摘要：

Comparative toxic effects of pyrethroid (deltamethrin 0.25%) and tetranortriterpenoids (neem formulation SDS 25%) were determined in laboratory against Cyprinus carpio (common carp). It was round that LC50 of deltamethrin was 21 ppm and LC50 of tetranortriterpenoids was 250 ppm i.e. deltamethrin was found more toxic than tetranortriterpenoids (SDS) as it caused 100% mortality at 27.5 ppm, whereas SDS caused 95% mortality at 400 ppm.
