“…Most studies of gall midge distribution in which the edge effect has been observed were conducted either in temperate regions where midges overwinter, with annual host plants, or both (Kolesik 2000, Hodgson et al 2004. In these cases, crops are replanted each season and infested primarily by midges dispersing from locations outside the Þelds.…”

“…Hodgson et al (2004) observed that most sunßower midge damage was concentrated in sunßower Þeld edges, yet argued that site-speciÞc management was not feasible. Adult sunßower midges have a prolonged emergence and infest and disperse through sunßower Þelds over a relatively long period of time (Hodgson et al 2004). Management using insecticides would require multiple applications, especially if the products used have a short residual time.…”

The blueberry gall midge, Dasineura oxycoccana (Johnson) (Diptera: Cecidomyiidae), is a key pest of rabbiteye blueberry, Vaccinium virgatum Aiton, in the southeastern United States, but it has not been studied extensively and little is known about its ecology and management. Studies were conducted to develop an improved method for monitoring D. oxycoccana adults and to determine the within-field distribution of infestation. Four emergence traps were evaluated in an organic rabbiteye blueberry planting for their effectiveness in capturing D. oxycoccana adults early in the season. These traps included a jar trap, wheat blossom midge trap, petri dish trap, and bucket trap. The petri dish and bucket traps captured the highest numbers of adults in 2007 and 2008, respectively. Both traps had a clear plastic panel coated with adhesive. Adult midges emerging from the soil beneath the traps were caught in the adhesive as they flew up toward the light. Emergence traps are useful for detecting the presence of adults early in the season before larval infestation is apparent in the flower buds. To determine the pattern of midge infestation, flower buds were collected weekly from January to March in 2006 from rabbiteye blueberry plants located in a plot at the southwest border of an existing blueberry planting. There were no differences found in the number of larvae collected from various distances within blueberry rows. However, when flower buds were collected from an isolated rabbiteye plot in 2007 and 2008, D. oxycoccana infestation was not uniform. In both years, the southern border row had a significantly higher number of midge larvae per bud compared with the other rows.

“…The number of R. maxima in symptomatic soybean stems in the field was highest in early July and early August (i.e., larvae from overwintering and first‐generation adults), and with higher numbers on field edges than the field interiors in both years. Such an edge effect has been seen for other cecidomyiid pests of annual host plants, such as the lentil gall midge, Contarinia lentis Aczél, the sunflower midge, Contarinia schulzi Gagné, and C. nasturtii 36–39 . In contrast, an edge effect was not observed in the blueberry gall midge, Dasineura oxycoccana (Johnson), which infests a perennial plant host 36,40 …”

BACKGROUNDSoybean gall midge, Resseliella maxima Gagné (Diptera: Cecidomyiidae), is a pest that impacts soybean yield in the Midwest US. While biological control using parasitoids may be a promising approach for managing this pest, it is crucial to have a deep understanding of parasitism dynamics to ensure effective implementation. We investigated R. maxima parasitism using a combination of three methods: rearing of field‐collected hosts, dissection, and molecular assays.RESULTSWe confirmed parasitism of R. maxima by the recently described wasp Synopeas maximum Awad & Talamas (Hymenoptera: Platygastridae) and used our combinatorial approach to observe the spatial and temporal relationships between R. maxima and its parasitoid in the field. The number of R. maxima adults was greater in symptomatic plants on field edges than the field interior, but such a pattern was inconsistent for parasitism rates. Parasitism rates were generally highest early and late in the season, and lower in the middle of the season when the number of R. maxima was highest.CONCLUSIONIn Minnesota, overall season‐long parasitism rates of R. maxima were low (<2%). To facilitate a wider investigation of the biological control of R. maxima, we designed a protocol for high throughput DNA extraction and real‐time PCR that can be used across a broader geography. Further research should evaluate how parasitism rates by S. maximum could be promoted in production fields.This article is protected by copyright. All rights reserved.

“…Variogram analysis, developed for geology and mining, has more recently been adapted for environmental and ecological studies. It has been used to describe spatial structure of western tarnished plant bugs, Lygus hesperus (Knight), in cotton (Carriere 2006); sunßower midge, Contarinia shulzi Gagne, in sunßower, Helianthus annuus L (Hodgson 2004); coffee berry borer, Hypothenemus hampei Ferrari, and leaf minor, Leucoptera coffeella, in coffee, Coffea arabica L. (Alves et al 2011); and grass thrips, Anaphothrips obscurus (Mü ller), in timothy, Phleum pratense L. (Reisig et al 2011). Results from MoranÕs I and variogram analysis can be used to further analysis, such as kriging interpolation (Alves et al 2011, Reisig et al 2011.…”

Within-Field Spatial Distribution of Stink Bug (Hemiptera: Pentatomidae)-Induced Boll Injury in Commercial Cotton Fields of the Southeastern United States

et al. 2014

Spatial distribution of boll injury caused by stink bugs to developing cotton (Gossypium hirsutum L.) bolls was studied in five commercial fields (≍22 ha each) in 2011 and 2012 to understand variability in boll injury dynamics within fields. Cotton bolls and stink bugs were sampled weekly from a georeferenced grid of sampling points (one sample per 0.40 ha) in each field, but no samples were taken within 30 m of field edges. The inverse distance weighted interpolation, variogram analysis, and Moran's I were used to describe spatial variability of boll damage within the fields. Boll injury was found to be spatially associated at distances ranging from ≍75 to 275 m with an average distance ≍150 m. An exponential variogram model was selected as the best fitting model to describe the spatial association in four of the five fields. Moran's I indicated that spatial association was significant in three of the five fields. The spread of boll injury from stink bugs was gradual in most fields and always exceeded the treatment threshold during the fourth or fifth week of bloom. Capture of stink bugs using a sweep net was inefficient, strongly suggesting that quantifying boll injury is a better sampling method and predictor of stink bug activity when sampling all but the edges of the field. These data suggest that scouts need to sample boll injury from sample locations separated by at least 150 m to assure independence in the central part of large fields. Second, future researchers who plan to use parametric statistical methods could use a 150-m grid, as opposed to a denser grid that would require greater time and effort.
