A pre-attachment aggregation pheromone in the adult metastriate tick Hyalomma dromedarii Koch (Acarina: Ixodidae).

In vitro investigation demonstrates the existence of pheromone-regulated movement in the metastriate tick H. dromedarii before host contact. Males exhibit significant assembly to material of females.

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.
