Monitoring and Biosurveillance Tools for the Brown Marmorated Stink Bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae)

Abstract

Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is an invasive pest of numerous agricultural crops with an increasing global distribution. Finding simple and reliable monitoring tools for H. halys agricultural and surveillance programs is imperative. In 2016, we compared standard pyramid traps to clear sticky cards attached atop wooden stakes and evaluated two commercially formulated lures (Trécé and AgBio) with low and high rates of the H. halys aggregation pheromone (PHER) and pheromone synergist (MDT) at 12 sites (low: 5 mg PHER + 50 mg MDT; high: 20 mg PHER + 200 mg MDT). In 2017, we reevaluated lure efficacy using only the clear sticky traps at six locations. Sites were classified as having low, moderate, or high relative population densities of H. halys in 2016, and as very low or low densities of H. halys in 2017. Although clear sticky traps captured fewer adults and nymphs than pyramid traps, their captures were generally correlated at all population levels indicating that clear sticky traps can reliably monitor H. halys presence and relative abundance regardless of relative population density. During both years, adult and nymphal captures were significantly greater in traps baited with Trécé lures than with AgBio lures. Captures were greater in traps baited with high loading rate lures for each lure type, and with the exception of traps baited with AgBio lures at high relative density sites in 2016, H. halys captures in traps with low and high loading rates of each lure type were correlated for both years. Comparison of yellow and clear sticky cards indicated they performed equally, but yellow cards captured more nontargets. In summary, clear sticky traps attached atop wooden posts and baited with H. halys pheromone and pheromone synergist lures are an effective option for this pest monitoring and detection.

Identification of Candidate Olfactory Genes in the Antennal Transcriptome of the Stink Bug Halyomorpha halys

“…The brown marmorated stink bug Halyomorpha halys (Hemiptera: Pentatomidae) is a major agricultural pest that is native to much of Asia. In the past 20 years, this pest has invaded parts of North America, South America, and Europe, causing great economic losses and degrading the ecosystem dynamics ( Acebes-Doria et al, 2018 ). H. halys is a polyphagous pest that can feed on at least 88 host plants including fruits, vegetables, crops, nuts, weeds, and wild plants ( Bergmann et al, 2016 ; Botch and Delfosse, 2018 ).…”

Nutrient Content of Brown Marmorated Stink Bug Eggs and Comparisons Between Experimental Uses

“…Wild adults have lower body mass ( Funayama 2012 ), and glycogen and sugar stores following diapause ( Skillman 2017 ). BMSB nymphs that feed on mixed diets develop quickly into adults that have higher nutrient stores than nymphs fed single or suboptimal diets ( Acebes-Doria et al 2016 , Acebes-Doria 2016 ). Clearly seasonality and diet affect nutrient stores in adults, but additional factors likely affect maternal provisioning as well.…”

Trapping Brown Marmorated Stink Bugs: “The Nazgȗl” Lure and Kill Nets

“…This experiment aimed to estimate the catch efficiency of BMSB adults and nymphs from the two trapping devices most frequently used commercially. Trapping was conducted in August and September 2018 at Fondazione Edmund Mach (46 • (1) (3S,6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol and (3R,6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol [22] plus (2) methyl (E,E,Z)-2,4,6-decatrienoate that works synergistically with the bisabolenes to attract BMSB to traps [23,27].…”

“…Tree-level attract and kill has the potential to reduce damage in orchards, but so far it is very expensive [26]. We chose to use sticky panels as a reference system due to extensive previous testing [27], for comparison with alternative traps under an expanding BMSB population in the north of Italy. While there is no proposal to use sticky traps as a control tool using mass trapping, our goal was to determine what improvements could be made to support an incursion response.…”
