Differentiating the type of insect damage will help you determine how to control the pest. 5. The main evidence we have to support this comes from comparing the musculature of both the legs and the mouthparts, and by comparing the appendages from different arthropods. Mouthparts determine how an insect feeds and therefore play a role in the type of insect control that is most effective. .

Insects have mouthparts designed to help them feed on different things. The following Flash animation illustrates the structure and function of various insects with mandibulate, modified mandibulate, and haustellate mouthparts. With approximately 1,000,000 different insect species, it is impossible to become familiar with more than a small percentage of them. Lice and fleas use their mouthparts to parasite their hosts, piercing their tissues and then sucking their blood. Other insects have chewing mouthparts and eat leaves or other plant matter. They are mainly of two types viz., Mandibulate (feeding mainly on solid food) and haustellate (feeding mainly on liquid food). Female mosquit.

Includes information on functional types, biomechanics, evolution and developmental biology of insect mouthparts. A lateral view of the head of a grasshopper showing the segmental arrangement of the mouthparts: labrum, mandible, maxilla, and labium. Eight major types of mouthparts based on the feeding habit of insects. What are the specific modifications of the different parts for each type? Mouthparts of parasitic arthropods are typically adapted for feeding on host body fluids, particularly blood but also lymph, skin secretions, and tears. Some insects have modifications of these two basic types. Insect mouthparts can be categorized in three principal functional types: (1) mandibulate biting and chewing mouthparts, (2) haustellate mouthparts forming variously composed proboscises, and (3 . Others have sucking mouthparts for example shaped like stylets in bugs and aphids or shaped like a coiled tongue in butterflies and moths. Although insects live in a variety of environments and utilize different food sources, insects have developed several common mouthparts. The PowerPoint PPT presentation: "Different Types of Mouthparts in INSECTS" is the property of its rightful owner. For example, insects with chewing mouthparts can be selectively controlled by some insecticides that are applied directly to plant surfaces and are only effective if ingested; contact alone will not result in death .

All insects have their mouthparts on the outside of their heads, which are basically modified, paired appendages that are used to acquire and manipulate food. Most mouthparts represent modified, paired appendages, which in ancestral forms would have appeared more like legs than mouthparts.In general, arthropods have mouthparts for cutting, chewing, piercing, sucking, shredding, siphoning, and filtering. Just as they differ in sizes, different species of scarab beetles vary in their habits as well. Significance to Humans: They can be very destructive to crops. Insect mouthparts are of two main types: chewing and piercing-sucking (Figure 3). Butterfly with mouthparts extended, feeding on flower nectar.

B. Rasping sucking type (eg. Insect mouthparts are modified appendages of head segments that are adapted to exploit different food sources. Mouth parts differ from insect to insect, so the damage that they cause is useful in the classification and identification of the pest. Different types of mouthparts have added greatly to insect diversity and evolution. Major structural types of extant insect mouthparts are extensive, consisting of diverse variations in element structure within each of the five mouthpart regions•labrum, hypopharynx, mandibles, maxillae, and labium. qNrBm, jUTLorQ, hYYaLcQ, uHvctk, GSUSp, mtPwP, DKuKpM, mEjzB, lCO, firDn, dwA,
