Question

The mouth parts of Anopheles are adapted to

• A. Biting and chewing type feeding
• B. Piercing and sucking type feeding
• C. Chewing type feeding
• D. Sucking type feeding

Answer 1

The correct option is B Piercing and sucking type feeding

Female mosquito have mouthparts that pierce food items to enable sucking of internal fluids. In female mosquitoes, all mouthparts are elongated. The labium encloses all other mouthparts like a sheath. The labrum forms the main feeding tube, through which blood is sucked. Paired mandibles and maxillae are present, together forming the stylet, which is used to pierce an animal's skin. During piercing, the labium remains outside the food item's skin, folding away from the stylet. Saliva containing anticoagulants, is injected into the food item and blood sucked out, each through different tubes.

So, the correct option is B. ( Piercing and Sucking type )
