On Farm

The brown stink bug,Euschistus servus(Say), can disperse from source habitats, including corn,Zea maysL., and peanut,Arachis hypogaeaL., into cotton,Gossypium hirsutumL. Therefore, a 2-year on-farm experiment was conducted to determine the effectiveness of a sorghum (Sorghum bicolor(L.) Moench spp.bicolor) trap crop, with or withoutEuschistusspp. pheromone traps, to suppress dispersal of this pest to cotton. In 2004, density ofE. servuswas lower in cotton fields with sorghum trap crops (with or without pheromone traps) compared to control cotton fields. Similarly, in 2006, density ofE. servuswas lower in cotton fields with sorghum trap crops and pheromone traps compared to control cotton fields. Thus, the combination of the sorghum trap crop and pheromone traps effectively suppressed dispersal ofE. servusinto cotton. Inclusion of pheromone traps with trap crops potentially offers additional benefits, including: (1) reducing the density ofE. servusadults in a trap crop, especially females, to possibly decrease the local population over time and reduce the overwintering population, (2) reducing dispersal ofE. servusadults from the trap crop into cotton, and (3) potentially attracting more dispersingE. servusadults into a trap crop during a period of time when preferred food is not prevalent in the landscape.

Abstract Populations of the brown stink bug, Euschistus servus (Say), in Florida peach orchards were monitored during the 2017 and 2018 growing seasons using yellow pheromone-baited pyramid traps. Peaches were evaluated at harvest for the presence of stink bug injury. A relationship between E. servus trap capture and fruit injury was used to estimate the economic injury level (EIL) for varying scenarios of crop price, per-hectare yield, and control costs. Economic thresholds were then set based on observed E. servus population trends and expected rates of increase. Thresholds were lowest in the period immediately following shuck split due to the rapid increase in E. servus populations during this period. Euschistus servus trap capture trended downward at the time of harvest. Therefore, increased E. servus management early in the Florida peach season provides the greatest overall benefit, whereas late season populations decline independent of management actions. The proposed EIL for Florida peaches determined by this study is 5.53 E. servus per trap over a 14-d trapping period, which was surpassed in only 16 of the 60 recorded trapping periods. This suggests that the current recommended spray frequency may not be economically justified.

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.

Abstract Stink bugs (Hemiptera: Pentatomidae) are commonly monitored using pyramid traps baited with a pheromone. Initially, the pyramid traps were painted yellow and predominantly used to monitor native stink bug species. However, research studies involving the exotic Halyomorpha halys Stål (Hemiptera: Pentatomidae) now use pyramid traps that are black, not yellow. As H. halys moves across the southeastern United States, the use of a single trap, yellow or black, for monitoring and conducting research studies would be beneficial. Our objective was to compare black and yellow pyramid traps baited with a lure to determine if one was superior for trapping herbivorous stink bugs. This study was conducted at four locations, three in Alabama and one in Georgia, over 2 yr. Additionally, residual efficacy of the lure was measured via trap capture over 1-mo intervals. Our results showed that only when native stink bug species were combined, and only in 1 yr, were captures significantly affected by trap color. Capture of the exotic H. halys and the most abundant native species, Euschistus servus (Say), was not significantly affected by trap color. Trap capture was significantly affected by how long a lure was in a trap. The data from this study suggests that when traps are used in conjunction with a pheromone to monitor multiple species of adult stink bugs, especially native species, the yellow pyramid trap is favored.

Adult brown stink bugs, Euschistus servus (Say), were caged individually on limbs with apple fruit of 6 cultivars in research orchards in West Virginia. Studies were performed to describe specific characteristics of damage that could be used for field and/or laboratory diagnosis of stink bug injury to apple fruit at harvest. These characteristics were separated into surface and subsurface features. On the apple surface, 3 prevailing types of stink bug injury were observed in the field: (1) a discolored dot, i.e., stink bug feeding puncture; (2) a discolored dot with a depression in the fruit; and (3) a discolored dot with a discolored depression in the fruit. Subsurface characters were related to the extent of damage observed on the fruit skin. Common subsurface damage ranged from a stylet sheath to corky tissue of variable color, shape, and size that sometimes was not contiguous with the skin. Laboratory evaluations under a dissecting microscope revealed that the size of the stink bug feeding puncture was ~0.17 mm diam. This character was the only consistent, definitive symptom of stink bug injury present among all observed damage. Due to variability in other surface and subsurface characters, and potential problems with visual apparency of injury in the field, evaluations of suspected stink bug damage should be performed with 40X magnification in the laboratory to confirm the presence of stink bug feeding punctures.

AbstractPrevious efficacy studies found that many insecticides used by growers could be having an adverse effect on egg parasitoids (Telenomus podisi) developing in the eggs of the brown stink bug (Euschistus servus), while unhatched stink bugs experienced lower levels of mortality. One plausible explanation for this was that insecticides might enter parasitized eggs more readily via oviposition wounds. Parasitized E. servus eggs, as well as nonparasitized stink bug (Acrosternum hilare, E. servus, Murgantia histrionica, and Podisus maculiventris) eggs, were examined using electron microscopy. Egg response to perforation by a tungsten probe served as a control. Microscopy images depicted the chorion surface as characterized by a matrix of ridges and micropylar processes in a ring around the margin of the operculum. Observations of oviposition sites showed a “scab” formed where the ovipositor penetrated the chorion, and at sites penetrated by the probe. These formations appeared to be the result of fluids from inside the egg leaking out, drying, and hardening after oviposition or probe perforation, suggesting that the response was not due to substances secreted by the parasitoid. Further, no open wounds or holes were seen to increase the possibility of insecticides entering parasitized eggs.
