In 2015, Oxitec developed GM-diamondback moths which produce non-viable female larvae to control populations able to develop resistance to insecticides. The GM-insects were initially placed in cages for field trials. Earlier, the moth was the first crop pest to evolve resistance to DDT [27] and eventually became resistant to 45 other ...
E. culicivora chooses blood fed females over non-mosquito prey, male mosquitoes and sugar-fed female mosquitoes, which demonstrates their preference of blood. As of 2015, E. culicivora is one of only two spiders that have been experimentally studied and considered a mosquito specialist, the other being Paracyrba wanlessi .
An individual mosquito can be heard across 2–5 cm in distance when sound level rises to 22-25 dB. [7] Male and female mosquitoes can also be distinguished by their wingbeat frequencies, which are 700–800 Hz for males and 400–500 Hz for females. [7] As a result, flight sounds are used to determine flight activity and distinguish sex of groups.
Eggs produced by a female after a romp with a sterile male don't hatch. And female mosquitoes typically mate only once, meaning all her eggs are spoiled, so to speak. Vector experts say the ...

Plant evolution may have played a role in the feeding divergence between male and female mosquitoes. At the time when these two mosquitoes became stuck in tree sap that eventually became amber ...
The screw-worm fly was the first pest successfully eliminated from an area through the sterile insect technique, by the use of an integrated area-wide approach.. The sterile insect technique (SIT) [1] [2] is a method of biological insect control, whereby overwhelming numbers of sterile insects are released into the wild.
These mosquitoes are all male and have been sterilized by the radiation, so the hope is that they will find wild female mates and impregnate them with dead-end sperm, rendering the resulting eggs ...
