Beauveria bassiana; Hylobius abietis; alcohols; amino acids; fatty acid methyl esters; fatty acids; females; gas chromatography-mass spectrometry; insects; lipid composition; males
Abstract:
... In the present study, the lipid composition from male and female Hylobius abietis is analyzed pre‐ and post‐infection with Beauveria bassiana. The compounds are analyzed by gas chromatography‐mass spectrometry. In the lipids of males and females fatty acids, fatty acid methyl esters, alcohols, amino acids and other organic compounds are identified. The lipids of males and females after B. bassiana ...

Abstract:
... The pine weevil [Hylobius abietis (L.); Coleoptera: Curculionidae] has a high economic impact on forest regeneration in Europe. The general biology of the pine weevil has received considerable attention, although there is insufficient knowledge about its diel behaviour and time budget. Therefore, in the present study, the feeding and locomotion behaviour of individual adult weevils on Norway spruc ...

3. Olfactory and visual stimuli used in orientation to conifer seedlings by the pine weevil, Hylobius abietis

Subject:
Hylobius abietis; foraging; searching behavior; host seeking; host plants; conifers; seedlings; odors; synergism; pitfall traps; clearcutting; Sweden
Abstract:
... The influence of noncontact plant cues is investigated on the likelihood that individual conifer seedlings will be found by walking adults of the pine weevil, Hylobius abietis, in the field. Traps with solely odour or solely visual stimuli catch significantly more weevils than stimulus-free traps, and traps with the combination of odour and visual stimuli catch more weevils than traps with odour o ...

4. Sub-lethal responses of the large pine weevil, Hylobius abietis, to the pyrethroid insecticide lambda-cyhalothrin

Subject:
lipid content; antifeeding activity; behavioral resistance; Hylobius abietis; lambda-cyhalothrin; Pinus sylvestris; tree damage; sublethal effects; feeding preferences; Picea sitchensis
Abstract:
... The response of the large pine weevil (Hylobius abietis) to the pesticide lambda-cyhalothrin, a pyrethroid, is investigated. Both behavioural (feeding preferences) and nutritional and physiological (lipid content) responses are recorded. Hylobius abietis shows both a significant avoidance of pesticide-treated food sources and a decrease in lipid content after exposure, but a full recovery after fe ...

chemical composition; volatile compounds; electroantennography; insect attractants; Hylobius abietis; allelochemicals; beta-pinene; alpha-pinene; nutrition; Pinus sylvestris; emissions; chemical constituents of plants
Abstract:
... Attraction of the large pine weevil, Hylobius abietis (L.) (Coleoptera: Curculionidae) to pine logs was enhanced by the presence of weevils already on the logs. We investigated the volatiles emitted by insects feeding on host trees to determine the mechanism of the attraction. Chemical analyses of the collected volatiles showed large amounts of monoterpenes. There were no qualitative differences i ...
