The effects of water submersion on cattle ticks
Rhipicephalus (Boophilus) microplus is an important vector transmitting hemoparasites in cattle and is, therefore, the
cause of significant loss to cattle production. The control of ticks with synthetic acaricides is partially successful.
However, parasite resistance to these compounds has been reported. This study aimed to evaluate the effects of water
submersion on cattle ticks. Ticks were divided into three weight classes [small (3-10 mg), medium (10-30 mg) and large
(>70 mg)]. All ticks in the small weight class died after immersion in water for as little as 5 mins. Some ticks in the
medium weight class died after immersion for 10 and 15 mins but none in the largest weight class died at any time
point. Entry of water into the body of the small ticks might be via the openings of the stigmata. In conclusion, water
submersion is an alternative way of controlling cattle ticks.This simple technique can be applied to production animals
or pets to control ticks cheaply and safely.
