The development of insect mouthparts from the primitive chewing mouthparts of a grasshopper in the centre (A), to the lapping type (B) of a bee, the siphoning type (C) of a butterfly and the sucking type (D) of a female mosquito. Legend: a, antennae; c, compound eye; lb, labium; lr, labrum; md, mandibles; mx, maxillae; hp hypopharynx.
When mosquito bites, maxillae penetrate the skin and anchor the mouthparts, thus allowing other parts to be inserted. The sheath-like labium slides back, and the remaining mouthparts pass through its tip and into the tissue. Then, through the hypopharynx, the mosquito injects saliva, which contains anticoagulants to stop the blood from clotting ...
Insect mandibles are a pair of appendages near the insect's mouth, and the most anterior of the three pairs of oral appendages (the labrum is more anterior, but is a single fused structure). Their function is typically to grasp, crush, or cut the insect's food, or to defend against predators or rivals.
A siphon is a tubular organ of the respiratory system of some insects that spend a significant amount of their time underwater, that serves as a breathing tube. The larvae of several kinds of insects, including mosquitoes , tabanid flies , and Belostomatidae , live in the water and breathe through a siphon.
(A) grasshopper, (B) honey bee, (C) butterfly (D) mosquito. Bembix rostrata female using its labrum in sucking the blood out of a fly. The labrum is a flap-like structure that lies immediately in front of the mouth in almost all extant Euarthropoda. The most conspicuous exceptions are the Pycnogonida, which are probably chelicerates.
The delicate anatomy of the two mosquitoes was beautifully preserved in the fossils. Both displayed exceptionally sharp and triangle-shaped jaw anatomy and an elongated structure with tooth-like ...
For a mosquito to transmit disease, there must be favorable seasonal conditions, [73] primarily humidity, temperature, and precipitation. [74] El Niño affects the location and number of outbreaks in East Africa, Latin America, Southeast Asia and India. Climate change impacts the seasonal factors and in turn the dispersal of mosquitoes.
