Gypsy Management Flashcards
What are the NA standards for trapping?
1 trap/square mile
More in affected areas to determine where to spray
How are larva detected?
Tree banding with sticky material to catch larva on their daily commute up and down tree.
We do pheremone trapping in BC
Gypsy treatment ?
Ground or air spraying. Can use
BTK
NPV aka gypchek / dispavirus. Inhibits chitin production
Mass trapping
Tree banding (homeowner)
Egg mass removal (supplemental)
Mating disruption (east)
What are 3 natural gypsy moth attackers
Pathogens: BTK NPV entomophaga mamaiga
Parasitoids: introduced works at endemic levels
Predators: mammals birds insects
What are the management objectives for gypsy moth?
- Prevent
- Detect
- Treat/Eradicate
- Communicate about spraying. Communicate with other states at risk.
- Seek new treatments
3 zones for gypsy moth in NA
- established
- expanding
- Not established
- urban vs forest
Mgmt objective and tactics for established
Expanding
Not established
Established: Minimize defoliation and save trees. “Suppression” or “slow the spread”. Foray
Expanding: Invest more effort in extermination/eradication whenever possible. More monitoring. Mass trapping. Consider experimental treatments such as mating disruption.
Not Established: Active monitoring, eradication in all cases is the goal.
Trade name for BTK
Foray
Urban vs Forest
Urban is much more likely to have breakouts due to human assisted migration. Mass trapping and spraying.
Campers could introduce pest to forests. Spraying To abide by law and avoid trade embargos.
