The species occurs across eastern and central North America, with larvae that feed on loblolly pine cones. Adults have a wingspan of approximately 24 mm. The species is part of a genus whose members are significant pests of pine trees, with some related species targeted for biological control research.
Dioryctria taedivorella
Lesser Loblolly Pine Coneworm Moth, Lesser Loblolly Pineconeworm Moth
Dioryctria taedivorella is a small snout moth in the family Pyralidae, described in 1989 from specimens in the southeastern United States. The species is a specialist feeder on loblolly pine (Pinus taeda), with larvae developing within pine cones. It represents one of approximately 40 North American species in the genus Dioryctria, most of which are conifer cone or shoot feeders.
Rhyssa howdenorum
Rhyssa howdenorum is an ichneumonid wasp that parasitizes Sirex nigricornis, a siricid woodwasp pest of pine trees. It was described by Townes in 1960 and has been studied in central Louisiana pine plantations. The species has a single generation per year, with adults emerging from infested loblolly pine logs between mid-August and early November. It serves as a biological control agent against its host, which damages pine timber.
