Sivrisinek larva öldürücülerin hedef ve hedef dışı canlılara etkisi

Abstract

Calismada son yillarda yogun olarak kullanilan larvasitlerin hedef ve hedef disi canlilara dogal ekosistemde ve laboratuvar kosullarda etkisi incelenmistir. Larvasitlerin uygulama dozunda larvalar karsi etkin oldugu ancak gerritlere etkisinin olmadigi gozlenmistir. Ancak fitoplanktonlara ve zooplanktonlarin sayisal dagilimina olumlu ve olumsuz sonuclara rastlanmistir.Gambusia affinis adli sivrisinek baliklarina ise larvasit kullanim dozunda olumsuz bir etki gorulmemistir. Dimilin, Temephos, Vectolex, Fenthion, Spinosad, Altosid ve Sumilarv larvasitleri fitoplanktonik ve zooplanktonik organizmalarin yogunlugunda azalmalar meydana getirmistir. Vectobac’ta ise yogunluk azalisinin daha az oldugu tesbit edilmistir.AbstractIn the study, effects of most commonly used larvacides on the target and non-target organisms in natural ecosystems and laboratory conditions were investigated. Although the larvacides were found effective on the larvae, they were not effective on the gerrits. However, no positive or negative effect was determined on the phytoplankton and numerical distribution of zooplankton. Also, negative effect was not seen on the mosquito fishes, called Gambusia affinis. In the study it was observed that Dimilin, Temephos, Vectolex, Fenthion, Spinosad, Altosid and Sumilarv had decreased the organismal density of phytoplankton and zooplankton. It was also observed that Vectobac had decreased the organismal density of phytoplankton and zooplankton lesser than the other larvacides.
