Insects are arthropods with three body regions - head, thorax, and abdomen. They typically have six legs, one pair of antennae, and one or two pairs of wings. Insects exhibit either incomplete or complete metamorphosis, going through nymph, pupa or larva stages before reaching adulthood. There are many orders of insects including beetles, flies, butterflies/moths, true bugs, and more, which can be identified by their physical characteristics and life cycles.
This presentation consists of some important families of order Hymenoptera along with their important identifying characteristics and their importance in agriculture as pest as well as parasitoid.

Orthoptera is an order of insects that comprises the grasshoppers, locusts and crickets, including closely related insects such as the katydids and wetas. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts and close relatives; and Ensifera – crickets and close relatives.
Animals are classified into the animal kingdom. Each kingdom is then further divided into increasingly smaller groups based on similarities. The taxonomists names different levels of groups. The development of insects classification gets further advancement when compared to the earlier classification.
Hymenoptera is the third largest order, Over 150,000 species have been described. Apart from the extent, 2,000 extinct species have also been reported.
it consists of ants, bees, sawflies and wasps
Insect are animals , but unlike many animals , they have no backbone .
They have an outer support system called an exoskeleton rather than the inner support system ( endoskeleton ) characteristic of most large animals .
its all about respiratory system of insects, arrangement and position of spiracles system. Types of different respiratory systems in aquatic insects.

Methods and tools for adaptation appraisal in agriculture and assessing crop ...NAP Events
Presented by: Claudius Caezar Gabinete
3.1 Technical guidance on NAPs
The session will take the participants through the technical guidance for NAPs, including: NAP guidelines, guiding principles for adaptation under the Convention, and subsequent products developed by the LEG such as the sample NAP process. It will further look detailed aspects on undertaking assessments by going through best available methods and tools for assessing for assessing crop production as an example. Countries will further provide practical experiences in applying the guidance in the formulation of their NAPs.
you can find answers to what are insects, evolution, why are they dominant creatures on earth, population size, where they are found, life cycle, how insects see, etc.,
4. Insects Are Arthropods
• Insects are the largest group of
Arthropods
• Jointed appendages (bendable)
• Segmented bodies
• Exoskeleton of Chitin that must
be molted to grow
• Related to spiders, ticks,
scorpions, millipedes, crustaceans
5. MAIN CHARACTERISTICS
• Three body regions
– head, thorax, and abdomen
• One pair antenna (head)
• Six legs or 3 pairs (thorax)
• One-two pairs of wings (thorax)
10. Wings or No Wings
• Most adults have 2
pairs
• Called forewings and
hindwings
• Some insects are
wingless (silverfish,
fleas, some termites
and ants)
11. More on Wings
A network of Veins strengthens wings
MEMBRANEOUS (clear) WINGS
12. Some Wings Are Covered
With Powdery Scales
BUTTERFLIES & MOTHS
13. Wings May Be Modified
• Order Diptera
(flies)
• 2nd pair of wings
modified into
HALTERES
• Used for balance
• Makes flies hard
to catch!
14. Beetle Wings
ELYTRA
• Hard Forewing called
Elytra
• Meet in straight line
down the abdomen

hindwings folded
underneath (flight)
17. Why Can’t I Call All of Them
Bugs?
• EVERY BUG is an
insect, but NOT ALL
INSECTS are bugs!

triangular; called
SCUTELLUM
• Last 3rd of wing CLEAR
