Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), is an important quarantine pest of nurseries. Nursery plant movement from P. japonica-infested regions is regulated by the U.S. Domestic Japanese Beetle Harmonization Plan (DJHP), which classifies states by risk categories. Treatments for category 2 states include preharvest soil surface treatment of nursery plants grown in field soil using Discus SC, Marathon (1G or 60 WP), or Flagship (0.22G or 25 WG). In this study, Discus, Marathon 60 WP, or Flagship 0.22G DJHP standards were compared with labeled rates of non-DJHP-approved insecticides, including neonicotinoids clothianidin (Arena 50WDG), generic imidacloprid (Quali-Pro Imidacloprid 2 F T&O Insecticide, Mallet 2 F T&O Insecticide, and Lada 2 F Insecticide), and imidacloprid + bifenthrin (Allectus SC), as well as the anthranilic diamide, chlorantraniliprole (Acelepryn Insecticide). Arena provided 100% P. japonica control in May, June, and July over four test years, but had one larva recovered during August in two of those 4 yr. Acelepryn did not provide DJHP-acceptable P. japonica control. During July, Allectus provided 100% P. japonica control in three of four test years, but had four larvae in one test year. Other treatments tested only during July, which provided 100% P. japonica control, included Discus (five tests); Marathon, Quali-Pro, and Mallet (two tests); and Lada and Flagship (one test). Generic imidacloprid 2 F formulations were equivalent in P. japonica control to DJHP-approved insecticides. Insecticides generally performed poorly on other scarabs or curculionid larvae. The study supports Arena, Allectus, and generic imidacloprid 2 F products as suitable candidates for the DJHP.
日本甲虫，Popillia japonica Newman（鞘翅目：金龟子科），是苗圃的重要检疫害虫。受日本甲虫危害的地区苗圃植物的移动受美国国内日本甲虫协调计划（DJHP）的管制，该计划按风险类别对各州进行分类。对于 2 类地区的处理方法包括在田间土壤中种植的苗圃植物进行收获前土壤表面处理，使用 Discus SC、马拉松（1G 或 60 WP）或 Flagship（0.22G 或 25 WG）。在这项研究中，Discus、马拉松 60 WP 或 Flagship 0.22G DJHP 标准与非 DJHP 批准的杀虫剂标签率进行了比较，包括新烟碱类杀虫剂噻虫嗪（Arena 50WDG）、通用氯虫苯甲酰胺（Quali-Pro 氯虫苯甲酰胺 2 F T&O 杀虫剂、Mallet 2 F T&O 杀虫剂和 Lada 2 F 杀虫剂）和氯虫苯甲酰胺 + 溴氰虫酰胺（Allectus SC），以及邻苯二甲酰胺类杀虫剂氯虫苯甲酰胺（Acelepryn 杀虫剂）。在四年的测试中，Arena 在 5 月、6 月和 7 月提供了 100%的 P. japonica 防治效果，但在其中两年的 8 月有一个幼虫恢复。Acelepryn 没有提供 DJHP 可接受的 P. japonica 防治效果。在 7 月，Allectus 在四年的三次测试中提供了 100%的 P. japonica 防治效果，但在一年的一次测试中有四个幼虫。其他仅在 7 月进行的测试，提供了 100%的 P. japonica 防治效果，包括 Discus（五次测试）；马拉松、Quali-Pro 和 Mallet（两次测试）；以及 Lada 和 Flagship（一次测试）。通用氯虫苯甲酰胺 2 F 制剂在防治 P. japonica 方面与 DJHP 批准的杀虫剂等效。杀虫剂对其他金龟子或象甲幼虫的防治效果通常较差。该研究支持 Arena、Allectus 和通用氯虫苯甲酰胺 2 F 产品作为 DJHP 的合适候选物。
