杀虫双是我国自行开发的一个农药新品种,最近一、二年开始用于大田防治。各地试验表明,杀虫双防治水稻螟虫、稻纵卷叶螟、稻蓟马等效果显著,是取代杀虫脒的优良杀虫剂之一。杀虫双(双钠盐)、巴丹(杀螟丹)、易卫杀(杀螟环)等,同为沙蚕毒素衍生物。1934年日本人新田从海中环行动物——沙蚕体内分离出一种叫沙蚕毒素的物质,1962年桥本等确定了沙蚕毒素的化学结构式,随后有很多沙蚕毒素衍生物相续被合成出来,这是仿生学在农业上应用的典 Insecticidal double is our own development of a new pesticide species, the last one or two years for field control. Experiments show that pesticide and pest control rice stem borer, rice leaf roller, rice thrips and other significant effect, is to replace the chlordimeform one of the excellent insecticides. Insecticidal double (double sodium salt), Bataan (Cartap), easy to kill Wei (Diaozhong Central), the same Nereid toxin derivatives. In 1934, the Japanese Nantian isolated a substance of Nereis of venom from the sea circadian organism - Nereis. Hashimoto’s toxin was identified by Hashimoto et al. In 1962, followed by many neotoxin derivatives Was synthesized, which is a bionic application of agriculture in the Code
