阅读文字材料,按要求回答36-40题。 长期大量使用化学农药使得抗药害虫种类不断增加,且抗药性也越来越厉害。今天要杀死这些抗药害虫,必须将剂量增加成千上万倍,既增加生产成本,又会杀死害虫天敌,造成农作物害虫频频成灾。尤为严重的是,大量使用化学农药,会加剧环境污染,损害人类身体健康。据联合国环境规划署统计,全世界每年有200万人发生农药急性中毒,其中有四万人丧生。而病得不清不楚,死得不明不白的慢性中毒者,数量无法统计。 面对化学农药长期滥施造成的一系列严重问题,各国科学家从加紧研究有毒植物和推广应用植物农药等方面寻找出路。近年来,植物农药的研制已取得了一定成果。植物农药又叫生物农药,是利用有毒植物中的多种杀虫成分,经过提炼后生产的农药。与化学农药比较,植物农药有着突出的优点。 由于它们的杀虫有效成分为天然物质。而不是人工合成的化学物质。因此,施用后较易分解为无毒物质。对环境无污染。由于植物杀虫剂杀虫成分的多元化,就使害虫较难产生抗药性。这同病菌对中药混合物煎剂较之于单质的抗菌素更难______的道理一样。植物农药有益生物(即害虫天敌)的安全。根据试验,使用我国研制的鱼藤菊酯植物杀虫剂的常用剂量喷施,对蔬菜头号害虫萝卜蚜的防治效果达到99.85%。而对蚜虫天敌瓢虫的杀伤率仅为11.58%;对照使用的化学杀虫剂乐果乳油的两个指标分别为71.5%和28.54%。 此外,有毒植物可以大量种植,而且开发费用也较低。我国已发现的有毒植物达一万多种,它们当中大都具有杀虫抑菌作用,较有价值的杀虫植物大概有五类:对昆虫有强烈驱赶作用的,如丁香、茴香;对作物真菌病和病毒病有疗效的,如大黄、烟草;可提炼使昆虫有强烈拒食作用的天然物质的,如川楝、花椒;能影响昆虫激素平衡的,如万寿菊、香茅;使昆虫绝育的,如喜树硷、姜油等。 下列说法不符合原文意思的一项是( )。
A. 植物农药对害虫的防治效果是化学农药所不及的
B. 人工合成的化学农药杀虫成分单一化,因而害虫容易产生抗药性
C. 植物农药防治农作物虫害的原理主要是驱赶害虫和破坏抑制害虫的生理机能
D. 我国已发现的有毒植物都具有杀虫抑菌作用
