Testudinidae Technical abstract: Nine acaricides (amitraz, carbaryl, chlorpyrifos, cyfluthrin, fipronil, lindane, permethrin, phenothrin, and pyrethrins) were studied for their efficacy in killing the African tortoise tick (Amblyomma marmoreum). Only four of the acaricides (chlorpyrifos, cyfluthrin, lindane, and permethrin) produced 100% mortality within 24 hr of application, and only two (cyfluthrin and permethrin) continued to cause 100% mortality when diluted to as low as 1:10,000. Five of the acaricides (amitraz, carbaryl, chlorpyrifos, cyfluthrin, and permethrin) were studied for toxicity to the leopard tortoise (Geochelone pardalis), the most common host of A. marmoreum. The results indicate that cyfluthrin and permethrin, which were herein found to be the two most effective acaricides for control of A. marmoreum, are also the safest acaricides for use on leopard tortoises. Interpretive Summary: Exotic ticks have been repeatedly reported from tortoises and other reptiles imported into the United States. One of the most commonly reported tick species is the African tortoise tick from Africa and most commonly associated with a number of species of tortoises. Because this tick species is able to transmit heartwater, a fatal disease of cattle and goats, there is concern about the introduction of potentially infected ticks into the United States. Unfortunately there is little information about the safety and effectiveness of pesticides for control of ticks on reptiles. In this study nine pesticides (amitraz, carbaryl, chlorpyrifos, cyfluthrin, fipronil, lindane, permethrin, phenothrin and pyrethrins) were studied for their efficacy in killing the African tortoise tick. The most effective compounds for killing ticks were chlorpyrifos, cyfluthrin, lindane and permthrin with cyfluthrin and permethrin being the safest compounds for use on leopard tortoises. This study was conducted in part by Sandra Allan, currently a USDA Center for Medical, Agricultural, and Veterinary Entomology in Gainesville, Florida employee.
