Influence of breeding site availability on the oviposition behaviour of Aedes aegypti

Abstract

Despite the importance of the mosquito Aedes aegypti in the transmission of arboviruses, such as yellow fever, Chikungunya fever and dengue fever, some aspects of their behaviour remain unknown. In the present study, the oviposition behaviour of Ae. aegypti females that were exposed to different densities of breeding sites (2, 4, 8 and 16) was evaluated in laboratory and semi-field conditions. The number of breeding sites that were used was proportional to the number available, but tended towards stabilisation. Females used four-six breeding sites on average, with a maximum of 11. A high percentage of eggs was observed in the water, along with the presence of a breeding site termed “favourite”, which received at least 40% of the eggs. The results are discussed in ecological, evolutionary and epidemiological approaches.

Seasonal field efficacy of pyriproxyfen autodissemination stations against container‐inhabiting mosquito Aedes albopictus under different habitat conditions

“…The skip oviposition behavior of mosquitoes generates multiple larval sources that create problems for mosquito control personnel . The autodissemination strategy exploits the skip oviposition behavior of mosquitoes to distribute pyriproxyfen over multiple containers by ovipositing in multiple habitats.…”

Field comparison of oviposition substrates used in ovitraps for Aedes aegypti surveillance in Salta, Argentina

“…Aedes aegypti immatures develop in water holding containers, and frequently use artificial containers in urban settings as larval habitat, laying their eggs in the container walls above the water line. An individual female of this vector may distribute the eggs among multiple larval sites within the same gonotrophic cycle, a behaviour known as “skip oviposition” (Abreu, Morais, Ribeiro, & Eiras, ). In fact, laboratory and semi‐field tests have shown that most A. aegypti females spread their eggs in multiple larval habitats whenever available (Abreu et al., ).…”

A variety of environmental factors influence the oviposition behaviour of A. aegypti (e.g.…”

Models for Miridae, a cocoa insect pest. Application in control strategies

“…The nonlinear term is related to a specific behavior of some insects species, like Aedes mosquito and also mirids, known as skip‐oviposition behavior. Indeed, according to expert's knowledge, mirids ( S. singularis ) are able to select their breeding sites.…”
