Notes: Available Online: http://www.ejpau.media.pl/volume11/issue2/art-24.html In the present study honeydew excretion process of Coccus hesperidum L. was investigated using modified hygrothermographs for daily measures, following the method applied in the 80’s by Koteja. Diurnal activity of honeydew excretion in different developmental stages of Coccus hesperidum was analyzed. Maximum activity of Coccus hesperidum honeydew production has been observed at afternoon and night hours. The difference size and density of honeydew droplets in relation to the scale insects developmental stage and diurnal rhythm of Coccus hesperidum has been noted.
