| seasonal distribution and habitat selection by aedes albopictus and ae. riversi (diptera: culicidae) in northern kyushu, japan. | temporal and spatial distribution of adult and larval aedes albopictus (skuse) and aedes riversi bohart & ingram were studied on a small island and coastal area of northern kyushu, japan. adults of ae. albopictus attracted to human bait were distributed uniformly in an evergreen forest, a citrus orchard surrounded by forest, and an area disturbed by humans, whereas ae. riversi was confined to evergreen forest and its adjacent area. adults of both species occurred from may through october. althou ... | 1992 | 1495046 |
| characterization of wolbachia infections and interspecific crosses of aedes (stegomyia) polynesiensis and ae. (stegomyia) riversi (diptera: culicidae). | prior studies have identified a complicated pattern of interspecific hybridization between members of the aedes (stegomyia) scutellaris (walker) mosquito group, which includes medically important vectors of bancroftian filariasis and dengue. here, we report that two members of the group, aedes polynesiensis marks and aedes riversi bohart & ingram, are both infected with intracellular wolbachia bacteria. sequencing of the wolbachia wsp gene demonstrates that the infections differ from each other ... | 2004 | 15535618 |
| interspecific hybridization yields strategy for south pacific filariasis vector elimination. | lymphatic filariasis (lf) is a leading cause of disability in south pacific regions, where >96% of the 1.7 million population are at risk of lf infection. as part of current global campaign, mass drug administration (mda) has effectively reduced lymphatic filiariasis prevalence, but mosquito vector biology can complicate the mda strategy. in some regions, there is evidence that the goal of lf elimination cannot be attained via mda alone. obligate vector mosquitoes provide additional targets for ... | 2008 | 18235849 |
| male mating competitiveness of a wolbachia-introgressed aedes polynesiensis strain under semi-field conditions. | lymphatic filariasis (lf), a global public health problem affecting approximately 120 million people worldwide, is a leading cause of disability in the developing world including the south pacific. despite decades of ongoing mass drug administration (mda) in the region, some island nations have not yet achieved the threshold levels of microfilaremia established by the world health organization for eliminating transmission. previously, the generation of a novel aedes polynesiensis strain (cp) inf ... | 2011 | 21829750 |
| naturally occurring incompatibilities between different culex pipiens pallens populations as the basis of potential mosquito control measures. | vector-borne diseases remain a threat to public health, especially in tropical countries. the incompatible insect technique has been explored as a potential control strategy for several important insect vectors. however, this strategy has not been tested in culex pipiens pallens, the most prevalent mosquito species in china. previous works used introgression to generate new strains that matched the genetic backgrounds of target populations while harboring a new wolbachia endosymbiont, resulting ... | 2013 | 23383354 |
| population genetic structure of aedes polynesiensis in the society islands of french polynesia: implications for control using a wolbachia-based autocidal strategy. | aedes polynesiensis is the primary vector of wuchereria bancrofti in the south pacific and an important vector of dengue virus. an improved understanding of the mosquito population genetics is needed for insight into the population dynamics and dispersal, which can aid in understanding the epidemiology of disease transmission and control of the vector. in light of the potential release of a wolbachia infected strain for vector control, our objectives were to investigate the microgeographical and ... | 2012 | 22531297 |
| leaf species identity and combination affect performance and oviposition choice of two container mosquito species. | 1. resource diversity can be an important determinant of individual and population performance in insects. fallen parts of plants form the nutritive base for many aquatic systems, including mosquito habitats, but the effect of plant diversity on mosquito production is poorly understood.2. to determine the effects of diverse plant inputs on larval mosquitoes, experiments were conducted that examined how leaves of vitis aestivalis, quercus virginiana, psychotria nervosa, and nephrolepis exalta aff ... | 0 | 20161198 |
| the effects of genetic manipulation, dieldrin treatment and irradiation on the mating competitiveness of male anopheles arabiensis in field cages. | to enable the release of only sterile male anopheles arabiensis mosquitoes for the sterile insect technique, the genetic background of a wild-type strain was modified to create a genetic sexing strain ano ipcl1 that was based on a dieldrin resistance mutation. secondly, the eggs of ano ipcl1 require treatment with dieldrin to allow complete elimination of female l1 larvae from the production line. finally, male mosquito pupae need to be treated with an irradiation dose of 75 gy for sterilization ... | 2014 | 25125089 |
| heritable strategies for controlling insect vectors of disease. | mosquito-borne diseases are causing a substantial burden of mortality, morbidity and economic loss in many parts of the world, despite current control efforts, and new complementary approaches to controlling these diseases are needed. one promising class of new interventions under development involves the heritable modification of the mosquito by insertion of novel genes into the nucleus or of wolbachia endosymbionts into the cytoplasm. once released into a target population, these modifications ... | 2014 | 24821918 |
| detritus type alters the outcome of interspecific competition between aedes aegypti and aedes albopictus (diptera: culicidae). | many studies of interspecific competition between aedes albopictus (skuse) and aedes aegypti (l.) (diptera: culicidae) larvae show that ae. albopictus are superior resource competitors to ae. aegypti. single-species studies indicate that growth and survival of ae. albopictus and ae. aegypti larvae are affected by the type of detritus present in containers, which presumably affects the amount and quality of microorganisms that the mosquito larvae consume. we tested whether different detritus type ... | 0 | 18533429 |
| the phenetic structure of aedes albopictus. | the large and recent migrations of the main vector of the chikungunya virus, aedes albopictus, raise questions about the epidemiological impact of possible microevolutionary changes in new territories. quantitative traits are suitable to detect such changes as induced by environmental adaptations, local competition and founder effects. using landmark-based geometric morphometrics, we compared the size and shape of 22 populations (1572 females) of ae. albopictus. the collection sites covered five ... | 2013 | 22985681 |
| variation in cold hardiness of nondiapausing eggs of nine aedes (stegomyia) species (diptera: culicidae) from eastern asia and pacific islands ranging from the tropics to the cool-temperate zone. | variation in cold hardiness was studied in the laboratory for the nondiapausing eggs of nine aedes (stegomyia) species from eastern asia and pacific islands, ranging from the tropics to the cool-temperate zone. species included were aedes aegypti (l.), aedes albopictus (skuse), aedes flavopictus yamada, aedes galloisi yamada, aedes hensilli farner, aedes palauensis bohart, aedes paullusi stone and farner, aedes riversi bohart and ingram, and aedes scutellaris (walker). for species with distribut ... | 2011 | 21485356 |
| interspecific transfer of a wolbachia infection into aedes albopictus (diptera: culicidae) yields a novel phenotype capable of rescuing a superinfection. | wolbachia are maternally transmitted obligate bacteria that occur naturally in many arthropods. the phenotype observed in mosquitoes is known as cytoplasmic incompatibility (ci), which results in reduced or absent egg hatch in crosses between individuals with different infection types. applied mosquito control strategies propose that by releasing individuals infected with a wolbachia strain that differs from that in the natural host population, ci could be used to suppress or replace mosquito po ... | 2014 | 26309306 |
