Comparing Different Larval Food Sources and Temperature Regimes for the Rearing of Culicoides obsoletus/scoticus Complex Midges, the Predominant Bluetongue, and Schmallenberg Virus Vectors in Northern Europe

Proceedings, 2020
During the last decade, Europe was confronted with the emergence of two Culicoides-borne viruses, bluetongue virus and Schmallenberg virus. Both diseases caused economic losses in cattle, sheep, and goats. Despite their importance, only limited knowledge

Eggs fertility and biological aspects of the life cycle in natural populations of Simulium (Diptera, Simuliidae)

Brazilian Archives of Biology and Technology, 2006
Eggs fertility rate and some biological aspects of the immature forms were studied on six Simulium species from ovipositions collected in natural breeding places located in rural area. The fertility was considerably high.

Inhabiting warm microhabitats and risk-spreading as strategies for survival of a phytophagous insect living in common pastures in the Pyrenees

European Journal of Entomology, 2012
The breakdown of the transhumant grazing system in the Spanish Pyrenees has led to a severe decline in the area of pastures. However, in the high mountain zone there are still large areas of species-rich grasslands.

‘Candidatus Liberibacter Solanacearum’ Is Unlikely to Be Transmitted Spontaneously from Infected Carrot Plants to Citrus Plants by Trioza Erytreae

Insects, 2020
Bacteria belonging to ‘Candidatus Liberibacter spp.’ are associated with various severe diseases in the five continents. The African citrus psyllid Trioza erytreae (Hemiptera: Triozidae) is an efficient vector of citrus huanglongbing-HLB disease, absent ...

Influence of barometric pressure on odor discrimination and oviposition by adult plum curculios (Coleoptera: Curculionidae)

European Journal of Entomology, 2003
We conducted laboratory experiments to elucidate the influence of barometric pressure on odor discrimination and oviposition and feeding behavior of adult female plum curculios, Conotrachelus nenuphar (Herbst).

Enzymatic Basis for the Oxidative Branch of Aromatic Amino Acid Fermentation Leading to p‐cresol Formation

Advanced Science, EarlyView.
In anaerobic bacteria, tyrosine serves as an electron donor in the oxidative Stickland fermentation branch, generating p‐hydroxyphenylacetate, ATP and reduced ferredoxin for decarboxylation into p‐cresol. ABSTRACT The phenolic metabolite p‐cresol is a byproduct of tyrosine fermentation by certain strictly anaerobic bacteria, including the human gut ...

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

Advanced Science, EarlyView.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.
