We have used the pig, a large natural host animal for influenza with many physiological similarities to humans, to characterize αβ, γδ T cell and antibody (Ab) immune responses to the 2009 pandemic H1N1 virus infection. We evaluated the kinetic of virus infection and…

Sterile insect technique (SIT)-based pest control programs rely on the mass release of sterile insects to reduce the wild target population. In many cases, it is desirable to release only males. Sterile females may cause damage, e.g., disease transmission by mosquitoes or…

Germ-line transformation of a major agricultural pest, the Mexican fruit fly ( Anastrepha ludens Loew, Mexfly), was achieved using composite piggyBac transposable elements marked with green, yellow and red fluorescent proteins (CopGreen, PhiYFP and J-Red). We also…

Cytoplasmic incompatibility (CI) induced by the endosymbiont Wolbachia pipientis causes complex patterns of crossing sterility between populations of the Culex pipiens group of mosquitoes. The molecular basis of the phenotype is yet to be defined. In order to investigate…

Wolbachia are intracellular maternally inherited bacteria that can spread through insect populations and block virus transmission by mosquitoes, providing an important approach to dengue control. To better understand the mechanisms of virus inhibition, we here perform…

The yellow-legged or Asian hornet ( Vespa velutina colour form nigrithorax) was introduced into France from China over a decade ago. Vespa velutina has since spread rapidly across Europe, facilitated by suitable climatic conditions and the ability of a single nest to…

The yellow-legged Asian hornet ( Vespa velutina nigrithorax) is an invasive species that presents a threat to apiculture in Europe; first introduced into France in 2004, it has subsequently spread into neighbouring European countries. There is a risk of invasion and…

BACKGROUND: Small hive beetle (SHB), Aethina tumida is an invasive pest of managed honey bees and has invaded Europe from Africa. The main risk point identified for incursions of this pest into the UK is imports of package bees and queens. Surveillance of this pest, carried…

Vespa velutina nigrithorax is an invasive species of hornet accidentally introduced into Europe in 2004. It feeds on invertebrates, including honey bees, and represents a threat to European apiculture. In 2016, the first nest of this hornet was detected and destroyed on…
