Hemipter information

2. HEMIELYTRA HW-MEMBRANEOUS

6. BASED ON PHYLOGENETIC RELATIONSHIP
Widely distributed and
most economically
important
Distributed only few parts of
World Australia, Newzeland,
America

7. ECONOMICALLY IMPORTANT FAMILIES OF
SUB ORDER: HETEROPTERA

8. SO:- HETEROPTERA
•Forewings hemelytra-basal half is thickened
and the apical half is membranous
• Rostrum arising from anterior part of the head
• Wings held flat over the body
• Stink glands often well developed

9. HEMIELYTRA
Pronotum well developed,
TRIANGULAR/V SHAPED SCUTELLUM

13. ECONOMIC IMPORTANCE:-This Fmily includes larges bugs. These are highly
predacious, feeding on small fish, tadpoles, young frogs, and insects. They can fly
from one water source to another and are often attracted to light. They inflict
painful bites when handled.
Ex. In some species of Belostoma, eggs are laid on back of the male: Belostoma
indica, Lethocerus indicus

16. Head is narrow, elongate and constricted at
the base
Isyndus heros

17. Predacious nature

20. Fertilization:- male having strong spine like ovipositor with that it directly inserts
aedigus in to the ventral surface of abdomen and deposits the eggs in a pouch like
structure (Organ of Ribaga) so this type of reproduction i.e., male will directly
deposits the eggs by wounding the exoskeleton of female body called Traumatic
insemination

21. Pronotum flat with
lateral expansion
Cimex lectularius, Cimex rotundatus

22. Family-. Pentatomidae: -Shield/stink bugs (bad smell emitting bugs)

23. Scutelleridae is a family of true bugs. They are commonly known as jewel bugs or metallic
shield bugs due to their often brilliant coloration. They are also known as shield-backed bugs
due to the
enlargement of the thoracic scutellum into a continuous shield
over the abdomen and wings.
Scutelleridae:- Shield bugs

26. Coreidae Leaf footed bugs
