Adults and immatures of Diaphorina teucrii sp. nov. (Hemiptera, Liviidae, Euphyllurinae) and adults of Tamarixia dorchinae sp. nov. (Hymenoptera, Eulophidae, Tetrastichinae) from Israel are described, diagnosed and illustrated. D. teucrii sp. nov. develops on Teucrium capitatum (Lamiaceae), representing a family which was previously not recorded as a psyllid host from Israel, and is parasitised...

The phenology of parasitism of the cereal leaf beetle, Oulema melanopus (L.) (Coleoptera: Chrysomelidae) by Tetrastichus julis (Walker) (Hymenoptera: Eulophidae) was studied in small grain fields from 2000 to 2005 in northern Utah, after release and redistribution of the partially bivoltine larval parasitoid during the 1990s. Host larvae first occurred in May, with peak infestation typically oc...

BACKGROUND AND AIMS In the last decade, genomic studies using DNA markers have strongly influenced the current phylogeny of angiosperms. Genome size and ploidy level have contributed to this discussion, being considered important characters in biosystematics, ecology and population biology. Despite the recent increase in studies related to genome size evolution and polyploidy incidence, only a ...

We would like to point out an incorrect statement crediting our previous work in the recent paper of Siripong and colleagues (2006). The authors claim that ‘Recent work has suggested that the data-analysis tools used to assess melting profiles on gel-based microarrays can result in poor-quality melting profiles (Pozhitkov et al., 2005), but work by our group (e.g. Urakawa et al., 2002; 2003; El...

We consider standard and extended CMV matrices with small quasi-periodic Verblunsky coefficients show that on their essential spectrum, all spectral measures are purely absolutely continuous. This answers a question of Barry Simon from 2005.

In 1996, Scirtothrips perseae Nakahara (Thysanoptera: Thripidae) invaded California avocado orchards and moved pest management practices that relied almost exclusively on biological control to strategies dependent on insecticides to maintain thrips densities below economically damaging levels. By 1998, average losses due to thrips feeding damage in untreated infested groves reduced industry rev...

AUCS/TR9405 Building Agent-Based Systems Ciara Byrne and Peter Edwards Department of Computing Science University of Aberdeen King's College ABERDEEN, AB9 2UE, Scotland, UK. Abstract One major focus of e ort in Distributed Arti cial Intelligence (DAI) research has been the development of software environments which support the construction of systems involving multiple interacting agents. Such ...

A new marine gastrotrich species of the genus Cephalodasys is described from shallow sublittoral coralline sand sampled between Lee Stocking Island and Norman's Pond Cay (Exuma Cays), Bahamas. Cephalodasys interinsularis n. sp. reaches a body length of 471 µm and is characterized by a new combination of characters including six total anterior adhesive tubes and five pairs of ventrolateral adhes...

From 22–24 September 2010 the Second Meeting of the Federation of European Societies of Neuropsychology was held at the Royal Tropical Institute in Amsterdam, The Netherlands. The aim of the conference was to provide a meeting place for neuropsychologists, clinicians as well as researchers, from all over Europe. About 450 participants from 17 European countries gathered to present their researc...
