Biocidal Effect of Deltametrin Against Thaumetopoea Wilkinsoni Tams, 1924 (Lepidoptera: Notodontidae) in Laboratory Conditions

Abstract

This study was carried out to determine the effect of deltamethrin, which is used against some urban pests, on Thaumetopoea wilkinsoni Tams, 1924 under laboratory conditions. The recommended dose of the biocidal against urban pests (60 ml / 10 liters of water), half dose (30 ml / 10 liters of water) and quarter dose (15 ml / 10 liters of water) were used in the study. At the highest dose of the biocidal, on day 1 (60 ml / 10 liters of water) 77.5% mortality was detected, three days showed 82.50% and five days showed 90% mortality. On day 5 of the study, the LD50 value for T. wilkinsoni was 34.03 and LD90 56,21. As a result of the study, it has been determined that the Exdel 5 SC (Deltamethrin) has a biocidal effect for pine processionary moth.
