Phylogeny of the parasitic wasp subfamily Euphorinae (Braconidae) and evolution of its host preferences

open access: yes, 2015
The braconid subfamily Euphorinae is a large, cosmopolitan group of endoparasitoid wasps. The majority of species attack adult hosts, a strategy that is rare among parasitic wasps, but there are also many species that attack nymphs and larval stages ...

Side effects of pesticides used in organic and conventional tomato crops on Dolichogenidea gelechiidivoris, a parasitoid of Tuta absoluta

open access: yesPest Management Science, EarlyView.
This study reveals strong variability in the effects of eight tomato integrated pest management‐compatible pesticides on Dolichogenidea gelechiidivoris, identifying harmful compounds such as spinosad and more selective ones such as sulfur and spiromesifen, depending on the exposure route.

Biological Flora of Britain and Ireland: Cytisus scoparius*

open access: yesJournal of Ecology, EarlyView.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.
