Oviposition and survival of the introduced pine sawfly, Diprion similis (Hymenoptera: Diprionidae), on selected conifers in North Carolina.
The suitability of eastern white pine (Pinus strobus), Virginia pine (P. virginiana), shortleaf pine (P. echinata), slash pine (P. elliottii), pitch pine (P. rigida), loblolly pine (P. taeda) and Fraser fir (Abies fraseri) for oviposition by and survival of Diprion similis (Htg.) was evaluated in greenhouse and field studies in North Carolina in 1980. Total oviposition and percentage larval survival were greatest on eastern white pine. Complete development also occurred on Virginia and shortleaf pines. Larvae did not survive past the 2nd instar on slash or loblolly pine. Oviposition did not occur on Fraser fir, but it did on pitch pine.
