绿原酸提高舞毒蛾核型多角体病毒(LdNPV)的致病力
Chlorogenic acid enhances the virulence of Lymantria dispar necleopolyhydrovirus (LdNPV)
摘要
Abstract
[Aim] To identify the effects of chlorogenic acid (CA) on the virulence of Lymantria dispar necleopolyhydrovirus (LdNPV) so as to provide information for the prevention and control of the gypsy moth,L.dispar.[Methods] CA + LdNPV and LdNPV were bioassayed using diet plus method,to determine the dose and time response of the 2nd instar larvae of L.dispar.[Results] CA + LdNPV and LdNPV differed significantly in dose and time response when they were tested against the L.dispar larvae.The median lethal concentration (LC50) value of CA + LdNPV to the 2nd instar larvae was 161.8 OBs/μL (the 95% confidence limit was 105.6-235.3OBs/μL),and that of LdNPV was 264.4OBs/ μL (the 95% confidence limit was 178.6-384.0OBs/μL).CA + LdNPV was more virulent than LdNPV against L.dispar larvae.The median lethal time (LT50) value of CA + LdNPV was shorter than that of LdNPV.The LT50 values of CA + LdNPV and LdNPV were 9.9 and 12.3 days,respectively,at the concentration of 590 OBs/μL of LdNPV,and 6.9 and 8.0 days,respectively,at the concentration of 5 900 OBs/μL.The CA lowered the LC50 value and shortened the LT50value of LdNPV against the 2nd instar larvae of L.dispar.[Conclusion] Chlorogenic acid enhances the virulence of LdNPV against the 2nd instar larvae of L.dispar,and its action mechanism needs further study.关键词
