Aquatic prey show behavioral modifications in the presence of predation-risk cues that alleviate their risk from predation. Aedes albopictus (Skuse), Aedes japonicus (Theobald), and Culex pipiens L. are invasive mosquitoes in North America, and their larvae are prey for the native mosquito predator, Toxorhynchites rutilus (Coquillett). Ae. albopictus and Ae. japonicus are recent invaders, where...

Understanding mechanisms fostering coexistence between invasive and resident species is important in predicting ecological, economic, or health impacts of invasive species. The non-native mosquitoes Aedes aegypti and Culex quinquefasciatus have been resident in the southeastern United States for over a century. They coexist at some urban sites with the more recent invasive Aedes albopictus, whi...

Dengue, the most important human arboviral disease, is transmitted primarily by Aedes aegypti and, to a lesser extent, by Aedes albopictus. The current distributions of these invasive species overlap and are affected by interspecific larval competition in their container habitats. Here we report that competition also enhances dengue infection and dissemination rates in one of these two vector s...

This study verified the efficiency of ovitraps combined with Saccharopolyspora spinosa and Bacillus thuringiensis israelensis for monitoring Aedes aegypti albopictus in laboratory field conditions. In laboratory, A. aegypti, there was no difference eggs number between treatments grass infusions. For albopictus, average higher infusion. dry season, control. rainy infusion resulted a egg density,...

Environmental temperature is an important abiotic element that plays a significant role in various aspects of the insect life cycle. Insects have evolved different mechanisms to adjust variations order avoid thermal stress over evolutionary time. They been able invade practically every type habitat due these adaptations. Aedes albopictus, Asian tiger mosquito, Southeast forest-dwelling mosquito...

The global re-emergence of chikungunya virus (CHIKV) over the last decade presents a serious public health risk to Australia. An increasing number of imported cases further underline the potential for local transmission to occur if local mosquitoes bite an infected traveller. Laboratory experiments have identified a number of competent Australian mosquito species, including the primary vectors ...

OBJECTIVE To assess infestation of Aedes aegypti and Aedes albopiticus and describe their association with weather conditions and container colonization in urban areas. METHODS The town of São Sebastião in the southeastern coast of Brazil was selected. It was used data from the Dengue and Yellow Fever Vector Control Program of the State of S o Paulo, Brazil, that encompasses entomological sur...

The "Asian tiger mosquito", Aedes albopictus, is highly invasive, an aggressive biter and a major arbovirus vector. It is not currently present on mainland Australia despite being intercepted on numerous occasions at international ports and infesting the Torres Strait of Australia since at least 2004. In the current paper, we describe the invasion and current status of Ae. albopictus in the Tor...

Disease transmission is directly tied to the spatial distribution of disease vectors. The distribution of Aedes aegypti (L.) in the United States has diminished since the introduction of Aedes albopictus (Skuse) in the 1980s. However, Ae. aegypti persists in some urban areas, particularly in south Florida. The pattern of habitat segregation of these two species is well documented, but the consi...

The used tire trade has facilitated the introduction, spread, and establishment of the Asian tiger mosquito, Aedes albopictus, and other mosquito species in several countries of America, Africa, Oceania, and Europe. A strategy for detecting these imported mosquito vectors was developed in Spain during 2003-2004 by EVITAR (multidisciplinary network for the study of viruses transmitted by arthrop...
