2. Performance of D. pini after larval development on P. sylvestris twigs which had either suffered oviposition (OP larvae, left/black) or had non-oviposition (NOP larvae, right/grey). Ivo Beyaert et al. Proc. R. Soc. B 2012;279:101-108 ©2012 by The Royal Society

3. Relative abundance of mRNA transcripts of PsTPS1 and PsTPS2 sesquiterpene (ST) synthases in P. sylvestris twigs after different D. pini OP and larval feeding treatments measured by quantitative real-time PCR.
