Persistence without prosperity at the upper range margin: Elevation, microhabitat buffering and biotic pressure in a range‐expanding spider

open access: yesEcological Entomology, EarlyView.
Anthropogenic linear features facilitate high‐elevation colonization. Parasitoid pressure declines markedly with elevation. Cocoon damage increases despite reduced parasitism at high elevation. Abstract The upper elevational range limits of thermophilic arthropods reflect constraints on population persistence rather than simple presence.

First record of Serangium montazerii (Coleoptera: Coccinellidae): A new exotic predator of Aleurocanthus spiniferus (Hemiptera: Aleyrodidae) in Greece

open access: yesEPPO Bulletin, EarlyView.
Abstract The biodiversity of Greek agroecosystems is constantly changing, with the influx of new species reshaping food webs. The present study contributes to the documentation of Greek fauna by reporting, for the first time, the occurrence of the Asian predatory ladybird Serangium montazerii Fürsch (Coleoptera: Coccinellidae). The species was detected

Egg load dynamics and the risk of egg and time limitation experienced by an aphid parasitoid in the field

open access: yes, 2014
Insect parasitoids and herbivores must balance the risk of egg limitation and time limitation in order to maximize reproductive success. Egg and time limitation are mediated by oviposition and egg maturation rates as well as by starvation risk and other ...

First record of Erthesina fullo (Thunberg, 1783) (Hemiptera: Pentatomidae) in Italy

open access: yesEPPO Bulletin, EarlyView.
Abstract The yellow‐spotted stink bug, Erthesina fullo (Thunberg) (Hemiptera: Pentatomidae), is a highly polyphagous stink bug native to Asia with a well‐documented history of human‐mediated dispersal. In recent years, its invasive range has started to expand into Europe.

Laboratory evaluation of the efficiency of telenomus sp., an egg parasitoid of scotinophora coarctata

open access: yes, 2003
Biological control agents help regulate pest populations below damaging levels. Telenomus sp. is an egg parasitoid of the rice black bug (RBB), Scotinophora coarctata. This study was conducted to evaluate the efficiency of Telenomus sp.

A protracted phenology: Post‐diapause larval development of a threatened butterfly

open access: yesInsect Conservation and Diversity, EarlyView.
Larval survival during diapause was high; hibernaculum webs were mostly located near Succisa pratensis plants, which often retained vital leaves through winter. Post‐diapause developmental time varied strongly depending on exposure to different microclimates, being reduced by litter cover, solar radiation and a higher heat load index.
