Tomato yellow leaf curl virus (TYLCV) has caused severe damage to tomato in Aichi prefecture. So we make cleared the infection cycle of TYLCV and developed the methods of TYLCV on nursery period. 1. Tomato is the most important host. 2. Transmission of TYLCV is caused by Bemisia tabaci B biotype and infection cycle is as indicated below. (1) summer-autumn: TYLCV moves from outdoor tomato to greenhouse tomato - (2) winter: TYLCV passes on greenhouse tomato - (3) spring: TYLCV moves from greenhouse tomato to outdoor tomato - repeat (1) to (3). 3. Insect nets with 0.4 mm mesh inhibited invasion of B. tabaci B biotype and as a result, infection of TYLCV was inhibited. 4. Granules applicated for B. tabaci B biotype prevented infection of TYLCV, but soluble powders, wettable powder and emulsifiable concentrate did not, in this study.
