These data are counts of spruce beetles (Dendroctonus rufipennis Kirby), Eastern larch beetles (Dendroctonus simplex LeConte), and dubious checkered beetles (Thanasimus dubius F.) captured in multiple funnel traps in response to four different D. rufipennis pheromone lures, including two novel formulations. The data include results from two separate experiments conducted in Fundy National Park, NB, Canada in 2021 and Memramcook, NB, Canada in 2022.

Amounts (ug/beetle) of known pheromone components produced by male and female spruce beetles (Dendroctonus rufipennis), either alone or paired with the opposite sex, and fed for 0, 24, or 48 hours in recently cut white spruce feeding bolts. The beetles were collected as emerging adults from infested spruce harvested in Nova Scotia.
Pheromone extractions were performed by hindgut dissections into 4:1 pentane:hexane spiked with 5 ng/ul of heptyl acetate (internal standard), and were later quantified by GC-MS.

The recent mountain pine beetle outbreak in western Canada provides an opportunity to study the selection and heritability of tree defenses. We examined terpenoid-based defenses of seedling lodgepole pines which were offspring of mature trees subjected to high levels of mountain pine beetle selective pressure. Seedlings were grown from one of three types of cones: old cones on live trees; young cones on live trees; and cones on trees killed by beetles. Offspring thus represented crosses of non-surviving (NS) x surviving (S), S x S, and NS x NS parents, respectively. Methyl jasmonate was used to induce a defensive reaction in the seedlings. Seed source had a significant effect on levels of ten different terpenes, but not on total terpene concentrations. When the seedlings were grouped by location and treatment type, the seedlings of different cone types could be almost entirely distinguished by terpene profiles.
