A review paper I have been working on sporadically for a number of years has just been published in Agriculture and Food Security:
The worldwide status of stick insects (Insecta: Phasmida) as pests of agriculture and forestry, with a generalised theory of phasmid outbreaks.
Those of you at the Summer
Phasmid Study Group Meeting this year will have seen a talk (
Phasmids as Pests of Agriculture and Forestry) I gave that touched on the species and conclusions presented here. The slides are below.
