The traditional view of interactions between arboviruses and their arthropod vectors is that vector hosts become increasingly resistant to parasites; parasite attenuation occurs; or through the process of coevolution, resistance and attenuation occur in concert. Detrimental effects from arboviruses are only seen when vector and virus are not yet well adapted. Results from this study indicate th...
This study determined the effect of temperature on the gonotrophic cycle of Culiseta melanura and developed a thermal heat summation model to calculate its duration under field conditions. A colony of Cs. melanura was used from New Jersey (F13-F17 generation) and the length of the gonotrophic cycle was observed at 2, 10, 16, 22, 28, 32 and 34 degrees C. None of the mosquitos survived at 2 degre...
WEBSTER, J. M. 1973. Manipulation of environment to facilitate use of nematodes in biocontrol of insects. Experimental Parasitology 33, 197-206. The preand postparasitic phases of entomophilic nematodes are exposed to different microenvironments which should be changed in order to facilitate the use of nematodes as biological control agents of insects. The mixing of “thick water” with nematodes...
For decades the German Mosquito Control Association (KABS) has conducted mosquito surveillance as part of a comprehensive mosquito control programme. During the summer of 2011 hundreds of dead birds, especially blackbirds (Turdus merula), were found infected with the tropical Usutu occurred to investigate whether nulliparous mosquitoes carry the virus. More than 6.000 breeding sites were invest...
Eastern equine encephalitis (EEE) virus perpetuates in an enzootic cycle involving ornithophilic mosquito vectors, principally Culiseta melanura (Coquillett) and avian amplification hosts. To better understand the role of Cs. melanura and Culiseta morsitans (Theobald) in the epizootiology of EEE virus, we collected blood-fed mosquitoes between 31 May and 15 October 2004 at two sites associated ...
Eastern equine encephalitis (EEE) virus is a highly pathogenic mosquito-borne zoonosis that is responsible for outbreaks of severe disease in humans and equines, resulting in high mortality or severe neurological impairment in most survivors. In the northeastern United States, EEE virus is maintained in an enzootic cycle involving the ornithophilic mosquito, Culiseta melanura (Coquillett) and p...
Most information about the systematics and bioecology of Belgian mosquitoes dates back from before 1950, and only scattered information was produced during the last decades. In this paper we review and update the list of mosquito species recorded in Belgium, from first report (1908) to 2015. Six genera and 31 species were recorded so far, including 28 autochthonous species and three invasive al...
