Neodiprion is a Holarctic genus of conifer-feeding sawflies (Order: Hymenoptera; Family: Diprionidae) with an intimate and life-long association with their hosts: eggs are embedded within the host tissue, larvae spend their entire feeding period on the natal host, cocoons are spun either on the host or directly beneath it, and adults mate on the host plant. This tight association is accompanied by specialized feeding habits and all Neodiprion species (~50 described to date) are restricted to host-plants in the family Pinaceae, with most species found exclusively on host plants in the genus Pinus. Among species that are restricted to pines, host range varies from strict monophagy (only a single host species is utilized) to comparatively more polyphagous feeding habits (multiple pine species are utilized).
Because many members of the genus are economically important forestry pests, the life histories of many Neodiprion species have been studied in great detail. This wealth of data is especially pronounced for the lecontei species group, a monophyletic clade of ~20 species distributed throughout eastern North America, many of which have been the subject of entomological, forestry, and evolutionary research spanning the last 70 years. In addition to being well studied, Neodiprion are abundant in nature, can be reared and crossed under laboratory conditions, and vary in many ecologically important traits (e.g., host range, larval color, larval gregariousness, and overwintering mode). Together, these features make Neodiprion an excellent model system for uncovering the molecular mechanisms and evolutionary processes that generate and maintain variation in nature.
The Neodiprion lecontei (redheaded pine sawfly) genome, which consists of 7 chromosomes and 330 MB, is the first of 20 planned genomes for the lecontei species group.
Data use policy: Data for the Neodiprion lecontei genome are provided pre-publication and are covered by the Ft. Lauderdale and Toronto agreements. Following these agreements, the data producers make the data available and state their intent to publish analyses, the data users ask permission to use the prepublication data and cite the appropriate source, and the journals and reviewers ensure that articles are published following the guidelines. Please contact the genome community contact if you wish to use these data in published analyses.
