“…Ready‐made empty dispensers (unloaded, without lure ingredients) were purchased from PÁ‐ME BT. This type of dispenser proved to be very useful in dispensing phenylacetaldehyde‐based lures for a wide range of moths (Tóth et al., 2010, 2012, 2020). This type of dispenser was performing best for A. gamma when compared with two other types with thicker walls (Tóth et al., 2019).…”

In field trapping tests the addition of 4‐oxoisophorone (2,6,6‐trimethylcyclohex‐2‐ene‐1,4‐dione) to the known ternary bisexual lure (consisting of phenylacetaldehyde + benzyl acetate + eugenol) significantly increased catches of the silver Y moth Autographa gamma, an important migratory noctuid pest. Both female and male moths were attracted, supposedly in the natural sex ratio of the local population. Traps baited with the quaternary lure caught 27.9% of the number of moths in traps baited with synthetic sex pheromone (all males), and the two types of lures showed similar seasonal trends when following the quantitative changes in moth flight throughout the whole season. This suggests that the improved quaternary bisexual lure could be efficient enough to yield a new tool for detection and monitoring of A. gamma, resulting in more reliable plant protection decisions based on female catches, and can provide data for studies where the catch of females and data on sex ratio are indispensable.

“…The sampled Noctuidae taxa were identified to species level if possible, according to Varga 2012). The taxonomic list follows the system by Lafontaine and Schmidt (Lafontaine and Schmidt 2010) with modifications of Zahiri et al (Zahiri et al 2012). In the case of subdivision of faunal elements and ecological types (so-called faunal components), the methodology of Varga et al ) was followed.…”

Lepidopteran assemblages were studied at 16 sampling sites in the Hajdúság Region between 2013 and 2020. Although studies targeted development of synthetic phenylacetaldehyde-based and semi-synthetic isoamyl alcohol-based baits for pest monitoring, traps caught 179 species belonging to the Sphingidae, Thyatiridae, Geometridae, Erebidae and Noctuidae families. Most species were pests or widely distributed generalists, but there were also many rare habitat specialists, for example, silvicol species, whose appearance was unexpected in the recently less forested region. The specificity of the two bait types tested differed notably both on family and subfamily levels. Semi-synthetic baits performed better and attracted a wide range of noctuids belonging mainly to the Xyleninae and Noctuinae subfamilies, while synthetic phenylacetaldehyde-based lures showed specificity to Plusiinae subfamilies with lower number of sampled species. Our data fill a gap of knowledge since the fauna studied formerly was nearly unknown and brings attention to the alternative use of volatile traps of agricultural pests in faunistical studies.

Development of a Phytochemical-Based Lure for the Dried Bean Beetle Acanthoscelides obtectus Say (Coleoptera: Chrysomelidae)

The dried bean beetle, Acanthoscelides obtectus, is an economically important, worldwide pest of legume crops including dry beans, Phaseolus vulgaris. Assessment of A. obtectus infestation levels in pre-harvest field crops and post-harvest granaries is difficult to achieve because there is no effective monitoring tool for early detection so that interventions can be deployed as needed. Because A. obtectus is a generic pollen and nectar feeder, we adopted an electrophysiological (EAG) screening approach, using the antennae of female A. obtectus to identify physiologically active, volatile phytochemicals, which could then be investigated for their attractiveness to A. obtectus in laboratory behavioral assays and preliminary field tests. Of the 27 compounds tested in EAG screening, 5 compounds, i.e., methyl anthranilate, methyl eugenol, benzyl alcohol, (RS)-lavandulol, and 2-phenylethanol, elicited stronger EAG responses than the standard (1-phenylethanol). In 4-arm olfactometer bioassays, female A. obtectus preferred the olfactometer arm containing the odor of either methyl anthranilate or benzyl alcohol compared to the solvent control. In preliminary field tests using these 2 compounds as a binary mixture, at least 5 times as many beetles were caught on baited traps compared to non-baited traps. The field data also suggested that benzyl alcohol was primarily responsible for the field activity of the blend. We hypothesize that the attraction of A. obtectus to the combined benzyl alcohol/methyl anthranilate and the single benzyl alcohol baits is connected to the species` nectarand pollen-feeding behaviour and not to its intraspecific communication. To our knowledge, this is the first evidence that A. obtectus behavior in the field can be modified by the deployment of plant-derived semiochemicals.
