PART 3B
Objectives
• Introduction to trapping techniques
• Discuss types of pheromone traps
• Discuss application of pheromone traps
• Discuss integration with other tactics
Insect trapping is easy, fun, & practical!
Types of Insect Traps• Passive traps: do not use a lure of any kind,
e.g., pit-fall traps, ground sticky traps, water traps, flight interception trap (beat sheet)
Pit-fall trap with a metal sheet as hood
Interception trap (can be used with or without light)
Types of Insect Traps• Active traps:
– use a lure of some kind, e.g., food, color, shape, light…PHEROMONES
Dome Fly Trap with liquid bait for mass trapping fruit flies
Light trap
Types of Insect Traps• Active traps (contd.): use a lure of some kind
Active/passive trap: yellow water pan trap
Yellow/white Sticky Trap with grid
Use many traps for accuracy
Ball trap for dipteran flies
Insect Pheromone TrapsSpecial attractive traps for flying insects
What are insect pheromones?• Pheromones are chemicals
released into environment in small amounts by special abdominal glands in insects.
• Pheromones are species specific, may stimulate one gender or all genders.
• Male moths detect pheromones with antennae.
• Synthetic sex pheromones are manufactured & used as lures.
Advantages & DisadvantagesAdvantages of Pheromone Traps:
• Are affordable
• If used wisely, can detect low insect populations
• Insect ID not needed
• Easy to install & manage
• Nontoxic, no residue on food
• Can be used season long
Advantages & DisadvantagesDisadvantages of Pheromone Traps:
• May be cumbersome to handle
• Take precautions when handlings (gloves)
• Several traps could difficult to manage
• Knowledge intensive – may need tech support
• Weather sensitive
• Does not tell about plant injury
Parts of a Pheromone Trap
Top section (fixed)
Bottom section (replaceable sticky card with grid)
Metal support
Lure with lure holder
Wing Pheromone Trap
Types of Pheromone TrapsWing Traps
Lure supply: Trece, Scentry, APTIV; trap supply: Great Lakes IPM, Arbico Organics, Gemplers, APTIV
Simple wing trap with grid on sticky bottom
Wing trap with baffles (large trap surface)
These are very popular in IPM due to their easy assemblage, large trap bottom, & low cost of kits!
Suitable for larger moths: armyworm, cutworm, fruitworms
Problem: change of bottom is cumbersome, weather & animals could ruin trap
Types of Pheromone Traps
Lure supply: Trece, Scentry; trap supply: Great Lakes IPM, Gemplers
Delta Traps
Delta traps with sticky insert having a printed grid. Sides fold to hold the sticky insert in place.
>>
These are very popular in IPM due to their easy assemblage, maintenance, less weather damage, & low cost of kits!
Suitable for small moths – diamondback moth, loopers
Problem: small trapping surface
Types of Pheromone TrapsStink Bug Traps
LURE LURE
Lure supply: Trece, APTIV; trap supply: APTIV
Problem: expensive, cumbersome, wind can topple trap or container, too attractive for strangers
Types of Pheromone TrapsMass trapping kits
Lure supply: Trece, APTIV; trap supply: Great Lakes IPM, APTIV
Advantages:Relatively inexpensiveConvenient cleaningLure lasts longer
Disadvantages:Needs a killing agent(“No Pest Strip”)
How to choose the right pheromone traps?
• Goal:
– monitoring? Yes, traditional use of pheromone traps
– mass trapping? May be for home gardeners
• Insect species:
– Pheromone trap for all species are not available
– Consult & work in a group (neighbors)
• Size of the Insect:
– Traps come in all sizes, choose large trap for large moths
• Your convenience:
– Traps must be checked weekly (weather is a major issue)
– Don’t commit if you can’t monitor long-term
