To Kelli Hoover and David Hughes of Penn State University and their colleagues, the climbing behavior of the caterpillars seemed like an exquisite example of an extended phenotype. By causing their hosts to move up in trees, the baculoviruses increased their chances of infecting a new host down below. To test Dawkins’s idea, they examined the genes in baculoviruses, to see if they could find one that controlled the climbing of caterpillars.

A parasitic fungus that must kill its ant hosts outside their nest to reproduce and transmit their infection, manipulates its victims to die in the vicinity of the colony, ensuring a constant supply of potential new hosts, according to a new study published in PLOS ONE.

An international team of researchers has discovered honey bee colonies in Newfoundland, Canada, that are free of the invasive parasites that affect honey bees elsewhere in the world. The populations offer a unique opportunity to investigate honey bee health, both with and without interfering interactions from parasites.
