蕃茄植株的天然产物可保护储藏粮食防治某些害虫。就职于美国,堪萨斯,曼哈顿,农业研究局的化学家K.J.克雷默和昆虫学家R.W.比曼,试验了从蕃茄叶提取的2—十三烷酮。他们把各种剂量的2—十三烷酮应用于小麦,然后用8种储粮害虫加害小麦。这种天然杀虫剂对在谷粒内部产卵的谷象、米象和玉米象最为有效;而对在粮粒表面产卵的其它储粮害虫——杂拟谷盗、赤拟谷盗、谷蠹、印度谷螟和粉斑螟,则没有防治效果。K.J.克雷默认为,2——十三烷酮可能渗透到小麦籽粒内部,因而能有效地防
The natural products of tomato plants protect some of the stored pests against pests. Chemist K.J. Kramer and entomologist R.W. Biemann, who worked for the United States, Kansas, Manhattan, and the Agricultural Research Service, tested 2-tridecanone extracted from tomato leaves. They applied various doses of 2-tridecanone to wheat and then harmed wheat with 8 stored grain pests. This natural insecticide is the most effective for grain elephant millet and millet like to lay eggs inside the grain, while other grain-stored pests that lay eggs on the grain surface - Dictyostelium japonicus, Chilo suppressalis and Dipterocarpacealis have no control effect. K. J. Kramer believes that 2-tridecanone may penetrate into the interior of wheat kernels, thus effectively preventing
