Effect of Alarm Chemicals and Predator Kairomones on the Behaviour of Two Species of Mosquito Larvae

Derek M. Roberts, Nargis Al-Alawi, Mai Al-Gharibi · Sultan Qaboos University Journal for Science · 2019 · 10.24200/squjs.vol24iss1pp18-22

Mosquito larvae have developed a variety of responses to reduce the risk of predation, but this requires them to be able to identify the different species of predators and respond accordingly. We investigated the behavioural response of two mosquito species to three chemical signals: kairomones from two predators, and …

Comparison of the Physiological age of Adult Resting Versus Flying Culex Quinquefasciatus (Diptera: Culicidae)

Derek M. Roberts · Sultan Qaboos University Journal for Science · 2010 · 10.24200/squjs.vol15iss0pp9-17

Relatively little is known about the physiological age of resting mosquitoes. In this study, Culex quinquefasciatus Say had a similar proportion of males (75%) in the resting as in the flying population (76%), but among the females, there were significant differences between the physiological age of the resting and fly …
