Report prepared by: Wayne N. Andrews, M.S., Priscilla Matton, M.S

If you have a mission statement, please include it here: In conjunction with the belief that mosquito control is an important public health issue, the Bristol County Mosquito Control Project, under the guidance of the State Reclamation and Mosquito Control Board, strives to serve their membership communities by suppressing both nuisance and disease carrying mosquito populations.

Our goal is to bring mosquito populations to tolerable levels using a variety of scientifically effective methodologies consis tent with applicable laws. Surveillance, water management, biological and chemical controls are performed in an environmentally sensitive manner to minimi ze potential effects on people, wildlife and

the environment.

It is acknowledged that commissioners live or wo rk in the county and that all decisions be made in a fiscally responsible manner. The Project advocates public outreach and education through cooperative efforts with lo cal officials, school departments and the

news media.

DEFINITION: a comprehensive strategy of pest control whose major objective is to achieve desired levels of pest contro l in an environmentally responsible manner by combining multiple pest c ontrol measures to reduce the need for reliance on chemical pesticides; more speci fically, a combination of pest controls which addresses conditions that support pests and may include, but is not limited to, the use of monitoring tec hniques to determine immediate and ongoing need for pest control, increased sanitati on, physical barrier methods, the use of natural pest enemies and a judicious use of lowest risk pesticides when

necessary.

Please describe the purpose of this program: There are two reasons to do surveillance: to monitor mosquito populations and virus levels in these mosquitoes. We work in conjunction with the MA Department of Pub lic Health for testing of samples that are collected. This helps us mo nitor the EEE and WNV activity in the local mosquito populations. With this information we make application, public outreach and water management decisions. Participate in an a nnual collection survey for Cs. melanura with MA DPH, to estimate the population and risk of EEE.

Did the above listed diseases cause human or horse illnesses? YesPlease explain: We have had more EEE activity in our County in the last 5 years or 50 years then any other mosquito control program in the US. We have collected over 100

isolations from both WNV and EEE in the past 5 years. We had 6 repoted WNV human

cases and 2 EEE human cases.

2008 Horse case- Freetown

At what arbovirus risk level did the year begin in your area? (If more than one please list)

WNV: 2

EEE: 2

At what arbovirus risk level did the year end in your area? (If more than one please list)

the document.

Comments: Several towns were in risk category 4 for both EEE and WNV. We met DPH guildlines for Risk Category 5 in New Bedford but the level was never changed. This may be related to the late season activity, however we did have sustained EEE isolations from Oc. canadensis, a human biting mosquito and a horse case in the area. Attached a copy of the MA DPH risk map for late season 2008.

If you have data on compliance with this Act and your program, please list here: Most of our schools have an IPM plan on f ile with the state, however less than 50% contain any mosquito control language. Only schools and daycares the request larviciding or adulticiding from Bristol County Mosquito C ontrol have the proper compliance language.

If you had difficulties with implementation of your program due to this law, please elaborate here: Avoiding this many locations at night makes adulticiding applications very difficult.
