Spider venoms are usually toxic when injected into prey, but a new protein discovered in the venom of Australian tarantulas can also kill prey insects that consume the venom orally. The protein is strongly insecticidal to ...

The maneuvers of flying insects are unmatched by even the best pilots, and this might be due to the fact that these critters don't obey the same aerodynamic laws as airplanes, a team of New York University researchers has ...

One of the most successful strategies in pest control is to endow crop plants with genes from the bacterium Bacillus thuringiensis, or Bt for short, which code for proteins that kill pests attempting to eat them.

For the first time, researchers are able to prove that there is an optimal speed for certain insects when they fly. At this speed, they are the most efficient and consume the least amount of energy. Corresponding phenomena ...

The oviposition behaviour of insect pests results in an improved durability of insect resistance in so-called Bt-crops, while promoting the survival of pest insects elsewhere in nature. This is the result of research carried ...
