,Host—insect interactions,n mammals and birds the surface covering has become extended to incorporate an outer insulating layer of hair or feathers. These layers have proved to be excellent homes for many different species of permanent and periodic ectoparasitic insects providing them with a relatively constant environment in which to spend their days.

Ingestion of the blood meal,f blood-sucking insects, a brief outline will be given of the major mechanisms involved in vertebrate haemostasis. I emphasize that this is only a brief outline because haemostasis, with its central importance in human health, has been studied in considerable depth, and complete books are produced on this subject alone (Ogston 1983).

Feeding preferences of blood-sucking insects,insect obtains its blood meals, but host choice can go beyond the particular species of host chosen. Insects often choose to feed on particular individuals from among the preferred species, which may well have implications for disease transmission (Burkot 1988).

Location of the host,Thus, lice have only 10–20 antennal receptors and fleas about 50, but the stablefly, which spends most of its time at some distance from the host, has nearly 5000 antennal receptors. Considering two bugs, we see that . has only 56 antennal receptors compared to 2900 on the more adventurous .. Most o
