Mandibulate Mouthparts In all “primitive” insects, the mouthparts are adapted for grinding, chewing, pinching, or crushing bits of solid food. These are known as “mandibulate” mouthparts because they feature prominent chewing mandibles.

What are insects chewing jaws called?
Insect mandibles are a pair of appendages near the insect's mouth, and the most anterior of the three pairs of oral appendages (the labrum is more anterior, but is a single fused structure). Their function is typically to grasp, crush, or cut the insect's food, or to defend against predators or rivals.
What kind of mouthparts do insects have?
Insect mouthparts are of two main types: chewing and piercing-sucking (Figure 3). Some insects have modifications of these two basic types. Mouthparts determine how an insect feeds and therefore play a role in the type of insect control that is most effective.
What is a jaw like structure called pincer?
Chelicerae are chelate appendages that are used to grasp food. For example, in horseshoe crabs, they are like pincers, whereas in spiders, they are hollow and contain (or are connected to) venom glands and are used to inject venom to disable prey prior to feeding.
What are the four types of insect mouthparts?
If you have access to dissecting microscopes, allow them to look at each insect under the microscope. Explain that there are four types of mouthparts: chewing, (which is the most basic), sponging, siphoning (or sucking), and piercing-sucking.
What's the meaning of mandibles?
1a : jaw sense 1a especially : a lower jaw consisting of a single bone or of completely fused bones. b : the lower jaw with its investing soft parts. c : either the upper or lower segment of the bill of a bird.
What is insect Maxillae?
In arthropods, the maxillae (singular maxilla) are paired structures present on the head as mouthparts in members of the clade Mandibulata, used for tasting and manipulating food.
Why do insects have different mouthparts?
As insects evolved to feed on a wider variety of food resources, their mouthparts adapted accordingly through natural selection. In some cases, an individual component of the mouthparts became specialized for a new function. In weevils, for example, the front of the head is elongated into a long, slender proboscis.
What are insect mouthparts used for?
Typically the mandibles are the largest and most robust mouthparts of a chewing insect, and it uses them to masticate (cut, tear, crush, chew) food items.
Which insect has biting and chewing type of mouthparts?
BITING & CHEWING TYPE or MANDIBULATE TYPE
This type of mouth parts are found in cockroaches, grasshoppers, locusts, termites, wasps, book and bird lice, earwigs, dragonflies and other large number of insects. On the dorsal side there is an upper lip called labrum, which is attached to the base with the clypeus of face.
What type of mouthparts do house flies have?
The mouthparts are of sponging type and are used for sucking liquid food.
What is the name of mosquito mouth?
Proboscis: In female mosquitoes, this mouth part pierces the skin of a person or animal and sucks out blood. The male's proboscis is not strong enough to pierce the skin, and males do not feed on blood. Both female and male mosquitoes use the proboscis to feed on flower nectar and fruit juices.
What is lapping in insects?
Chewing-Lapping Type
In this adaptation, the mandibles and maxillae have shrunk, and the labium has developed into a long tongue called the glossa. The glossa is dipped into liquids and then brought to the mouth in a lapping motion. These insects can drink nectar and other liquid food while biting and chewing.
What are Solenophages?
Noun. solenophage (plural solenophages) (biology) Any solenophagous (feeding directly on blood vessels) organism.
Is mandible a pair?
pair of chewing jaws (mandibles), a pair of complex first maxillae, and a pair of similar second maxillae joined together behind the mouth to form a structure called the labium. Each of the first and second maxillae bears a jointed sensory appendage, or palpus.
What is the upper jaw called?
The upper jaw holds the top teeth in place and supports muscles involved in chewing and facial expressions. It is a major bone in the face. Also called maxilla.
