1. Life‐history trade‐offs under different larval diets in Drosophila suzukii (Diptera: Drosophilidae)

Author:
Jaramillo, Sandra L.; Mehlferber, Eli; Moore, Patricia J.

Subject:
Drosophila suzukii; adults; blueberries; body size; diet; eggs; fecundity; females; larvae; larval development; life history; males; microorganisms; pests; ripening; Europe
Abstract:
... Most larval drosophilids eat the microorganisms that develop in rotting fruit, a relatively protein‐rich resource. By contrast, the spotted‐wing Drosophila suzukii Matsumara (Diptera: Drosophilidae) uniquely develops in ripening fruit, a protein‐poor, carbohydrate‐rich resource. This shift in larval nutritional niche has led to D. suzukii being a significant agricultural pest in the U.S.A. and Eur ...

Hylobius abietis; Picea abies; adults; egg production; females; forest regeneration; girdling; locomotion; males; plant response; seedlings; Europe
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 ...

Endopiza viteana; Eupoecilia ambiguella; Vitis vinifera; acetates; antennae; aromatic compounds; benzaldehyde; beta-caryophyllene; ecology; electroantennography; essential oils; gas chromatography; headspace analysis; males; mass spectrometry; methyl salicylate; moths; neurons; octenol; pests; reproduction; sex pheromones; smell; vines; Europe
Abstract:
... Olfaction is of major importance for survival and reproduction in moths. Males possess highly specific and sensitive olfactory receptor neurones to detect female sex pheromones. However, the capacity of male moths to respond to host-plant volatiles is relatively neglected and the role that such responses could play in the sensory ecology of moths is still not fully understood. The present study ai ...
