A study on rodent ectoparasites in bandar abbas: The main economic southern seaport of Iran
A number of vertebrate animals will invade domestic and commercial premises in search of food and shelter. In doing so, they may be involved in the transmission of disease, soiling and destroying commodities and packing, damaging equipments, buildings and installations, and causing a nuisance. Rodents are the most important animal in this view (Burgess, 1998). The economic importance of rodents is fourfold: a) Destruction or contamination of foodstuffs by rodents amounts to millions of dollars annually. b) Damage to buildings and manufactured goods are estimated in the millions of dollars per annum. c) Damage to insulated wiring, earthen dams, and forest products costs additional dollars each year, and the damage to the insulation of electrical wiring creates fire hazards. d) To the costs of disease and of damage, destruction, and contamination should be added to the cost of rodent control and totals billions of dollars. They are the largest order of mammals, representing 43% of specific global mammalian diversity, and including 443 genera and 2021 different species (Saluzzo and Dodet, 1999). Rodents together with arthropod ectoparasites can play an important role in distribution of the arboviruses, streptococcal infections, choriomeningitis, plague, tularemia, leptospirosis, spirochaetosis, etc (Manson and Stanko, 2005). Arthropod ectoparasites are a diverse and highly adapted group of animals that inhibit the external body surfaces of vertebrates. They may live permanently on their host, or occupy the host’s nest and immediate environment, and visit the body of the host periodically. In either case, there is a close dependency on the host for various lifesustaining resources.
