“…As a result, the area of arrestment is larger for H. halys responding to the aggregation pheromone than for many moth pests responding to sex pheromones. This type of response may be broadly expressed in stink bugs, as other studies have documented a similar behavior of congregating around an aggregation pheromone on a host plant but not contacting the point source, for example in the case of Euschistus conspersus Uhler with methyl decadienoate-baited tubes on Verbascum thapsus L. (Krupke et al 2001). We have circumvented the dilemma of having H. halys contact a small point source of insecticide within a tree canopy by spraying the entire tree with the killing agent.…”

Establishing the behavioral basis for an attract-and-kill strategy to manage the invasive Halyomorpha halys in apple orchards

Halyomorpha halys (Stål), the brown marmorated stink bug, is an invasive, polyphagous insect that causes serious economic injury in particular to specialty crops in the United States. Growers have been forced to respond by increasing the frequency of broad-spectrum insecticide (e.g., neonicotinoid, pyrethroid, and carbamate) applications. One strategy to reduce reliance on insecticides is known as ''attract-and-kill'' whereby the targeted insect is attracted to a spatially precise location to be eliminated by a killing agent such as an insecticide. This approach can substantially reduce the amount of insecticide used by sparing alternate row middle or whole block sprays. For apple orchards, we propose baiting select border row trees with the H. halys aggregation pheromone and synergist and subsequently treating these baited trees with effective insecticides to kill H. halys throughout the growing season. To evaluate the behavioral basis of this approach, we conducted orchard trials with black pyramid traps, harmonic radar, and trials using baited apple trees sprayed weekly to quantify H. halys arrestment area, retention time, adult and nymph annihilation, and fruit injury in and near these attract-and-kill sites. The arrestment area for H. halys was confined to a 2.5 m radius around the pheromone-and pheromone synergist-baited trap regardless of pheromone dose (84 or 840 mg), while the retention capacity of adults was significantly increased by pairing the aggregation pheromone and synergist with a fruiting host plant compared with non-host sites. Damage to fruit harvested from baited attract-and-kill trees was high, but minimal in surrounding unbaited neighboring apple trees. Our results suggest attract-and-kill may be an effective strategy for managing H. halys season-long.Keywords Integrated pest management Á Brown marmorated stink bug Á Behaviorally based management Á Harmonic radar Á Invasive species Á Pheromone Á Hemiptera Á Pentatomidae Key messages• Halyomorpha halys management relies on repeated insecticide applications to susceptible crops. • We evaluated the behavioral basis for a proposed attract-and-kill strategy in apple as a means to reduce insecticide inputs. • We found that attract-and-kill holds promise as H. halys activity was confined to a small arrestment area around a pheromone source, and the use of harmonic radar showed that retention time at these sites was greatest when a host plant (apple) was present. • High kill of H. halys was achieved in baited attract-andkill apple trees season-long with minimal damage on adjacent unbaited trees.

“…halys was the most abundant pentatomid species on all hosts sampled, although the ornamental host plants we selected for sampling may have biased the pentatomid species composition found. Native Euschistus spp., for example, are known to prefer mullein and uncultivated hosts plants to ornamental hosts and could account for the low population levels observed (Panizzi 1997, Krupke et al 2001. Euschistus spp.…”

Host plant use by nymphs and adults of the nonnative species Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) was investigated proximal to the location of its introduction, Allentown, PA. The seasonality of H. halys in the United States had not been thoroughly studied before this work. It is reported to have Ϸ300 host plants in its native range that could make control and identiÞcation of small populations difÞcult. Weekly beat samples were conducted beginning at petal fall (mid-April) in Pyrus spp. until the Þrst frost (mid-October) from 2005 to 2007 on a variety of ornamental trees, shrubs, and agricultural crops. Egg masses were Þrst observed on Paulownia tomentosa Thunb. the Þrst week of June. In 2006 and 2007, Fraxinus americana L. was an important mid-and late season host for adults. Nymphal abundance differed seasonally. P. tomentosa supported high densities during the early season, whereas Viburnum opulus variety americanum Aiton was the preferred mid-season host, and Viburnum prunifolium L. and Rosa rugosa Thunb. had the highest densities of nymphs during the late season. Abundance of nymphs was strongly associated with maturing fruit or pods. All plants surveyed supported populations of H. halys, suggesting a large host range. In late August, a large adult population peak was observed (850 Ð1,000 degree days [DD]), shortly after the DD accumulation for development to imaginal eclosion, supporting hypotheses that H. halys is likely univoltine in this region. Relative to native pentatomid species, H. halys was by far the predominant species collected in samples on ornamental and cultivated crops.

“…This extreme male bias in the capture data was a unique phenomenon; it has not been reported in other heteropterans for which an aggregation pheromone has been found, such as P. stali (0.26-0.44, Moriya and Shiga, 1984), Alydus eurinus (Say) (Heteroptera: Alydidae) (ca. 0.75, Aldrich et al, 2000), E. conspersus (0.49-0.55, Krupke et al, 2001;0.26-0.48, Cullen and Zalom, 2005), and R. pedestris (ϭR. clavatus) (0.54, Tabuchi et al, 2005).…”

To improve the procedures for estimating the abundance of the rice bug, Leptocorisa chinensis Dallas (Heteroptera: Alydidae), field monitoring using traps baited with synthetic attractant was conducted in Tsukuba, central Japan from 2002 to 2006. A mixture of (E)-2-octenyl acetate and 1-octanol, in a ratio of 5 : 1 and incorporated into a plastic pellet, was used as bait on sticky boards and placed at study sites from early June to the end of October. The attractantbaited traps were able to detect the starting of the migration period of the overwintered generation and the population increase of the first generation. The number of trapped insects decreased rapidly after early September, while the number of insects in second generation increased in the grassy weeds field. The decreased temperatures and shorter daylength of autumn (which will have induced reproductive diapause) may have affected the attractiveness of the baited traps. The ratio of males to all captured L. chinensis was 0.88-0.96. Most captured adults had no food in their stomachs, and most males were sexually mature. These results indicate that the males trapped had actively moved for two possible reasons: to search for food and/or to search for females. Based on comparisons between the results of baited trap monitoring and sweep-net surveys, it was considered that immigrant period and density of L. chinenis in the poaceous plants fields depend on the density of dispersal individuals and the heading period of the plants.
