Abstract

Pine sawflies in the genus Neodiprion Rohwer are widely distributed across the Northern Hemisphere and are pests of commercially important conifer trees. While sampling for Neodiprion species in eastern North America, two colonies of Neodiprion warreni Ross were discovered in Tennessee feeding on Pinus virginiana Mill. These are the first records of N. warreni in Tennessee and on the host P. virginiana. Here, we use a combination of larval and adult female morphology to confirm species identification. We also discuss two potential explanations for these observations: N. warreni was always present in Tennessee and feeding on P. virginiana but, until now, has gone unreported or these new records are attributable to a recent range expansion and host shift. We also discuss potential economic and evolutionary implications of range expansions and host shifts in plant-feeding insect pest species.

The author order was decided through a handicapping competition of five races at Churchill Downs the weekend of the 2023 Kentucky Derby and Oaks. The result of that competition is as follows: In the Grade 2 Edgewood Stakes Papilio (ANG) finished 4th, six lengths ahead of Preliminary (RDR) who finished 11th; In the Grade 1 Kentucky Oaks Pretty Mischievous (ANG) finished 1st, three lengths ahead of Wet Paint (RDR) who finished 4th; In the Grade 2 Pat Day Mile Stakes Echo Again (RDR) finished 6th beating Kangaroo Court (ANG) by twelve lengths, who finished 11th; In the Grade 2 American Turf Stakes Major Dude (RDR) finished 3rd ahead of Mo Stash (ANG) in 4th by a length; and in the Grade 1 Kentucky Derby Angel of Empire (RDR) finished in 3rd, beating 7th place Tapit Trice (ANG) by seven and three quarter lengths. ANG and RDR wish to thank the equine and human athletes who helped us decide which author was to be listed first. We would also like to thank members of the Linnen lab for help with insect rearing.
