PUBLIC NOTIFICATION INFORMATION (provide a short description of notification plan, i.e., timing, frequency, languages other than English, etc.): Public will be notified in the spring of mosquito su rveillance and control activities planned for the season. The public will also be notified of the relevant ar bovirus information and control activities through various media outlets as needed through the course of the mo squito season. Washington County’s program is a joint effort between the County participating Cities, Clean Water Services, Tualatin Hills Park and Recreation District, Hillsboro Parks, and Beaverton School District. Public notification of actual pesticide applications will be the responsibility of the agency making the applications.Vector Control Pesticide Use Plan: District Name : Washington County

TARGET PEST INFORMATION



### IMPORTANT: COMPLETE ONE SH EET FOR EACH TARGET PEST

Target Pest: Check only one target pest per worksheet

.

Mosquito Larvae Domestic Rat Domestic Fly

Mosquito Adult Other Pest (specify)

MONITORING METHOD/TREATMENT THRESHOLD

Monitoring Method: Standard 4 oz dipper; mosquito samples w ill be identified to species and counted.

Treatment Threshold: 1 mosquito per dip for mosquito species with high capacity to vector disease, including (but not limited to) Culex pipiens, Culex tarsalis, Culex stigmatasoma and Aedes japonicus

.

5 mosquitoes per dip for species with a low capacity to vector disease or cause nuisance/livability concerns, including (but not limited to) Aedes vexans, Coquillettidia perturbans, and Culiseta

inornata

EFFICACY SAMPLING A representative number of sites treated with ei ther a bacterial product or a surface film will be sampled 24 to 72 hours post-treatment using standard dippers, the number of mosquitoes per dip will be compared with pre-treatment numbers for that site . Instar stages of the larval life cycle will be compared with pre-treatment instar stages.

A representative number of sites treated with an insect growth regulator will be sampled 24 to 72 hours post-treatment (and every 2 weeks thereafter); pupae samples will be co llected and transported to the lab alive for rearing to determine if they reach the adult stage in life cycle.

SURVEILLANCE FOR IMPACTS ON NON-TARGET SPECIES Presence or absence of non-target organisms will be noted for both pre- and post-treatment samples. Washington County does not have the resources fo r more in depth evaluations. We will rely on published studies of non-target effects to determine larval control strategies.

Target Pest: Check only one target pest per worksheet

Mosquito Larvae Domestic Rat Domestic Fly

Mosquito Adult Other Pest (specify)

MONITORING METHOD/TREATMENT THRESHOLD

Monitoring Method: Adult mosquitoes will be m onitored using Gravid and CO2 Baited EVS traps set at over 80 locations through out Washington County. Other Gravid and CO2 baited EVS traps will be placed around the county based on adult mosqu ito complaints. All mos quitoes collected will be counted and identified to spec ies. Pools of selected mosquito es will be RAMP tested by the county and/or sent to the Oregon State University Veterinary Diagnostic La boratory (OSU VDL) for testing if needed.

Treatment Threshold: The threshold for control of adult mosquitoes will include the presence of arbovirus in mosquito populations and an eval uation of public health risk, according to the Washington County Health Officer.

EFFICACY SAMPLING If adulticides are used, adult mosquito samples will be collected one night before application is to be applied. Those mosquitoes, trapped the night before , will be placed in a cage in the area to be treated. After the application is applied to an ar ea of concern, the caged mosquitoes will be taken back to Washington County’s Lab to determ ine the effectiveness of the application.

SURVEILLANCE FOR IMPACTS ON NON-TARGET SPECIES Washington County does not have th e resources to monitor the non-ta rget effects of adulticide applications; however, we will make every effort to minimize effects on non-target with proper application techniques including rate, droplet si ze and atmospheric conditions, in accordance with label recommendations and published literature.
