Dragon-flies v Mosquitoes

Dragon

Objectives: Dragon Systems is developing and building high performance, computationallyefficient interactive speech workstations, to sup'port adaptive speech recognition of large vocabulary, natural language speech input in real-time. These systems are based on the results of the multi-knowledge source (MKS) algorithm architecture and multi-processor accelerator hardware studies previously unde...

Notes on Sand-Flies. Part V

Natural DEET substitutes that are strong olfactory repellents of mosquitoes and flies

Despite shortcomings, N,N-Diethyl-3-methylbenzamide (DEET) has remained the gold-standard of insect repellents for >60 years. There are significant impediments to finding improved substitutes because the molecular targets causing repellency are unclear, new chemistries will require significant human-safety testing, and predicted costs for development are exorbitant. Here we identify shared stru...

Genome Sequence of Brevibacillus laterosporus UNISS 18, a Pathogen of Mosquitoes and Flies

The entomopathogenic properties of Brevibacillus laterosporus UNISS 18 against insects are well documented. Here, we report the whole-genome sequence of this strain, which revealed the presence of several insecticide action-related genes. The deriving genetic information will help to elucidate the mechanisms underlying strain specificity and virulence against diverse target pests.

Dragon surprise

There are now so few areas of natural environment in the world that have not been subject to biological survey or disturbance so the discovery of new species in recent expeditions to some of these regions has been proving remarkable, although large 'new' vertebrates are now increasingly rare. However, a recent analysis of material collected from lizard specimens in the northern Philippines has ...
