초록
본 연구는 오동나무천구소병 바이러스의 매개충을 구명하기 위하여 착수했으며, 결과는 다음과 같다. 1) 오동나무천구소병의 이병수에 모여드는 흡수성곤충 중에서 가장 발생이 많았던 곤충은 담배장님노린제며 난, 약충, 성충이 8월 중순부터 10월 하순까지 발생하였다. 2) 담배장님노린재가 오동나무천구소병 바이러스의 매개곤충임이 구명되었다. 3) 담배장님노린재에 의하여 오동나무천구소병 바이러스를 접종한 결과 오동나무유식물에서는 접종 후 20일만에 발병을 보았고 접종 40일만에 오통나무천구소병 특유의 병징이 발현되었다. 4) 접종실험을 통해서 확인된 오동나무천구소병 바이러스의 기주식물은 오동나무 이외에 금잔화 및 나팔꽃이며, 일년감
The present investigation was initiated to find out the possible insect vector of the paulownia witches'-broom virus disease. 1. Among a number of piercing-sucking mouth type insects that were feeding on the witches'-broom infected Paulownia leaves, the tobacco leaf bug, Cyrtopeltis tenuis REUTER, was most abundant. Eggs, nymphs and adults of Cyrtopeltis tenuis were observed from the mid-August through the end of October. 2. It was found that Paulownia witches'-broom virus is transmitted by Cyrotopeltis tenuis. 3. On young Pnulownia plants, first symptom appeared twenty days after exposure to virus-bearing colonies of Cyrtopeltis tenuis. Forty days after exposure to these viruliferous insects, the characteristic symptom of Paulownia witches'-broom was apparent. 4. Paulownia witches' -broom virus was also transmitted by Cyrtopeltis tenuis to calendula and morning glory. No app"rent symptom was observed from tomato, carrot. aster, zinnia, cosmos, soybean and plantago at least until sixty days after exposure to the viruliferous colonies of Cyrtopeltis tenuis. 5. Calendula and morning glory appear to be highly suitable test plants for Paulownia witches'-broom vims because of their relatively short incubation period and distinct symptom appearance.
