What is Tergum in insect?

A tergum (Latin for “the back”; plural terga, associated adjective tergal) is the dorsal (‘upper’) portion of an arthropod segment other than the head. The anterior edge is called the ‘base’ and posterior edge is called the ‘apex’ or ‘margin’.

What is the concept of insect physiology?

Insect physiology is the study of how insects live and reproduce. This is a historic area of research that continues today. The study of insect physiology is usually divided into a systems approach. These systems are the same required by all animals.

What is suture in insects?

Any continuous or undivided sclerotized plate of the exoskeleton is known as a sclerite and when two sclerites are contiguous the line of junction or demarcation is commonly known as a suture.

What is external morphology of insects?

Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history.

What is tergum and sternum?

Tergum is the covering each segment of the cockroach on the dorsal side. Sternum: The sternum is the covering of each segment of the cockroach on the ventral side.

What are Tergites and Sternites?

Tergite: It is a sclerite (plates that form exoskeleton) present on dorsal side of an abdominal segment in an arthropod. Sternite: It is a chitinous plate present on the dorsal side of an abdominal segment in an arthropod.

Who is the father of insect physiology?

Wigglesworth is one of the few people who can be credited with creating and advancing some discipline of science. He is the Father of Insect Physiology.

What is the importance of insect physiology?

Knowledge about insect physiology and toxicology helps the pathologist to understand the origins and progression of diseases, and a basic knowledge of evolution is essential for identifying mechanisms underlying differential resistance and susceptibility.

What is Apodeme in insect?

Definition of apodeme : one of the internal ridges or ingrowths from the exoskeleton of most arthropods that support the internal organs, provide points of attachment for the muscles, and constitute the endoskeleton of the animal.

What is filter chamber?

The filter chamber is a complex junction of anterior and posterior extremities of the midgut and Malpighian tubules. The sac-like anterior extremity, or filter chamber proper, comprises two cell types.

What is external morphology?

In general, morphology is the study of the exterior structures of living organisms, as well as their forms and internal structures.

What is the importance of insect morphology?

Insect Morphology is presented for the purpose of instructing those interested in the identification of insects, particularly species with predatory or parasitic behavior. The evolutionary format used is to ease the means by which the various insect structures may be learned.
