They are dentate along their inner margins and are masticatory in function. The U.S. Department of Agriculture estimates that approximately 36 percent of honey bee hives disappeared in 2007-2008. When a female mosquito sits on the host, it presses the proboscis against the skin. In the honey bee, the labium is elongated to form a tube and tongue, and these insects are classified as having both chewing and lapping mouthparts. This labrum is attached to the clypeus. 2. Hemimetabolous insects have similar type of mouthparts in their larvae and adults. The following is the structure of each of the mouthpart. The mouthparts are cleaned with foreleg tarsi [4]. Prmt - prementum Nectar is a sugar solution produced by flowers containing about 80% water and 20% sugars. mouthparts, by forming a large drop between the proboscis and the mandibles, or by fanning over the cells. The salivary duct opens into salivarium at the base of the hypopharynx. They are useful to make a wound in the skin of the host. Labrum-epipharynx is a stylet that has a ventral groove, which forms the food canal with the hypopharynx. Last is the abdomen, which for mouthparts female bees ends in a sting. It also contains the salivary canal that injects saliva into the blood of the warm-blooded vertebrates. Varroa destructor feeds primarily on honey bee fat body tissue and not hemolymph Samuel D.
