Mass trapping to reduce an isolated population of Japanese beetles (Popillia japonica) was investigated. Four years of mass trapping produced a 97% reduction in P. japonica numbers. Although this study lacked strict statistical controls, we feel it shows mass trapping for isolated Japanese beetle populations has merit. Therefore, under certain conditions mass trapping, as part of an integrated pest management program, may be useful for reducing P. japonica populations.

Biology and management of the Japanese beetle.

Advances in understanding host plant resistance, entomopathogens, and other biorational approaches may provide more options for integrated management of the Japanese beetle.

The sugar-beet weevil (Bothynoderes punctiventris Germar 1824., Col.: Curculionidae) : life cycle, ecology and area wide control by mass trapping

The sugar beet weevil (SBW) (Bothynoderes punctiventris, Germar 1824, Coleoptera: Curculionidae) is a very important pest of sugar beet. The life cyc


This review emphasizes recent research on the Japanese beetle’s biology and management and addresses abiotic and biotic factors affecting population dynamics of the root-feeding larvae.

Area-wide mass trapping by pheromone-based attractants for the control of sugar beet weevil (Bothynoderes punctiventris Germar, Coleoptera: Curculionidae).

It may not be possible to state that trapping alone can reduce the SBW population below the economic threshold level, but the data suggest that trapping can play an important role in the reduction of insecticide applications and in creating an integrated pest management plan for dealing with SBW under similar circumstances.

A degree-day model for forecasting adult phenology of Popillia japonica (Coleoptera: Scarabaeidae) in a temperate climate

Japanese beetle, Popillia japonica (Newman), was first detected in the United States in New Jersey in 1916. The beetle gradually spread to the Midwest U.S. region, and was first confirmed in

Aggregation and Male Attraction to Feeding Virgin Females in Macrodactylus subspinosus (F.) (Coleoptera: Scarabaeidae: Melolonthinae)

It is concluded that the act of feeding causes the immediate release of plant volatiles that act with normal levels of plant volatile release to increase adult attraction and virgin females enhance male attraction over mated females by causing the release of either female-based or plant-based volatile.

Pest categorisation of Popillia japonica

Popillia japonica does not satisfy all criteria necessary for it to be regarded as a Union regulated non‐quarantine pest (RNQP) and is likely to development over two years is likely across parts of northern Europe.

Entwicklung eines Konzeptes zur biologischen Bekämpfung des invasiven Japankäfers, Popillia japonica

A two-step biotest was developed and tested for the measurement of the mortality of the collected nematodes against P. japonica larvae under quarantine conditions with some improvements, such as increasing the number of repetitions for statistical purposes.

Maximizing information yield from pheromone-baited monitoring traps: Estimating plume reach, trapping radius, and absolute density of randomly moving insects

Fundamental knowledge of how to space traps and interpret catch numbers will enable pest mangers to make considerably more precise projections of damage and therefore more precise and reliable decisions on whether insecticide applications are justified and thereby set a new standard for IPM decisions based on trapping.

Efficacy of Entomopathogenic Nematodes and Entomopathogenic Fungi against Masked Chafer White Grubs, Cyclocephala spp. (Coleoptera: Scarabaeidae)

Nematodes alone or in combination with fungi were comparable to the insecticide Merit 75 WP against 3 rd instar Cyclocephala spp in the greenhouse, and showed better potential than insecticides for providing extended control of white grubs in the subsequent generation.

Traps Reduce an Isolated Infestation of Japanese Beetle

Populations of adult Popillia japonica Newman were reduced at least 50% at Nantucket, Massachusetts, by 3 years of mass trapping. Twenty-eight species of Scarabaeidae other than Japanese beetles were

Mass Trapping for Suppression of Japanese Beetles

In the United States the beetle found large areas of turf essential to development during its immature stages, a favorable climate with sufficient rainfall to prevent soil-inhabitants from desiccating and at least 350 plant species to act as hosts for adult beetles.

Efficiency of Japanese beetle (Coleoptera: Scarabaeidae) traps in reducing defoliation of plants in the urban landscape and effect on larval density in turf.

In experiments on a golf course and in home landscapes, single traps positioned at 3.1 or 9.3 m upwind or downwind from test plants failed to reduce defoliation compared with that which occurred on plants without traps, and defoliated was nearly always greater with a trap present.

Japanese Beetle (Coleoptera: Scarabaeidae) Traps: Evaluation of Single and Multiple Arrangements for Reducing Defoliation in Urban Landscape

Use of single Japanese beetle traps or small scale multiple trap arrangements will not prevent or reduce defoliation of nearby plantings and will probably increase the damage inflicted upon both highly preferred and relatively less attractive hosts.

Traps and Insecticide-Treated Foliage for Use Against the Japanese Beetle (Coleoptera: Scarabaeidae)

Several insecticides were applied to soybean foliage surrounding traps for Popillia japonica Newman baited with phenethyl propionate + eugenol + geraniol + Japonilure, and applications of bendiocarb to traps significantly decreased captures, an indication that this compound is repellent to the insect.
