Bionic Technology Research Study Based on the Non-smooth Surface Morphology of the Mosquito Mouthparts

Using the stereomicroscope and scanning electron microscope, the mosquito mouthpart was observed. The surface morphology of its six mouth needles shows that the upper jaw and lower jaw in mosquito mouthpart, which present typical non-smooth surface morphology, play a role in piercing skins and they are the main organ to do this. The end of the upper jaw is broad like the shape of knife, and there are 25-30 thin saw teeth inside. The non-smooth morphology model of mosquito mouthpart was put in the rear of the injector model, and the rate of reducing resistance can reach as much as 44.5% through Experience [1].
