||PROFESSOR VERIFIED|| ||BRANDNEW!!!||
How can pesticide selection be used to conserve or enhance
activities of natural enemies - ANSWER-certain long lasting
pesticides create long lasting residues which can be very
damaging to natural enemies
How can ant control be used to conserve or enhance activities of
natural enemies - ANSWER-allows higher efficiency of biological
control of honeydew secreting organisms because ants wont be
attacking the biological agent
How can harvest practices be used to conserve or enhance
activities of natural enemies - ANSWER-leaving some of the crop
unharvest allows for an areas for natural enemies to exist and
control pests at a later date
Describe the typical lifecycle of an insect parasitoid - ANSWER-
An adult parasite lays an egg in an organism, the egg hatches
within the organism as an larvae and feeds on the organism
,2|Page
inside, after killing the host organism the parasite larvae pupates

quadrigemina
Why is biological control of weeds more successful in rangelands
and aquatic weeds of agriculture crops - ANSWER-in these areas
they respond well to the slow rate of control and are often
undisturbed by humans or other pest control actions
What is the role of crop competitiveness as a biological approach
to weed control - ANSWER-if a crop can out compete a weed
species by out shading, limiting resources, or other methods the
likelihood of it success are much higher and the survival of weed
is much lower
Define a disease suppressive soil - ANSWER-Soil where disease
incidence remains low even though a pathogen, susceptible host,
and a disease is present
, 4|Page
What advantages are associated with using cultural controls in an
IPM program - ANSWER-Generally familiar, simple, inexpensive,
and easily incorporated into management systems with little
modification
How can site selection effect pest problems - ANSWER-pest
problems can be avoided by selecting site that are pest free,
choosing a crop that is well suited to the site
What are six important sanitation techniques - ANSWER-certified
seed/tubers/transplants
thoroughly clean with steam or pressurized water all equipment
between fields
Use of clean irrigation water
Use screens in areas where water is being brought from canals or
ditches
remove or clean up unharvested materials
eliminate weedy boarders
