Abstract

The granulate ambrosia beetle, Xylosandrus crassiusculus (Motschulsky), and the black stem borer, Xylosandrus germanus (Blandford) are important pests in ornamental nurseries in the eastern USA. These beetles are managed mainly using preventative trunk applications of pyrethroids, such as permethrin or bifenthrin when females typically fly out of woodlots and attack young trees in the spring. Verbenone and methyl salicylate are potential phytochemicals reported as repellants but not completely validated in ornamental nurseries for ambrosia beetle management as an alternative option. Thus, this study aimed to compare the efficacy of verbenone alone or with methyl salicylate and permethrin on ambrosia beetle attacks. In 2023 and 2024, a study was conducted where verbenone (with methyl salicylate) and permethrin were combined with 10% and 50% ethanol-infused maple bolts. Verbenone alone or combined with methyl salicylate did not reduce ambrosia beetle attacks on bolts compared to permethrin. Permethrin was effective in reducing ambrosia beetle attacks on bolts. This suggests that permethrin is still the best option to prevent ambrosia beetle attacks on young trees in ornamental nurseries.

马鞭草酮、水杨酸甲酯和氯菊酯在观赏苗圃中对夜蛾攻击的影响比较。
木沙虫(Xylosandrus crassiusculus, Motschulsky)和黑茎螟(Xylosandrus germanus, Blandford)是美国东部观赏苗圃的重要害虫。这些甲虫的防治主要是在树干上预防性喷洒拟除虫菊酯,如氯菊酯或联苯菊酯,因为雌性甲虫通常会在春天飞出林地,攻击小树。据报道,马鞭草酮和水杨酸甲酯是潜在的植物化学物质,但作为一种替代选择,尚未在观赏苗圃中得到完全验证。因此,本研究旨在比较马鞭草酮单独或与水杨酸甲酯和氯菊酯联合使用对赤蛾甲虫攻击的效果。在2023年和2024年进行的一项研究中,马鞭草酮(含水杨酸甲酯)和氯菊酯与10%和50%乙醇注入的枫螺混合使用。与氯菊酯相比,马鞭草酮单独使用或与水杨酸甲酯联合使用均不能减少凤头虫对螺栓的攻击。氯菊酯能有效降低赤蛾对螺栓的侵害。这表明,在观赏苗圃中,氯菊酯仍然是防止赤蛾甲虫袭击幼树的最佳选择。

期刊介绍: The Journal of Insect Science was founded with support from the University of Arizona library in 2001 by Dr. Henry Hagedorn, who served as editor-in-chief until his death in January 2014. The Entomological Society of America was very pleased to add the Journal of Insect Science to its publishing portfolio in 2014. The fully open access journal publishes papers in all aspects of the biology of insects and other arthropods from the molecular to the ecological, and their agricultural and medical impact.
