This page describes and illustrates just a small sampling of this diversity. * Tongue like flexible lobe among mouth parts is – hypopharynx. They surround the mouth and are external to it, unlike the condition in vertebrates in which the teeth are within the oral cavity. Pronotum: this sclerite is undivided and Saddle shaped in grass hopper, Shield like in cockroach. It has very thin (membranous) cuticle and contains the opening of the salivary gland duct. Cockroaches are somewhat generalized insects without special adaptations like the sucking mouthparts of aphids and other true bugs; they have chewing mouthparts and are likely among the most primitive of living neopteran insects. *Anterior chamber of preoral cavity is –cebarium. Mouthparts of insects vary to a great extend among insects of different groups depending upon their feeding habits. Most species of cockroach are about the size of a thumbnail, but several species are bigger. Mandibles, maxillae and hypo pharynx are modified to form needle-like stylets which are placed in the labial groove. These structures appear C- shaped in transverse section having a groove, called food channel. 2. * Number of legs in cockroach–6. Cockroach & grasshopper. and Cranston, P.S., 1994) • the hypopharynx , an unpaired, tongue-like 1). The basic segmental character of the mouthparts is most apparent in insects that bite off fragments of food and then chew it before ingesting it (Fig. Cd - cardo (plural cardines) Ga - galea Gls - glossa (tongue) Lbl - labellum LbPlp - labial palpus They are common and hardy insects, and can tolerate a wide range of environments from Arctic cold to tropical heat. The sucking pump creates the negative pressure necessary to draw the food into the mouth. 27. Hidden among the maxillae and labium is the “tongue” or hypopharynx. Cockroach, (order Blattodea), also called roach, any of about 4,600 species of insects that are among the most primitive living winged insects, appearing today much like they do in fossils that are more than 320 million years old. These are the shortest legs, and they act like brakes when the roach runs. It is the primitive type of mouth part and consists of the following parts. They are mainly of two types viz., Mandibulate (feeding mainly on solid food) and haustellate (feeding mainly on liquid food). In North America and Europe, it is confined almost exclusively to indoor environments of heated structures. Structure and Function 13 Fig. The mouthparts are unfolded and spread apart. Cockroaches are somewhat generalized insects without special adaptations like the sucking mouthparts of Hemiptera; ... such as the gregarious German cockroach, have an elaborate social structure involving common shelter, social dependence, information transfer and kin recognition. Cockroaches are somewhat generalized insects without special adaptations like the sucking mouthparts of aphids and other true bugs; they have chewing mouthparts and are likely among the most primitive of living Neopteran insects. Most of the time they are folded behind the head and held together. * Number of podomers–5. They are common and hardy insects, and can tolerate a wide range of environments from Arctic cold to tropical heat. Mandibles - A pair of hard, horny, heavy, large, with jagged inner edges and dark coloured triangular structures found one on either side. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. The cockroach mouthparts consisting of a labrum (upper lip), a pair of mandibles, a pair of maxillae and a labium (lower lip). 2-6: Components of the mouthparts of an earwig (Dermaptera). (8) Mouthparts of cockroaches are mandibulate type or cutting and chewing type. After Michener (1974, fig.
