A dataset of mosquito collection events used to quantify abundance of female Culex pipiens in the Sacramento Metropolitan Area (Sacramento, Placer, El Dorado counties, California, USA). Each row represents a single collection event at a specific location and date.
data(abund_sma)A data frame with one row per collection event (for a total of 1552 collection events) and 6 variables:
Numeric. Longitude in decimal degrees (WGS84).
Numeric. Latitude in decimal degrees (WGS84).
Integer. Total number of female Cx. pipiens captured in the event.
Date. Exact collection date (local).
Integer. Number of trap-nights for the event.
Character. Acronym for trap type used to collect mosquitoes. These include: "NJLT" (New Jersey Light Trap), "GRVD" (Gravid Trap), and "MMT" (Mosquito Magnet Trap).
Derived from the vectorsurvR sample datasets by:
Filtering to female Culex pipiens collection records within the Sacramento Metropolitan Area (SMA) using point-in-polygon against the union of Sacramento, Placer, and El Dorado county boundaries.
Summing counts and trap-nights per unique location–date–trap type.
Coordinates are kept as WGS84 (EPSG:4326).
This sample dataset is intended for examples, mapping, and vector-index workflows. It is not official surveillance output. Dates span the same period as the vectorsurvR sample (e.g., 2015–2021).
