,a Chinese endemic plant,showed photo-activated insecticidal activity,the corrected mortality of irradiated insects incubated with 500 μg/mL methanol extract was 100% 24 h after irradiation,whereas the non-irradiated insects appear.

According to the fact that diphenylcarbazide could be oxidized to red product by reactive oxygen species,a new screening method for photo-activated insecticidal plants was established,which was perationally simpler,more rapid and sensitive than the conventional bioassay.

Synthesis and insecticidal activity of new bis-benzoylphenylurea compounds(Ⅱ);

Study on insecticidal activity and extraction of effective component from several nature plants;

Synthesis and insecticidal activity of 2- (p-chlorophenyl) pyrrole-3-carbonitriles;

The(developments) of its pesticidal bioactivities such as plant growth regulation,fungicidal activity,pesticidal activity were presented.

It was revealed that its pesticidal activity had strong lethal effects on several harmful insects, such as some species of Abraxas, Setora and .

The results showed that the insecticide activity of Avermectin and diflubenzuron is higher than kurarinon to this insect,and the co-toxicity coefficient of the mixture of Avermectin and kurarinon is 168.

The results showed that the insecticide activity of Avermectin and Imidacloprid was higher than kurarinon to this insect, and the co-toxicity coefficient of the mixture of Avermectin and Imidacloprid were 244.
