The stipes has five segmented maxillary palp on its outer side. Many insects take in liquid food. The mouthparts of cockroach are developed to suit its habit of feeding on solid food and as a result it has well developed mandibles. This liquefied food enters pseudotracheae by the capillary action upto the mouth via food channel. The figure below is related with mouth parts of cockroach. Lower lip. And the mosquito thus feeds on the blood of vertebrates. Cardo — basal sclerite that articulates with the head capsule; Stipes — medial sclerite that supports a sensory palp Sugars containing solid foods are scrapped are liquefied with its saliva for sponging. A+ BBB Rating. The mouthparts of mosquito are modified for piercing the skin of the vertebrates and then sucking their blood. A) They are closely pressed against each other and form a food canal.

Phylum Arthropoda: Insect mouthparts (Butterfly, cockroach, housefly, honey bee, Mosquito). The parts are ar-ranged in the or-der of segmenta-tion from anterior to posterior. Coiling results from the elasticity of the cuticle of galea together with the activity of the intrinsic muscles. Dissection of Nervous System 4. Tongue. Labrum-epipharynx is a stylet that has a ventral groove, which forms the food canal with the hypopharynx. The mandibles are located on either side of mouth behind labrum. 1. Every cockroach has a mouth, eyes, brain, colon, heart, antennae, salivary glands, mid-guts, reproductive system, gastric caecea, esophagus, legs, malpighian tubules, and fat bodies.

At the distal end the pre-mentum bears a pair of paraglossae inner to labial palps. We have loaded Previous years questions with explanations...for all competitive exams. Due to the sucking action of cibarium muscles and pharyngeal muscles, the nectar is sucked up. Mouthparts of insects are modified cephalic appendages. The paraglossae and glossae together constitute ligula. Housefly feeds on any organic matter, exposed food or even an open wound and faecal matter.

What are the functions of labrum and labium in the insect mouthparts? These mouthparts help the cockroach to bite and chew on hard stuffs, consume soft stuffs and also lap upon liquids. Only maxillary stylets and mandibular stylets are present in bugs, whereas labrum-epipharynx and hypopharynx along with maxillary stylets and mandibular stylets are also present in mosquitoes. Maxillae — paired appendages with the following parts: . The Labium Each has a certain tool for dealing with certain prey. Homometabolous insects have different types of mouthparts in their larvae and adults. All the other mouthparts like mandibles, first pair of maxillae and hypopharynx are enclosed in the groove of the labium. Immature moths and butterflies have chewing mouthparts. These are triangular shaped structures. The mouthparts of housefly are of sponging type. The proboscis is divisible into rostrum, haustellum and labellum. Hypopharynx divides the proximal part of preoral cavity into a larger anterior cibarium and a posterior salivarium. The mouth part of cockroach shown in the given diagram acts as a/an: 1. The Alimentary System 2. 3. Different insects have adapted themselves to different modes of ingestion of food. It is then retracted between labial palps & galeae. If there is any error, correct it. The mouth parts are attached to the ventral side (underside) of the head portion and surrounds the mouth or the oral cavity which faces down. Haustellum: It is the middle part of the proboscis and the proximal part of labium. Labellum: The glossae are greatly elongated to form a hairy, flexible tongue.
