A written document was developed to clarify the District's adult mosquito-management tacticsto other interested individuals and agencies. The program described consists of 7 discrete components: 1) initiationcriteria, 2) treatment area delineation, 3) agricultural and land-use practices, 4) meteorological conditions,5) continuance criteria, 6) termination criteria, and 7) factors influencing implementation. The guidelines wereadopted as policy by the District's Board of Trustees in 1998 and have been implemented in each of the last 5years. The adult mosquito population is monitored with 6 Mosquito Magnet™ traps strategically located in therice culture areas. Samples are collected daily and laboratory technicians notify the Adulticide/Airplane Coordinatorof collection results before 1:00 p.m.
