Description
Summary:Nosomma monstrosum (Nuttall & Warburton) is a hard tick infesting mainly buffalo and cattle in Sri Lanka. Biological data on the life cycle pattern of N. monstrosum were collected using experimental infestation on New Zealand white rabbits under laboratory conditions. The three-host life cycle was completed within 64–102 days. Eggs hatched after 20–29 days of incubation and the larvae hatched out started feeding which lasted for 2–4 days. After a moulting period of 8–11 days nymphs emerge and they actively fed for 2–4 days. Subsequently the nymphs took 15–18 days for moulting before emerging as adults. Freshly moulted females fed for 7–8 days and remained latent for 4–5 days before starting the oviposition. Females laid 3864–12,520 eggs for 11–17 days. The male: female sex ratio was 8:3 in the adults which were moulted under laboratory conditions. Strong positive correlations were found in female weight with number of eggs laid and REI. Females raised from the first generation of eggs had higher oviposition periods, higher REI, laid ten times more eggs, and lower pre-oviposition periods compared to those collected from the wild. When a suitable host is given, N. monstrosum could successfully complete its three-host life cycle under laboratory conditions.
