Expert discusses alternatives to pesticides

A researcher at the University of Arizona has discovered compounds derived from Photorhabdus, an insect pathogenic bacterium, that have antimicrobial and nematicidal properties that can potentially replace chemical pesticides.

Researchers advance effort to manage parasitic roundworms

Roundworms that feed on plants cause approximately $100 billion in annual global crop damage. Now researchers at the University of New Hampshire have made a patent-pending discovery that certain enzymes in roundworms, called ...

Why zombie slugs could be the answer to gardeners' woes

Slugs and snails are the bane of almost every vegetable planting gardener and farmer. Slugs in particular have voracious appetites and are relentless in eating stems, leaves and shoots. No wonder gardeners have sought any ...

Survival mode in a tiny worm's brain

Caenorhabditis elegans, or C. elegans, are tiny worms with tiny brains—their whole bodies are the width of a pencil tip and contain only 302 neurons. These nematodes live out their two-week-long lifespans in rotting vegetation, ...

Survival of soil organisms is a wake-up call for biosecurity

Tiny creatures in soil that attack plants have shown the ability to survive for at least three years stored in dry conditions in a recent AgResearch study, giving new insights into the biosecurity threats posed by passenger ...

Parasitic worms may lead to agricultural stem cell breakthrough

The plant parasitic nematode is an agricultural pest that has no fundamental countermeasures and requires the development of resistant plant varieties or pesticides. This parasitic pest creates a nest called a "gall" on the ...

Exploring the genomic basis of parasitism

The genes that cause parasitism in a group of intestinal worms, responsible for one of most prevalent tropical diseases in the developing world, have been identified by an international team of scientists, led by the University ...
