General And Ag Flashcards
(222 cards)
Natural forces are important because:
a) you cannot do anything about them
b) they can cause pest populations to rise and fall
c) you can never spray anywhere in the winter time
d) the rain and wind always makes it necessary to respray the area.
they can cause pest populations to rise and fall
Biological control:
a) is always 100% effective
b) is never complete
c) never occurs naturally
d) always interferes with commercial chemical control operations.
is never complete
Resistance to pesticides develops in pests species:
a) because some applicators use the least expensive chemicals
b) the chemical companies plan it to happen
c) the pesticides are not poison enough
d) rarely does any pesticide kill all the pests and those that survive pass this ability on to their offspring.
rarely does any pesticide kill all the pests and those that survive pass this ability on to their offspring.
Integrated Pest Management practices include the use of:
a) chemical pesticides
b) cultivation and barriers
c) sanitation and traps
d) all the above.
all the above.
In the case of insects:
a) they are only important because they give entomologists something to talk about
b) they must all be killed as soon as possible
c) about 99% of all species are of minor importance
d) they all feed on plants which could be eaten by people.
about 99% of all species are of minor importance
The insect thorax:
a) is where the insect antennae are located
b) supports the legs and wings (if present) of the adult insect
c) is always a very small orange spot on right side of the head
d) is difficult to distinguish from the legs.
supports the legs and wings (if present) of the adult insect
An example of an Arachnid is:
a) a butterfly
b) an insect
c) a spider
d) a pigweed.
A spider
The use of host resistance:
a) helps keep pest populations below harmful levels
b) means that any pesticide use will not result in killing the host
c) involves treating the host with insecticides repeatedly at low rates so as not to kill it
d) should always be discouraged because it is never effective.
helps keep pest populations below harmful levels
Screens and other barriers:
a) are no longer effective because insects have learned to avoid them
b) are too ”old fashioned“ to work
c) can be a major way of controlling pests in some situations
d) should always be painted red or yellow to help repel the pest.
can be a major way of controlling pests in some situations
The major objective in outdoor chemical pest control is:
a) to cover the entire surface to be protected with a residue
b) rely on drift to reach the ”hard to get“ areas
c) use the most toxic chemical possible to reduce the number of applications
d) spray every other day to stay ahead of pest buildup.
to cover the entire surface to be protected with a residue
May feed on plants but the main
concern is that toxin produced by
this insect may be toxic to horses
blister beetle
This insect is often overlooked
by growers but probably causes
considerable damage
potato leafhopper
The main problem associated with
this pest is larval feeding on roots
which may cause lodging. The
insect is
corn rootworm
These insects often migrate from
maturing wheat fields to suck
plant juice from seedling corn.
The insect is
chinch bugs
Pest information from traditional
cotton-producing states can help
guide Kansas cotton producers but
adjustments will need to be made
because
the growing season is shorter
Damage occurs as these insects
move from maturing wheat fields.
These insects are
thrips
Considered the number one insect
pest of alfalfa throughout Kansas
alfalfa weevil
Dry years seem to favor survival
of this pest which can damage the
crop from mid- to late summer
grasshopper
These insects seem to be slowly
migrating from east to west across
Kansas. The insect is
Japanese beetle
Damage from this insect usually
occurs within the first two weeks
of planting but mainly in eastern
Kansas. This insect is
black cutworm
Damage occurs if these insects
migrate from maturing wheat
fields to suck juice from seedling sorghum
plants: These insects are
chinch bugs
Larval feeding by this insect often
causes a “blasted” appearance to
sorghum heads. These insects are
sorghum midge
Early season stalk tunneling by
these insects may cause late season
lodging. These insects are
sugarcane rootstock weevils
These insects seem to feed on
sorghum as a last resort but may
cause yield loss if they feed on
developing grain. These insects are
false chinch bugs
