Thermal behaviour of Anopheles stephensi in response to infection with malaria and fungal entomopathogens

摘要: Temperature is a critical determinant of the development malaria parasites in mosquitoes, and hence geographic distribution risk, but little known about thermal preferences Anopheles. A number other insects modify their behaviour response to infection. These alterations can be beneficial for insect or infectious agent. Given current interest developing fungal biopesticides control Anopheles stephensi were examined test whether mosquitoes showed thermally-mediated infection with entomopathogens rodent malaria, Plasmodium yoelii. Over two experiments, groups An. infected one three entomopathogenic fungi, and/or P. Infected uninfected released on gradient (14 – 38°C) "snapshot" assessments preference during first five days post-infection. Mosquito survival was monitored eight and, where appropriate, oocyst prevalence intensity assessed. Both non-random gradient, indicating some capacity behaviourally thermoregulate. However, chosen resting temperatures not altered by any infections. There thus no evidence that behaviours play role determining they will influence performance against adult
