OVICIDAL AGENT

To provide an ovicidal agent that solves the problem in which, to an egg mass covered by a breathable membrane having scales and egg capsules, a liquid-state agent is less effective and there are cases where the agent remains at the sprayed area after the spraying of the agent.SOLUTION: The ovicidal agent that uses allyl isothiocyanate as an active ingredient and kills egg masses or eggs that are surrounded by a breathable membrane is highly volatile and the agent does not remain in the sprayed area. Further, by filling the inside of the egg mass covered with a breathable membrane with the active ingredient, an ovicidal effect (hatching inhibiting effect) can be exerted.SELECTED DRAWING: None 【課題】鱗毛や卵嚢を有する通気性を有する膜に覆われている卵塊には、液体状の薬剤は効果を発揮しにくく、また、薬剤を散布後に散布箇所に薬剤が残留する場合があった。【解決手段】アリルイソチオシアネートを有効成分とし、周囲を通気性膜で覆われた卵塊若しくは卵を死滅させる殺卵剤は、揮発性が高く、散布箇所に薬剤が残留することがない。また、通気性膜で覆われた卵塊の内部を有効成分充満状態にすることで、殺卵効果（孵化抑制効果）を発揮させることができる。【選択図】なし
