Information concerning the presence of stink bugs in blackberry (Rubus spp.) in Brazil is sparse. This study aimed to identify the stink bug species associated with blackberry, to establish the daily dynamics and evaluate the fruits damage. The experiment was conducted in Santa Maria, Rio Grande do Sul State, Brazil, in blackberry orchard. Presence and evaluations of stink bugs were done weekly through visual and sweeping samplings at different day times. Five species of pentatomids were identified: Piezodorus guildinii, Nezara viridula, Euschistus heros, Dichelops furcatus and Edessa meditabunda. The bugs attack the drupelets producing a dark brown spot and wrinkled berries.

Decision Making Tool

Capture of stink bugs (Heteroptera: Pentatomidae) in apple orchards with yellow pyramid traps baited with Euschistus spp. (Heteroptera: Pentatomidae) aggregation pheromone, methyl (2E,4Z)-decadienoate, was 4 fold greater when traps were topped with a 3.8-L jar with a 1.6 cm diameter opening and trimmed wire edging than with a 1.9-L jar with a 5 cm diameter opening with no wire edging. Stink bug capture in the 3.8-L jar top was unaffected by the presence or size of an insecticide ear tag, indicating that this improved design led to increased captures by reducing escape. Sixty-four percent fewer stink bugs escaped from 3.8-L jar tops with the improved capture mechanism than from the 1.9-L jar tops. Green stink bug, Acrosternum hilare (Say), was more susceptible to the presence of the insecticide ear tag than the brown stink bug, Euschistus servus (Say), with dusky stink bug, E. tristigmus (Say), exhibiting high mortality in traps with and without ear tags. Among baited and unbaited pyramid traps with different visual stimuli, fewer captures were recorded in black pyramid traps than in clear, yellow, green or white pyramid traps. Similar numbers of brown stink bugs were captured in yellow pyramid traps deployed on the ground between trees or on horizontal branches within trees in the orchard border row. Captures of dusky and green stink bugs were greater in the tree pyramid, especially from August to mid-October. Relationships between stink bug capture and injury will need to be determined before this trap can be incorporated as a decision-making tool in pest management programs.

Background: Herbivorous insects are one of the main biological threats to crops. One such group of insects, stink bugs, do not eat large amounts of tissue when feeding on soybean, but are damaging to the quality of the seed yield as they feed on green developing seeds leading to poorly marketable harvests. In addition to causing physical damage during sucking-feeding activities, the insects can also transmit microbial pathogens, leading to even greater yield loss. Conducting surveys of the insect intestinal microbiome can help identify possible pathogens, as well as detail what healthy stink bug digestive systems have in common.Methods: We used the conserved V4 region of the 16S rRNA gene to characterize the bacterial microbiome of the red-banded stink bug Piezodorus guildinii collected in Brazil and the United States, as well as the neotropical brown stink bug Euschistus heros collected in Brazil.Results: After quality filtering of the data, 192 samples were kept for analyses: 117 samples from P. guildinii covering three sites in Brazil and four sites in the United States, and 75 samples for E. heros covering 10 sites in Brazil. The most interesting observations were that the diversity and abundance of some bacterial families were different in the different ecoregions of Brazil and the United States.Conclusion: Some families, such as Acetobacteraceae, Bacillaceae, Moraxellaceae, Enterobacteriaceae, and Rhodocyclaceae, may be related to the better adaptation in some localities in providing nutrients, break down cellulose, detoxify phytochemicals, and degrade organic compounds, which makes it difficult to control these species.

AbstractThe objective of this study was to evaluate the composition and abundance of dormant bedbugs in Chloris distichophylla Lag (Poales: Poaceae) over the soybean and corn off-season. The work was carried out in the municipality of Cruz Alta, over the soybean and corn off-season between 2014 and 2018. Plants of C. distichophylla with different clump diameter were sampled, and the bugs contained in them were counted and submitted to data analysis for the evaluation of the composition, structure, and diversity of occurring species. At the end of the experiment, 3543 hibernating adults were counted and divided into six species: Euschistus heros (F.), Dichelops furcatus (F.), Dichelops melacanthus Dallas, Edessa meditabunda (F.), Edessa ruformaginata (De Geer) (Hemiptera: Pentatomidae). The species E. heros was the most abundant, followed by D. furcatus. The diameter of the clumps directly affects the population density of the stink bugs. Finally, C. distichophylla is shown as a hibernate favorable to the maintenance of the stink bug populations over the soybean and corn off-season.

Studies were conducted in the laboratory and in growth chambers to determine if the location of particular seeds within soybean pods were preferred by adult Nezara viridula (L.), Euschistus heros (F.), and Piezodorus guildinii (Westwood) (Heteroptera: Pentatomidae). Results demonstrated that feeding frequency, as indicated by the number of punctures (i.e., stylet sheaths), was significantly greater (P < 0.05) on the proximal seed, than on other seeds, both for detached pods and pods on plants. In general, the number of punctures on the proximal seed was 2–3X greater than punctures observed in the medial or distal region. Of the three species studied, N. viridula showed the greatest feeding activity and P. guildinii the least. No significant differences in feeding activity between sexes were observed. N. viridula fed more frequently at 22 than at 29°C, while no significant temperature effect was observed for E. heros.

On Farm

The objective of this on-farm study was to determine if peanuts harbor populations of stink bugs (Heteroptera: Pentatomidae) and their natural enemies in Georgia. Eight species of phytophagous stink bugs were found in peanuts over the 5-yr study. The predominant stink bug species were Nezara viridula (L.), Euschistus servus (Say), Euschistus quadrator (Rolston), and Oebalus pugnax pugnax (F.). The remaining 4 species, Acrosternum hilare (Say), Euschistus tristigmus (Say), Euschistus ictericus (L.), and Thyanta custator accerra McAtee, were found in relatively low numbers. All developmental stages of N. viridula, E. servus, E. quadrator, A. hilare, and O. p. pugnax were collected at various times in the study indicating that these 5 species of stink bugs were developing on this crop. Seasonal abundance of N. viridula and E. servus nymphs and adults provided further support that these 2 species of stink bugs developed on peanuts. At least 1 generation of N. viridula and E. servus occurred in peanuts each year, and generally some of the adults that developed on peanuts oviposited on peanuts producing another generation of nymphs in this crop. Because only adults of T. c. accerra, E. tristigmus, and E. ictericus were found in peanuts, these 3 stink bug species probably were not developing on this crop. Adult stink bugs were parasitized by the tachinid parasitoids Trichopoda pennipes (F.) and Cylindromyia spp. Stink bug eggs were parasitized by the scelionids, Trissolcus basalis (Wollaston), Trissolcus thyantae Ashmead, Trissolcus brochymenae (Ashmead), Telenomus podisi Ashmead, and Gryon obesum Masner, and an unknown encyrtid species. Geocoris punctipes (Say), Geocoris uliginosus (Say), Orius insidiosus (Say), Podisus maculiventris (Say), and Oxyopes salticus Hentz preyed on stink bugs in peanuts. Peanuts harbor populations of stink bugs and their natural enemies, and thus the role peanuts play in landscape ecology of stink bugs needs to be ascertained to better understand how to manage stink bug populations in landscapes in which peanuts are associated with other crops.
