Ecological effects of invasive alien insects
The effects caused by different insect invaders are reviewed according to their ecosystem roles, i.e. herbivores, predators, parasites, parasitoids and pollinators; the level of biological organisation at which they occur; and the direct and indirect mechanisms underlying these effects.
An Extreme Case of Plant–Insect Codiversification: Figs and Fig-Pollinating Wasps
Biogeographic analyses indicate that the present-day distribution of fig and pollinator lineages is consistent with a Eurasian origin and subsequent dispersal, rather than with Gondwanan vicariance.
Other Hemiptera Sternorrhyncha (Aleyrodidae, Phylloxeroidea, and Psylloidea) and Hemiptera Auchenorrhyncha.
Apart from aphids and scales, 52 additional Sternorrhyncha hemipteran species alien to Europe have been identifi ed within Aleyrodidae (27 whitefl y species), Phylloxeroidea (9 adelgids, 2
Social parasitism by male-producing reproductive workers in a eusocial insect
It is shown that workers of a eusocial bumble bee (Bombus terrestris) enter unrelated, conspecific colonies in which they then produce adult male offspring, and that such socially parasitic workers reproduce earlier and are significantly more reproductive and aggressive than resident workers that reproduce within their own colonies.
A molecular phylogeny and revised higher‐level classification for the leaf‐mining moth family Gracillariidae and its implications for larval host‐use evolution
An exploratory mapping of larval host‐use traits on the phylogeny shows strong conservation of modes of leaf mining but much higher lability of associations with host plant orders and families, suggesting that host shifts could play a significant role in gracillariid diversification.
Alien Terrestrial Invertebrates of Europe
Unlike other groups of animals and plants, no checklist of alien terrestrial invertebrates was available in any of the European countries until recently. Since 2002, such checklists were successively
Preservation of hymenopteran specimens for subsequent molecular and morphological study
Some guidelines are presented for long‐term preservation of insects for non‐traditional systematic studies such as DNA sequencing and internal anatomical research, and cold‐storage in 70% ethanol with or without subsequent critical point drying or chemical drying using hexamethyldisilazane allow both molecular and morphological study.
Effect of non‐lethal sampling on life‐history traits of the protected moth Graellsia isabelae (Lepidoptera: Saturniidae)
Abstract 1. Non‐lethal genetic surveys in insects usually extract DNA from a leg or a piece of wing. Although preferable to lethal sampling, little is known about the effect of leg/wing non‐lethal
Developing methods for testing host specificity of Phymastichus coffea LaSalle (Hym.: Tetrastichinae), a potential biological control agent of Hypothenemus hampei (Ferrari) (Col.: Scolytidae) in
Assessment of the host range of Phymastichus coffea, an endoparasitoid of coffee berry borer, demonstrated that it can be considered as oligophagous, attacking and developing on other species of the genus of the target borer.
