@article{nelson_burrack_sorenson_2020, title={Arthropod carrion influences plant choice, oviposition, and cannibalism by a specialist predator on a sticky plant}, volume={45}, ISSN={["1365-2311"]}, DOI={10.1111/een.12787}, abstractNote={1. Dead arthropods, entrapped by trichomes on plant surfaces, are an underappreciated form of plant‐provided food. Specialist predatory arthropods able to manoeuvre on plants covered in trichomes facultatively scavenge on the alternative food resource, increasing their abundance and reducing plant damage by herbivores.2. This protective mutualism dependent on arthropod carrion has been demonstrated in several plant species, but the mechanisms driving the increase in predator abundance have not been identified. Through a series of greenhouse and laboratory experiments, the effect of arthropod carrion on predator behaviour was assessed.3. The predatorJalysus wickhamipreferredNicotiana tabacumplants augmented with arthropod carrion, spending significantly more time and laying more eggs on those plants than plants without arthropod carrion.4. Under lowJ. wickhamidensities, arthropod carrion did not reduce egg cannibalism by adults. Under high densities, egg cannibalism byJ. wickhamiadults was reduced in the presence of arthropod carrion, but cannibalism by fifth instars was not.5. Arthropod carrion may be utilised by a wide range of predatory arthropods that facultatively scavenge, and this research demonstrates its potential for influencing arthropod–plant and arthropod–arthropod interactions.}, number={2}, journal={ECOLOGICAL ENTOMOLOGY}, author={Nelson, Peter N. and Burrack, Hannah J. and Sorenson, Clyde E.}, year={2020}, month={Apr}, pages={182–189} }

Direct defenses, in the form of chemical and morphological components that inhibit pest damage, underlie host plant resistance, while indirect defenses including food provisioning and semiochemical production, improve biological control. Interactions between the two defensive strategies may be disruptive, complementary, or synergistic and are an important consideration for effective pest management programs. Glandular trichomes are plant structures that inhibit or entrap arthropods, protecting plants against herbivores, potentially at the cost of reducing natural enemy efficacy. Glandular trichomes may also contribute to indirect defense, as predatory arthropods adapted to “sticky” surfaces scavenge on entrapped arthropods. Scavenging increases predator abundance and reduces plant damage; this protective mutualism has been demonstrated with multiple sticky wild flowers but has not been assessed in an economically important plant, such as tobacco. We augmented dead arthropods (carrion) on tobacco plants grown under conditions similar to commercial production and assessed tri-trophic interactions. Carrion augmentation increased predator abundance, reduced damage to reproductive structures, and increased leaf yield, but did not reduce pest densities. We determined that systemic insecticide use did not affect carrion entrapment on tobacco plants. Review of the literature revealed that a variety of economically important plants entrap arthropods on their surfaces, indicating this mutualism has potential for development into a conservation biological control tactic.}, journal={BIOLOGICAL CONTROL}, author={Nelson, Peter N. and Burrack, Hannah J. and Sorenson, Clyde E.}, year={2019}, month={Oct} }

We measured the effect of systemic imidacloprid on J. wickhami in field experiments during 2015 and 2016 by surveying its abundance, the abundance of its prey; the pests Heliothis virescens (Fabricus), Manduca sexta L., and Manduca quinquemaculata (Haworth, 1803); and other predatory arthropods in the agro-ecosystem. Systemic imidacloprid applications did not reduce J. wickhami abundance nor increase the abundance of H. virescens, M. sexta, and M. quinquemaculata, indicating natural control was not affected. J. wickhami abundance was positively correlated with the abundance of prey and predators from another feeding guild, suggesting species interactions have significant implications for the predators.}, journal={CROP PROTECTION}, author={Nelson, Peter N. and Burrack, Hannah J. and Sorenson, Clyde E.}, year={2019}, month={Apr}, pages={15–20} }
