Stink bugs are major pests in diverse crops around the world. Pest management strategies based on insect behavioral manipulation could help to develop biorational management strategies of stink bugs. Insect mating disruption using vibratory signals is an approach with high potential for pest management. The objective of this work was to investigate the effect of conspecific female rival signals on the mating behavior and copulation of three stink bug species to establish their potential for mating disruption. Previously recorded female rival signals were played back to bean plants where pairs of the Neotropical brown stink bug, Euschistus heros, and two green stink bugs, Chinavia ubica and Chinavia impicticornis were placed. Vibratory communication and mating behavior were recorded for each pair throughout the experimental time (20 min). Female rival signals show a disrupting effect on the reproductive behavior of three conspecific investigated stink bug species. This effect was more clearly expressed in E. heros and C. ubica than in C. impicticornis. The likelihood of copulating in pairs placed on control plants, without rival signals, increased 29.41 times in E. heros, 4.6 times in C. ubica and 1.71 times in C. impicticornis. However, in the last case, the effect of female rivalry signals in copulation was not significant. The effect of mating disruption of female rival signals of the three stink bug species may originate from the observed reduction in specific vibratory communication signals emitted, which influences the duet formation and further development of different phases of mating behavior. Our results suggest that female rival signals have potential for application in manipulation and disruption of mating behavior of stink bugs. Further work needs to focus on the effects of female rival signals used in long duration experiments and also their interactions with chemical communication of stink bugs.

Vibratory Signals

We describe different aspects of the reproductive biology, mating behavior, and vibratory communication of the pentatomidEdessa meditabunda(Fabr.). This species shows lower copulation frequency and reproductive potential with longer sexual maturation period compared to other species of pentatomids. Females with multiple mating show increased fecundity when compared with single-mated females and both increased fecundity and reduced longevity when compared with virgin females. Courtship and mating behavior and vibratory signals are typical and similar to what was observed in other species of pentatomids, except that males started the courtship. These results constitute the first paper on biology, behavior, and vibratory communication among species of the subfamily Edessinae.

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.

Laboratory Bioassays

Laboratory bioassays and field trials were conducted to evaluate the efficacy of selected organophosphate, pyrethroid, and neonicotinoid insecticides, as well as a chitin inhibitor, novaluron, against 2 common stink bug pests in Virginia, the green stink bug, Acrosternum hilare (Say), and the brown stink bug, Euschistus servus (Say). Green bean dip bioassays revealed differences in insecticide susceptibility between the 2 species. Acrosternum hilare adults were highly susceptible to all pyrethroids tested, the organophosphates except acephate, and the neonicotinoids except acetamiprid. Acrosternum hilare nymphs were also susceptible to all pyrethroids tested. In general, the neonicotinoids, dinotefuran and clothianidin, were toxic to A. hilare, whereas thiamethoxam and acetamiprid were toxic to E. servus. In field trials in soybean, the neonicotinoids, dinotefuran, imidacloprid, and thiamethoxam were efficacious at controlling stink bugs and, in general, performed comparably to the organophosphates and pyrethroids. These results indicate that neonicotinoid insecticides offer an alternative to growers for managing stink bugs that may fit with integrated pest management programs where conservation of natural enemies is a consideration.

ABSTRACT This study evaluates the effects of combinations of pyrethroids and neonicotinoids on the control of stink bugs at different stages of soybean crop development. The experiment was set up in a factorial randomized block design (4×6: 4 treatments and 6 stages) with 4 repetitions. The following treatments were tested during the V6/V7, R2, R4, R5.1, R5.5 and R 6 phenological stages: 1 – control (no application), 2 – thiamethoxam + λ-cyhalothrin, 3 – acetamiprid + α-cypermethrin, and 4 – dinotefuran + α-cypermethrin. Infestation, number of damaged seeds, number of pods, number of pods per plant, and yield (kg/ha) were evaluated. Stink bug infestations were smaller when applications commenced during the vegetative stages (V6-V8). Pod numbers and yields were highest in the dinotefuran + α-cypermethrin treatment with applications from V6/V8 to R4. The active ingredients dinotefuran + α-cypermethrin reduced stink bug populations and increased yields and could therefore be considered in integrated pest management (IPM) programs for soybean crops.

