    Bean leaf beetle (Coleoptera: Chrysomelidae) preference for two Phaseolus beans over soybean
    Shrader, Meredith Edana; Kuhar, Thomas P.; Schultz, Peter B.; Pfeiffer, Douglas G.; Kamminga, Katherine (2014)
    In the eastern and central U.S., bean leaf beetle, Cerotoma trifurcata (Förster) (Coleoptera: Chrysomelidae), is a pest of legume crops, on which adults chew holes in leaves, can destroy seedlings, and can injure pods (Smelser and Pedigo 1992a, J. Econ. Entomol. 85: 2408 - 2412; Smelser and Pedigo 1992b, J. Econ. Entomol. 85: 2399 - 2403; Koch et al. 2005, Crop Prot. 24: 734 - 742). The beetle is also a primary vector of bean pod mottle virus, which can further reduce yield and seed quality in soybeans (Giesler et al. 2002, Plant Dis. 86: 1280 - 1289). On the Delmarva Peninsula, snap beans (Phaseolus vulgaris L.), lima beans (Phaseolus lunatus L.), and soybeans (Glycine max (L.) Merr.), are each important crops, and relatively high populations of C. trifurcata occur. To better understand the potential intercrop movement of the beetle and its implications for pest management, we conducted beetle host plant preference experiments...

    Biology and Management of the Green Stink Bug
    Kamminga, Katherine; Koppel, Amanda Leigh; Herbert, D. Ames Jr.; Kuhar, Thomas P. (Entomological Society of America, 2012-12-01)
    The green stink bug, Acrosternum hilare (Say) [Chinavia hilaris (Say)] (Hemiptera: Pentatomidae) is one of the most damaging native stink bug species in the United States. It is a pest of economic importance in a variety of commodities, including cotton (Gossypium hirsutum L.), soybeans [Glycine max (L.) Merr.], tomatoes (Solanum lycopersicum L.), and peaches [Prunus persica (L.) Batsch]. Stink bug feeding can result in cosmetic damage as well as reduced quality and yield. Acrosternum hilare and other stink bugs have become a major challenge to integrated pest management systems because control options are basically limited to the application of broad-spectrum insecticides such as organophosphates, carbamates, and pyrethroids. However, neonicotinoids are generally effective for control of this stink bug and may be less disruptive to natural enemies. Further options for stink bug management that are being explored include the use of trap crops and enhancing beneficial parasitoid populations. The green stink bug is native and found throughout the United States. It has a wide host range, and is a pest of many agricultural commodities. The green stink bug can cause feeding injury to fruit, vegetable, and field crops that may require preventative management. Many strategies are available for its control, which include multiple chemical, cultural, and biological options. Broad-spectrum insecticides such as pyrethroids and organophosphates, as well as the less toxic neonicotinoids, are efficacious against the green stink bug. Cultural options, including trap cropping and the planting of resistant varieties, have been documented as decreasing crop injury by stink bugs. In addition, there are multiple natural enemies that reduce population numbers.

    First report of a mermithid nematode infecting Piezodorus guildinii and Acrosternum hilare (Hemiptera: Pentatomidae) in the United States
    Kamminga, Katherine; Davis, Jeffrey A.; Stock, S. Patricia; Richter, Arthur R. (Florida Entomological Society, 2012-03)
    Stink bugs (Hemiptera: Pentatomidae) are important economic pests of many agricultural crops, and have become one of the most difficult pest complexes to control in field crops, vegetables and fruit trees (McPherson & McPherson 2000). Stink bugs usually attack developing fruiting structures, and direct damage to the fruit is caused by insertion of their stylets to feed on plant fluids. In soybeans (Glycine max (L.) Merr.), stink bug feeding can cause delayed maturity and reduce seed quality, yield and germination (Underhill 1934; Chyen et al. 1992).

    Species survey, monitoring and management of economically important stink bug species in eastern Virginia
    Kamminga, Katherine (Virginia Tech, 2008-10-23)
    Stink bugs are major pests of agricultural crops throughout Virginia and much of the United States. Knowledge of the biology, the species complex, and insecticide susceptibility can improve management. A survey was conducted in Virginia to determine the species complex in soybean and cotton and to monitor for nonnative species. Seven stink bug species were identified. Acrosternum hilare (Say) and Euschistus servus (Say) were the most common. Two sampling methods, the sweep net and the beat sheet, were assessed in soybean and cotton. There was less variability with the sweep net method compared to the beat sheet method. Laboratory bioassays and field trials were conducted to evaluate the toxicity and efficacy of selected conventional and organic insecticides against A. hilare and E. servus. In bioassays with conventional insecticides, A. hilare adults and nymphs were susceptible to all pyrethroids tested. Generally, the neonicotinoids, dinotefuran and clothianidin, were more toxic to A. hilare, while thiamethoxam and acetamiprid were more toxic to E. servus. In soybean field efficacy trials, dinotefuran performed comparably to the organophosphates and pyrethroids. Laboratory bioassays with organic insecticides resulted in moderate to high levels of mortality, and in antifeedant and repellency responses. Likewise, soybean field trials indicated that a single application can reduce stink bug numbers for up to two days after treatment; however in tomato field trials multiple weekly applications did not result in significant reductions in stink bug damage. A weather model to predict abundance of A. hilare adults was developed using weekly black light trap catch data collected from 1990 to 2007 at a single location. The two weather variables that resulted in a significant model were days below freezing and mean monthly precipitation from January to April. The model was validated by correlating five independent data sets to predicted weekly trap catch. Mean trap catch plotted over time showed three peaks. In accordance with A. hilare developmental rates, the peaks indicated that two generations and a partial third occur in Virginia. Cumulative trap catch estimated from the 18-yr trap catch mean showed that 10, 50, and 90% of the total seasonal catch should occur by 153, 501, and 1066 degree days, respectively.
