II.                Narrative

 

The Delta Vector Control District laboratory staff wrapped up surveillance for Aedes aegpyti mosquitoes and began to work on winter projects. The final inspections for invasive Aedes took place the third week of November.

 

Laboratory staff organized paperwork and items from the 2018 mosquito season and cleaned and corrected hazards that were found during the October safety inspection. All mosquito traps were inspected for faults and those in need of repair catalogued accordingly. Mark Nakata, Biologist, began repair efforts with what materials were available and put together a shopping list of necessary items for the remainder. Crystal Grippin, Biologist, began work editing and updating the invasive Aedes surveillance plan for the 2019 mosquito season. Jesse Erandio, Biologist, began work on his poster being presented at the 2019 annual AMCA conference and worked on the budget for the 2019-2020 fiscal year. Mir Bear-Johnson, Scientific Program Manager, began work on the annual report for the District.

 

Once again, the District hosted the semi-annual examination for certification in Public Health Vector Control on November 15th. Crystal Grippin, Biologist, took the C and D categories of the exam and passed both to become fully certified, making the entire fulltime laboratory staff fully certified at this time.

Due to warm weather, larval treatments to dairy lagoons continued through the second week of November. Technicians continued to respond to service requests as needed. Technicians not assigned to the above mentioned duties were assigned maintenance needs of District grounds, vehicles, equipment, and remediation of safety concerns noted on the semi-annual safety inspection report. Weed control billing statements were generated and mailed out the first week of November and the 2019 weed control book is being generated as sign-up slips are returned.

 

There were twenty-nine service requests during November categorized as follows:

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.
