Scarab beetles are agriculturally important worldwide, and as adults or larvae they may cause damage to theleaves, flowers, fruit, and roots of crops. Previous international studies showed that Japanese beetle (Popillia japonica,Newman) lures, and structurally related chemicals, can attract numerous scarabs. Based on those studies,season-long trials in grape, cabbage, corn and soybean fieldswere conducted in 2012–2013 in NE China. Tests determinedthe attractiveness of the Japanese beetle floral lure (phenethyl propionate:eugenol:geraniol, 3:7:3) andsex attractant (Japonilure), alone, combined, or in a mixture with either (Z)-3-hexen-1-ol, anethole = 1-methoxy-4-propenyl benzene or benzyl alcohol, to local Coleoptera. Furthermore, control efficacies based onleaf, ear, and silk damage, as well as reductions of adults on plants, and overwintering larvae, were also determined. Eleven scarab species, and four non-scarab species, were captured. The addition of other chemicals increasedthe attractiveness of the two Japanese beetle lures to scarabs such as Potosia brevitarsis (Lewis),Oxycetonia jecunda Faldermann, Holotrichia diomphalia Bates et al., Popillia quadriguttata (Fabricius), Maladeraverticalis (Fairmaire), and Metabolus impressifrons Fairmaire, and the chrysomelid beetle Chrysomela populi L. The floral lure, and floral lure plus Japonilure baited traps resulted in N80% overwintering larvae and adult reductionsin corn and cabbage fields, whereas the Japonilure traps gave similar results in the soybean fields. This indicatesthat the commercial Japanese beetle lure combination can be recommended for use by the Chinesefarmers in the corn or soybean fields, and that the related chemicals can be used to increase the attractivenessof the Japanese beetle lures.

Popillia quadriguttata (Fabricius), and Protaetia brevitarsis (Lewis) adults were captured with Japanese beetle,Popillia japonica Newman, sex attractant and floral lures at Changchun, China during July–August 2012. The floral lure (phenethyl propionate:eugenol:geraniol, 3:7:3) was attractive to male and female P. quadriguttata (AV: 1.2 ± 0.9; 1.1 ± 0.3; total: 2.3 ± 0.8), and was similar in attraction to the combination of the sex attractant (SA) [(R, Z)-5-(1-decenyl) dihydro-2(3H)-furanone] plus the floral lure formale (1.60 ± 0.2), female (1.30 ± 1.1)and total captures (2.9 ± 3.0). However, the SA alone captured only males in much higher numbers than when combined with the floral lure (10.0 ± 6.4). In a separate earlier test, the greatest number of P. quadriguttata males (12.5 ± 3.0), female (12.2 ± 1.5) and total captures (24.7 ± 2.5) was in yellow, laboratory-made, bottle traps. The floral lure also attracted female Pro. brevitarsis (10.0 ± 3.4),while the SA attracted only fewmale beetles (1.0 ± 0.2). The combination SA + floral lure captured similar females (11.0 ± 2.0) and total (14.2 ± 2.2)Pro. brevitarsis as the floral lure alone. Two butterflies, Colias erate poliographus (Motschulsky) and Pieris rapae (Linnaeus), were also attracted to the floral lure. These studies indicate a potential for replacing pesticides by using the Japanese beetle lures for monitoring and control of several insects in China, and that theywould be useful in monitoring and eradication of two potential scarab pests, P. quadriguttata and Pro. brevitaris, in the United States and Europe

Many Ostrinia furnacalis (Guenée), Asian corn borer, moths inhabit non-corn fields during the second generation, and could fly into corn fields and cause damage. Therefore, during 2013–2014, O. furnacalis pheromone baited Delta traps were distributed to investigate captures in different host habitats, such as corn fields preceded by various crops, or soybean fields neighboring corn. Months captured from various host fields were evaluated in the laboratory for fecundity, female longevity and mating behavior. The sex ratio of females to males from black light baited water traps deployed in soybean and corn fields was also compared. More males were found in the soybean fields, and catches decreased in traps going fromthe field center toward a corn field. This indicates that males in soybeans were not moving into nearby corn fields. No significant differences were noted in sex ratios, life span and fecundity of females between locations. Therefore the O. furnacalis females apparently lay eggs in their initial habitat but may move to soybeans for mating.
