“…This was saponified and converted to the dibenzylammonium salt. Three recrystallizations of the salt from a mixture of water and acetonitrile gave optically pure dibenzylammonium (5')-3-hydroxybutanoate (6). Compound 6 was converted to butyl (5)-3-hydroxybutanoate (7).…”

“…After removing the solvent from the eluate, the residue was distilled to give (28,38)-2 (2. (28,3R)-3-Methylpentadecan-2-o1 (2). By the same process as that just mentioned, except for the use of 4.0 g of (2R,38)-4 instead of (28,3R) Acetate of (28,38)-3-methylpentadecan-2-o1 «28,38)-2A».…”

“…Although female pheromone composition and male response to female pheromones appear to be similar between N. lecontei and N. pinetum (Matsumura et al 1979;Kraemer et al 1979Kraemer et al , 1981Kraemer et al , 1984Anderbrant 1993), there could be assortative mating by preferred host. Like many other insects, Neodiprion adults tend to mate on the host plant; thus, changes in host preference could produce non-random mating (e.g., as in Rhagoletis pomonella; Feder et al 1994;Feder 1998;Matsubayashi et al 2010).…”

When gene flow accompanies speciation, recombination can decouple divergently selected loci and loci conferring reproductive isolation. This barrier to sympatric divergence disappears when assortative mating and disruptive selection involve the same "magic" trait. Although magic traits could be widespread, the relative importance of different types of magic traits to speciation remains unclear. Because body size frequently contributes to host adaptation and assortative mating in plant-feeding insects, we evaluated several magic trait predictions for this trait in a pair of sympatricNeodiprionsawfly species adapted to different pine hosts. A large morphological dataset revealed that sawfly adults from populations and species that use thicker-needled pines are consistently larger than those that use thinner needled-pines. Fitness data from recombinant backcross females revealed that egg size is under divergent selection between the preferred pines. Lastly, mating assays revealed strong size-assortative mating within and between species in three different crosses, with the strongest prezygotic isolation between populations that have the greatest interspecific size differences. Together, our data support body size as a magic trait in pine sawflies and possibly many other plant-feeding insects. Our work also demonstrates how intraspecific variation in morphology and ecology can cause geographic variation in the strength of prezygotic isolation.
