Abstract: To study the damage regulation of Saccharosydne procerus (Mateumura), the honeydew secretion amount and body weight of adults and nymphs under different temperatures were measured, regression equation of body weight and honeydew secretion amount of nymphs was established. The results showed that honeydew secretion amount of low-instar nymphs and adults of different color had no significant change under different temperature, while honeydew secretion amount of nymphs increased significantly in 4th-5th instar. The body weight of female adults was twice of that of male adults. And the body weight of female adults reached the highest under 26 ℃. Temperature had no significant influence on the body weight of nymphs except 5th instar. Honeydew secretion amount showed a significant positive correlation with body weight under different temperature. 4th-5th instar was the most serious damage period. Therefore, the suitable period for control should be 3rd instar and before. When the temperature is low, the requirements of control can be reduced properly.

Key words: Saccharosydne procerus, honeydew secretion amount, body weight, temperature
