摘要

在这项研究中，我们旨在调查五种不同的市售精油的效果；芦荟、琉璃苣、可可、栗子和荨麻籽油对烟粉虱及其重要天敌——台湾飞蛾、埃雷米库斯玫瑰和佐尔纳罗维奇、大花斑蝶、细纹海蝶和金龟子纤维——的卵、若虫和蛹期的抗性。这项研究于2021年在土耳其布尔萨乌卢达大学的实验室条件下进行。精油溶液以%0.125、0.25和0.5的剂量施用，并且在施用精油24、48和72小时后观察到死亡率。结果表明，受植物油影响最大的昆虫种类分别是捕食者、粉虱的未成熟阶段（卵、若虫和蛹）和寄生蜂。24小时后，硼砂和七叶树油对捕食性成虫表现出高效果（100%）。在试验中，确定所有的N.tenuis和M.pygmaeus成虫在48小时后死亡。烟粉虱的卵期、若虫期和蛹期分别受到植物油的影响最大。可可油对烟粉蝶卵和蛹期的影响最大，死亡率为100%。此外，七叶树油对烟粉虱若虫期的影响最大，72小时后死亡率为100%。在试验中，寄生蛹被发现是受影响最小的个体。芦荟油是实验中效果最差的精油。芦荟油对烟粉虱、金翅虫、福尔摩沙和eremicus的卵和若虫期均有影响，死亡率分别为53.33%、46%、53%、46%和36%。在试验中，栗子油和可可油对烟粉虱的未成熟阶段（卵、若虫和蛹）和所有捕食者成虫（P.pygmaeus、N.tenuis、O.laevigatus）都是有害的，但对寄生蜂的危害较小

Toxic effects of essential oils against Bemisia tabaci (Gennadius, 1889) (Hemiptera: Aleyrodidae) and its certain important natural enemies

In this study, we aimed to investigate the effects of five different commercially available essential oils; aloe vera, borage, cacao, horse chestnut and nettle seed oils against egg, nymphal and pupal stages of Bemisia tabaci Gennadius and its important natural enemies namely, Encarsia formosa Gahan, Eretmocerus eremicus Rose and Zolnerowich, Macrolophus pygmaeus Rambur, Nesidiocoris tenuis Reuter, and Orius laevigatus Fiber. This study was conducted under laboratory conditions in 2021 at Bursa Uludag University, Turkey. The essential oil solutions were applied at %0.125, 0.25 and 0.5 doses and mortality rates were noted after 24, 48 and 72 hours of essential oils application. As a result, it was determined that the insect species most affected by the plant oils were the predators, the immature stages (egg, nymphal and pupal) of whitefly and the parasitoid species, respectively. Borage and horse chestnut oils showed high effects (100%) on predatory adults after 24 hours. It was determined that all N. tenuis and M. pygmaeus adults died after 48 hours in the trial. The egg, nymphal and pupal stages of B. tabaci were most affected by plant oils, respectively. B. tabaci eggs and pupal stages were the most affected from cacao oil with a mortality rate of 100%. Moreover, nymphal stage of B. tabaci was the most affected by horse chestnut oil with a mortality rate of 100% after 72 hours. Parasitized pupae were found to be the least affected individuals in the trial. Aloe vera oil was the least effective essential oil in the experiment. Eggs and nymphal stages of B. tabaci, O. laevigatus, E. formosa and E. eremicus were affected by aloe vera oil with mortality rates of 53.33%, 46%, 53%, 46% and 36%, respectively. Horse chestnut and cacao oils were harmful to the immature stages (egg, nymphal and pupal) of B. tabaci and all predator adults (M. pygmaeus, N. tenuis, O. laevigatus), but they had slightly harmful on parasitoid species in the experiment
