Integrated Pest Management
2
PEST MANAGEMENT Cultural (Prevention) Modification of normal plant care Proper plant selection Resistant species Proper watering, fertilizing, etc.
3
PEST MANAGEMENT Mechanical Labor, materials (not pesticide), machinery Picking bagworms (labor) Removing debris (labor) Mulching (material) Mowing (machine)
4
PEST MANAGEMENT Physical control Environmental manipulations Light, temperature, humidity, and moisture Use of straw to reduce frost damage Pruning to increase air movement and light penetration
5
PEST MANAGEMENT
16
Does nothing.
17
PEST MANAGEMENT Biological (Beneficial organisms) Plant diversity increases beneficial presence Overuse of chemicals reduce beneficial presence Release

Integrated Pest Management IPM – ecological approach to preventing unacceptable pest presence or damage < 0.1 % of all insects are harmful to plants Moderate levels of a pest can be harmless, even beneficial when providing food for predators
30
COMPONENTS OF AN IPM Prevention Plants weakened by improper selection, planting, and management
31
COMPONENTS OF AN IPM Identification Which pest is causing the damage? Are symptoms abiotic? The wrong ID could result in the wrong treatment
42
COMPONENTS OF AN IPM Monitoring/Scouting Different monitoring programs for each pests Scouting routines weekly Know common problems in area and time of occurrence -When and What to look for
43
COMPONENTS OF AN IPM Monitoring/Scouting Scouting for pest and/or symptoms Know beneficials and damaging insects
44
COMPONENTS OF AN IPM Thresholds Every plant tolerates certain amount of pests and damage When should action be taken?
45
COMPONENTS OF AN IPM Agricultural thresholds Yield determine threshold 2 hornworms per tomato significantly reduces number of tomatoes produced Most research has been applied in this area http://ipmpipe.org/ http://ipmpipe.org/
46
COMPONENTS OF AN IPM Ornamental thresholds When does damage look bad? Client’s expectations Little research done in this area
47
COMPONENTS OF AN IPM Thresholds change based on susceptibility Age of plant
48
COMPONENTS OF AN IPM Thresholds change based on susceptibility Stress Environmental If action taken is late (threshold too high), control will take longer
49
MONITORING TECHNIQUES Sampling: Flotation Flood area to float Chinch bugs to the surface
51
MONITORING TECHNIQUES Sampling: Irritants Caterpillars and mole crickets Disclosing solution or flushing 1 oz dish soap / gal water
52
MONITORING TECHNIQUES Sampling: Soil sampling Grubs Cut 1 square foot 2” deep Count the grubs Threshold depends on species and stress
53
MONITORING TECHNIQUES Sticky traps Yellow sticky cards Whiteflies and thrips (greenhouse) Hang near top of plant canopy Examine weekly for presence Sticky Tape Scale Wrap around branch to estimate hatching
56
Yellow Sticky Cards
58
Blue Sticky Cards
59
Yellow Sticky Tape
60
MONITORING TECHNIQUES Tree Banding Adults lay eggs under band Non-toxic sticky substance traps adults and hatching eggs Cankerworm control and monitoring http://treebanding.com/index.p hp http://treebanding.com/index.p hp http://treebanding.com/index.p hp http://www.treebands.com/ http://www.treebands.com/
61
MONITORING TECHNIQUES Branch beating Shake or beat branch into net or over sheet to dislodge insects
62
Branch Beating
63
MONITORING TECHNIQUES Pheromone traps Gypsy moth, Mediterranean Fruit Fly… Chemical communication between insects Mating, danger, food… Human pheromones?
65
MONITORING TECHNIQUES Pheromone traps Pheromone traps used to lure adults Determine presence, mating or egg laying Estimate hatching Not effective to determine population or control
66
Pheromone Trap
70
MONITORING TECHNIQUES Frass collection Gypsy moth Inspecting fecal pellets at base of tree Size and amount Collect with cups or sticky cards
74
MONITORING TECHNIQUES Pitfall Traps Funnel in ground to catch crawling insects
75
MONITORING TECHNIQUES Degree days Predict growth stage or presence Growth rate of insects is closely related to temperature Higher the temp, the faster the rate Indicates when insect is most susceptible to control
76
MONITORING TECHNIQUES Degree days: amount of accumulated heat 1 degree day (DD) = 1 degree over threshold temperature Lower threshold is the temp when an insect grows Every degree (daily average) over the lower threshold = 1 degree day Subtract the average daily temperature from the lower threshold to get the number of degree days
77
MONITORING TECHNIQUES Every pest has a specific: Lower threshold temperature under which no development will occur Number of degree days needed to complete life cycle
78
MONITORING TECHNIQUES Elm leaf beetle 52 F is lower threshold Starting March 1, count DD 700 DD is the susceptible stage of control
