Mass TrappingPopillia quadriguttataUsingPopillia japonica(Coleoptera: Scarabaeidae) Pheromone and Floral Lures in Northeastern China

Abstract

Popillia quadriguttata (F.) has caused extensive damage to ≍20 families and 25 species of plants in Asia, especially in China and Korea. Adult feeding causes serious damage to soybean leaves, and larvae develop on the roots of soybean, turf, and horticultural crops. As Japanese beetle (Popillia japonica Newman) lures have been used for trapping P. quadriguttata in a previous study, mass trapping this pest with various densities of the Japanese beetle pheromone, Japonilure, and floral lure, alone and in combination, were carried out during 2012-2013 in a northeastern China soybean field. Mass trapping in 2012 with Japonilure gave the best results with 72 and 75% adult and larval reduction, respectively. In 2013, mass trapping (30 traps per hectare) with Japonilure, floral lure, or the combination resulted in a 93, 70, and 74% reduction of adults trapped, and a 90, 77, and 93% reduction of overwintering larvae, respectively. In addition, field tests showed that almost twice as many beetles approached the lure combination compared with the floral lure alone, and the pheromone residual was ≍80% of the initial dosage after 30 d. Because reduction of overwintering larvae is the most critical parameter indicating treatment efficacy, the results here indicate that the lure or lure combinations can be recommended for use by Chinese soybean farmers.

“…This species is known from a wide area of East Asia, ranging from North Vietnam, China, Taiwan, to Korea (Lee et al, 2007). Records from the Russian Far East are also known (Chen et al, 2014). : Like the related Japanese Beetle (Popillia japonica), this species is known to feed on a broad range of host plants from a broad range of plant families.…”

“…Siberan elm (Ulmus pumila), Japanese wisteria (Wistaria floribunda), Zanthoxylum spp., and corn (Zea mays). Larvae mostly feed on grass roots, though soybeans are also known as hosts (Chen et al, 2014).…”

“…This species is known to damage a variety of commercially valuable plants, both as adults (Chen et al, 2014) and as larvae . In China, this species is considered a major pest of soybean (Glycine max).…”

“…In China, this species is considered a major pest of soybean (Glycine max). Adults cause significant damage to foliage, buds, and stems, while larvae destroy roots (Chen et al, 2014). In Korea, Popillia quadriguttata is a pest of corn (Zea mays) and fruit trees.…”

Japanese beetle lures used alone or combined with structurally related chemicals to trap NE China scarabs (Coleoptera: Scarabaeidae)

“…The most important scarabs in East-Asia are Potosia (Liocola) brevitarsis (Lewis), Popillia quadriguttata (Fabricius), Holotrichia diomphalia Bates et al, and Anomala corpulenta Motschulsky et al (Sang, 1979;Reed et al, 1991;Wang et al, 1999;Lee et al, 2002;Hao and Ren, 2003;Oh et al, 2003;Chen and Li, 2011;Chen et al, 2013bChen et al, , 2014. Scarabs as either adults, larvae, or both may cause damage.…”
