“…The only well-studied agricultural pest in this regard is the Colorado potato beetle, Leptinotarsa decemlineata (Say), as adults walk into agricultural fields from surrounding habitats (Boiteau et al, 2003). Traps to monitor the abundance and movement of arthropods walking on standing trees in forest ecosystems were used by Bar-Ness et al (2012), Hanula & New (1996), Moeed & Meads (1983), and Pinz on & Spence (2008), and in an agricultural system by Mulder et al (1999).…”

Halyomorpha halys St al (Hemiptera: Pentatomidae) has recently become a major orchard pest in the Mid-Atlantic, USA. Large H. halys populations can develop on wild tree hosts adjacent to orchards, posing an ongoing threat to fruit. Adults and nymphs feed on tree fruit, causing economic injury. Understanding the seasonal patterns of nymphal host use among trees at the orchard-woodland interface may aid the development of integrated pest management strategies for this pest. In laboratory and field experiments, modified versions of published trap designs -'Circle', 'Hanula', 'M&M' (after Moeed & Meads) trapswere compared for their effectiveness for capturing H. halys nymphs walking up and down tree trunks. In the laboratory, second instars were released at the top and bottom of ailanthus (tree of heaven), Ailanthus altissima (Mill.) Swingle (Simaroubaceae), logs and captures were recorded after 24 h. Circle and M&M traps, respectively, were most effective for capturing nymphs walking up and down. In the field, traps were deployed on ailanthus trees next to apple orchards and captures were recorded weekly from 24 July to 11 September 2013. As in the laboratory, Circle and M&M traps captured the greatest number of upward-and downward-walking nymphs. Hanula traps were least effective in both experiments. In the field, 88% of total captures were of nymphs walking up trees. This was at least partially explained by behavioral assays in the laboratory demonstrating that nymphs exhibited negative gravitaxis and positive phototaxis. Stage-specific trends in captures of instars walking up during field sampling were observed. These results suggest that trunk traps can be used to address important ecological questions about seasonal patterns of host use by H. halys nymphs.

“…For this trap, the initial cost of a reusable unit is higher than single‐use trapping techniques, such as sticky and funnel traps, which can cost under A$1 per unit (Bar‐Ness et al . 2012). However, net cost‐benefit for our reusable design improves after each use due to the decrease in ongoing costs (Table 1).…”

Here we describe and test a novel canopy trap design for catching the little fire ant, Wasmannia auropunctata, known as the electric ant in Australia, as part of the National Electric Ant Eradication Program (the program) in North Queensland. As W. auropunctata is known to nest and forage both on the ground and in tree canopies, an effective arboreal trap to monitor their presence is a critical management tool. Our trap design addresses known issues with arboreal sampling such as sample retention, weather and debris proofing, robustness and canopy access. The trap is cost effective and friendlier to the environment compared with single‐use traps, due to its reusability and recyclable or biodegradable components. Field testing carried out in the Cairns region demonstrated that the canopy trap successfully collected ants with minimal non‐ant bycatch. In a known W. auropunctata‐infested area, the canopy trap recorded an 88% sensitivity rate and continues to be used as a surveillance tool within the program. Additional research is required to further evaluate the sensitivity of the canopy trap for monitoring W. auropunctata populations. We believe that the trap has potentially wider applications for arboreal arthropod sampling and can be modified to suit.

“…Experimental design, scientific questions, and management practices should not be determined by the methods and modes of accessing tree canopies. The community of scientists who study the biology of tree canopies originally had to overcome tremendous obstacles and recent developments are both a cause and a consequence of creative methods for accessing tree canopies (Barker and Sutton, 1997). Even today, most people working with trees state that their canopy access is limited and if they had effective and accurate equipment, they would routinely collect samples from the arboreal ecosystem.…”

The arboreal ecosystem is vitally important to global and local biogeochemical processes, the maintenance of biodiversity in natural systems, and human health in urban environments. The ability to collect samples, observations, and data to conduct meaningful scientific research is similarly vital. The primary methods and modes of access remain limited and difficult. In an online survey, canopy researchers (n = 219) reported a range of challenges in obtaining adequate samples, including ∼10% who found it impossible to procure what they needed. Currently, these samples are collected using a combination of four primary methods: (1) sampling from the ground; (2) tree climbing; (3) constructing fixed infrastructure; and (4) using mobile aerial platforms, primarily rotorcraft drones. An important distinction between instantaneous and continuous sampling was identified, allowing more targeted engineering and development strategies. The combination of methods for sampling the arboreal ecosystem provides a range of possibilities and opportunities, particularly in the context of the rapid development of robotics and other engineering advances. In this study, we aim to identify the strategies that would provide the benefits to a broad range of scientists, arborists, and professional climbers and facilitate basic discovery and applied management. Priorities for advancing these efforts are (1) to expand participation, both geographically and professionally; (2) to define 2–3 common needs across the community; (3) to form and motivate focal teams of biologists, tree professionals, and engineers in the development of solutions to these needs; and (4) to establish multidisciplinary communication platforms to share information about innovations and opportunities for studying arboreal ecosystems.
