Studies on the Relationships between the Selective Toxicity of Celangulin V and Two Kinds of Detoxifying Enzymes of Insect;

Immunolocalization of the Celangulin V Receptor and the Construction of cDNA Library of the Midgut of Oriental Armyworm, Mythimna Separata Walker (Lepidoptera: Notuidae);

The studies on the kinds of storage protein,molecular weight,subunit molecular weight,compositions and contents of amino acid of storage protein,and the sublethal effects caused by celangulin V on the contents of storage protein and the mounts of laid eggs by the adults had been carried out by means of PAGE,SDS-PAGE,Western blot and amino acid analyzer.

In order to determine the content of angulatin A in angulatin products and control the quality of products,angulatin A was prepared with a series of steps,including extraction with 95 % ethanol,segregation by silica gel column,decolourization with active carbon,and separation with preparative high performance liquid chromatography.
