In the new study , foy and colleagues wanted to know whether ivermectin 's insecticidal effect translated into fewer infectious mosquitoes , which in turn could slow the spread of malaria .
The study provide the theoretical proofs of the exploitation and utilization of insecticidal plants in heilongjing province , simulated synthesizing of biological pesticides .
研究结果为黑龙江杀虫植物的开发与利用,以及生物农药的模拟合成提供理论依据。
The use of arthropod pathogens like entomopathogenic fungi ( fungi that kill insects ) , diatomaceous earth , insecticidal soaps and botanical insecticides are allowed under the standards .
The paper summarizes the research advances of cuminum cyminum related to chemical composition , medical treatments , foods and agriculture with emphasis on its insecticidal 1 and anti bacterial or fungal effects so as to provide the basis for its pesticide research and comprehensive exploitation .
Thuringiensis . Only by the presence of crystal protein , and is studied systematically because of insecticidal activity of crystal protein . In the aper , we reviewed genetic diversity of insecticidal crystal protein and its genotype by analysing the type of crystal protein , cry gene and plasmid bome cry gene and their distribution inb .
The paper reviews the insect-resistant mechanisms , classifications and insect-resistant spec-trams of several main insect-resistant genes , such as bt insecticidal crystal protein cpti gene etc. the applications in vegetable breeding are also reviewed .
