5.0 AQUATIC & MOSQUITO EXAM
2025/2026 UPDATED EXAM WITH
VERIFIED SOLUTIONS.
Know the Law: Is overspray prohibited under all circumstances? -
correct answer -Yes
Know the Law: Is significant drift considered a negligent,
prosecutable action? - correct answer -Yes.
Know the Law: Is the applicator responsible for preventing
overspray and drift? - correct answer -Yes.
Describe the common ways that nontarget plants and animals
become exposed to pesticides and how to prevent or minimize
such exposure. - correct answer --*plants*: become exposed
through drift, overspray, and sometimes irrigation/surface water.
Can prevent/minimize this by not applying at too high of a rate
and paying attention to weather.
-*pets*: pets or their food, water, dishes, and toys become
contaminated. If pets are already treated with a tick/flea pesticide,
the addition of this new pesticide could cause poisoning. To avoid

this, keep pets and their food/objects removed from application
site, make sure pet hasn't already been treated with pesticides,
and if they have, consider using a different class of pesticide than
the one the pet already has been exposed to. Keep REIs in mind.
-*Insects*: drift or transport through flowers of plants via
pollinators may be the cause. This can be avoided by not using
long residual products for controlling mosquitoes, not applying
pesticide while bees are foraging or while flowers are open.
-*Fish and Wildlife*: drift/overspray or runoff. Minimize it by not
using toxic herbicides where fish have no chance to escape the
toxins; if treating coves, apply near shore so fish can escape.
Avoid removing all plants with herbicide at once to avoid low DO
and fish kills; notice farmers of a pesticide use so they don't let
the livestock drink the water for the certain amount of time
Summarize the label info regarding pollinator protection. - correct
answer -- "Do not apply [product name] while bees are foraging.
Do not apply [product name] to plants that are flowering. Only
apply after all flower petals have fallen off."
Explain who is responsible for advance notification to beekeepers.
- correct answer --the landowner
Compare the cause of, and difference between, pest resurgence
and a secondary pest outbreak. - correct answer --*pest
, Page | 3
resurgence*: loss of predators and parasites allows target pest to
rebound and even surpass pretreatment levels because of lack of
predators
-*secondary pest outbreak*: loss of predators andd parasites
allows a different pest to rebound because of a lack of predators
for them
Describe the kinds of impacts pesticides can have on fish and
wildlife. - correct answer --kill
-growth reduction
-behavioral changes
-decreased reproduction
Explain how pesticide applications can lead to oxygen depletion
and fish kills and how to avoid the problem. - correct answer --
vegetation death in lake consumes oxygen through
decomposition
-avoid this problem by making several smaller applications vs.
one big one. Never treat more then 30-50% of surface area at
once
Know the Law: T/F Landowners must provide advanced
notification of applications of pesticides that are highly toxic to

bees to any beekeeper who has bee yards within 1.5 miles of the
application site and who requests such notification. - correct
answer -True
Describe the impact that pesticide resistance can have on pest
management. - correct answer --pest management becomes
more difficult because the population will be increasingly resistant,
rendering pesticide treatments less effective or useless. If this
happens, a tool for managing pest will have been lost
Describe how pesticide resistance arises in a pest population. -
correct answer --when pest is treated with pesticide, resistant
members of the population will survive and repopulate, increasing
the resistant population
List the factors that influence the development of resistance in a
pest population. - correct answer --frequency of resistance in pest
population before you use pesticide(s) in question
-chemical diversity of pesticides used (always using same
pesticide or family of pesticides won't be killing any pests resistant
to them)
-mode of action of the pesticide you use (resistance more likely if
pesticides have very specific modes of actions)
