Abstract:

Marking of the fowl tick, Argas persicus (Oken), with fluorescent dyes was used as an aid in collecting and counting ticks during pesticide trials in poultry houses. Saturated solutions of the dyes dissolved in acetone were applied to the dorsum of individual ticks at a rate of approximately 3ยต liters/tick. The marking is quite durable, lasting for more than a year on ticks in the laboratory and at least 6 weeks on ticks released and later re- recovered from poultry houses. Several fluorescent dyes were applied to known numbers of adult ticks released in poultry houses. All ticks, alive or dead, bearing a specific dye were searched for and collected at weekly intervals after houses were treated with aqueous sprays of insecticides. In 1 test, both ultraviolet and white light were utilized to search for known numbers of marked and unmarked ticks. Searching for unmarked ticks was time consuming, and only 50% of the original number was collected, compared with 75% and 98% for 2 groups of marked ticks. In a later test, 800 marked ticks were released in each of 3 poultry houses, and collection of ticks from these 3 houses at the end of a 6-week period was 87.4%.
