Fungal Ecdysteroid-22-oxidase, a New Tool for Manipulating Ecdysteroid Signaling and Insect Development [PDF]

, 2012
Steroid hormones ecdysteroids regulate varieties of developmental processes in insects. Although the ecdysteroid titer can be increased experimentally with ease, its artificial reduction, although desirable, is very difficult to achieve.

Can Fecal T3 Metabolite Level Fluctuations in European Roe Deer (Capreolus capreolus) Give Insights on Body Condition and Thermal Stress?

Integrative Zoology, EarlyView.
European roe deer fecal samples were assayed to investigate the potential fluctuations of fecal thyroid hormone metabolites (FTMs) in response to environmental (e.g., the temperature, local densities) and individual (e.g., sex, age, body, and nutritional conditions) variables.

Reintroduction of an Endangered Butterfly, the Mottled Duskywing (Erynnis martialis)

Animal Conservation, EarlyView.
We reintroduced Mottled Duskywing (Erynnis martialis), an endangered skipper butterfly, at different life‐stages to restored oak savanna habitat in Ontario, Canada and then performed intensive post‐release monitoring. Our results show that, at one of three sites, a population was established within two years of initiating releases and that pupae and ...

Consecutive earthquakes temporarily restructured the zooplankton community in an Alpine Lake [PDF]

, 2012
Two consecutive earthquakes temporary changed a zooplankton community in a high-mountain Lake Krn (altitude 1383 m a.s.l.). It was dominated by the eurytherm copepod, Cyclops vicious, until 1998, when the first earthquake hit the lake (EMS = 5.6).

Development and Reproduction of Nesidiocoris tenuis Reuter (Heteroptera: Miridae): The Effect of Temperature, Origin and Food

Entomologia Experimentalis et Applicata, EarlyView.
Nymphal development took longer at 25°C than 30°C, and the Greek N. tenuis population developed more slowly than the commercial population. Nymphs clearly preferred E. kuehniella eggs over Artemia sp. cysts when both were offered equally. Egg production increased at 30°C, while female longevity declined.

Molecular Phylogeny and Strain Genotyping of the Bacterial Endosymbiont Wolbachia Associated With Tuta absoluta Populations

Entomologia Experimentalis et Applicata, EarlyView.
This study was designed to understand the association between reproductive endosymbiotic bacteria and wild and laboratory‐reared Tuta absoluta populations. The majority of T. absoluta populations showed Wolbachia presence at varying levels of infection, whereas Arsenophonus, Cardinium, and Spiroplasma were not detected. Wolbachia‐positive T.

Oviposition, life cycle, and parasitoids of the spruce cone maggot, Strobilomyia anthracina (Diptera: Anthomyiidae), in the Alps [PDF]

, 2017
The life cycle of Strobilomyia anthracina (Czerny) which exploits Norway spruce seed cones was investigated in 1992 and 1993 in the Alps at c. 1800 m at Torgnon (Valle d'Aosta, Italy) and Lac de Tseuzier (Valais, Switzerland) by sampling cones at ...

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

Ecological 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.

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

Ecological 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.
