The feeding habits of Glossina.

The feeding habits of 15 species of Glossina have been studied by the identification of their blood meals. Representative samples of the blood meals from each of these species of tsetse fly and from different habitats were collected and 22 640 blood meals were identified. The feeding patterns are characteristic for each species of tsetse fly and do not appear to depend entirely on the availability of different hosts, suggesting that the feeding habits of Glossina are genetically determined. However, a broad grouping can be made into five categories: species feeding mainly on suids, those feeding on suids and bovids, those feeding mainly on bovids, those feeding mainly on mammals other than suids and bovids, and those feeding on most available hosts and on man.The possibility of control by selective elimination of the main hosts of these groups is discussed.

Identification of blood meals of blood-sucking arthropods.

The identification of blood meals of blood-sucking arthropods requires a test which is sensitive enough to detect even partially digested blood and specific enough to identify the various hosts. The technique of preference is the precipitin test which makes use of the specific combination of the serum proteins of the blood. The preparation of the blood meal extract and the procedure for the absorption of the antisera is described and various methods of performing the precipitin test are mentioned. When the hosts involved are closely related to each other it is necessary to use the inhibition test. The blood meal will specifically inhibit, under specified conditions, the agglutination of tanned and sensitized red blood cells which is caused by a suitable antiserum. The procedure adopted for the identification of blood meals derived from a large variety of hosts is described in detail.
