ABSTRACT Traps containing a combination floral and synthetic pheromone lure are used to monitor and manage Japanese beetles, Popillia japonica Newman (Coleoptera: Scarabaeidae). One key factor limiting trap effectiveness for beetle control is the “trap spillover” phenomenon, in which the trap attracts beetles without capturing them, resulting in increased damage to surrounding host plants. We investigated the mechanisms underlying trap spillover by conducting two studies in a soybean field in… 
Use of aggregation pheromone traps increases infestation of adult Riptortus pedestris (Hemiptera: Alydidae) in soybean fields.
TLDR
Aggregation pheromone traps did not reduce R. pedestris populations in the field or soybean damage, and even led to an increase in the bug population during autumn, therefore, traps should not be used as a control measure.
Traps and Trap Placement May Affect Location of Brown Marmorated Stink Bug (Hemiptera: Pentatomidae) and Increase Injury to Tomato Fruits in Home Gardens
TLDR
No evidence that stink bug traps protected tomatoes from H. halys is found, and it appears that the addition of traps to gardens may increase injury to tomato fruits.
Mass Trapping Drosophila suzukii, What Would It Take? A Two-Year Field Study on Trap Interference
TLDR
It was found in this two-year field study that workable trap densities can be expected to control D. suzukii control and how far traps should be maximally spaced in a grid was found.
Evaluation of aggregation and alarm pheromones of Riptortus pedestris (Hemiptera: Alydidae) as a push–pull strategy in soybean fields
TLDR
Traps used both with and without alarm pheromone failed to reduce the bug population to the level found when traps were not used, despite some positive effect of installation distance.
Avoiding Unwanted Vicinity Effects with Attract-and-Kill Tactics for Harlequin Bug, Murgantia histrionica (Hahn) (Hemiptera: Pentatomidae).
TLDR
More HB adults and more HB-feeding injury were observed on collard plants in the vicinity of lures compared with those neighboring lures in combination with a systemic toxicant, indicating that improvements to trap retention acted to mitigate spillover effects, thereby avoiding unwanted vicinity effects.
Effectiveness of Hand Removal for Small-Scale Management of Japanese Beetles (Coleoptera: Scarabaeidae)
TLDR
It is found that hand removal significantly lowered the number of beetles on, and consequently the damage to, grape plants relative to nonremoval controls.
Optimizing the Use of Semiochemical-Based Traps for Efficient Monitoring of Popillia japonica (Coleoptera: Scarabaeidae): Validation of a Volumetric Approach
Abstract Japanese beetle, Popillia japonica Newman, is an invasive insect, native to Japan. The species was detected in the United States in New Jersey in 1916, and then first confirmed in Minnesota
Evaluating a push-pull strategy for management of Drosophila suzukii Matsumura in red raspberry.
TLDR
Two behavioral control approaches in combination as a push-pull strategy reduced oviposition by D. suzukii, and the combination of the two resulted in significantly greater reduction than either treatment alone.
Dynamics of Aggregation Formation in Japanese Beetles, Popillia japonica
TLDR
Overall, the results indicate that female Japanese beetles may be the initiators of aggregations (i.e. the pioneers) with males joining later in the process, and suggest that females with fewer eggs and males with larger body sizes are more likely to join aggregations.

Japanese Beetle (Coleoptera: Scarabaeidae) Traps: Evaluation of Single and Multiple Arrangements for Reducing Defoliation in Urban Landscape
TLDR
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.
Mutual Interference of Pheromone Traps Within Trap Lines on Captures of Boll Weevils (Coleoptera: Curculionidae)
TLDR
It was found that the trap furthest upwind in the line captured the most weevils, especially on days of moderate wind speeds, and until the minimum adequate spacing has been established, traps should be placed at least 30 m apart in experiments in which such biases can adversly affect interpretation of results.
Efficiency of Japanese beetle (Coleoptera: Scarabaeidae) traps in reducing defoliation of plants in the urban landscape and effect on larval density in turf.
TLDR
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.
Efficiency of Two Gypsy Moth (Lepidoptera: Lymantriidae) Pheromone-Baited Traps
pheromone-baited Pherocon IC sticky traps that were relatively free of captured moths caught about twice as many male gypsy moths as USDA milk carton traps during natural male flight and also in
Modified Trap Designs and Heights for Increased Capture of Japanese Beetle Adults (Coleoptera: Scarabaeidae)
TLDR
Several trap designs and trap heights were tested on a golf course for effectiveness of capture of Japanese beetle adults and significantly more beetles were captured by traps with trap collection funnel rims compared with rims at 90 cm above the ground.
Factors Affecting the Differential Capture of Male and Female Codling Moth (Lepidoptera: Tortricidae) in Traps Baited with Ethyl (E, Z)-2,4-Decadienoate
TLDR
Evaluating factors that differentially affect the catch of male and female codling moth in traps baited with ethyl (E, Z)-2,4-decadienoate (pear ester) found that lure and kill strategies should include factors that optimize the captures of female moths.
Factors influencing consistency of a carrot rust fly (Diptera: Psilidae) monitoring program in British Columbia.
TLDR
A modified monitoring program for P. rosae is described that would be as effective, but more economical to operate than the existing program in British Columbia.
Migration in spruce bark beetles (Ips typographis L.) and the efficiency of pheromone traps
TLDR
Electroantennograms recorded in the laboratory at different times after emergence indicate that the delayed response to aggregation pheromones in migrating bark beetles is not the result of a delayed maturation of the antennal receptor cells, but obviously governed by the central nervous system.
Pine Weevil (Coleoptera: Curculionidae) Population Monitoring in Christmas Trees Using Volatile Host Compounds
TLDR
Ethanol- and turpentine-baited pitfall traps and flight traps, and pit traps baited with fresh pine billets, were used to characterize weevil species composition in north-central Kentucky and assess seasonal activity by exploiting the weevils' attraction to host plant volatiles.
Japanese beetle (Coleoptera: Scarabaeidae) response to color traps baited with phenethyl propionate + eugenol + geraniol (3:7:3) and japonilure
TLDR
Color did not significantly affect captures of male beetles in traps baited only with Japonilure, and traps painted white were the most attractive; they captured about one-third more beetles than standard yellow traps.
