Previous years questions with explanations...for all competitive exams. The head has the compound and simple eyes, segmented paired antennae, and mouthparts including mandibles for biting, and the proboscis for drinking nectar. They have two pairs of wings. Last is the abdomen, which for mouthparts female bees ends in a sting. Labrum-epipharynx is a stylet that has a ventral groove, which forms the food canal with the hypopharynx. The labella are interconnected by a membrane called as Dutton’s membrane. She can be recognized by her abdomen, which is usually smooth and elongated, extending well beyond her folded wings. It is also known as upper lip. The sucking action of muscles of cibarium and pharyngeal muscles help in sucking the blood through the food canal. abdomens. Different insects have adapted themselves to different modes of ingestion of food. The number of stylets varies with different insects. The glossa is similar to a long cylinder. It also contains the salivary canal that injects saliva into the blood of the warm-blooded vertebrates. Housefly feeds on any organic matter, exposed food or even an open wound and faecal matter. The mouthparts of cockroach are biting and chewing type. The mouthparts of honeybee are chewing and lapping type. Hypopharynx: It is chitinous, grooved and a rod-like structure found hanging into the preoral cavity. After Michener (1974, fig. Ingesting liquid food by bees is based on mechanism of "viscous dipping" [5]. Solitary, but nest in aggregations in above-ground pre-existing holes, natural or man-made. Due to the sucking action of cibarium muscles and pharyngeal muscles, the nectar is sucked up. The mouthparts of mosquito are modified for piercing the skin of the vertebrates and then sucking their blood. They also permit any activity requiring a pair of grasping instruments. Prestomial teeth break small food particles and some solid is dissolved in the saliva released on the food. The mouthparts of female mosquito are piercing and sucking type. Mandibles are generalized grasping tools used for gathering pollen, handling wax, and grooming. These similar mouthparts are an example of homologous organs. These mouthparts are characterized by stylets which are long and pointed. Labrum lies below the clypeus, below the labrum is a fleshy epipharynx which is an organ of taste. Labrum-epipharynx: This is a compound structure formed by the fusion of labrum and epipharynx. Labellum: The glossae are greatly elongated to form a hairy, flexible tongue. Then bees can use their mandibles to manipulate solid substances. Labrum: The mouth is covered by labrum. The basal segment of labium is called post-mentum. The official common name (approved by the common names committee of the Entomological Society of America) for Apis mellifera is the honey bee. Lacinea is pincer like with two terminal denticles whereas galea is the outer soft hood life structure bearing long chitinous bristles. (c) SEM image of the mouthparts. enable_page_level_ads: true (b) When the honey bee is ready to imbibe liquid food, the galeae and labial palp are brought closely together to form a tube around the glossa, a sucking tube, which is similar to a drinking-straw. (adsbygoogle = window.adsbygoogle || []).push({ Bee Anatomy Honey bees are insects and have five characteristics that are common to most insects. They have three main body parts: head, thorax, abdomen. [CDATA[ Mouthparts of honey bee worker (posterior view). The mouthparts of honeybee are chewing and lapping type.

Significance to Humans: Though some have painful and venomous stings (wasps), many are very important and beneficial pollinators (bumblebees). LbPlp - labial palpus There are 1,300 native species of ground-nesting, twig-nesting and parasitic bees found within Arizona. They cut circular pieces from leaves which are used to line their nests. At the time of feeding, the proboscis which is coiled like a watch spring is straightened up due to high pressure of haemolymph. On apical part of each of the segments there are 16-20 hairs. The mandibles in these flies are useful in slicing the skin and then the blood which is exposed is sponged up. The insect releases it when needed for use, then withdraws and folds it back beneath the head when it is not needed. They appear as tracheae and so they are also known as pseudotracheae. Bumble Bees of North America is the first comprehensive guide to North American bumble bees to be published in more than a century. Light to dark … The following is the structure of each of the mouthpart. Labandeira, C. C. (1997). (a) The mouthparts comprise the galeae, labial palp and the glossa. Haustellum bears a theca underneath it. The mandibles are located on either side of mouth behind labrum. The head bears a pair of large compound eyes, a pair of jointed antennae …
