II.                Narrative

 

The Delta Vector Control District laboratory staff began its full functioning WNV surveillance program with lab techs setting 172 gravid traps on a weekly basis in all of the District’s incorporated cities. In addition to gravid trapping in the populated areas, Encephalitis Virus Surveillance (EVS) traps were set to monitor mosquito activity in rural regions of the district. Mosquito abundance varied throughout the month of April. In general, trap counts were lower than the average trap counts reported from April of last year.

 

Arbovirus screening began on a limited number of mosquito collections in April. No mosquito collections tested positive for West Nile Virus (WNV), St. Louis Encephalitis Virus (SLEV) or Western Equine Encephalitis Virus (WEEV). Historically, the earliest the District has detected WNV activity has been the last week of April. Last year, 2017, the first WNV infected mosquito collections were detected the first week of May and it is anticipated virus activity will begin in May of 2018 as well.

 

Post emergent weed treatments continued as weather permitted and are currently at a 14 day return time. Few Larval treatment requests were made through April above the normal Bti treatment route. Catch-basin treatments were initiated the first week of April to the outlaying communities and Visalia basin treatments started the second week. Aerial photos were received, and the House Mosquito Technicians began inspection of those mapped sites. Zone Techs completed spring mapping and their Field Condition Charts and have begun making inspections and treatments.      

 

There were thirty-eight service requests during the month categorized as follows:

The District has a vacation policy that requires 24 hour notice in order to ensure the operational integrity of the workforce.  Sick leave for doctor, dentist and/ or family medical necessity also requires advance notice- in so much as it is possible.  Illness is unplanned and therefore unscheduled.  Attendance records for the current year are shown in the table.
