All sticky papers with insects were examined under ste- reomicroscope in the laboratory. Mosquitoes were identi- fied to species level. Only Ae. aegypti and Ae. albopictus were processed for detection of the virus. The abdomens of the mosquitoes were pooled (five in a pool), while the head and thorax of each mosquito were kept individually in Eppendorf tubes at 20 °C until real-time RT-PCR processing.
