Özet
Ham neem yaprağı özütünün karasineğe (Musca domestica L.) karşı toksisitesi DDVP’nin (Dichlorvos) toksisitesiyle karşılaştırılmıştır. Neem yaprağı özütü 5; 10; 20; 40; 80µg/karasinek dozlarında, DDVP ise 0.1, 0.2, 0.4, 0.8, 1.6 µg/karasinek dozlarında uygulanmıştır. Probit analizi yöntemiyle hesaplanan öldürücü doz değerleri neem özütü için LD50= 8.4 µg/karasinek, LD90= 169.8 µg/karasinek; DDVP için LD50= 0.44, LD90= 3.58 µg/karasinek olarak tespit edilmiştir.
Abstract
Toxicity of neem extract in comparison with DDVP (Dichlorvos) was determined against the housefly ( Musca domestica L). Neem leaf extract was applied at 5, 10, 20, 40 and 80 microgram/fly and DDVP was treated in 0.1, 0.2, 0.4, 0.8 and 1.6 microgram/fly doses. Lethal dose values were calculated with probit analysis and $LD_ {50}$ and $LD_ {90}$ values were found to be 8.4 and 169.8 ug/fly of neem extract respectively, whereas, values of 0.44 and 3.58 ug/fly of DDVP were found for $LD_ {50}$ and $LD_ {90}$ against house flies.
