USING THE OVIPOSITION TRAPS FOR INVASIVE MOSQUITOES SURVEILLANCE - CASE OF STEGOMYIA ALBOPICTA SKUSE, 1894 (DIPTERA: CULICIDAE)

摘要

The Asian tiger mosquito, Stegomyia albopicta, is originally an oriental species that has in the last couple of decades invaded and established itself in the USA, Central and South America, Africa and Europe. Since this species is an important vector of dengue and more than 20 other arboviruses (arthropode born viruses) in countries throughout the world, its rapid spread in Europe is viewed as a matter of great public health concern in all countries. In project “Surveillance of invasive invertebrate St. albopicta in Montenegro“ during 2012. on Montenegro coast 41 black plastic oviposition traps were used. Ovitraps were placed in green, shaded, easily accessible places, on the ground with a free space above of at least 1 meter. The ovitraps were placed at used tire storage places (4), urban (11), semiurban (13), main resting places (12) and one border crossing. The trap stations were kept fixed for the whole season and inspected every 10th day, from 07st May to 30th October. All strips from the traps were dried before counting the eggs and after counting they were placed in glass pots with the same collected water from the traps, to grow the larvae and adults. Mosquitoes were identified morphologically by using the diagnostic keys. After breeding and the mosquitoes determination, glass pots with content: water, strips, larvae and adults; were kept in freezer 48 hours, than defrosted and spilled to prevent contamination. Using this kind of oviposition traps 80.582 eggs were counted from 671 positive traps, from total 738 just 67 traps were negative.
