what is the difference between gradual and complete
metamorphosis? why is it important to know the life cycle stage of
an insect? - ANSWER-gradual metamorphosis includes 3 stages:
egg, nymph and adult. there is no pupa stage. complete
metamorphosis includes 4 stages: egg, larva, pupa, and adult.
insects that develop via complete metamorphosis change body
form. larvae may not look at all like adults within the same
species.it is very important to recognize the damaging stage for
best treatment results. many insect are pests in one stage but not
another. especially larval form.
what are beneficial insects? and why are they important to
agriculture? - ANSWER-insects that are pollinators (bees and
butterflies) or pest predators (ladybeetles and lacewings). with out
pollinators many types of plants could not reproduce and
beneficial predators feed on harmful insects, mites, and weeds.

how do mites harm plants? - ANSWER-They suck the plant
juices, eat the underside of leaves, and disfigure the plants they
feed on.
what is an economic threshold? - ANSWER-the level at which
economic losses caused by pest damage, if the pest population
continued to grow, would be greater than the cost of controlling
the pests. reaching an economic threshold usually prompts some
kind of pest control action.
how are thresholds important to a sound pest control strategy? -
ANSWER-setting a treatment or action threshold is essential to
prevent the pests in an area from causing unacceptable injury or
harm. action thresholds vary: sometimes one pest is too many
(like a rat in a food processing facility). Thresholds help producers
and applicators weigh the cost of pest control against the cost of a
pest infestation
what is monitoring and how is it important to a sound pest control
strategy? - ANSWER-regular checking or scouting for pests in a
designated area. Monitoring will tell you what pests are in an
area, how many are in the area, and how much damage they are

causing. it will help determine if the pest population has reached
the treatment threshold and whether control measures have
worked.
what is the difference between prevention, suppression and
eradication of a pest? - ANSWER-prevention means reducing the
chances that a pest will become a problem. suppression means
reducing pest numbers or damage to an acceptable level.
Eradication means destroying an entire pest population.
how could you prevent a pest infestation? - ANSWER-plant weed-
and disease- free seed, choose plants resistant to diseases and
insects, and practice good sanitation. other preventative
techniques include excluding pests from the target area and using
pre-emergent herbicides to kill weed seeds.
briefly define IPM - ANSWER-Integrated Pest Management is an
ecological approach to pest control. it is based on the habitat and
life-cycle of the pest. IPM combines chemical and nonchemical
methods into a single plan or strategy. the goal of an IPM program
is to reduce pest populations to an acceptable level in a way that
