Hyalomma marginatum is a hard-bodied tick found on animals. This tick has been implicated in the transmission of Bahig virus, a pathogenic arbovirus previously thought to be transmitted only by mosquitoes.
Mosquitoes are the major vectors for arthropod-borne viruses (arboviruses) of medical importance. Aedes aegypti and A. albopictus most prolific widespread mosquito being responsible global transmission dengue, Zika Chikungunya viruses. Characterizing collection circulating in mosquitoes, virome, has long been special interest. In addition to arboviruses, mosquitoes carry insect-specific (ISVs) ...
Mosquito salivary glands (SG) play an essential role in food digestion and pathogen transmission. The function of the salivary components during infection is poorly understood. In this study, female Aedes aegypti mosquitoes were infected with dengue virus serotype 2 (DENV-2) via an artificial membrane feeding apparatus. The mosquito SGs were examined for DENV-2 infection for 14 days post-infect...
It has become difficult in recent years to conduct the direct feeding of mosquitoes on animals because of ethical considerations related to animal experimentation. Thus, the artificial feeding of mosquitoes on blood meals is an important technique in studies on the oral infection of mosquitoes to agents. Since Rutledge et al. (1964) devised the artificial membrane-feeding technique, several art...
a series of ddt irritability tests with adult a. maculipennis typicus and a. superpictus were carried out in the isfahan area in august-september, 1970. the observations on irritability were measured in accordance with the who method arid the natural populations of anopheline mosquitoes were used. the tests were carried out in a light intensity of approximately 8 foot candles. the engorged mosq...
b a ckground: several important diseases are transmitted by mosquitoes. despite of the potential of the occurrence of some mosquito-borne diseases such as west nile, dirofilariasis and malaria in the region, there is no recent study of mosquitoes in west azerbaijan province. the aim of this investigation was to study the fauna, composition and dis- tribution of mosquitoes and the characteristic...
Aedes triseriatus mosquitoes were orally infected with two different California serogroup bunyaviruses (La Crosse and snowshoe hare viruses) and high frequency reassortment occurred in these mosquitoes. Increased viral replication and subsequent gene segment reassortment was noted in the ovaries of mosquitoes that had ingested multiple blood-meals. To determine whether newly generated reassorta...
activity during sleep. Interestingly, the pattern of firing observed is specific to the song heard, suggesting that the neuronal activity carries with it information about the song itself. However, the quality of the juvenile’s song actually worsens after sleep, and improves only with practice the next day. Importantly, this effect is dependent upon sleep per se, as it is observed following day...
before, everything about mosquitoes?their zoological relations, their anatomy, histology and development; the systematic study of genera and species (about half the book) ; their role in the transmission of disease (120 pages) ; and sundry other matters, such as the destruction of adults and larvae, the making of collections; and a bibliography of 20 pages. The author is a professional Zoologis...
We formulate and analyze a delay differential equation model for the transmission of West Nile virus between vector mosquitoes and avian hosts that incorporates maturation delay for mosquitoes. The maturation time from eggs to adult mosquitoes is sensitive to weather conditions, in particular the temperature, and the model allows us to investigate the impact of this maturation time on transmiss...
