Introduction

• Pests are small creatures, organisms that are
  notorious of destroying crops, food, causing
  diseases, and attacking livestock. ...

Damage

• Pest damage is a major limiting factor for global
  food production.
• Animal pests destroy 815 of global wheat,
  rice, maize, potato, soybean, and cotton
  production 

7
Damage

• Crops worth Rs 50,000 crore are lost owing to
  pest and disease attack every year as pesticide
  consumption is low in India, according to a
  study.
• FAO estimates that annually between 20 to 40
  percent of global crop production are lost to
  pests.

Introduction and Definition

• An Insecticide is a substance used to kill
  insects.
• They are toxic to human.
• Insecticides have a wide application in the
  field of medicine, agriculture, and industry.
• Insecticides are classified into two types
• 1. Systemic Insecticides .
• 2. Contact Insecticides.

10
2. Difference systemic and contact Insecticides

• Systemic Insecticides- It can be absorbed by a
  plant and move around in its tissue .
• Result- result is high , long time result .
• Use Systemic Insecticide in monsoon
• Example Imidacloprid

11

• Contact Insecticides only contact with leaves .
  
• Those chemicals which injure the target organism
  by physical contact .
• Result if the rainfall happen then the result is
  low .
• Example Cypermethrine ,Acephate.

12
Classification of Insecticides

• 1.Based on chemical composition.
• 2. Based on the mode of entry of insecticide into
  the body of the insect.
• 3. Based on mode of action .
• 4. Based on toxicity .
• 5 Based on stage specificity

Case study of Fall armyworm

14
Introduction

• Scientific name of fall Armyworm
• -Spodoptera frungiperda
• The fall armyworm is a strong flier, and
  disperses long distances annually during the
  summer months

15

16
1-5 states which are infected by the spread of
fall armyworm.

• 1.Karnataka
• 2.Tamil Nadu
• 3.Telangana
• 4.Andra Pradesh
• 5. West Bengal

18
1. Eggs

• Egg masses are cream grey or whitish in colour
• This mass often contain 100-200 spherical eggs .

19
2. Caterpillar

• Egg hatch into small caterpillar with 3-5 days
• Small caterpillar can also carried to other plant
  by wind
• Small caterpillar may appear greenish.
• Caterpillar mature within 14-22 days .

20
3. Pupae

• Catepillar develops into a reddish brown pupa in
  the soil
• Pupae may also found in maize cob.
• Pupae stage lasts for 8-9 days when it is warm
  but can be long as 20-30 days in colder areas .

21
4. Adult

• Moths are active at night espically during warm
  conditions.
