Maintenance and transportation of large numbers of female mosquitoes collected during an interval of several days may be performed easily and simply without significant mortality. Small cages used to collect were carried in large transport boxes of styrofoam. The mosquitoes, 10 to 15 females in each cage, were permitted to feed daily on blood and a 10% solution of honey. The transport boxes were kept at 21 C by use of ice in plastic bags. Important to high survival and egg production for the species of Aedes collected in Northern Michigan was the blood-feeding in the field within a few hours of capture and the maintenance of proper humidity in the transport boxes.
