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.
During this stage, the legless larvae grow six legs and a pair of wings before emerging as adults. Full pupation takes approximately four days. During this time, the faint outline of the transforming fly is visible through the pupa case. Following pupation, adult fruit flies are ready to mate in about two days.ife Cycle Fruit Fly. The fruit flyâs life cycle begins when the female lays her eggs on a piece of fermenting fruit or other decaying, sweet organic material. She can lay up to 500 eggs, making it difficult to control the population.
