Biological Activity of Pinellia ternata with Various Extraction against Aphis glycines and Preliminary Screening of Activity Concentration;

Contacting Activity against Aphis glycines of Ethanol Extraction from Three Gentiana in Mountain Changbai

Contacting death and antifeeding against Aphis glycines of various extraction from the bulbs of Typhonium giganteum Engler were studied through Uniform Design.

The number change laws of soybean aphid and their natural enemies per 100 plants were investigated in order to extend the prevention and control scope of soybean aphid.

To investigate the effect of pathogenicity of Paecilomyces cicadae (PC) to aphis medicnginis koch, the insecticidal mortality of the 8 strains of PC were tested.

The Behavioral Responses of Myzus persicae, Aphis gossypii, and Aphis glycines to Organic Solvents;

The spatial distribution pattern and sampling technique of the soybean aphid,Aphis glycines Matsmura in vegetable soybean field;

Cloning and sequencing of cytochrome oxidase Ⅱ gene of Aphis glycines and its application in detecting natural enemies;

The susceptibility of Aphis glycines Matsumura to 2.

of hungry treatment to Leis axyridis for twenty-four hours,we analyzed the number variety of two Aphis in different density, and concludedthat the fitted model was Holling equation and the control ability of letsaxyrids to Aphis glycines Matsumura was stronger than that of Leis axyridis toRhojalosighum maides.

The soybean aphid (Aphis glycines Matsumura ) is one of the main pests of seedling stage of soybean, because soybean aphid produce resistance to chemical pesticide, people enhance consciousness to environmental protection at the same time, the biological control of the soybean aphid is more and more attention to by people.