Vibratory Signals

This review represents complex mechanisms and processes of multimodal communication in stink bugs. During reproductive behavior the airborne and substrate-borne signals enable mate recognition, mediate directionality of movement, eliminate rivals and motivate partners for copulation. Species specific characteristics prevent hybridization at various levels of mating behavior. Male sex and/or aggregation pheromones as uni- or multicomponent signals attract mates to land on the same plant and there, trigger females to call males by vibratory signals, transmitted through the plant. Communication during courtship runs at short distance with visual, airborne, substrate-borne and contact chemical and mechanical signals. Abdomen vibrations produce the main repertoire of female and male calling, courtship and rival vibratory signals. To increase their informational value, stink bugs tune signal frequency, amplitude and temporal characteristics with mechanical properties of plants. The airborne component of species non-specific and high amplitude signals, produced by body tremulation and wing buzzing enables communication contact between mates standing on mechanically isolated plants. Female vibratory signals increase the amount of male emitted pheromone and the latter keeps female calling. Interaction, synergy and characteristics of visual, contact chemical and vibratory signals, exchanged during courtship remain under-investigated. Female and male competition for access to copulation in imbalanced sex conditions is characterized by duetting with rival song vibratory signals. Different receptors in and on different parts of the body are able to detect with high sensitivity multimodal airborne and substrate-borne communication signals. The relevance of the multimodal communication for the reproductive success of stink bugs is discussed.

The response of epiphytic populations of Pseudomonas syringae and other bacteria on dry bean plants to four copper-based bactericides was evaluated. The bactericides showed little difference in efficacy, but epiphytic populations on pinto bean leaflets, flowers, and pods were occasionally reduced when compared to populations on non-treated control plants, especially after repeated bactericide applications. Although there was a trend toward a relationship between epiphytic leaflet and flower populations, there were cases where P. syringae was undetected on one organ but abundant in samples from the other organ. P. syringae pv. syringae strains recovered from epiphytic populations demonstrated much greater copper resistance than did strains of P. syringae pv. phaseolicola, as measured by growth on media amended with cupric hydroxide. This difference between the pathovars may have implications for integrated pest management strategies.

AbstractHalyomorpha halys Stål (Hemiptera: Pentatomidae), the brown marmorated stink bug (BMSB), has been intercepted numerous times in Canada, and overwintering BMSB adults have been reported by homeowners. However, established breeding populations were not detected before 2012. Here we report the occurrence of established populations of BMSB in southern Ontario, Canada and describe habitats, host plants, and collection efforts from 2012 to 2013. Tracking the phenology and spread of this pest in Ontario is critical for the development of integrated pest management strategies to prevent severe economic damage due to this pest.

An experiment was established to determine the effect of different tillage practices, vegetable crop rotations, and pest management strategies on crop yield, plant diseases, pest and beneficial arthropods, weed species changes over time, and soil environmental consequences. This poster describes nitrogen movement from the various treatments over a 3-year rotation. The treatments are: 1) conventional tillage with chemically based IPM; 2) conventional tillage with biologically based IPM; 3) conservation tillage with chemically based IPM; 4) conservation tillage with biologically based IPM; and 5) conventional tillage with no fertilizer or pest management. Mid-season soil analyses with depth showed chemical-fertilized plowed and conservation-tilled treatments with more soil available nitrogen at most depths compared to the biological-based IPM systems (soybean meal was used as a nitrogen source). However, the biological-based systems did supply enough soil nitrogen to produce similar yield results as the chemical-based systems. Less soil nitrate was measured in the 30- to 90-cm depths at harvest from the biological-based systems than chemical-based systems. Conservation-tilled systems had greater nitrate with depth compared to conventional-tilled systems.
