Control effects of longhorn beetle by attractants and Scleroderma sichuanensis in Dancong ancient tea area

【Objective】To explore the control effect of attractant and Scleroderma sichuanensis on longhorn beetlein Dancong ancient tea area,so as to provide technical support for the green prevention and control of longhorned beetle of Fenghuang Dancong ancient tea tree in Chaozhou.【Method】Attractants were used to study the effect of different hanging heights of ZM-80 type trap on trapping longhorn beetles.Effects of attractants F-8,APF-Ⅰ (ordinary type,durable type, and enhancedtype),honey water,CY-1 and CY-2 on trappinglonghorn beetles were studies with catchers. And the field release method was used to evaluate the effects of different release amounts and release time of S. sichuanensis on the prevention and control of longhorn beetle larvae. And regional prevention and control effect of S. sichuanensis was studied.【Result】The results of trapping effect test suggested that the number of the longhorn beetles was 13.25 with the trap hanging height of 2 m,and the number was 2.15 at the height of 1 m,which showed a significant difference(P<0.05). APF- Ⅰ enhancedtype attractant and CY-1 attractant had better trapping effect on various longhorn beetles. The number of traps was 19.40 and 18.35,respectively,and no significant difference showed between them(P>0.05). According to the test, releasing S. sichuanensis had better control effect on longhorn beetle larvae and the control effect ofreleasing 30000 wasps/ha S. sichuanensis once in September and October were 63.62% and 68.72% 30 days and 60 days after releasing,respectively. The results of regional prevention and control on S. sichuanensis showed that the average control effect was 55.03%.【Conclusion】APF-Ⅰ enhancedtype attractant or CY-1 attractant,with ZM-80 trap hanging higher than the tree canopy had great trapping effect on longhorn beetles. The best control effect on releasing 30000 wasps/ha once in September and October.
