用牙枝状枝孢霉Cladosporiumcladosporisides(Fres)Derrues的孢子液防治近年新传入广东的湿地松粉蚧Ora-cellaacuta(Lobdell)。室内试验的校正死亡率为82.7%~92.7%;林间试验,每公顷喷孢子量16.5×10 个,20天的防治效果80%以上。因此,芽枝状枝孢霉防治湿地松粉蚧是一种安全有效的防治方法。
The spore solution of Cladosporium cladosporisides (Fres) Derrues was used to control Ora-cellaacuta (Lobdell) newly introduced into Guangdong in recent years. The corrected mortalities in laboratory tests ranged from 82.7% to 92.7%. In the inter-forest experiment, the number of spores per hectare was 16.5 × 10, and the control effect for 20 days was over 80%. Therefore, the Mycobacterium Cladosporium prevention and control wetland mealybugs is a safe and effective method of prevention and treatment.
