本试验比较了九种天然植物芳香油和二种芳香油单一成份对杂拟谷盗成虫的熏杀效果,测定了杂拟谷盗、玉米象、谷蠹、锯谷盗、长角扁谷盗、锈赤扁谷盗等六种仓虫对植物芳香油的敏感性,考察了温度、浓度和熏杀时间对杂拟谷盗各虫态死亡率的综合效应。结果表明:1、3、4、11、14号等五种天然植物芳香油对杂拟谷盗成虫的致死效果最好,六种仓虫的敏感性大小顺序是:长角扁谷盗>锈赤局谷盗>杂拟谷盗>谷蠹>锯谷盗>玉米象。在22——32℃范围内,温度对芳香油杀虫作用的影响不明显,从1/10万到1/万,杀虫效果随浓度增加而增加;对不同虫态,以蛹的敏感性最弱,成虫、幼虫都较强,植物芳香油的单一成份α-蒎烯对人畜安全,价格便宜,又能人工合成,是很有生命力的植物性杀虫剂
This experiment compared the fumigant effects of nine natural plant aromatic oils and two aromatic oil single components on the adults of Trifolium pratense, and determined the effects of miscellaneous grains, corn gourd, , Rust Cotyledons and other six species of caterpillars on plant aromatic oil sensitivity, investigated the temperature, concentration and time of smoldering on the miscellaneous grains in the overall mortality of the symbiotic effect. The results showed that five natural plant aromatic oils (1,3,4,11,14 and so on) had the best lethal effect on the adults of T. marmosetus. The order of sensitivity of six species of C. elegans was as follows: Red Army Valley Pirates> Miscellaneous Turpan Valley> Rhododendron> Saw Valley Pi> Corn elephant. In the range of 22 - 32 ℃, the effect of temperature on the insecticidal effect of aromatic oil was not obvious, from 1/100 to 1/10000, the insecticidal effect increased with increasing concentration; for different insect states, the pupae sensitivity The weakest, adults, larvae are strong, plant aromatic oil, a single component of α-pinene on human and animal safety, cheap, but also synthetic, is a very viable botanical insecticide
