Researchers discover key gene involved in bark beetle pheromone production

...om one tree to another to join other bark beetles, mate and start a new life cycle. But other bark beetles know where to locate mates because they are responding to an "aggregation" pheromone. If this pheromone could be disrupted, the beetles wouldn't be able to organize a "mass attack" to successfully c...

Fungus Effective Against Winged Termites

...ey drop to the ground, shed their wings and find a mate with which to start a new colony that may grow to hundreds of thousands of wood-destroying termites. The researchers' find is significant, according to Raina, because many current control efforts focus on eliminating termite workers in colonies--not...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...or forming small bachelor herds." The search for a mate in this vast wilderness is further complicated by the elephant's reproductive biology. Females breed when they are in estrus--a brief period of ovulation that only occurs every two years and lasts just a few days. "Females in estrus make these very ...

Same-Sex Mating Discovered in a Toxic Fungus

...tococcus neoformans, members of the same "sex" can mate and produce offspring. Infection with the fungus can prove life-threatening in humans, and the findings might improve understanding of the fungal biology that underlies the infectious process, the researchers said. Discovery of the same-sex mating mi...

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

... for example remembering territories and potential mate locations." Bilbo stresses that adults rats who were not infected as pups do not suffer memory impairment as the result of adult infection, and those who were infected are completely normal until they get that second immune system challenge. The rel...

Sexual cooperation: Mating increases longevity in ant queens

...ghout their lifetime, ant queens in social species mate only during a short period early in life and store and use the sperm of their mate for the rest of their lives. Sexual offspring are only produced after several months or years of col...

Ants Genetic Engineering Leads To Species Interdependency

...s, populations have been discovered inwhich queens mate with males of another species to produce geneticallynovel hybrid workers.In a new study, Dr. Sara Helms Cahan and colleagues demonstrate thatboth of the species involved have effectively given up the ability toproduce pure-species workers in favor of...
