Abstract

This studies by treatment of 25 individual adults of O. laevigatus and Banker plant with different number of eggs of O. laevigatus were conducted to develop new biological control of the western flower thrips (WFT) in chrysanthemum house. In this work, a treatment of 25 individual adults of O. laevigatus, Banker plant with different number of eggs of O. laevigatus and mixed treatment were applied. Initial WFT density per plant were 5 individuals. WFT density was measured every 7days after treatment for 7 weeks. Biological control of WFT by 25 individual adults of O. laevigatus and Banker plant with 25 eggs of O. laevigatus were applied 1 time and resulted in the high control value of thrips 91.8%. The population of WFT was kept under the economic threshold level (1 individual per plant). For the last three years we developed new banker plant system. This system is being developed to improve biological control of WFT on chrysanthemums.

시설국화에서 꽃노랑총채벌레를 친환경적으로 방제하기 위하여 미끌애꽃노린재와 미끌애꽃노린재 뱅커플랜트를 적용하여 7주 동안 천적의 분포 및 해충의 밀도변동을 조사하였다. 시설국화에서 천적의 방사방법 및 방사량에 따른 해충의 밀도 억제 효과를 검증하고자 천적 단독 처리, 뱅커플랜트 단독 처리 I, II, 천적과 뱅커플랜트 혼합 처리 I, II의 시험구를 설정하였다. 천적과 뱅커플랜트를 혼합 적용하여 처리한 곳이 국화 1주당 꽃노랑총채벌레 1마리 이하로 70마리까지 증가한 무처리구에 비해 밀도 억제 효과가 가장 뛰어났다. 이 처리구에서 91.8%의 꽃노랑총채벌레에 대한 방제가를 보였으며 친환경자재 처리구에 비해 5.8배, 천적 단독 처리구에 비해 1.4배의 해충 방제 효과가 있어 시설재배 국화에서 천적과 뱅커플랜트 혼합 적용의 꽃노랑총채벌레 방제 가능성을 확인하였다.
