Limited sex differences in plastic responses suggest evolutionary conservatism of thermal reaction norms: A meta‐analysis in insects

open access: yesEvolution Letters, Volume 6, Issue 6, Page 394-411, December 2022., 2022
Abstract Temperature has a profound effect on the growth and development of ectothermic animals. However, the extent to which ecologically driven selection pressures can adjust thermal plastic responses in growth schedules is not well understood. Comparing temperature‐induced plastic responses between sexes provides a promising but underexploited ...

Terpenes from herbivore‐induced tomato plant volatiles attract Nesidiocoris tenuis (Hemiptera: Miridae), a predator of major tomato pests

open access: yesPest Management Science, Volume 77, Issue 11, Page 5255-5267, November 2021., 2021
The predator Nesidiocoris tenuis preferred volatiles of Tuta absoluta‐infested tomato plants over those of Trialeurodes vaporariorum‐infested plants. The five‐component blend of α‐pinene, α‐phellandrene, 3‐carene, β‐phellandrene and β‐ocimene attracted the predator, and removal of β‐phellandrene from the five‐component blend enhanced the attraction of ...
