Abstract In both basic and applied studies, quantification of herbivory on foliage is a key metric in characterizing plant–herbivore interactions, which underpin many ecological, evolutionary agricultural processes. Current methods quantifying are slow or inaccurate. We present LeafByte, free iOS application for measuring leaf area herbivory. LeafByte can save data automatically, read record barcodes, handle light dark coloured plant tissue, be used non‐destructively. evaluate its accuracy...
The influence of predator cues on the behaviour prey is well supported in literature; however, a clear understanding how affect variable environmental conditions and over longer time scales needed to better understand underlying mechanisms. Here, we measure odors herbivore colonization, abundance, oviposition, plant damage across two growing seasons. study system consisted Leptinotarsa decemlineata (Colorado potato beetle) as prey, aggregation pheromone live Podisus maculiventris (spined...
Abstract A growing number of studies have manipulated intraspecific plant diversity and found dramatic changes in the densities associated insect herbivores their predators. While these been essential for quantifying net ecological consequences diversity, they less effective at uncovering ways which alters trophic interactions within arthropod communities. We predation risk field a factorial design to reveal how mixture genotypes response an herbivorous beetle ( Leptinotarsa decemlineata )...
Acoustic technology is a potential tool to protect wood materials and eventually live trees from colonization by bark beetles. Bark beetles such as the southern pine beetle Dendroctonus frontalis, western D. brevicomis engraver Ips pini (Coleoptera: Curculionidae) use chemical acoustic cues communicate locate mates host trees. In this study, efficacy of sound treatments on I. entry into tree was tested.Acoustic significantly influenced whether entered logs in laboratory. Playback artificial...

Phloem tissues of pine are habitats for many thousands organisms. Arthropods and microbes use phloem cambium to seek mates, lay eggs, rear young, feed, or hide from natural enemies harsh environmental conditions outside the tree. Organisms that persist within habitat difficult observe given their location under bark. We provide a technique preserve intact prepare it experimentation with invertebrates microorganisms. The apparatus is called 'phloem sandwich' allows introduction observation...
We examined the incidence of bark beetle (Coleoptera: Curculionidae: Scolytinae) colonization and subsequent mortality, presence dwarf mistletoe (Arceuthobium vaginatum subsp. crytopodum) within a rare remnant old-growth stand ponderosa pine. In 2011, 96% old growth trees were remaining with additional dense ingrowth pine (Pinus Douglas ex. Lawson) understory oldest trees. compared to abutting stands pine: low-density seed-tree cut high-density post-1900 second growth. The had levels similar...
Spotted-wing drosophila (SWD), Drosophila suzukii Matsumura (Diptera: Drosophilidae), is an invasive pest of thin-skinned fruits in the United States. Monitoring traps are integral part SWD integrated management, allowing early detection and timely management this pest. An ideal monitoring trap should be easy to use, effective capturing SWD, sensitive selective male which identify due their spotted wings, able predict fruit infestation from captures. Deli-cup-based liquid (grower standard),...

Abstract Prey commonly use volatile chemicals released from predators to infer the level of danger and can enact phenotypic changes increase their chance survival. Because some emit volatiles that are also used in plant defense signaling, there is potential for plants respond predator cues. In Colorado potato beetle, Leptinotarsa decemlineata , spined soldier bug, Podisus maculiventris potato, Solanum tuberosum system, beetle responds aggregation semiochemical, which comprised...
Abstract Podisus maculiventris (spined soldier bug) is a generalist predator studied for its biocontrol potential. This species has large dorsal abdominal gland (DAG) that releases pheromones can also be important semiochemicals other organisms. Despite our growing understanding of development, the conditions elicit are largely unknown. To determine if male age or development affects chemical composition and release behavior, we dissected adult bugs profiled DAG 1, 7, 14 d post-eclosion....
