Résumé : Maximum flight activity was monitored during early summer sunny days above Murraya paniculata canopies in Fuzhou. Among the various colours tested for sticky traps, brown yellow gave the optimum response in cloudy weather. Consistent catches were obtained 5 meters above the top of M. paniculata canopies, but D. cirri activity was comparatively much less important above citrus canopies. Windless sunny afternoon of early May between 4 p.m. and 6 p.m., produced the highest flying activity. The proportion of females monitored on the brown yellow traps ranged from 58% to 80%. Stress factors linked to extreme seasonal population abundance may explain the higher activity over M. paniculata canopy. D. citri is strongly phototaxic and reacts more to light source than colour. Therefore careful spatial distribution of the catching points is an important component for reliable trapping.
