“…Like those of other Dioryctria species (McLeod and Daviault 1963;Ebel 1965;Pasek and Dix 1989), newly laid D. abietivorella eggs are creamy white and turn reddish as development progresses (unpublished data). The dark head capsule of the embryo is discernible through the chorion prior to egg hatch (McLeod and Daviault 1963;Pasek and Dix 1989), which occurs approximately 7 days after oviposition at 25 uC for D. abietivorella (unpublished data) and in 324 days at 27 uC for D. ebeli (Ebel 1965). At 25 uC, with a 16L:8D light cycle, D. abietivorella larvae develop through five (occasionally six) instars within 23 days (Trudel et al 1995).…”

“…Members of the auranticella group are typically univoltine (Neunzig et al 1964;Pasek and Dix 1989). Studies conducted in North Carolina and Ontario report one generation of D. disclusa, with adult flight in early summer in the south (Neunzig et al 1964;Pasek and Dix 1989) and midsummer in the north (Lyons 1957). Dioryctria disclusa overwinter as early-instar larvae in Ontario beneath bark scales of red pine (Lyons 1957) but as late instars in cones in the southern parts of its range (Neunzig et al 1964).…”

Coneworms, Dioryctria Zeller (Lepidoptera: Pyralidae), are destructive pests of conifers across North America, and members of several different species groups present significant pest-management challenges in conifer seed orchards. Dioryctria abietivorella Grote (abietella group) is the most pestiferous Dioryctria species in Canada. Despite this status, control tactics are currently limited to broad-spectrum pesticides that threaten non-target species and may result in pesticide resistance. The development of integrated pest management programs targeting Dioryctria species will benefit from a conceptual framework on which to base future research. To create this structure, we review the systematics, evolutionary ecology, and management of cone-feeding North American Dioryctria species. Current research suggests that many species boundaries are in need of further revision. Major gaps in our understanding of Dioryctria ecology impede the development of integrated pest management tactics. For example, host-generated semiochemicals are important in Dioryctria reproduction, although the uses of these cues in host-finding and host acceptance remain unknown. Future research should identify factors that mediate population distribution at landscape (e.g., migration), local (e.g., feeding stimulants), and temporal (e.g., development thresholds) scales.
