Abstract
The mortality was tested to organic control materials to the E. maslovskii adults by the dipping method in laboratory. As the result, in 2014, the extracts of Neem I was not shown control effect by 10.2% control efficacy to E. maslovskii adults in laboratory. The extract of Sophora flavescens roots was shown 84.7% mortality. And other 5 materials were shown 100% insecticidal activity to the adults in laboratory. I n 2015, Plant extract+pyrolignous acid Matrine 0.45% and Plant extract Matrine 0.5+paraffin oil 8% were shown 100% and 94.6% control efficacy, respectively. In the Japanese apricot orchards, the fruit damage rate was low on spray at 21th April in Daap, Gwangyang city, and 8th May Hwangjeon, Suncheon city in Jeonnam province in 2014. The fruit damage rate differed from spray timing and materials, but it was considered that the control of E. maslovskii should be in late April to early May. Otherwise, in 2015, the fruit damage was significantly low in late April spray in Daap, but no significant was in between one spray at 21th, 27th April and 2 spray that days. Meanwhile, the control effect was better 2 times spray of the days in Hwangjeon, Suncheon city in Jeonnam province. Therefore, in organic Japanese apricot, the use of insecticidal materials recommended to control over twice spay in from meddle to late April.
