2. IPM and Multiple Pests My talk today: Managing 2 or more pests on the same plant with conflicting control choices.
Pepper example: WFT and pepper weevil
PEW controls—Vydate & pyrethroids—eliminate Orius and explode WFT
WFT controls—spinosad/spinetoram, Beleaf, & Orius
3. Pesticide Choice Conflict
4. How reduce conflict? Eliminate PEW hosts
Introduce Catalaccus parasitoids into nightshade (NS)
Use least-toxic PEW’icides
Monitor movement PEW with traps
GPS GIS mapping of PEW and NS
6. Pepper Weevil Management Situation:
PEW is the system driver
Controlled by frequent and heavy doses of carbamates and pyrethroids
Results:
Elevated resistance to oxamyl
No beneficial activity
Not sustainable
9. Pepper Weevil Management Insights and Innovation:
Determined alternate host is nightshade
Partial solution: attempt to eliminate nightshade
New tool -- Catolaccus to parasitize PEW eggs
Program:
Release Catolaccus into nightshade reservoir for reduced PEW populations
15. Results Summary 2000-2002: High infestations
2003: 45% reduction
2004: 64% reduction
2005: 76% reduction
16. Final Result: Control of PEW and WFT Use 3-tiered system to reduce PEW population available for crop
Monitor PEW outside and inside crop
Use least toxic insecticides
Monitor and identify thrips population in crop and surrounding vegetation
