Syllabus

Theory

Unit-I: History of entomology in India; development of various organizations in the field of entomology; Position
of insects in Animal Kingdom; Characteristics of Class-Insecta and link with other related classes of organisms.
Unit-II: Insect morphology; external features of an insect-Head, thorax and abdomen; Insect body wall-its structure
and functions; Insect Head-types of head and its appendages like antenna, compound eye, various types of mouth
parts; Insect Thorax-segmentation, thoracic appendages like insect legs and wings, modifications of legs and wings;
insect abdomen and abdominal appendages like male and female genetalia.
Unit-III: Insect Anatomy; structure and function of digestive, respiratory, circulatory, excretory, nervous,
reproductive and endocrine systems.
Unit-IV: Insect metamorphosis, growth and development, various types of larvae and pupae, diapause.
Unit-V: Insect taxonomy: Definition of taxonomy and need for taxonomic study; ICZN, Binomial and Trinomial
nomenclature, taxonomic hierarchy; insect orders with emphasis on agriculturally important orders with their
families: Orthoptera-(Tettiginidae, Acrididae, Gryllidae, Gryllotalpidae, Tetrigidae); Dictyoptera-(Blattidae,
Mantidae); Odonata-(Agrionidae, Aeshnidae); Isoptera-(Termitidae); Thysanoptera-(Thripidae); Hemiptera-
