Abstract

The present study was initiated to find out the insect vector of mulberry dwarf phytoplasma. Among the collected insects from mulberry cultivation region, the sucking insects (Hishimonas sellatus, Bothrogonia japonica and Balclutha punctata) were selected for transmission of mulberry dwarf phytoplasma. Sucking insects, H. sellatus and B. punctata successfully transmitted phytoplasma to healthy seedling mulberry and periwinkle plants by inoculation-feeding. Typical dwarf symptom was observed in mulberry tree, but very slender twigs on stem and formatted small leaves were found on periwinkle plants, which are typical witches' broom symptoms. The phytoplasmas were detected in all samples exception sucking insects B. japonica using phytoplasma universal primer pair R16F2n/R2.

뽕나무 오갈병 파이토플라스마 매개곤충을 알아보기 위하여 뽕나무 재배지에서 채집된 곤충 중 흡즙성 곤충 3 종(Hishimonas sellatus, Bothrogonia japonica and Balclutha punctata)를 선발하였다. 이들 흡즙성 곤충을 뽕나무 이병주에서 흡즙시킨 다음 건전 뽕나무와 일일초로 전반시킨 결과, 마름무늬매미충(H. sellatus)과 B. punctata이 파이토플라스마를 전반하였다. 뽕나무에서는 전형적인 오갈 증상을 보였지만 일일초에서는 가지가 가늘게 늘어지며, 잎은 총생하고 작아지는 빗자루증상이 나타났다. 매개충과 매개전염시킨 뽕나무와 일일초에 대하여 R16F2n/R2 프라이머로 PCR 검정 결과 끝검은말매미충을 제외한 모든 시료에서 파이토플라스마가 검출되었다.
