Insecticidal Activity of the Eco-Friendly Organic Materials on Gelechiidae (Ilseopsis parki Povolny

초록

)
Background : Insect pests damages are increasing on the field of Lycium chinense under eco-friendly organic management and especially, pest damage of Gelechiidae (Ilseopsis parki Povolny) is serious. Currently, various eco-friendly organic materials are registered, but insecticidal activity against Gelechiidae was not verified. Therefore, this experiment was carried out to select eco-friendly organic materials showing insecticidal activity in Gelechiidae. Methods and Results : To test insecticidal activity, the Gelechiidae lavas were collected from the field and Nine eco-friendly organic materials were collected from the market. method. The insecticidal activity assay method was, putting Gelechiidae lavas on the 90mm petridish then water-diluted eco-friendly organic materials were sprayed onto the laver. Result of insecticidal activity was observed with a microscope 10 minutes, 2 hours and 18 hours after the treatment. Microscopic observation results, insecticidal activity was shown only in 5 out of 9 materials. Conclusion : As a result, Insecticidal activity against Gelechiidae was not effective in all tested materials, but the 5 eco-friendly organic materials showed the same effect in repeated experiments. In this study, we selected 5 materials out of 9 eco-friendly organic materials against Gelechiidae, then future studies are planned to select the most suitable materials by field testing the 5 eco-friendly organic materials.
