Know the Natural Enemies Predators Parasites Pathogens Biological Control IntroductionWhat is biological control?: The use of living organisms to control pest insects, weeds, or diseases. Typically involves some human activity. What is biological control?What are Natural Enemies?: Natural enemies are living organisms that: Kill pests Decrease pest reproductive potential Compete with pest organisms for use of your plants. What are Natural Enemies?Biological control: How is it Implemented? Use what you have (Conservation). Add what you need (Augmentation). By Whom? Predators Parasites Pathogens Biological controlPredators: Adult and immature stages are often generalists rather than specialists. Kill and consume many prey. Generally larger and faster than prey. 200,000 species! Males, females, immatures, and adults may be predatory. Remove the evidence.

Shetlar Predatory MidgeGood Mite or Bad Mite?: Predatory mite Spider mite Good Mite or Bad Mite?A stinger or ovipositor??? : A stinger or ovipositor??? Parasites: Specialized in choice of host. Develop from eggs laid in or on a host (the original “Alien”). Certain kinds of wasps and flies. Could be up to 1 million species! Smaller than host (stealth pays). Only the female searches for host. Leave a trail. ParasitesOvipositor: OvipositorHornworm parasitoids: Hornworm parasitoids Eggs or Pupae??? Eggs or Pupae? Eggs or Pupae?Dissected parasitoid: Parasitized insect was cut open to show the parasites. Dissected parasitoidTyphiid wasp ectoparasitoid: D.

RebekPathogens: Kill, reduce reproduction, slow growth, shorten life of pest. May take several days to provide control. Usually very specific. Leave a trail. PathogensInsect Pathogens: Fungi, example: Beauvaria bassiana Bacteria, example: Bt.

Parasites: small size, not easily seen by gardeners. - many flies and wasps. Pathogens: cause disease in insect not harmful to other organisms.
