GEORGIA CATEGORY 41 PEST
CONTROL: MOSQUITO
SURVEILLANCE
When are IGRs effective and why?
4th instar so that it may upset the molting process at the pupal stage
When do conventional insecticides kill?
At any instar level
What is the purpose of surface film agents?
Effective in the larval and pupal stage through mineral oil that
suffocates insects by blocking their ability to breath through their
siphon
How do bats and purple martins affect mosquito populations?
There is no basis for claimed suppression of mosquito biting activity
by bats or purple martins. Their predation is insufficient to
significantly reduce mosquito densities
Biocontrol
use of biological organisms or products to control pest that has little to
no impact on non-target organisms
Bacillus thurigiensis (Bti)
most widely used bacterial protein that kills instars 1-4
Bacillus sphaericus (Bsph)
long residual effects that works against Culex & Anopheline larvae;
Known to cause resistance in some species
, What has been known to battle resistance in mosquito treatment?
Combining Bti & Bsph
Example of an IGR
Methoprene
How does methoprene work?
It disrupts the development from larva to adult
Methoprene
*Disturbs mosquito development from larva to adult
*Shown the development of resistance
*Used in alternation w/ Btw, mineral oil, and pyrethrums
Adulticiding
treating of an area for adult mosquitos and is most cost effective, but
not as quality effective as larval stage intervention
How are adulticides usually applied?
Ultra low volume (ULV) sprays
What are the typical sizes of ground applications of adulticides?
10-25 microns
What are the typical sizes of aerial applications of adulticides?
15-30 microns
What factors should be considered in adulticiding?
*Weather conditions
*Nozzle Type
