In opening up new areas of malaria control in Jamaica and checking the results in places where anti-anopheline measures are in force, routine live catches of anophelines are made at regular intervals. Jamaican country houses are so constructed that it is almost impossible to catch mosquitoes in bedrooms, and there are no barns in which anophelines will rest. The practice has been, therefore, to use a grey mule as bait, and to catch all anophelines that alight on the animal in the course of one hour after sunset.
The captures are made with “poofer” tubes, and the mosquitoes are subsequently transferred to lantern globes with meshcovered ends. The lantern globes are sent to the laboratory in Kingston, where dissections are performed as rapidly as possible. Where the distance from the catching station to the laboratory is great, the globes are conveyed in boxes containing ice compartments.
