Abstract Determining the host range of an invasive insect in a new environment is a key step in the development of management strategies. As the brown marmorated stink bug, Halyomorpha halys Stål, expands into agricultural regions of North America, efforts to elucidate its dietary habits on a landscape scale rely on intensive sampling of potential host plants. Although this approach yields useful information, results can be biased toward common and easily sampled plant species; important hosts can be missed if sampling them is impractical or limited in scope. Here we lay the groundwork for the application of gut content analysis to the feeding ecology of H. halys by investigating the persistence of host plant DNA in the digestive tracts of insects with known feeding histories. Adult H. halys were fed bean seedlings (Phaseolus lunatus L.) for 7 d, followed by a forced host switch to carrot (Daucus carota L.). Insect guts were dissected out at 0, 1, 3, 7, and 14 d following the switch, and host plant chloroplast genes (trnF and trnL) were amplified via polymerase chain reaction. Amplicons were identified using high-throughput sequencing and analyzed for Phaseolus DNA. The original host remained detectable at 3 d (trnF) and 14 d (trnL) in substantial quantities. The proportion of total reads identified as Phaseolus rapidly decreased with time; a concomitant increase in Daucus reads was observed. Our results indicate that high-throughput sequencing of gut contents has great potential for exploring the dietary histories of field-caught H. halys and other phytophagous insects.

Brown marmorated stink bug (Halyomorpha halys Stål) is an invasive agricultural pest that causes severe damage to many crops. To determine potential associations between H. halys feeding damage, Fusarium infection, and mycotoxin contamination in field corn, a field survey was conducted in eight counties in Virginia. Results indicated an association between H. halys feeding damage and fumonisin contamination. Subsequent field experiments in Delaware, Maryland, and Virginia examined the ability of H. halys to increase Fusarium verticillioides (Sacc.) Nirenberg infection and fumonisin concentrations in corn. At the milk stage, H. halys (0 or 4 adults) and Fusarium (with or without F. verticillioides inoculum) treatments were applied to bagged ears in a two by two factorial randomized complete block design with 12 replicates. H. halys treatments increased levels of feeding damage (P < 0.0001) and Fusarium infection (P = 0.0380). Interaction between H. halys and Fusarium treatments influenced severity of infection (P = 0.0018) and fumonisin concentrations (P = 0.0360). Results suggest H. halys has the ability to increase both Fusarium infection and fumonisin concentrations in field corn. Further studies are needed to understand mechanisms by which H. halys increases fumonisin and to develop management strategies to mitigate impacts of H. halys on field corn in the region.

Fruit Damage

The brown marmorated stink bug (BMSB) would have wide-ranging and likely devastating effects on New Zealand’s horticultural industries if it were to establish here. This insect has spread rapidly around the world, becoming pestiferous only a few years after detection; therefore, there will be limited time to develop management strategies to prevent damage if viable BMSB populations were to establish in New Zealand. Lures containing BMSB pheromone paired with 92 sticky panels were deployed near transitional facilities and other potentially high-risk entry points in the Auckland, Hawke’s Bay and Nelson regions. Traps were monitored fortnightly from November 2018 to April 2019 and all pentatomid species identified and enumerated. No BMSB were captured, but seven other pentatomid species were caught. Numbers and species varied among site, region and date. The phenology of the pentatomids captured supports reports of one to two generations occurring in pipfruitproduction regions depending on growing-degree days. The phenologies of the pentatomid species caught suggest that any control measures for prevention of fruit damage by BMSB would be limited to late summer. A number of recommendations for a BMSB monitoring programme are provided.

High-throughput sequencing analysis of gut contents was used to study the feeding habits of two filter-feeding fish, namely silver carp Hypophthalmichthys molitrix and bighead carp Hypophthalmichthys nobilis, in mesotrophic Lake Qiandao and eutrophic Lake Taihu. Silver carp feed primarily on phytoplankton, with a feeding preference for Chlorophyta, in Lake Qiandao and rely on phytoplankton in Lake Taihu. Bighead carp feed more on zooplankton in Lake Qiandao and on phytoplankton in Lake Taihu. With increasing levels of algae, bighead carp feed more on phytoplankton. The dietary shifts suggest that bighead carp would be useful in controlling nuisance algae in lakes.

