Effects of marking methods and fluorescent dusts on Aedes aegypti survival

摘要

Background Tracking the movement of mosquitoes and understanding dispersal dynamics is essential for the control and prevention of vector-borne diseases. A variety of marking techniques have been used, including dusts and dyes. Methods In this study, Aedes aegypti were marked using fluorescent dusts (‘DayGlo’: A-19 Horizon Blue & A-13-N Rocket Red; ‘Brian Clegg’: pink, blue & red), fluorescent paints (‘Brian Clegg’: blue, red & yellow) and metallic gold dust (‘Brian Clegg’). Dusting methods were those previously used in mark-release-recapture experiments, including application with a bulb duster, creation of a dust storm or shaking in a bag. Results Results showed marking mosquitoes using a dust storm allowed relatively high survival, compared to unmarked controls (Males: χ2?=?3.24, df?=?4, p?=?0.07; Females: χ2?=?3.24, df?=?4, p?=?0.04), and high marking efficiency. Using a bulb duster showed high survival in male mosquitoes (χ2?=?12.59, df?=?4, p?
