A Van de Graaff can thus be used to accelerate particles up to reasonably high energies: moving an electron through 1 V gains it an energy of 1 eV, so energies of over 20 MeV are achievable by this method (and more if accelerating nuclei with greater than a single electron charge).
They locate females by listening for the sounds of their wings, which run about 250-500 beats per minute. The mosquitoes join, and the males pass sperm to the females, perpetuating the mosquito life cycle. Once their job is done, male mosquitoes live three to five days. The females tend to mate only once, but live considerably longer, depending on how much warmth and moisture is in their environment.
When the flies come through cracks in your walls or through open doors and windows it's often difficult to get out. They fly toward the light of windows, but when the windows are closed, the flies can't escape.n seven to 14 days, these eggs can complete the life cycle through larva and pupa to adult. When the eggs were laid in or near your house, they often fly around inside to seek food and a place to lay more eggs. The most likely place for house flies to lay eggs inside your home is in your garbage can.
