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 <i>Dioryctria</i> 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 <i>Dioryctria</i> species. Current research suggests that many species boundaries are in need of further revision. Major gaps in our understanding of <i>Dioryctria</i> ecology impede the development of integrated pest management tactics. For example, host-generated semiochemicals are important in <i>Dioryctria</i> 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 (<i>e.g.</i>, migration), local (<i>e.g.</i>, feeding stimulants), and temporal (<i>e.g.</i>, development thresholds) scales.Digital Object Identifier http://dx.doi.org/10.4039/n10-045 收起
