Determine the relationship between vegetation type and mosquito
propagation. Researchers have suggested that mosquitoes prefer to
breed in specific types of vegetation. If that were the case, routine
mosquito surveillance and control programs could be conducted more
effectively and at a lower cost by concentrating Vector Control
efforts on those areas where the identified vegetation is more prevalent.
The Early Action Project would be to identify the marsh plants associated
with high concentrations of adult mosquitoes. The Project Team will
field identify and map the plants associated with specific areas
identified by the County as currently supporting high concentrations
of adult mosquitoes.
Test the efficacy
of various mosquito traps. Various commercial devices have been
advertised for their ability to trap mosquitoes. The Team would
prepare and implement methods for testing these devices in the field
under various weather conditions. The most effective traps could
be used as part of other Early Action Projects.
Examine mosquito
migration paths. Mosquitoes may follow defined migration paths from
marshes to populated areas. Mosquito traps would be placed in concentric
rings around marshes with high concentrations of mosquitoes to determine
if migration paths exist and if so how they can be predicted. If
migration paths could be documented, then mosquito traps may be
used to intercept them. Marsh and weather conditions would be documented
as part of the project along with counts by species of captured
mosquitoes. If migration paths are confirmed and effective traps
are available, then a series of traps would be field tested as a
means of intercepting the mosquitoes.
Map and then
examine at least one pilot area to determine if stormwater structures
serve as important breeding sites for mosquitoes. This project would
utilize various treatment techniques available for stormwater structures
to control mosquito populations.
Design, in conjunction
with current County efforts, a series of dry-deposition experiments
for vector control chemicals that could be used to field-verify
the modeled deposition rates to be conducted as part of Task 8.
This project would be based on the literature search to determine
the general reliability and credibility of dry deposition experiments.
Conduct a caged
fish experiment, modified from the NYSDEC design presented during
Scoping, to determine the acute toxicity of aerial mosquito control
pesticides. Dr. McElroy has prepared and submitted a detailed outline
of such a series of tests.
Determine if
groundwater represents a significant pathway for the introduction
of Vector Control pesticides to the estuaries. Suffolk County developed
and field-tested a meter that measures and collects groundwater
seepage into saltwater bodies. The device could collect samples
for analysis in conjunction with dry deposition sampling, ambient
surface water, and, potentially, biotic sampling. It would form
the basis of a mass-balance fate-and-transport experiment for the
chemicals of interest. The data would also be useful to determine
the background impact of non-Vector Control pesticides.
Conduct a biomarker
assay to determine the exposure of organisms to Vector Control chemicals.
The results of the literature search will determine if such a project
could be conducted in a timely and cost-effective manner to assist
in the development of a management plan. |
