Effect of water flooding on the oviposition capacity of engorged adult females and hatchability of eggs of dog ticks: Rhipicephalus sanguineus and haemaphysalis leachi leachi

Abstract

Effects of water flooding on the oviposition capacity of engorged adult females and hatchability of eggs of Rhipicephalus sanguineus and Haemaphysalis leachi leachi under laboratory conditions were investigated. The durations of time of water flooding were 1, 2, 4, 6, 12, 24, 48, 72, 96, and 120 hours. Engorged females of R. sanguineus and H. leachi leachi did not oviposit after being flooded for more than 48 and 6 hours, respectively. The preoviposition periods of both species were longer than those of their controls. The number of eggs laid were significantly lower (P
