male mosquitoes cannot suck our blood .why?
Answers
Answer:
Maxillae of male mosquitoes have the same length as the female maxillae, but male mandibles are considerably shorter, which is perhaps the reason why male fascicle is not able to suck blood through a human or animal skin.
Explanation:
All mosquito imago live by drinking nectar. Nectar provides all the carbohydrates necessary of the mosquito imago to live. However, nectar does not have any protein or lipids.
Mosquito imago don’t need either lipids or protein because they have stopped growing. They need the carbohydrates in nectar because carbohydrates have the free energy necessary for them to move. However, a mosquito imago can live without reproduction using nectar alone. This applies to both males and females.
Mosquito larva grow very rapidly. However, all mosquito larva eat meat that they catch underwater.They eat animals smaller than themselves. The protein and lipids needed for growth are in the meat. The lipids supply most of the energy for larval motion, so the larva don’t need nectar or blood.
The embryo of the mosquito lives in the egg. The embryo doesn’t move significantly, so it doesn’t need carbohydrates.The embryo of the mosquito does grow rapidly. So it needs lipid and protein that it gets from the egg yolk.
So the female mosquito imago needs lipid and protein before she lays and egg. The blood of warm blooded animals contains lipid and protein. So she bites a warm blooded animal before she lays eggs. She essentially turns the blood into egg yolk for the embryo.
The spermatophore does not need lipid or protein because it isn’t growing. So the male doesn’t need blood before it mates. The sperm move around, so they need carbohydrates. However, that is already supplied by the nectar that the male drinks.
