 茶の有機または無農薬栽培実践者に対して,被害が問題となる害虫を聞き取り調査したところ,チャノミドリヒメヨコバイEmpoasca onukii Matsuda防除の必要性が高かった。そこで,防虫ネットによる防除試験を行った結果,目合い 1.0mmのネットを中切りや浅刈り後,すぐに直がけすることで被害が軽減された。また,このような防虫ネットの直がけは,チャノミドリヒメヨコバイだけでなくチャノホソガCaloptilia theivora (Walsingham),ツマグロアオカスミカメLygocoris spinolae(Meyer-Dür)に対しても高い防除効果が認められた。

For farmers for organic forming and non-pesticide cultivation of the tea, the necessity of controlling Tea Green Leafhopper Empoasca onukii Matsuda was high, when the pests in which the damage became a problem was investigated by questioning. Then, the damage was reduced 1.0mm hole size insect-proof nets by immediately direct covering after the medium pruning or light trimming of canopy, as a result of the control test insect-proof nets. And, there were not only Tea Green Leafhopper but also high control effect against tea pests by direct covering tea plants with insect-proof nets, for Tea Leaf Roller Caloptilia theivora(Walsingham) and Pale Green Plant Bug Lygocoris spinolae(Meyer-Dür).