Abstract Background: In the past decade, the brown marmorated stink bug (BMSB), Halyomorpha halys (Hemiptera: Pentatomidae) has caused extensive damage to global agriculture. As a high-risk pest for many countries, including New Zealand, it is important to explore its genetic diversity to enhance our knowledge on and devise management strategies for BMSB populations. In this study, two mitochondrial genes, Cytochrome c oxidase I (COI) and Cytochrome c oxidase II (COII) were used to explore the genetic diversity among 463 BMSB individuals collected from 12 countries. Result: In total, 51 COI and 29 COII haplotypes of BMSB were found, which formed 59 combined haplotypes (5 reported and 54 novel). Of these, H1h1 was the predominant haplotype. The haplotype diversity (Hd) and nucleotide diversity (π) were high while the neutrality (Fu's Fs) values were negative for the BMSB populations in the native countries, China, and Japan. For the BMSB populations from the invaded countries, the Fu's Fs values were negative for populations from Chile, Georgia, Hungary, Italy, Romania, Turkey, and USA, indicating that those populations are under demographic expansion. In comparison, the Fu's Fs values were positive for the populations from Austria, Serbia, and Slovenia, revealing a potential population bottleneck. Analysis of molecular variance (AMOVA) suggested that significant genetic difference exist between groups of populations: China, Japan, and the invasive populations. Conclusion: This study revealed that the haplotype diversity of the BMSB populations was high in those two studied countries where BMSB is native to (China and Japan) but low in those countries which have been invaded by the species. The analysis indicated that multiple invasions of BMSB occurred and a new stable genetic cluster has established in Europe and the USA. The study also revealed that three ancestral lines and most of the novel haplotypes were evolved from them. Moreover, we observed two genetic clusters in the invasive populations that are formed during different invasion events. Our study provided a comprehensive overview on the global haplotypes distribution thus expanding the existing knowledge on BMSB genetic diversity that potentially could play an important role in formulating feasible pest management strategies, especially biocontrol.

Pest Monitoring

Hazelnut crops are damaged by various types of polyphagous true bugs. The most commonly encountered species are representatives of the families Coreidae and Pentatomidae (Hemiptera: Heteroptera) Recent invasion of the exotic brown marmorated stink bug Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) represents a serious threat in many agroecosystems in Europe. Following its first detection, H. halys has become a key pest in many hazelnut crops in Europe, causing damage throughout the entire period of nut and kernel development. The pest causes damage in adults and larval stages by sucking sap from practically all parts of plants. This bug is characterized by a distinct polyphagous behavior, so to date, more than 300 plant species have been identified as food hosts. Halyomorpha halys was first registered in Serbia in October 2015 in the region of Vršac. Detection of brown marmorated bug in hazelnut crops in Serbia calls for caution and requires systematic monitoring of this pest in order to determine an adequate strategy for plant protection and accurate timing of its control. In hazelnut crops, this bug causes damage by sucking juices from the husk, shell and kernel of the fruit, which significantly reduces the quality and market value of the hazelnut fruit. Management of the brown marmorated stink bug in agricultural settings has primarily relied on the use of broad-spectrum of insecticides. In the system of Integrated Pest Management, the control of H. halys is based on a strategy that implies a reduced and effective use of insecticides and a distinct knowledge of the biology and behavior of the pest. Monitoring insect populations is a fundamental component of Integrated Pest Management programs. In a perspective of reduction or avoidance of chemical treatments and preservation of a healthy agroecosystems, such as the, alternative pest management strategies in hazelnut orchards should be further developed. Moreover, as a long-term solution, biological control of H. halys with the natural enemy species, native or introduced, could play a major role in managing this pest, especially in organic farming systems.
