Special cups called “ovitraps” are placed in areas to collect container species such as Ae. japonicus, Culex spp. and Ae. albopictus.
The cups have water inside about halfway up, and are lined with seed germination paper to give the female mosquito a substrate to lay her eggs upon.
These papers are collected by CMMCP staff, and the eggs are counted and then sent into the MDPH lab to be reared and identified to species. If Ae. albopictus is identified, we can deploy additional ovitraps and well as BG-Sentinel traps.
CMMCP deploys these traps in selected areas in our service area to monitor mosquito population and distribution. They are moved if needed to sample in as many locations as possible.
