Sex Quenches Thirst of Female Beetles


In some insect species, including certain beetles, moths and crickets, the males produce exceptionally large ejaculates that can account for up to 10 percent of their body weight.


They found that thirsty females mated 40 percent more frequently than those with free access to water.


Like sponges, females can absorb the water from seminal fluid through their reproductive tracts. The more water they take in, the less frequently they need to mate, an activity that's physically damaging to the females. (The males have spines on their genitalia that puncture females' reproductive tract during mating.)


By delivering a deluge of water with the sperm that thereby also slakes a female's thirst, a male can help ensure his sperm has more time to fertilize the eggs without competing sperm from future mates.


Female beetles mate to quench their thirst, literally.

Jill McGivering investigates drug piracy and the counterfeit drugs which threaten to jeopardise the fight against malaria.
Mosquito biting
Could drug pirates wreck the world's best hope of combating malaria? A new drug, Artesunate, developed from traditional Chinese medicine is being hailed as the best chance of tackling malaria - which kills millions of people every year in Africa and South East Asia.
But it's being undermined by widespread counterfeiting, particularly by counterfeit drugs containing a small amount of Artesunate which then allow the disease to develop a resistance to the drug. And ironically it's Chinese drug pirates who are believed to be largely responsible.
A WHO health official says there'll be a public Health catastrophe if resistance to Artesunate is allowed to develop. Interpol tell us ethnic Chinese criminal gangs, operating across borders, are largely to blame for the counterfeits.
