Equipment used for collection of ectoparasites from mammals With the aid of the equipment described above, it was possible to remove 20,000 fleas from 100 California ground squirrels during a period of one week. It was found that most of the fleas were re- moved by suction, those that remained were collected with forceps. AYhen this technique is used it is recommended that the recently killed mammals be placed in paper bags and their carcasses chilled by placing them in a refrigerator for 12 hours at a temperature of 10 degrees to 15 degrees C. Animals removed from the refrigerator in paper bags should be left at room temperature for one hour to permit the fleas to become active. Contents of a single bag, fleas and dead host are next emptied into an enamel pan of suitable diameter and five inches in depth. The active fleas and other ectoparasites seeking to escape from the dead host can readily be picked up by suction in the enamel pan and the fur of the animal. A limited amount of hair and debris may be sucked into the collection jar with the fleas. This extraneous material can be separated from the fleas by covering the mouth of the jar Avith a disc of 18 mesh screen held in place by a screw cap band. When the jar equipped as above mentioned is inverted in an enamel pan most of the fleas pass through the screen into the pan; hair and other debris is retained in the jar by the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
