摘要
Hyoscyamus 尼日尔 L。(Solanaceae ) 并且 Hypericum calycinum L。(Hypericaceae ) 在 flowering 阶段期间在土耳其从二省囊和安卡拉是镇定的。从 H 获得的摘录。尼日尔和 H。calycinum 作为 acaricidal 杀虫剂对 two-spotted 螨被测试。生物鉴定实验也就是用二个不同方法在实验室条件下面被执行，叶圆盘蘸并且直接的叶喷洒。Two-spotted 螨用 Phaseolus vulgaris L 在 insectary 被饲养。(Fabaceae ) 。在蘸方法的叶， H。尼日尔摘录为 87.13% 的幼虫并且为 81.66% 的成年人导致了有效调整死亡。为 H。calycinum 为幼虫和成年人的调整死亡在最高的集中分别地是 77.77% 和 85.97% 。在幼虫的舞台， LC <sub>50</sub> 价值是分别地蘸并且喷洒方法的 5.47 w/v 和 3.32 w/v。另外，成年舞台， LC <sub>50</sub> 价值在两个方法是 1.17 w/v 和 3.56 w/v，这被决定。为喷洒方法的叶。H。尼日尔导致了一调整证明对幼虫和成年人死亡率的效果分别地是 95% 和 91% 。然而， H。calycinum 死亡百分比在 12% 集中是 80% 和 87% ，与 LC <sub>50 </sub > 在蘸的 9.62 w/v 和 2.13 w/v 的价值方法。在除了鸡蛋上的死亡效果的这研究，复制也被调查。每集中证明对待的女性与未经治疗的女性相比生了更少的鸡蛋。
Hyoscyamus niger L. （Solanaceae） and Hypericum calycinum L. （Hypericaceae） were collected from two provinces Bursa and Ankara in Turkey during flowering stages. Extracts obtained from H. niger and H. calycinum were tested against two-spotted mite as an acaricidal pesticide. Bioassay experiments were carried out under laboratory conditions using two different methods namely, leaf disc dipping and direct leaf spraying. Two-spotted mite was reared in insectary using Phaseolus vulgaris L. （Fabaceae）. In the leaf dipping method, H. niger extract resulted in an effective adjusted mortality for larvae of 87.13% and for adults of 81.66%. For H. calycinum the adjusted mortality for larvae and adults was 77.77% and 85.97% respectively at the highest concentration. In larval stage, LCs0 values were 5.47 w/v and 3.32 w/v dipping and spraying method respectively. In addition, adult stage, it was determined that LCs0 values were 1.17 w/v and 3.56 w/v in both methods. For leaf spraying method. H. niger resulted in an adjusted showed an effect against larvae and adults mortality rate was 95% and 91% respectively. However, H. calycinum mortality percentage was 80% and 87% at 12% concentration, with LC50 values of 9.62 w/v and 2.13 w/v in dipping method. In this research apart from mortality effects on egg, reproduction was also investigated. Each concentration showed that treated females laid less eggs compared to the untreated females.
