapanteles militaris (Walsh) died in HNPV-infected P. unipuncta before the host died. Some of these parasites had tissues that were melanized and some were encapsulated by the host. The ichneumonid H. exiguae and the braconids Chelonus insularis and Cotesia marginiventris developed to pupation in HGV-infected Spodoptera exigua (Hübner). In some cases, developmental time of parasites in virus-infected hosts was longer than in control hosts.

Compsilura Concinnata

Nine parasitoids of the moth genus Heterogynis are presented: six species of Hymenoptera from the families Chalcididae, Eulophidae and Ichneumonidae (Agrothereutes hospes (Tschek), Baryscapus endemus (Walker), Brachymeria inermis (Fonscolombe), Diplazon laetatorius (F.), Itoplectis maculator (F.) and Trichomalopsis heterogynidis Graham), and three Diptera, family Tachinidae (Compsilura concinnata (Meigen), Exorista segregata (Rondani) and Phryxe hirta (Bigot)). Two of these species, Trichomalopsis heterogynidis and Phryxe hirta, are oligophagous parasitoids specialized on the genus Heterogynis. We also identified two newly recorded parasitoids of Heterogynis: Brachymeria inermis (Chalcididae) and Diplazon laetatorius (Ichneumonidae).

Microhabitat Preferences

AbstractTethered gypsy moth larvae, Lymantria dispar (L.) (Lepidoptera: Lymantriidae), placed in various tree microhabitats were most heavily parasitized by Compsilura concinnata (Meigen) (Diptera: Tachinidae) near the ground especially on leaves. In laboratory experiments, hosts were parasitized primarily between 6:00 AM and 6:00 PM (E.S.T.), with little parasitism at night. These data suggest that in the field, this tachinid will most efficiently attack young gypsy moth caterpillars, as instars 1 to 3 are the only ones consistently on or near foliage during daylight. C. concinnata females successfully parasitized young hosts, but larval development on 2nd instars was twice as long as that on 4th instars. Thus, only one generation of parasitoids on gypsy moths is likely per year. Results indicate that methods for improving the effectiveness of this parasitoid should emphasize increasing adult numbers early in the season.

GROWTH AND DEVELOPMENT OF COMPSILURA CONCINNATA (MEIGAN) (DIPTERA: TACHINIDAE) PARASITIZING GYPSY MOTH LARVAE FEEDING ON TANNIN DIETS

Compsilura Concinnata

AbstractAll larval instars of Compsilura concinnata (Meigan) (Diptera: Tachinidae) develop in the midgut of the gypsy moth [Lymantria dispar (L.) (Lepidoptera: Lymantriidae)] between the peritrophic membrane and gut wall. Parasitoid larvae placed artificially in the host haemocoel quickly moved to this characteristic position. There was a positive relationship between parasitoid size, as measured by the weight of the puparium, and the potential fecundity of female flies. When C. concinnata parasitized third-instar larval hosts, there were fewer successful multiple emergences, parasitoid larvae took longer to develop, and puparia were significantly smaller than those of parasitoids attacking fifth-instar hosts.Gypsy moth larvae grew more slowly on diets supplemented with 0.5 and 2.5% tannic acid than on non-supplemented diets. Similarly, C. concinnata females were smaller (with associated reduction in fecundity) when emerging from hosts feeding on the tannin diets than when hosts were feeding on control diets. The effect of tannic acid on the parasitoid was indirect and was the result of a reduction in host quality on the tannin diets. Reduction in parasitoid fecundity associated with tritropic interactions (among the host plant, the gypsy moth, and the parasitoid) may provide a possible explanation for the irregular impact of C. concinnata on gypsy moth populations.
