Male flesh flies high-speed pursuit of females
Cornell University entomologists have discovered that male flesh flies traveling at very high speed, in sexual pursuit and swiveling their heads like gun turrets can lose sight of a target female, yet they compensate for the loss of vision and still catch up to mate. The study could lead to better military hardware. (2003-11-10)

Scientists unraveling lice genome to halt blood-sucking pest
Research aimed at understanding how lice feed off humans may lead to new methods to control the blood-sucking pest that can transmit fatal diseases.

Fly bites plant, but plants can bite back, Purdue scientists find
The Hessian fly changes wheat growth by injecting poisons into the plants, but a newly discovered resistance gene that can kill the insect may add a new defensive weapon for the grain crop. Using the new gene in combination with other genes is expected to extend resistance time to the most economically damaging insect of wheat by as much as six times. (2003-09-22)

UCR entomologists report bee-dancing brings more food to honeybee colonies
P. Kirk Visscher, professor of entomology at UCR, reports in Nature that under natural foraging conditions the communication of distance and direction in the dance language can increase the food collection of honeybee colonies. The study also confirms that bees use this directional information in locating the food sources advertised in the dance. The study provides insights that may be of use in manipulating foraging behavior of honeybees for pollination of crops. (2002-12-13)

2,000+ brown recluse spiders in a Kansas home inflict no bites in the occupants, UCR study notes
A UC Riverside study shows that where brown recluse spiders are common, people can co-habitate with them and bites are infrequent. The study focused on 2,055 brown recluse spiders collected in a Kansas home of a family of four. Despite the abundance of spiders, no one in the family received bites from the potentially dangerous arachnids. Throughout the United States, however, physicians routinely make brown recluse bite diagnoses when no brown recluses are known to exist in their states. (2002-12-02)
