Parasitic wasps switch off the immune systems of fruit flies by draining calcium from the flies' blood cells, a finding that offers new insight into how pathogens break through a host's defenses.
Fruit flies infected with a blood-borne parasite consume alcohol to self-medicate, a behavior that greatly increases their survival rate, an Emory University study finds.
Biologists show that fruit fly larvae can make decisions about feeding that balance risk against benefit
We humans aren't the only creatures drawn by the smell of a good meal. Fruit fly larvae, it turns out, are equally susceptible to food scents, although the odors that attract them may not appeal to us.
Bee larvae develop into workers, in part, because their diet of pollen and honey, called beebread, is rich in plant regulatory molecules called microRNAs, which delay development and keep their ovaries inactive. Xi Chen of ...
Biologists uncover molecular mechanism that regulates animal's ability to sense the rate of temperature change
In classic experiments on frogs, scientists found that the amphibians' urge to escape from dangerously hot water decreased significantly when the water temperature rose very gradually.
New research from North Carolina State University and Reed College shows that when fruit flies are attacked by parasites or bacteria they respond by producing offspring with greater genetic variability. This extra genetic ...
