Substrate preferences in adult Pselactus spadix (Herbst)
2000 - IRG/WP 00-10352
Adult preferences of P. spadix were tested in a series of olfactory and tactile choice tests. Tests employed pine and beech wood blocks, which were undecayed or decayed by soft rot fungi, wetted with seawater or freshwater and drilled or undrilled. Survival of individual adults on undecayed pine and beech in a non-choice test was determined. Olfactory cues were found not to be an important factor ...

Behavioural and morphological adaptations to tidal inundation in the adult wood boring weevil Pselactus spadix Herbst
1999 - IRG/WP 99-10308
Pselactus spadix tunnels wood in the mid intertidal to high intertidal zones and is submersed for several hours with each tide. The submergence and subsequent recovery behaviour, together with sub elytral morphology of P. spadix was investigated and compared to a terrestrial wood borer of the same subfamily Euophryum confine. An investigation of adult activity following submersion in seawater show...

The impact of global warming on the UK distribution of house longhorn beetle Hylotrupes bajulus (L)
2001 - IRG/WP 01-10414
This paper reviews the effects of global warming on insect populations and distribution. The affects of global warming on the spread of Hylotrupes is predicted through a review of research related to the influence of temperature on its life-cycle and flight. Records of Hylotrupes distribution were obtained from published surveys, entomologists and museum collections and were plotted for the UK. Th...
