Neodiprion swainei, the Swaine jack pine sawfly, is a species of sawfly in the family Diprionidae. [1] It is found east of the Rocky Mountains in Canada from Alberta to Nova Scotia and in the Great Lake states of the United States. [2] [3]
Its primary host is the jack pine. Larvae feed more readily on older growth because current-year foliage contains a chemical deterrent. [2] Other pines that may be defoliated if near an outbreak of this sawfly include red ( Pinus resinosa ), eastern white ( Pinus strobus ), and scotch ( Pinus sylvestris ) pines. [4] Only minor infestations have occurred north of 49° N due to the low survival rate of larvae in the cold fall weather. [2]
