A recent identification of the two-component aggregation pheromone invasive stink bug species, Halyomorpha halys (Stål), in association with a synergist, has greatly improved ability to accurately monitor seasonal abundance and distribution this destructive pest. We evaluated attraction H. black pyramid traps baited lures containing alone, synergist methyl (2 E ,4 ,6 Z )-decatrienoate (MDT) two combination. Traps were deployed around areas agricultural production including fruit orchards,...

Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is a highly polyphagous invasive species and an important pest of orchard crops in the United States. In Mid-Atlantic region, wild hosts H. are common woodlands that often border orchards, movement from them into orchards poses ongoing management issues. To improve our understanding host plant effects on populations at orchard-woodland interface, nymphal survivorship, developmental duration, adult fitness (size fresh weight) apple (Malus...

Reliable monitoring of the invasive Halyomorpha halys abundance, phenology and geographic distribution is critical for its management. adult nymphal captures on clear sticky traps in black pyramid were compared 18 states across Great Lakes, Mid-Atlantic, Southeast, Pacific Northwest Western regions United States. Traps baited with commercial lures containing H. pheromone synergist, deployed at field sites bordering agricultural or urban locations host plants. Nymphal greater than those...

Abstract BACKGROUND Introduction of Halyomorpha halys (Stål) in the USA has disrupted many established integrated pest management programs for specialty crops, especially apple. While current heavily relies on insecticides, one potential alternative tactic is attract‐and‐kill (AK), whereby large numbers H. are attracted to and retained a circumscribed area using attractive semiochemicals removed from foraging population with an insecticide. The goal this study was evaluate if AK...

Abstract We assessed the brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), seasonal patterns of host use and/or preference using three diverse approaches. compared H. captures in small pyramid traps baited with aggregation pheromone and deployed them mid‐canopy individual trees during discrete intervals over two seasons. Whereas were greatest late season, there was no significant effect tree species on captures, presence lures likely confounding results....

The invasive Halyomorpha halys invades crop fields from various bordering habitats, and its feeding on crops has caused significant economic losses. Thus, H. is considered a perimeter-driven threat, research alternative management tactics against it focused intervention at edges. Woodlands adjacent to contain many hosts of are therefore “riskiest” in terms pest pressure injury. However, tree fruit orchards the Mid-Atlantic, USA, often bordered one or more sides by woodlands other including...

Since the initial detection of invasive Halyomorpha halys (Stål) in United States late 1990s, this insect has emerged as a severe agricultural and nuisance pest. Nuisance problems are due to adult dispersal overwintering sites fall at which time they alight onto eventually settle within human-made structures addition natural harborage. This study examined how three factors, elevation, light, moisture affected site selection by H. mid-Atlantic. Observational counts performed along elevational...

The brown marmorated stink bug, Halyomorpha halys (Stål), is an invasive species from Asia capable of causing severe agricultural damage. It can also be a nuisance pest when it enters and exits anthropogenic overwintering sites. In recent years, pheromone lures traps for H. have been developed used to monitor populations in field studies. To date, no study has investigated the applicability these monitoring tools use indoors by building residents during period. Herein, we 1) assessed late...
