IN VITRO SCREENING FOR INSECTICIDAL ACTIVITY OF CYCLOPENTANESPIRO-5-HYDANTOIN AND ITS FOUR DERIVATIVES AGAINST POTATO TUBER MOTH, PHTHORIMAEA OPERCULELLA ZELLER (LEPIDOPTERA: GELECHIIDAE)

This article presents in vitro evaluation of the insecticidal activity of cyclopentanespiro-5-hydantoin, cyclopentanespiro-5-(2,4-dithiohydantoin), 4-(2-hydroxyethylimino)-cyclopentanespiro-5-(2-thiohydantoin), cyclopentanespiro-5-(2-thiohydantoin) and 1-aminocyclopentanecarboxylic acid on the first instar larvae of the potato tuber moth Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae). It was found out that the 4-(2hydroxyethylimino)-cyclopentanespiro-5-(2-thiohydantoin) manifest a strong effectiveness towards the tested pest.
