Control of Ostrinia furnacalis Differed between Field Release Methods of Trichogramma dendrolimi
摘要
Abstract
To improve the control of Ostrinia furnacalis showing new situation of occurrence and damage in Jilin Province,we conducted tests for optimal field release methods for Trichogramma dendrolimi from 2018 to 2020.The field tests showed significant differences in the control afforded by the Trichogramma released by different methods.Either increasing the number or the amount of Trichogramma release improved the control efficiency.When T.dendrolimi was used continuously to control the first and second generations of O.furnacalis,the control efficiency reached the highest of 79.32%.It is recommended that for control of the first generation of O.furnacalis,15000 T.dendrolimi wasps be released in three times at quota of 3000,7000,and 5000 wasps,respectively,at 2 release points each time per 667 m2.For the second generation of O.furnacalis,10000 T.dendrolimi wasps are released once at 2 release points per 667 m2.In our practice,T.dendrolimi was released by plant protection UAV in an area of 1334 hm2 for control of O.furnacalis,the control efficiency reached 76.36%-81.23%.关键词
