... says Hoebeke. A biological control method using a parasitic nematode has been remarkably effective in other countries in the southern hemisphere where the woodwasp has been accidentally introduced, he says.

UCSD discovery may help extend life of natural pesticide

...p better pesticides and lead to new treatments for parasitic infections that affect close to two billion people worldwide. "Our previous findings with the roundworm C. elegans strongly suggested that specific sugar structures are likely critical for Bt toxin susceptibility," said Joel Griffitts, the first aut...

Researchers find missing genes of ancient organism

...e Archaea containing organisms that are primitive, parasitic and extremophile, or notable for living in the most extreme environments. Surprisingly, Söll's team found that, although the genome of Nanoarchaeum lacks several intact tRNA genes, functional forms of those tRNAs can be made by copying from two dist...

A bacterial genome reveals new targets to combat infectious disease

...Wolbachia pipientis strain within Brugia malayi, a parasitic nematode responsible for lymphatic filariasis. This Wolbachia genome is small, only about a million base pairs, and many metabolically critical genes have degraded through mutation to the point of uselessness. This phenomenon, called reductive evolu...

Researchers reveal the infectious impact of salmon farms on wild salmon

...nal academy of science) shows that the transfer of parasitic sea lice from salmon farms to wild salmon populations is much larger and more extensive than previously believed. This quantitative analysis of parasite transfer is a scientific milestone in a contentious debate. It is the first to isolate and measu...

Ecological destruction fuels emerging diseases

...k the ability to predict and thus prevent emerging parasitic diseases. "Right now, we're just reacting out of ignorance whenever an unfamiliar disease catches us off guard and we call that management," says Dr. Brooks. "We're always behind the curve, because we don't know where these things are coming from." ...

Plants respond similarly to signals from friends, enemies

...trogen for the plant, and root-knot nematodes, the parasitic foes that want to harm the plant. Signals from both outsiders induce rapid changes in distribution of the plant's cytoskeleton, which is part of a pathway that leads to a series of growth changes that include the formation of either nodules housing b...
