| Abstract: | Toxic effects of 11 insecticides to ladybug were bioassayed by spraying in the laboratory. The results showed that the routine OP insecticides toxicities of omethoate,parathion-methyl, monocrotophos,phoxim were strong to ladybug,toxicities of cypermethrin,pirimicarb and propargite were middle;natural products insecticides toosendanin,nicotin serize and oleic nicotin-cypermethrin mixture toxicities were weak.Toxicity of there insecticides were stronger to ladybug larva than to its adult. |
