Abstract

This study was conducted to investigate percentage of parasitism and control effect of Liriomyza trifolii by Hemiptarsenus zilahisebessi on tomato. Percentages of parasitism on L. trifolii larva by ectopatasitoids war e 26∼45% Among them the parasitism by H. zilahisebessi was highest as 47∼75% in tomato. The parasitoids preferred 1 st to 3rd instar of host larvae. In laboratory test, the parasitoids showed high parasitism on 3rd instar larvae of host by 89.8∼93.1% when the female parasitoids were introduced by the ratios of 1 : 10, 1 : 20, and 1 : 30. In field test, 3 or 5 female parasitoids were introduced per plant. In the case, the parasitism increased to 80% 4 weeks after introduction of the parasitoids. This increased parasitism was resulted from density reduction of the host larvae There were no significant differences in parasitism, density of alive host, and percentage of damaged leaf between inoculation density.

토마토에서 Hemiptarsenus zilahisebessi에 의한 아메리카잎굴파리의 밀도억제 효과를 실내와 온실에서 확인하였다. 토마토에서 외부기생봉류에 의한 아메리카잎굴파리의 기생율은 26~45%이었으며 이 중 H. zilahisebessi의 비율은 47~75%이었다 암컷 성충의 기주체액섭취율이 기주 1령유충과 3령유충에서 각각 40.4%와 37.9%이었으나 1령과 3령유충을 동시에 접종할 때 1령보다는 3령유충을 주로 체액섭취하였다 사육실에서 H. zilahisebessi 암컷과 기주 3령유충을 1 : 10, 1 : 20, 1 : 30으로 접종시 기주 시망율은 각각 93.1%, 92.1%, 89.8% 이었다. 토마토 포장에서 주당 암컷 3마리, 5마리를 접종한 결과 접종 4주째에 80%정도의 기생율을 나타냈으며 시간이 경과됨에 따라 아메리카잎굴파리의 유충밀도도 감소되는 경향을 보였다. 피해엽률 또한 접종 4주후부터 무접종구에 비하여 낮아지는 경향을 보였다. 그러나 접종밀도에 따른 기생을, 기주 유충 생충율 및 피해엽률의 차이는 없었다.
