Mosquito and Aquatic Training Guide
Compare the different levels of protection afforded by the respirators discussed in this chapter. -
ANS-Air purifying respirators are less effective than supplied air respirators, but acceptable for
use with some pesticides. Dust/mist respirators remove particles and spray mists from
contaminated air. Vapor removing respirators contain both a filter and a prefilter. The half-face
version of vapor removing respirators have one to two cartridges attached to the face piece,
whereas full-face vapor removing respirators use either a cartridge or canister on the mask or
on a hose from the mask to your belt.
Describe how pesticides are assigned to toxicity categories and given signal words. -
ANS-Toxicity and signal words are based on the total formulation. Oral and dermal LD,
inhalation LC, and corrosiveness are all taken into account when determining toxicity
categories.
Describe how you would arrange pesticides in storage to protect the products and containers. -
ANS--separate pesticides by type
-store pesticides only in their original containers
-keep labels intact, legible, and visible
-store dry materials above liquids
-keep dry products away from liquid
Describe how you would manage and dispose of liquid pesticide wastes. - ANS--Wisconsin
Clean Sweep program
-solidification
-return to dealers if unopened
-freeze
Describe some differences between a pesticide label and an MSDS sheet - ANS-An MSDS
contains more detailed and technical information than the label, but should only be used in
conjunction with the label, never in place of it.
Describe some of the general symptoms of pesticide exposure. - ANS-Fatigue, dizziness,
nausea, trembling, blurred vision, fever, convulsions, or even death
Describe some of the health concerns associated with different formulations. - ANS-Both
emulsifiable concentrates and ultra-low velocity formulations are easily absorbed through the
skin.
Describe steps you an take to minimize exposure when mixing and loading pesticides. -
ANS--wear full PPE (gloves, apron, eyewear, and work clothes)
,-read the first aid instructions on the label
-have a supply of clean water and soap on hand
-stand in the crosswind outdoors so the wind blows across your body
-avoid overflow
Describe the beneficial roles of Wisconsin's fish populations - ANS-- Maintain balanced
communities by feeding on aquatic plants, insects, and other fish
- Providing a food source for natural predators
- Fishing for food and sport is very popular in Wisconsin
- Fish farms and hatcheries raise fish for food, feed, fertilizer, bait, and for release into state
waters
Describe the certification requirements for a person who is applying pesticides to waters of the
state. - ANS-One must have a permit from the DNR allowing the use of each pesticide
Describe the difference between labels and labeling - ANS-The label is the information printed
on or attached to the pesticide container or wrapper. Labeling refers to both the actual label and
to all addition product information.
Describe the difference between private applicator, commercial applicator for hire, and
commercial applicator not for hire. - ANS-Private: Use or direct the use of pesticides for the
purpose of producing an agricultural commodity and the applications occur on land owned or
rented by you or your employer or on someone else's land if for exchange of goods or services
between agricultural producers.
Commercial For Hire: not private, on a contract basis
Commercial Not For Hire: not private, not on a contract basis
Describe the events necessary for an herbicide to kill a plant. - ANS--It must be absorbed into
the plant, either through the leaves, stems, or roots
-If necessary, it must then be moved to the sensitive part of the plant
-It must block an important process in the plant
Describe the four stages of the mosquito life cycle, including the main structural features of
each. - ANS-Egg
-generally 1/25 of an inch long
-oblong in shape
-most hatch within three days
-some have lateral extensions that serve as floats; others have spines that trap air to float.
-numerous species glue eggs together to form a floating raft
Larvae
-head, thorax, abdomen
-head bears the antennae, eyes, and mouthparts
-the 8th segment of the cylindrical abdomen bears the respiratory apparatus
, Pupae
-comma shaped
-lasts only a few days
-cephalothorax contains a pair of respiratory structures called trumpets
-abdomen contains a pair of paddle-like structures
Adult
-slender abdomen
-one pair of narrow wings, three pairs of long, slender legs
-elongated proboscis
-head bears a large pair of compound eyes, a pair of antennae, and a large proboscis
-hairs on the antennae are short and sparse in females and long and bushy in males
-thorax contains three segments and bears the wings and legs
-long, cylindrical abdomen is comprised of ten segments; the ninth and tenth segments are
modified for reproduction in both sexes
Describe the function of the adjuvants. - ANS-An adjuvant or additive is a chemical added to a
pesticide or spray tank to modify the product's physical properties and/or enhance pesticide
performance. Manu pesticide formulations already contain adjuvants like: wetting agents and
emulsifiers, spreaders, stickers, and penetrants.
Describe the general growth habits of, means of dispersal, and potential problems caused by:
Emergent Aquatic Plants - ANS-Growth habits: rooted in relatively shallow water so most of their
growth extends above the water line, or they grow in water-saturated soils.
Dispersal: spread by an underground root system and new emergent plants can occur almost
anywhere in the network. Examples: cattails, arrowhead, bulrushes, and purple loosestrife.
Problems: Dense and can limit recreational boating, fishing and swimming, however they
provide habitat for wildlife and shouldn't be controlled except in the case of purple loosestrife.
Describe the general growth habits of, means of dispersal, and potential problems caused by:
Free-floating and rooted floating-leaved aquatic plants - ANS-Growth habits: plants whose
leaves float on the water surface (i.e. water lilies)
Dispersal: Free-floating- wind; Rooted- wind
Problems:
Free-floating - i.e lesser duckweed; form green blanket up to 2" thick on water surface; difficult
to control in large bodies of water.
Rooted - examples: water lilies, spatterdock, American lotus, and watershield. These plants
provide valuable cover for fish and are rarely a problem
Describe the general growth habits of, means of dispersal, and potential problems caused by:
Free-floating, filamentous, and "rooted" algae. - ANS-Growth habits: can be found floating or
