Definitions

• the present invention relates to an insecticidal and ovicidal composition and an insecticidal and ovicidal method.
• Patent Document 1 discloses a sterilizing composition comprising a phospholipid and an edible oil.
• Patent Document 2 discloses a miticide composed of animal and vegetable fats and oils and a surfactant.
• Patent Document 3 discloses an insecticidal fungicidal composition comprising a medium-chain fatty acid tridalicelide having 8 to 10 carbon atoms and a surfactant.
• Patent Literature 4 discloses an insecticidal composition comprising a medium-chain fatty acid dalyceride and a toxin produced by Bacillus styrogensis bacteria. Further, Patent Document 5 discloses an insecticidal acaricide containing diglycerin monoolate.
• these conventional insecticidal compositions are mainly intended for controlling adults and larvae, and do not reduce or inhibit the hatching ability of insect pest eggs. Therefore, even if such an insecticidal composition is sprayed to control adults and larvae, the hatching ability of eggs already laid in crops and soil is maintained, and as a result, these eggs will eventually hatch. Therefore, it was necessary to spray the insecticidal composition again because the larvae and adults became larvae.
