Coddling Moth evolves resistance to viral control

An interesting story about moth resistance to a commonly used organic pest control, granulovirus. It turns out a change in a single sex-linked gene can radically decrease moth susceptibility to the virus. (The article also does a nice job of explaining moth sex chromosomes, which are reversed from what we as humans think of as “normal”.)

Wasp Genetics suggests origin of Altruism

“Researchers at the University of Illinois have used an innovative approach to reveal the molecular basis of altruistic behavior in wasps. The research team focused on the expression of behavior-related genes in Polistes metricus paper wasps, a species for which little genetic data was available when the study was begun.”

(A different version of the story, focusing on the molecular technology used)

Grubs interrupt sub-surface irrigation systems

You could file this under “adding insult to injury”:

“Research by the NSW Department of Primary Industries has found that a small white grub is responsible for water leaking from sub-surface drip irrigation pipes used by some lucerne growers…experiments using glass observation chambers show that the Whitefringed weevil larvae… bite or chew through the pipe using two dark brown pincers….. The larvae attack the roots of lucerne plants causing significant yield loss and sometimes death of the plant.

  1. It’s the “new and improved” rhinovirus, hardier and more effective than ever! ::bleah:: My sympathies! I’ve had this headache since Friday. Makes explaining Punnett squares sooo much fun.
