This disclosure relates to the field of molecules having pesticidal utility against pests in Phyla Arthropoda, Mollusca, and Nematoda, processes to produce such molecules, intermediates used in such processes, pesticidal compositions containing such molecules, and processes of using such pesticidal compositions against such pests. These pesticidal compositions may be used, for example, as acaricides, insecticides, miticides, molluscicides, and nematicides. This document discloses molecules having the following formula (“Formula One”).本發明係關於以下領域:具有針對節肢動物門(Arthropoda)、軟體動物門(Mollusca)及線形動物門(Nematoda)中之害蟲之殺蟲效用之分子、產生此類分子之方法、用於此類方法之中間物、含有此類分子之殺蟲組成物及使用此類殺蟲組成物針對此類害蟲之方法。此等殺蟲組成物可例如用作殺蟎劑、殺昆蟲劑、殺壁蟲劑、殺軟體動物劑及殺線蟲劑。此文件揭示具有下式(「式1」)之分子。
