Landscape Effects on Native Bees (Hymenoptera: Anthophila) Captured in Pheromone Traps for Noctuid Crop Pests (Lepidoptera: Noctuidae)

Abstract

Noctuid pests, including tobacco budworm (Chloridea virescens (Fab.)) and bollworm (Helicoverpa zea (Boddie)), are significant pests of southern row crops including cotton (Gossypium hirsutum L.), corn (Zea mays L.), and soybean (Glycine max (L.) Moench.). This pest complex is seasonally monitored through Hartstack traps that are baited with synthetic lepidopteran pheromones across the southern United States. We examined bycatch from the noctuid traps deployed across the Mississippi Delta in 2015, 2016, and 2017 for the presence of bees. The most abundant species collected were honey bees (Apis mellifera L.), bumble bees (Bombus spp.), and long-horned bees (Melissodes spp.); these three genera accounted for 82.4% of specimens collected. We also evaluated the proportion of local- and landscape-level habitats on the abundance and richness of the bees caught as bycatch. The proportion of natural and semi-natural habitat affected the abundance and richness of bees collected at the landscape level, but not at more local scales. Additional research is needed to better understand these interactions between bycatch and landscape factors to minimize non-target collections.

Bumble bee responses to climate and landscapes: Investigating habitat associations and species assemblages across geographic regions in the United States of America

“…(2016) and U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Cooperative Agricultural Pest Survey approved methods for pest surveillance (Cooperative Agricultural Pest Survey [CAPS], 2022). Previous research identified that bumble bees are attracted to pest monitoring traps and suggested that these captures be used to advance knowledge of biodiversity, population fluctuations, and other ecological objectives (Buchholz et al., 2011; Christman, Spears, Strange, et al., 2022; Grocock et al., 2020; Grocock & Evenden, 2020; Parys et al., 2021; Sipolski et al., 2019; Spears et al., 2016, 2021; Spears & Ramirez, 2015; Whitfield et al., 2019).…”

Bumble Bee Responses to Climate and Landscapes: Investigating Habitat Associations and Species Assemblages Across Geographic Regions in the United States of America

“…Bumble bees were collected within pest monitoring traps that were placed by state cooperators in agricultural fields across diverse regions in the USA as part of early-detection surveys for invasive lepidopterans following Spears et al, (2016) and U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Cooperative Agricultural Pest Survey approved methods for pest surveillance (CAPS, 2022). Previous research identified that bumble bees are attracted to pest monitoring traps and suggested that these captures be used to advance knowledge of biodiversity, population fluctuations, and other ecological objectives (Buchholz et al, 2011; Spears and Ramirez, 2015; Sipolski et al, 2019; Whitfield et al, 2019; Grocock et al, 2020; Grocock and Evenden, 2020; Parys et al, 2021; Spears et al, 2016, 2021; Christman et al, 2022a).…”

“…Within agricultural systems, intensification and expansion of high-yielding field crops have led to extensive reductions in landscape composition (i.e., the number and amount of distinct land cover categories) and configuration (i.e., the spatial arrangement of those land cover categories), resulting in landscape simplification (Meehan et al, 2011; Pfeiffer et al, 2019; Nelson and Burchfield, 2021). Landscape simplification often reduces the availability, diversity, and distribution of nutritionally sufficient floral resources and nesting sites for bumble bees (Parys et al, 2021), leading them to be inadvertently extirpated in these agricultural environments (Westphal et al, 2003; Hall et al, 2017; Williams et al, 2012). While bumble bees can fly several kilometers to establish colonies and forage, they are also central place foragers with strong site fidelity (Goulson, 2010; Lepais et al, 2010; Rao and Strange, 2012; Ogilvie and Thomson, 2016).…”

Pheromone Communication of Insects: an Ethological Approach

“…надавали перевагу блакитним пасткам [11]. У дослідженнях з феромонними пастками Hartstack, які не мають кольорових ознак, не відмічалось різниці привабливості для бджіл у порівнянні з білими пастками, тому дослідниками зроблено припущення про існування інших причин окрім візуальних [12].…”
