1 You’ll never look at a bug the same.
Insect bad guys! You’ll never look at a bug the same.

2 Anatomy 3 Body parts 3 pairs=6 legs

3 Life Cycle-Insect Metamorphosis
Complete Egg Larva (worms/catepillars) Pupa (relatively dormnant) Adult (flies, beetles, etc.) Incomplete Egg Nymph early-no wings Late-wings developing Adult

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

5 Complete Metamorphosis Video

6 Monarch Butterfly Metamorphosis

7 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)

8 Chewing- Beetles Eat leaves Stems Flowers Fruits Nuts

9 Beetles

10 Chewing- Cutworms Usually attacks stems May eat other plants

11 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.

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

13 Caterpillars

14 Chewing- Grasshoppers
Eat all parts of plants

15 Grasshopper

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

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

18 Aphids

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

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

21 Mealy bug

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

23 Thrips

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

25 White flies

26 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

27 Mites

28 cankerworms

29 Insect mouthparts

30 Incomplete Metamorphosis

31 Complete Metamorphosis
