Study Notes
Entomology and Arthropoda
- Entomology is the branch of biology that focuses on the study of insects.
- Insects are related to other Arthropoda.
Taxonomic Position of Insects
- Insects belong to the phylum Arthropoda.
- Phylum Arthropoda has four subphyla: Trilobita, Chelicerata, Crustacea, and Atelocerata.
- Insects belong to the subphylum Atelocerata and class Insecta or Hexapoda.
Characteristics of Phylum Arthropoda
- Bilaterally symmetrical body.
- Body divided into segments.
- Chitinous exoskeleton.
- Haemocoelic body cavity containing circulating blood.
- Dorsal heart and ventral nerve cord.
- Tracheal system.
- Excretion usually by means of malpighian tubes.
- Sexes are always separate.
Characteristics of Class Insecta
- Tracheate arthropods with body divided into head, thorax, and abdomen.
- Head bears a pair of antennae and mouth parts.
- Thorax carries three pairs of legs and one or two pairs of wings (or without).
- Abdomen is devoid of ambulatory appendages and genital is situated near the posterior end of the body.
Division Endopterygota
- Undergoes complete metamorphosis.
- Wings developed internally.
- Immature stage called larva and pupa are different from adults.
- Consists of nine orders.
- Insects are divided into 16 orders.
