7A Pest Exam/135 Accurate Questions withAnswers
Integrated Pest Management - -a process that utilizes inspections and
periodic monitoring to determine if any type of treatment is needed to
reduce pest populations to tolerable levels
-Four Steps in an Integrated Pest Management Program - -1. Inspect the site
for pest problems. || 2. Set pest action thresholds. || 3. Apply pest
management procedures. || 4. Monitor the pest management program (post-
treatment)
-Action Threshold - -the level of pest infestation which requires initiating a
control strategy
-Pest Exclusion - -best way to manage pests, denying entry into buildings
through sealing gaps, installing proper door thresholds etc. some companies
do this work, while other's leave it up to the client
-Pest Habitat Manipulation - -a control strategy that denies pests access to
food, water, and shelter, usually through concentrated sanitation efforts.
factors could include temperature and humidity. critical for controlling
cockroaches and rodents. take care of filthy conditions
-Pest Removal - -most direct method of managing pest populations.
involves lethal trapping (most used) and disposal; live trapping (wildlife and
animals) and removal; and direct removal techniques (such as vacuuming
cockroaches)
-Contact Insecticides and Stomach Poisons - -contact insecticides penetrate
through insect body covering; applied directly to insect or as residue on
surface for insect to crawl through. stomach poisons ingested by insect
during feeding or grooming
-Residual Insecticides and Non-Residual Insecticides - -involves length of
time a pesticide will last. residual insecticides may persist for weeks or
longer. non-residual pesticides break down quickly after treatment
-Desiccants - -part of inorganic insecticides. disrupt the water balance (such
as rapid water loss) of insects that contact them. low hazard to non-target
organisms and not known to develop resistance
-Pyrethrins - -part of botanical insecticides, which are plant-derived.
pyrethrins are constituents of pyrethrum. interrupt the normal transmission
of an insect's nerve impulses. used with synergists, provide quick knockdown
, with little residual activity. used at low rates as flushing agents during
inspection to improve detection of insects
-Synthetic Pyrethroids - -part of synthetic organics, which are laboratory-
produced and contain carbon. mimic the action of pyrethrins meaning they
interfere with the transmission of nerve impulses. quick knockdown activity.
engineered to be more stable and persistent.
-Insect Growth Regulators - -part of synthetic organics, which are
laboratory-produced and contain carbon. chemicals that mimic the juvenile
growth hormone and prevent the immature insect from molting into the
adult stage and, in doing so, disrupt the insect's life cycle by preventing it
from reproducing. chitin synthesis inhibitors often grouped with IGRs so the
insects do not molt. very low hazard to non-target animals. insect-specific
-Baits - -placement makes them inaccessible to people and pets. offer ease
of placement and are odorless. in order to be effective, target pest must
consume bait. less attractive to pests if unsanitary conditions provide
alternate food source
-Dusts - -provide the longest residual activity of the various insecticide
formulations, provided they are carefully applied to dry areas. provide
excellent coverage within cracks, crevices, and other voids. may be used
around electrical outlets. if applied carelessly, dusts can drift into non-target
areas.
-Granules - -formulated for exterior applications where longevity under wet,
hot conditions is desirable. applied around homes as perimeter (barrier)
treatments to manage occasional invaders such as ants, centipedes,
earwigs, etc.
-Wettable Powders - -easy to store, have only a mild odor, and provide
better residual properties than other formulations on porous surfaces such as
wood and concrete. inhalation hazard when mixing powder with water. must
be agitated frequently to keep them in suspension and leave surface residue
when the spray evaporates
-Emulsifiable Concentrates - -oil-soluble products that contain an emulsifier,
permitting them to mix with water. readily adhere to surfaces they are
sprayed on. may stain or damage treatment site or burn any plant foliage
they come in contact with. read label for this.
-Suspension Concentrates - -also known as flowables. finely ground solids
suspended in liquid. require less agitation than wettable powders.
