“…A few of the studies coded in this systematic review focused on the effects of plant volatiles on interactions between other organisms. Most of these investigated the influence of plant volatiles on interactions between herbivores, especially in mating or aggregation mediated via herbivore pheromones, which may be either enhanced or disrupted by plant volatiles (e.g., 17,26,28,62,93,95,139,154,156). It may be generally expected that host plant volatiles enhance sex pheromone activity (125), for example, by indicating that a food source for larvae (and perhaps for adults) is close to a mating site, and this has been demonstrated in longhorn beetles (Coleoptera: Cerambycidae); however, the opposite effect has also been demonstrated, depending on the specific combination of beetle species and host plant, ranging from conifers to oaks (28).…”

Plant volatiles comprise thousands of molecules from multiple metabolic pathways, distinguished by sufficient vapor pressure to evaporate into the headspace under normal environmental conditions. Many are implicated as ecological signals, but what is the evidence—and how do they work? Volatiles diffuse, are carried by wind, and may be taken up by other organisms or degrade with exposure to atmospheric ozone, radicals, and UV light; visual signals such as color are not subject to these complications (but require a line of sight). Distantly related plants—and nonplants—produce many of the same volatiles, yet specific compounds and blends may be distinct. Here, I present a quantitative review of the literature on plant volatiles as ecological signals, illustrating a field that has focused on developing ideas as much as reporting primary data. I discuss advantages and constraints, review recent advances, and propose considerations for primary studies to elucidate particular functions of plant volatiles. Expected final online publication date for the Annual Review of Plant Biology, Volume 74 is May 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…Management of PLRV has historically proven challenging in part due to the propensity of green peach aphids to develop insecticide resistance (Alyokhin et al 2022). Additionally, the usage of broad-spectrum insecticides which have nontarget effects on the natural enemies of aphids can lead to secondary outbreaks, as natural enemies are important suppressors of aphid population growth in potatoes (Weber et al 2022). Lastly, the management of aphid-vectored viruses such as PLRV requires rapid kill or interference with feeding to prevent transmission.…”

Afidopyropen as a potential tool for Potato leafroll virus management in post-neonicotinoid potato production

Potato leafroll virus (PLRV) has been well managed by neonicotinoids since their widespread adoption in the United States, becoming virtually absent from seed and production fields in the Northwest. However, with increasing interest in discontinuing neonicotinoid usage, there is concern that PLRV could enjoy a resurgence in the absence of effective alternative chemistries. We tested the effects of afidopyropen, an insecticide with novel mode of action, on PLRV transmission and the feeding/probing behavior of its primary vector, the green peach aphid (Myzus persicae [Sulzer]). Afidopyropen foliar sprays decreased PLRV transmission by individual green peach aphids relative to water controls: PLRV acquisition from treated potato plants and subsequent transmission was reduced by 89%, and PLRV inoculation by viruliferous aphids to treated potato plants was reduced by 35%. Although electropenetrograph analyses following 4-h recordings of individual aphids on potato plants showed decreases in the total and mean duration of phloem feeding (E) on plants subject to an afidopyropen treatment relative to water, these only trended toward significance. Taken together, these results suggest treatment with afidopyropen can decrease PLRV transmission in potatoes, but that significant changes in feeding/probing might not occur quickly post-exposure. Overall, while the reductions in transmission were not as dramatic as have been observed following neonicotinoid treatments, afidopyropen may be a useful alternative and should be evaluated in field experiments.

“…In particular, this type of biocontrol agent is interesting for storage conditions, where the eggs are laid on the surface of potatoes. Few eggs parasitoids are found on T. solanivora ; one example is the braconid, Apanteles sp., although it does not protect tubers, as this parasitoid does not prevent the growth and feeding of larvae but may reduce the population of the pest in the next generation [ 12 , 16 , 17 ]. The encyrtid ( Copidosoma koehleri ) (Blanchard, 1940) presents the same limitation, despite sometime proving successful under field conditions on common tuber moth, Phthorimaea operculella (Zeller, 1873).…”

The Guatemalan potato moth (Tecia solanivora) is designated a quarantine pest by the European Union, causing severe production losses in potato crops. No effective chemical control alternatives are currently available, and cultural techniques are unable to reduce harvest losses to acceptable levels. With a focus on biological control, two egg parasitoids (Trichogramma euproctidis and Trichogramma achaeae) were selected and evaluated for use under field and storage conditions. Laboratory assays (choice and no-choice) indicated the preference of both parasitoids for T. solanivora vs. Phthorimaea operculella. Trichogramma euproctidis showed the highest parasitic activity for both moths. Analysis of functional response (at 15, 20, 25 and 27 °C) confirmed the high parasitic potential of T. euproctidis. Furthermore, in assays conducted under darkness conditions, T. achaeae was unable to parasitize eggs. However, in semi-field assays, T. achaeae was more efficient in searching for eggs in the soil than T. euproctidis. Based on these results, T. achaeae was selected to be tested under field conditions, and T. euproctidis was selected for testing under storage conditions.
