Development and survival of the tick Hyalomma dromedarii Koch under laboratory conditions

Developmental cycle of the tick Hyalomma dromedarii as influenced by changes of temperature and humidity was studied under laboratory conditions. Feeding and metamorphosis of developmental stages were observed under standard laboratory conditions, the metamorphosis was traced at exposure to temperature of 28 degrees C, 80% RH to alternating diurnal climate 40 degrees C, 25% RH and 20 degrees C, 80% RH and alternating humidity of 40/100% and 60/100% RH at a constant temperature 30 degrees C.
