How consistent are the transcriptome changes associated with cold acclimation in two species of the Drosophila virilis group? [PDF]

open access: yes, 2015
This work was financially support by a Marie Curie Initial Training Network grant, “Understanding the evolutionary origin of biological diversity” (ITN-2008–213780 SPECIATION), grants from the Academy of Finland to A.H.

Performance of Leptopilina japonica Novković and Kimura (Hymenoptera: Figitidae) Under Fluctuating Temperature and Humidity

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Temperature is an important factor to determine the activity of insects. We tested the performance of the non‐native larval parasitoid Leptopilina japonica (Hymenoptera: Figitidae) under realistic climatic conditions to improve understanding about its ongoing spread and seasonal abundance.

Biological characteristics of Grapholita molesta (Lepidoptera: Tortricidae) induced to diapause in laboratory. [PDF]

open access: yes, 2014
In southern Brazil, Grapholita molesta (Busck) (Lepidoptera: Tortricidae) uses diapause as survival strategy during the winter (May-August). In our study, we evaluated the effect of diapause on biological characteristics of the species for 4 months in ...

Integrating remote‐sensing and meteorological data to identify key drivers of the potential distribution of a grassland grasshopper

open access: yesEcological Entomology, EarlyView.
An ensemble model achieved excellent accuracy (AUC = 0.973) in predicting the potential distribution of O. decorus asiaticus. Climate (temperature & August precipitation) and vegetation type are the primary drivers defining the species' suitable habitats.

Development of a dynamic population model as a decision support system for Codling Moth (Cydia pomonella L) management [PDF]

open access: yes, 2008
In 2004 RIMpro-Cydia was developed as a dynamic population model that simulates the within-year biology of a local codling moth population. The model is meant to be used by growers and advisors to optimize the control of codling moth populations in ...

Host plant use is driven by microclimate not nutritional quality in a grassland butterfly

open access: yesEcological Entomology, EarlyView.
Small Copper butterflies (Lycaena phlaeas) choose to lay eggs on host plants growing in warmer microclimates, despite lower nitrogen content. Bare ground created by European Moles increases host plant temperatures and weakens the negative relationship between nitrogen content and microclimatic warmth.

The Effect of Heterospecific Song and Anthropogenic Sound on the Development of Life History Traits in a Field Cricket

open access: yesEthology, EarlyView.
We raised fall field crickets in acoustic environments of silence, their own song, traffic noise, or the song of the recently introduced Japanese burrowing cricket and measured development, size, and adult survival. We found that crickets reared with burrowing cricket song developed more quickly than crickets reared in silence.

Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

open access: yesInsect Conservation and Diversity, EarlyView.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

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.
