Female Culex pipiens abundance (collections) in the Sacramento Metropolitan Area

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.

Usage

data(abund_sma)

Format

A data frame with one row per collection event (for a total of 1552 collection events) and 6 variables:

lon

Numeric. Longitude in decimal degrees (WGS84).

lat

Numeric. Latitude in decimal degrees (WGS84).

total_females

Integer. Total number of female Cx. pipiens captured in the event.

date

Date. Exact collection date (local).

trap_nights

Integer. Number of trap-nights for the event.

trap_type

Character. Acronym for trap type used to collect mosquitoes. These include: "NJLT" (New Jersey Light Trap), "GRVD" (Gravid Trap), and "MMT" (Mosquito Magnet Trap).

Source

Constructed from sample_collections in the vectorsurvR R package.

Details

Derived from the vectorsurvR sample datasets by:

1. 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.

2. Summing counts and trap-nights per unique location–date–trap type.

3. 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).
