Anopheles Mosquito

Anopheles quadrimaculatus, a primary vector of malaria, is a mosquito species within the family Culicidae and order Diptera. Adults are characterized by their distinct resting posture, in which the head, thorax, and abdomen are held in a straight line, projecting at an angle from the surface. They typically measure 4-6 mm, with dark scales forming specific patterns on their wings, which are diagnostic. Larvae lack the prominent siphon found in Culex, resting parallel to the water surface, taking air from a spiracular plate. Pupae are comma-shaped. Oviposition involves individual eggs laid directly on water. The life cycle duration is highly temperature-dependent, usually 10-14 days at 25-270C and high relative humidity.

Anopheles quadrimaculatus females are primarily nocturnal, initiating host-seeking activity at dusk and continuing into the early morning hours. They are anautogenous, necessitating a blood meal for each gonotrophic cycle, with a preference for large mammals, including humans, cattle, and horses. Mating swarms are observed, typically at dusk, over open fields or near breeding sites. They are known for both endophagic (feeding indoors) and exophagic (feeding outdoors) behaviors, exhibiting plasticity based on environmental factors and host availability. Their flight range can extend up to several kilometers from breeding habitats.
