Efficiency evaluation of some insecticides in protecting sycamore wood from termite infestation microcerotermes diversus silv.(Isoptra:Termitidae)

Abstract

The toxicity study results of Chemosbane %40.8 E.C, Chlorovite %48 E.C, Demone %25.3 E.C, Dursbane %40.8 E.C, Rigente %50 Sc, and Tirmedor %25 E.C, Insecticides on termite workers (Microcerotermes diversus Silv.) revealed that tirmedor and Chlorovite exhibt a superior toxicity effect on termite in comparison with the other tested insecticides and their LC50 reached 0.0031, 0.0035 respectively. Tirmedor also showed a high efficiency in protecting sycamore wood (Platanus orientalis) for 15 months from termite infestation with %80 mortality in termite workers. The expansion of wood protection period from termite infestation achieved by increasing insecticides concentration and using wood imersion method instead of wood spraying method.
