Mosquito eats algae from the surface of the water on the stage of Larva. Also perceives humidity changes, variation in temperature, vibration, wind velocity and direction. To find out why, Riffell's team turned to the individual chemicals that make up the blunt-leaf orchid's scent. 2) PROGNATHOUS (Pro- infront ; gnathous - jaw) This type is also called coleopteroid type. The wingspan is generally about 1.0 to 6.5 cm (1 ⁄ 2 to 2 + 1 ⁄ 2 in), though some species of Holorusia can reach 11 cm (4 + 1 ⁄ 4 in). Example : Female mosquito 9 Female mosquito Antenna shape 10. .

"We often describe 'scent' as if it's one thing — like the scent of a flower, or the scent of a person," said Riffell. Other multiporous sensilla such as auricillica (11.90 ± 0.99) and coeloconica (4.57 ± 0.25) were significantly more abundant in female than in male antennae.

The terminal two antennal segments of male Aedes aegypti bear the same variety of sensillar types as the female's antenna, namely, sensilla chaetica, sensilla coeloconica, sensilla ampullacea, grooved pegs, and four types of sensilla trichodea: long and short, pointed-tipped trichodea and blunt-tipped types I and II. Expression of AgOR2 in the antenna of female and male mosquitoes. In addition to it, the difference between male and female anopheles is based on the mode of consumption of food. These flagella are essential for all the male mosquitoes as it helps them with hearing. The segments of flagellum have very thin whorls of hairs . male mosquito. e.g. plumose antennae well. b Female host-seeking behavior at three stages of the gonotrophic cycle as assayed in a uniport olfactometer [] (ANOVA followed by Tukey's HSD, all differences p < 0.05, n = 8-10 per condition). Male mosquito antennae are particularly well-adapted to detect sound as a means of finding mates. According to experts, the mosquitoes are attracted to different things. They have brown to yellow or orange color.

Beyond pollination, mosquitoes are part of the food web, serving as important prey in both winged adult and aquatic larval form for a lot of other wildlife from dragonflies and turtles to bats and birds—including hummingbirds, which rely on small flying insects and spiders as a primary food source. Sensory cells of mechano- and thermoreceptors were present in almost identical numbers in both sexes, as only about 15% of the long fibrillae, abundant as whorls in the male mosquito, are innervated by a single neuron. Mosquito plumose antennae. Mosquito larva: emerges from an egg, then lives in a pond and feeds on local microorganisms. Stylate: Antenna is just three segmented. In males only, the antennal flagellum bears a large number of long hairs and is therefore said to be plumose. Expression of AgOR2 in the antenna of female and male mosquitoes.

Mosquitoes are vectors of pathogens that cause diseases like malaria, dengue fever, yellow fever, chikungunya and Zika. In males only, the antennal flagellum bears a large number of long hairs and is therefore said to be plumose. 1B, Belton 1989).The flagellum vibrates when stimulated by periodic air displacements (the acoustic near-field) such . The Aedes aegypti mosquito shows extreme sexual dimorphism in feeding. Structurally, mosquitoes have two antennae beneath their eyes, each with two segments. All types of sense organs have similar distribution patterns on the five species, but large differences in number occur, which are discussed with regard to the host preference of the mosquitoes. Insect antennae. The mosquito plumose antenna images have been taken through the foldscope , mosquitoes have two antennae beneath their eyes, each with two segments. The mouthparts of mosquito are modified for piercing the skin of the vertebrates and then sucking their blood. It is at right angles to the long axis of the body. Left: picture by M. A.

Johnston's sensory organ at the base of the antenna serves as a movement sound detector in male mosquitoes, sensing antennal vibrations induced by the flight sounds of conspecific females. The antennae of insects other than the mosquito and its relatives probably do not serve a true auditory function. The mosquito larva breathes air through a special tube. Its species include giant centipede, desert centipede and Vietnamese centipede. and regulatory elements in OR genes appear to control OR expression in subsets of ORNs located in certain sensillum types, specific areas of the antenna and distinct olfactory appendages 39-41. AgOR2-expressing cells were visualized by red fluorescence. . The flagellum forms a long unsegmented , terminal hair. Meanwhile, female mosquitoes can live for six to eight weeks under the right conditions, laying eggs roughly every three days. • Proboscis and 6 needles.
