title: The effect of some organophosphorus acaricides and the time of application on larvae of common ticks in the Eastern Cape of South Africa.
abstract: Mortality curves of larvae of five common tick species dipped in dioxathion, chlorphenvinphos and oxionthiophos are presented. The mortality of three species of ticks were examined at various times of the day. The results showed that at 14h00 the larvae were more sensitive to acaricide treatments than at other times of the day.
