“…Surveys of H. halys on wild and cultivated woody ornamentals and soybean found higher population densities during growth stages with maturing seeds/fruits suggesting that H. halys tracks host plant phenology (Nielsen and Hamilton, 2009;Martinson et al, 2015). Similar behavior occurs in cultivated fruit trees where populations have been observed to follow peach maturity (Hahn et al, 2017).…”

A diverse diet in polyphagous insects satisfies changing nutritional needs but the choice of host plant may vary throughout the insect and plant life cycle. The behaviors associated with host choice in the immature stages may differ from the egg laying site chosen by the mother. To evaluate this for an important agricultural pest, we looked at host choice over two growing seasons for the invasive Halyomorpha halys. H. halys has a host breadth of over 170 known species in its invaded range and adults can satisfy nutritional needs through a strong dispersal capacity. Nymphs are more limited in their ability to choose host plants and we investigated if they make a choice that differs from the source plant (to simulate maternal choice) and characterized volatile organic compounds that are present during attraction. In a mark-release-recapture experiment we quantified dispersal and host choice by nymphs to four common vegetable hosts throughout the growing season. Applying an attraction index to quantify host choice we identified that nymphs switch host plants depending on host phenology. Plants with maturing fruits were most attractive. Volatile organic compounds were collected from host plants during the same time period. Multivariate and correlation analyses categorized phenol, undecane, decanal, and caryophyllene as compounds associated with host plants during peak attractive periods. Thus, the availability of suitable food and associated olfactory cues appears to be influencing the spatiotemporal distribution of H. halys within the agroecosystem. Exploiting dispersal behavior and olfactory cues may be used to help increase the effectiveness and efficiency of current management practices for this severe and widespread pest.

“…points, which explains the mutual positions of the points" (Illian et al, 2008, p. 3). Point pattern analysis has been successfully used previously in the collection of insect data (see Hahn et al, 2017;Monceau & Thi ery, 2017). Point pattern analysis applies second-order statistics based on the frequency distribution of distances of pairs of points (Wiegand & Moloney, 2014) rather than on the intensity of a pattern (i.e.…”

The importance of tree mixtures to the faunal and floral biodiversity of forests has been documented on many occasions, but little is known about the relationships between single‐tree effects, such as litter distribution and carabid beetles. The aim of the study was to investigate the relationship between the occurrence of carabid beetles and the locations of admixed oak trees within a Scots pine (Pinus sylvestris L.) stand. Individuals of four Carabus species were collected in dry pitfall traps in a pine forest with single admixed sessile oaks [Quercus petraea (Matt.) Liebl.]. The capture–mark–recapture technique was used to differentiate carabid beetles by species, gender (female, male), and development stage (imagines, larvae). Three zones of influence were defined according to the distribution of oak leaf litter. The beetle counts from trap data were transformed to a point pattern by means of a random‐field approach where it is assumed that the beetle count per trap is representative of a specified number of single points in the square surrounding the trap. Spatial patterns specific to species, gender, and development stage were observed relative to the oak tree locations. Females and larvae of C. coriaceus and C. hortensis had a high affinity to the oaks, whereas C. violaceus revealed a negative association to the oak trees. No clear trend could be observed for C. arvensis. It was concluded that single‐tree admixtures of oaks affect the spatial patterns of mobile organisms (e.g. Coleoptera) serving as ecological niches in pine forests.

“…All models with evidence of spatial dependency have an additional parameter called "range". Range is the maximum distance between samples below which spatial autocorrelation is present [34,38], and the range value plays a critical role in determining the adequate sampling distance for an unbiased, independent sampling plan [6,11,15,25,39]. The nugget-to-sill ratio (C 0 /C 0 + C) and nugget were used to determine the degree of aggregation [40], where ratios <0.25, 0.25-0.75, and >0.75 indicated strong, moderate, and weak aggregation, respectively [11,[41][42][43].…”

The hunting billbug, Sphenophorus venatus vestitus Chittenden (Coleoptera: Curculionidae), is an important turfgrass pest, especially in sod farms. S. venatus vestitus larvae feed on the stems and roots of turfgrass. Damaged turfgrass is loosely held together and poses a challenge for machine harvesting. Additionally, the normal growth of turfgrass is affected, especially after winter dormancy. Because S. venatus vestitus larvae are hidden inside the stems or under the soil, larval management is challenging. To improve sampling and management, the spatial distribution patterns of S. venatus vestitus larvae and adults were assessed at four sod farm sites with a history of S. venatus vestitus infestation in central Georgia (USA). The larvae were sampled by soil cores using a hole cutter, whereas adults were collected using pitfall traps for 7 d. The spatial distributions of larvae and adults was analyzed using SADIE and variograms. The SADIE and variogram analyses revealed a significant aggregation pattern for adults, whereas aggregated distributions were detected for larvae with variogram analyses. The average ranges of spatial dependence for larval and adult samples were 3.9 m and 5.4 m, respectively. Interpolated distribution maps were created to visually depict S. venatus vestitus infestation hotspots within the sod farms.
