2023 JB Fall Research Pre-Survey

Our goal with the materials we share is to increase community knowledge and adoption of integrated pest management (IPM) as a strategy for managing invasive Japanese beetles (JB). Beneficial insects such as pollinators are being harmed by pesticide misuse which can be reduced with IPM implementation. This survey has 20 questions and will assist us in quantifying your current knowledge of IPM and JB management. You will likely not be familiar with the terms or subjects that are being questioned, but please still answer each question to the best of your ability. There will be a post-survey after this project is concluded.

Q1. Integrated pest management is: *

A decision-making process that uses multiple tactics for pest management and conserves beneficial insects

Repeating scheduled sprays of pesticides

Spraying pesticides as soon as you see a pest

Using only organic pesticides

Q2. Who can create IPM plans? *

Homeowners

Farmers

Land managers

Everyone

Q3. What is the first step in an IPM plan? *

Choose what pesticides, fungicides, and herbicides to use

Identify the pest species and set damage thresholds

Release a biocontrol agent such as lady beetles

Apply a systemic insecticide

Q4. When you must use an insecticide, which category should you pick from first? *

Systemic insecticides

Broad-spectrum insecticides

Biorational insecticides

Restricted-use insecticides

Q5. How do you identify Japanese beetle grubs? *

C-shaped with thick legs and a brown/orange head

No legs, grey-brown and wormlike

Flat, more than 6 legs, running

Dark brown, no head can be seen

Q6. Small numbers of Japanese beetle adults are feeding on the foliage of your flowering ornamentals. How do you manage them? *

Apply a granular pesticide (ex. Scotts GrubEx) to your lawn

Spray a contact insecticide onto the entire plant, including flowers

Do nothing, small clusters of feeding adults will not attract other beetles

Hand remove the beetles or spray them with soapy water

Q7. Japanese beetle grubs in the soil should only be managed with organic treatments.
*

Yes, Milky Spore is the most effective grub treatment

Yes, nematodes are the most effective grub treatment

No, organic treatments are not always a safer and/or more effective option, it is better to pick a biorational treatment like Scotts GrubEx

No, organic treatments never work and I should pick a strong pesticide like imidacloprid

Q8. Name the IPM control method/tactic that the following action falls under:

I have properly identified the pest as Popilliae japonica (Japanese Beetle) based upon its physical appearance and have evaluated the extent of the damage they have caused.

Monitor/Recordkeeping

Cultural

Identify and Evaluate

Biorational

Q9. Name the IPM control method/tactic that the following action falls under:

I have kept track of what pest species have appeared and when, how many are present, and have kept records of what methods/treatments I have used to manage them.

Organic (OMRI Certified)

Biological

Mechanical

Monitor/Recordkeeping

Q10. Name the IPM control method/tactic that the following action falls under:

I tend to avoid planting species that are preferred by pests I repeatedly encounter and adapt my management plans (watering, mowing, fertilizing) to disrupt pest establishment.

Biological

Monitor/Recordkeeping

Cultural

Chemical

Q11. Name the IPM control method/tactic that the following action falls under:

I have set up traps and have removed JB grubs/adults by hand.

Mechanical

Monitor/Recordkeeping

Biorational

Chemical

Q12. Name the IPM control method/tactic that the following action falls under:

I have created a biodiverse environment that welcomes naturally occurring insect predators, parasitoids, and pathogens to control pest populations.

Identify and Evaluate

Monitor/Recordkeeping

Chemical

Biological

Q13. Name the IPM control method/tactic that the following action falls under:

I have utilized pesticides with relatively low-toxicity and minimal non-target effects to kill only Japanese beetles and not beneficial insects or vertebrates.

Biorational

Organic (OMRI Certified)

Cultural

Biological

Q14. Name the IPM control method/tactic that the following action falls under:

I have applied conventional broad-spectrum chemical pesticides to control pest populations.

Identify and Evaluate

Chemical

Mechanical

Monitor/Recordkeeping

Q15. Your rose bush has some leaf damage. What do you do?
*

Spray an insecticide immediately

Look for the damaging agent and then spray

Monitor the plant for a few days to see if the damage increases

Spray a soil (such as kaolin clay) or oil (such as neem oil)

Q16. Why are systemic neonicotinoid insecticides bad for specifically bees and butterflies?

Neonicotinoids are transferred from soil to leaves

Neonicotinoids are transferred from soil to pollen and nectar

Neonicotinoids degrade in a few days and do not kill pests

Neonicotinoids are not very toxic so they do not kill pests

Q17. What does systemic mean when describing pesticides/insecticides?

The chemical compounds are transferred from soil to roots

The chemical compounds are transferred from soil to pollen

The chemical compounds are transferred from existing leaves to new leaves

All of the above

Q18. The EPA registers conventional and biorational insecticides. Which following statement is correct?

Conventional insecticides save pollinators

Conventional insecticides are toxic to only pest insects

Biorational insecticides are relatively non-toxic to people and have minimal environmental side effects

Biorational insecticides are organic insecticides

Q19. Japanese beetles can be successfully managed by what biocontrol organism?

Milky spore disease

Ovavesicula popilliae, a microsporidian fungal pathogen

Tachinid fly (Istocheta aldrichi)

Tiphiid wasp (Tiphia vernalis)

Q20. Of the images below, which one is Japanese beetle? *
