3.  Insects are the most abundant animals on Earth.
 They can survive every situation and they are updating
themselves according to situations.
 More than 1 million different types of insects have been
identified.
 Some insects eat our crops or food in storage; others can bite
or sting us, our livestock, or our pets. A few insects spread
diseases.
 Certain insects are helpful to us by producing products we
can use (for example, honey), by pollinating our crops, or by
attacking pest insects.

4.  Entomology is the study of insects and their
relationship to humans, Plants, Environment,
and Other organisms.

5. The word "insect" comes from
the Latin word insectum, meaning with a
divided body, because insects appear cut into
three sections.

6.  Insects have a Exoskeleton which is Made of Chitin
 Three-part body Head, Thorax and Abdomen.
 Three pairs of jointed legs
 Compound eyes and some have simple Eyes
 And one pair of Antennae.

7.  Insects have no internal skeleton .
 They rely on their hard outer coating,
exoskeleton.
 which protects their inner organs and
supports their body

8. 1. Kingdom
2. Phyla
3. Class
4. Order
5. Family
6. Genus
7. Species

9.  The highest level is the Kingdom
 The most specific is the species level.
 Organisms are usually classified by the genus
and species.
 This is called a binomial nomenclature.

10.  Kingdom — Animal
 Phylum — Arthropoda (Jointed legs)
 Class — Hexapoda (insects)
 Order — Lepidoptera (butterflies and moths)
 Family — Noctuidue (noctuids)
 Genus — Helicoverpa
 Species — Helicoverpa armigera
(American bollworm)

11.  Orthoptera- which includes the grasshopper
and locust
(straight Wings)
 Hemiptera- which includes the true bugs
such as leaf hoppers and plant bugs

12.  Lepidoptera – moths and Butterflies ( Scale Wings)
 – Homoptera- aphids
(Equal Wings)

13.  Thysanoptera- Thrips
(Tassel Wings)
 Coleoptera- which is the largest group of the
insect orders this has beetles (Sheath Wings)

14.  Head
 Thorax
 Abdomen

15.  Brain but Nerve centers elsewhere in the body
 Has a pair of compound eye and simple eye
 Two sensory appendages called antennae
 And Mouth.

16.  Is divided into three segments from which
 are attached three pairs of legs.
 And Pair of Wings in Adults.

17.  Is attached to the thorax
 which will contain more segments
 Like Execratory System and Reproduction
Organs.

18.  Incomplete Metamorphosis
 Complete Metamorphosis

19.  Eggs
 to Early nymph (no wings)
 to late nymph (wings developing)
 Goes to Adult

20.  The order Orthoptera & Hemiptera encompasses
the more than 80,000 species of true bugs in Class
Insecta.
 Members generally possess two sets of wings, but
some exceptions have reduced wings or no wings at
all.
 Bugs possess mouths designed to puncture and slurp
liquids such as sap.
 After bugs hatch from their eggs, they pass five
nymph stages before entering adulthood.
 Order Hemiptera includes many of the destructive
bugs, such as aphids, known to agriculture

 Pupa to
 Adult
