Forceps size and immune function in the earwig Forficula auricularia L
Females of many species select their mates on the basis of the size or intensity of sexual ornaments, and it has been suggested that these provide reliable signals of a male’s ability to resist parasites and pathogens. European earwigs, Forficula auricularia , are sexually dimorphic in forceps shape and length. Male forceps are used as weapons in male contests for access to females, but recent ...
متن کاملDe Novo Transcriptome Hybrid Assembly and Validation in the European Earwig (Dermaptera, Forficula auricularia)
BACKGROUND The European earwig (Forficula auricularia) is an established system for studies of sexual selection, social interactions and the evolution of parental care. Despite its scientific interest, little knowledge exists about the species at the genomic level, limiting the scope of molecular studies and expression analyses of genes of interest. To overcome these limitations, we sequenced a...
متن کاملSusceptibility of the European earwig, Forficula auricularia, to insecticide residues on apple leaves
The European earwig (Forficula auricularia) is potentially a predator of a number of insect pests in apple orchards. However, its effectiveness as a natural enemy in apple orchards may be compromised by insecticide sprays. A laboratory bioassay of eight insecticides currently used in Integrated Fruit Production (IFP) apple orchards and one as-yet unregistered product was undertaken to determine...
متن کاملpathogenecity of entomopathogenic nematode, heterorhabditis bacteriophora poinar, 1975 on the indigenous population of common earwig, forficula auricularia l.
in order to assay the pathogenicity of the entomopathogenic nematode, heterorhabditis bacteriophora poinar, 1975 on the indigenous population of common earwig, forficula auricularia l., several concentrations including 100, 250, 500, 1000, 1500, 2000 and 3000 (ijs/ml of dw) were used in the laboratory conditions. in this experiment, effects of time (f 1, 91= 4.22, p
متن کاملAsymmetric forceps increase fighting success among males of similar size in the maritime earwig.
Extreme asymmetric morphologies are hypothesized to serve an adaptive function that counteracts sexual selection for symmetry. However direct tests of function for asymmetries are lacking, particularly in the context of animal weapons. The weapon of the maritime earwig, Anisolabis maritima, exhibits sizeable variation in the extent of directional asymmetry within and across body sizes, making i...
