4. *Insects must be killed when they are actively feeding or moving on the plant.

5. Damage Damage depends on the type of mouthpart
Chewing-tear, chew or grind food
Sucking:
Piercing: punctures plant and suck sap
Rasping: rasps or break surface and suck sap.
Siphoning: have a coiled tube they dip into liquid food such as nectar and draw it in (ex. Butterfly)
Sponging: have two sponge-like structures that collect liquid food and move it into the food canal. (ex. House fly)

6. Chewing- Beetles
Eat leaves
Stems
Flowers
Fruits
Nuts

7. Beetles

8. Chewing- Cutworms
Usually attacks stems
May eat other plants

9. Cutworms:  The larvae or caterpillars of some moths are called cutworms (Agrotis, Amathes, Peridroma, Prodenia spp.) because of the manner in which they cut down young plants as they feed.

10. Chewing- Caterpillars
Larva
Moths
Butterflies
Fuzzy and hair
Eat young leaves and stems
Roll up in leaves, makes leaves curl

11. Caterpillars

12. Chewing- Grasshoppers
Eat all parts of plants

13. Grasshopper

14. Sucking
Puncturing the surface to take out the sap of a plant or other animal.

15. Sucking- Aphids Pierce and suck juices Plant lice
Cause stunted growth, yellow spotted leaves
Sticky substance and black mold
Attracts ants

16. Aphids

17. Sucking- Leaf Bugs Causes plants to look unhealthy
Lose normal color and wilt

18. Sucking- Mealy Bugs Pierce and suck from underside of leaves
Suck in leaf axils
Causes yellow appearance
Sticky secretions

19. Mealy bug

20. Sucking- Thrips Chews and then sucks
Causes plant tissue to become speckled or whitened
Leaf tip withers
Leaf curls and dies

21. Thrips

22. Sucking- Whiteflies Feeds on underside of young leaves
Little flying white specks when plants are shaken

23. White flies

24. Sucking- Mites (Watch Out it isn’t an insect)
Attack underside of leaf
Causes leaves to turn gray to grayish
Severe infestations cause webbing
Insects can be red
