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

Evolution 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 ...

Emerging wild virus of native grass bioenergy feedstock is well‐established in the Midwestern USA and associated with premature stand senescence

GCB Bioenergy, Volume 14, Issue 4, Page 463-480, April 2022., 2022
Switchgrass (Panicum virgatum) is a native North American prairie grass being developed as a new bioenergy crop. New crops may be attacked by novel or previously unrecognized pathogens. We studied the potential extent of switchgrass crop infection by a recently‐discovered virus species called Switchgrass mosaic virus by surveying mature stands ...

Update of environmental risk assessment conclusions and risk management recommendations of EFSA (2016) on EU teosinte

EFSA Journal, Volume 20, Issue 4, April 2022., 2022
Abstract Teosinte, wild maize relatives originating from Mexico and Central America, emerged as a noxious agricultural weed in France and Spain. In 2016, the European Food Safety Authority (EFSA) issued a technical report that assessed the available scientific information on teosinte for its relevance for the environmental risk assessment (ERA) and ...

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

Pest 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 ...
