1. eColeoptera
Leafe Beetles
25,000 species
Cucumber beatles are key pests of vines crops or cucrbits
Some transmit bacterial wilt blocks
2.Chrysomelidae
Oval Body Shape
Many are bright colored
3.Coleptera: Cerambycidae
Long horned beetles
20000 species
larvae typically in dead or living wood
long antennae
some minor forests pests.
4.Scarabaeidae
Scarabs
20000
Lamellate club antennae
Some Serious pests
-white grub larvae
- Japanese Beetles
5. Family Lampyridae
Lightning bugs, fireflies
2000 species
Produce cool light
Larvae is predaceous
6.
Endoparasitic on Thysanura, Orthoptera, Hemiptera, Homoptera, Diptera, and
Hymenoptera
7.
Scorpion Fly
8. Order Hymenoptera (ant, bee, wasp)
Four Wings, hind wings are smaller

Primarily chewing type mouthparts
- Bees: Labium and maxillae form a tongue like structure
- Ovipositor sometimes modified into a sting (Females only)
9. Hymenoptera
-Many social as well as solitary species
Bees/ants most noticeable, but most species are parasitoids
10.
Hymenoptera are habloid/Diploid
Diploid- Full complement of chromosomes
Haploid- Only chromosomes from the female parent
Males produced from unfertilized eggs
Females come from fertilized eggs
- Mother stores sperm and determines sex
11.
Family Formicidae – The ants
About 9,000 species globally
All are social insects
Colonies can exist for years
What defines an ant colony?
Queen – May be several
Workers, soldiers, all female
Males live just long enough for mating
12. Argentine Ants:
Global Power?
Colony stretches 3700 miles across Europe
California colony covers 560 miles
Japan Super Colony
Are they all one monster colony?
13.
Fire ants
-over the entire southern us
iported probably i the 9’a or ’s
-came from S. America
- Do fire ants bite or sting?
Females bite and sting

14. Forming a new ant colony
-Swarming depends on Warmth/humidity
-Mating occurs in the air
- New queens lose wings and males die
15. Managing Fire Ants
Use a broadcast treatment spring and fall
-Baits (food plus poison)
-Broadcast insecticides
Treat individual mounds
- Baits
- Insecticides
- Insecticides or boiling water drenches
16. Leaf Cutter Ants
Nearly all tropical
Very few animals known to grow their own food
Pieces of leaves are brought into the colony
Fungus is grown on the leaves
Fungus is the ants only known food source
Fungus and ants not known to exist separately
17.
Parasitoids
Predators kill and eat multiple prey
Parasites do not usually kill their hosts
Parasitoids lay eggs in or near the host
- The host is ultimately killed.
18.
Parasitoid wasps
Parasitoid wasps are solitary
They are not aggressive
-The females lay eggs in the host
-Parasitoids specialize in one or a few types of prey.
