The cold-hardiness of Dermacentor marginatus using laboratory-reared offspring of ticks collected in Germany was characterized. Investigations of unfed stages revealed that adult ticks suffered 50% mortality at −10°C after 4–5 months, but larvae and nymphs suffered mortality within few days, whereas −15°C was lethal for all stages within a very short period. Larval hatch and moulting of engorged larvae and nymphs did not occur at ≤ 10°C. Embryonic development of eggs with larval hatch was… CONTINUE READING
