“…In fact, the type series for D. taedae contains both D. merkeli and D. amatella material, which adds to the confusion (Hedlin et al 1980). Dioryctria amatella occurs in the southeastern United States (Neunzig et al 1964;Neunzig 2003), and is sympatric with D. taedae in parts of its range. Although D. amatella is considered the primary pest of longleaf pine, Pinus palustris Miller, it is known to infest most other pines within its range, making the use of larval host as a diagnostic character for species in that region nearly impossible (Hedlin et al 1980;Neunzig 2003).…”

Biology and management of North American cone-feedingDioryctriaspecies

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.

“…(Merkel 1984). Because these species may drastically limit crops of genetically superior seeds in seed orchards, their biology has been studied extensively during the past forty years (Lyons 1957, Zocchi 1961, Neunzig et al 1964, Charles and Roques 1977, Grant et al 1993, Millar et al 2005).…”

Coneworms of the genus Dioryctria Zeller include a number of serious pests of conifer seeds that are notoriously difficult to distinguish as species. We surveyed mitochondrial DNA variation within the abietella species group by sequencing 451 bp of COI and 572 bp of COII genes from 64 individuals of 6 major species in the group. In addition to examining phylogenetic relationships within European members of the group, the study focused on the two most damaging species, D. abietivorella Grote from North America and D. abietella Denis and Schiffermüller from Europe and Asia, which have been considered taxonomically synonymous in the past. In order to detect different levels of divergence, we extensively sampled in seed orchards and natural forests for D. abietella on different hosts. Maximum parsimony and maximum likelihood analyses confirmed the monophyly of the abietella species group and its separation into three clades. The grouping of North American species (Clade A) received strong support in both analyses, whereas relationships between Clade A and the two other European clades were weakly supported. D. simplicella Heinemann could not be unambiguously separated from D. abietella populations. The diverse haplotypes observed in the network analysis conducted with eight populations of polyphagous D. abietella suggested the presence of two distinct lineages in France.

Tip, Shoot, Root, and Regeneration Pests

Tree branches, shoot tips, and fine roots, are high in nutritive value and generally have comparatively lower amounts of defensive compounds than older tissues. These tree tissues are utilized by many different insect pests around the world. In some cases, these pests can cause loss of tissues, deformation, or even tree death. Many of these pests are native to the region in which they typically damage trees, and their damage is often confined to stressed or dying trees. However, sometimes these and other such pests can be non-native or even invasive, and can impact trees in new areas. Several tip, shoot, and root pests—typically coleopterans, heteropterans, and lepidopterans—can affect pines and hardwoods, both established trees and newly planted ones. In some cases, effective management strategies have been determined, while in others we know very little about potential management. This chapter will highlight several case studies from around the world where insect pests have impacted tree tips, roots, shoots, and/or regeneration. The causal agent will be discussed, as will any management strategies. Ultimately, careful monitoring and reporting can help forest managers be prepared for damage from these pests, and proper forest management will help ensure forests are resilient and resistant to insect pest damage.
