    Introduction Biocontrol Insects For Greenhouses Introduction Biocontrol Insects For Greenhouses Presentation Transcript

    • Biological Insect Pest Control for Greenhouses Brooke Edmunds, PhD CSU Extension-Adams County Regional Specialist, Commercial Greenhouses & Nurseries
    • What is Biological Control?
      • The rearing and release of living organisms that seek out and destroy organisms considered to be pests
      • First known use: 324 BC
        • Chinese growers strategically placed ant colonies to control foliar insects in citrus trees
      • Commercial biocontrol started in late 1960’s
      • ~30 species of insects available today
    • Why consider Biocontrol?
      • Pesticide options are limited
        • Herbs & vegetables
        • Insecticide resistance
      • Reduce risk of worker exposure
      • Reduced re-entry times-better scheduling
    • Outline
      • General biocontrol agents
      • Common biocontrol insects used in greenhouses
      • Steps to getting started
    • Lysiphlebus testaceipes Parasitoids
    • Predators
    • Beauveria bassiana Pathogens
    • Heterorhabditis bacteriophora Entomopathogenic Nematodes
    • Parasitoids Predators
    • Today’s Focus:
      • Predators & Parasitoids
      • What’s the difference?
        • Predator: Insect that utilizes other insects as a food source
        • Parasite: Insect that requires another insect to complete it’s life cycle (eggs laid in other insect)
    • Specificity of biocontrols
      • Most biocontrol insects are specific to a pest
    • Whitefly
      • Silverleaf whitefly
        • Predator – none commercially available
        • Parasite
          • Eretmocerus eremicus (wasp)
      • Greenhouse whitefly
        • Predator – none commercially available
        • Parasite
          • Encarsia formosa (wasp)
    • Spider mites -know pest species
      • Predators
        • Neoseiulus californicus (mite)
        • Mesoseiulus longipes ( mite )
        • Galendromus occidentalis (mite)
        • Phytoseiulus persimilis (mite)
      • Parasite
        • None commercially available
    • Aphids -Know pest species
      • Predator
        • Aphidoletes aphidimiza (midge)
      • Parasite
        • Aphidius colemani (wasp)
        • Aphidius ervi (wasp)
    • Thrips
      • Predator
        • Amblyseius cucumeris (mite)
      • Parasite
        • None commercially available
    • Generalists
      • Orius insidiosus (minute pirate bug)
      • Amblyseius swirskiis (predatory mite)
      • Chrysopa carnea (lacewings)
      • Hippodamia convergens (lady beetle)
    • Getting started:
      • Accurate Pest ID
      • Most biocontrols are host-specific!
      • For help with identification:
        • CSU Extension Faculty
        • Adams Co. Greenhouse Plant Diagnostic Lab
        • Internet sources
      • Scouting
      • Scout pest populations before starting:
        • What are your pests?
        • Where are your problems? Hot spots?
        • When do they occur?
      Getting started:
      • Scouting
      • After biocontrol release: Are the biocontrol insects working?
      • Depending on the species released:
        • Use trap/indicator plants over sticky traps
        • Look for aphid mummies
        • Look for shriveled spider mites
        • Look for blacken pupa
      Getting started:
    •  
    • Eggplant in Gerbera crop Photo: Cornell Univ.
      • Scouting
      • After biocontrol release: Are the biocontrol insects working?
      • Depending on the species released:
        • Use trap/indicator plants over sticky traps
        • Look for aphid mummies
        • Look for shriveled spider mites
        • Look for blacken pupa
      Getting started:

        • Look for blacken pupa
      Getting started:
    • Photos: UC Davis
    • Getting started:
      • Educate yourself
      • Know biology/life cycles of pests & biocontrol
        • What is optimum environment for biocontrol?
          • Humidity? Temps?
      • Create resource list & contacts
        • Suppliers, other growers, Extension agent
    • Encarsia formosa
    • Getting started:
      • Start Small
      • Learn the ropes in a single house or with a single crop
      • Long-term crops (i.e. Poinsettia) work better than short-term crops (bedding plants)
    • Getting started:
      • Give biocontrols best chance for success
      • Screen vents to restrict pest entry
      • Inspect new plants/ quarantine
      Screen vents to restrict new pest entry
    • Getting started:
      • Plan Ahead-Compatible Pesticides
      • Compatible pesticides available to treat hot spots?
        • www.koppert.com or www.biobest.de (click on ‘side effects’) have great databases showing the effect of insecticides on biological control performance
        • Results are compiled from research studies so small-scale tests should be done
    • Encarsia formosa (parasitic wasp) Abamectin (Avid insecticide)
    • http://www.biobest.be/ click ‘side effects’ on top menu
    • Getting started:
      • Select a Supplier
      • Is the supplier a member of the Association of Natural Biocontrol Producers?
      • Have other growers you know dealt with the supplier before and been pleased with the service?
      • Does the producer provide information about its products?
      • Do packages arrive quickly (1-3 days), on time and in good condition?
      • Is the supplier a primary producer of the biocontrol insect, or a distributor?
      • Is the producer a firm that has been around for some years, or a small start up company?
    • Local Sources
      • No endorsements implied-FYI only!
      • Hydro Gardens www.hydro-gardens.com (Colorado Springs)
      • M & R Durango www.goodbug.com (Bayfield)
      • Web search will turn up other sources
    • Getting started:
      • Insure quality during & after shipping
      • Shipping & holding temp are important!
      Shaker bottle of predatory mites mixed with vermiculite
    • Getting started
      • Insure quality during & after shipping:
      • Do counts if possible immediate on arrival
      • If you receive a shipment of biological control agents and they are all dead: Call the supplier immediately to file a claim .
      • If the counts are low, let the supplier know before you discard the samples. A rep may want to examine the containers to find out what went wrong and how to remedy the problem. Complain about consistently low counts .
      • If there is a serious problem or you are having difficulty doing the counts, try to find an extension agent or pest manager to help you.
    • Getting started:
      • Know Release Rates & Timing
    • Getting started:
      • Success = Patience & Commitment
      • Biocontrol doesn’t produce instant results
      • Requires intensive management
      • Takes more time
      • Balance between allowing biocontrol time to work and managing an insect outbreak another way
