Semiochemical baited traps of lepidopteran pests of economic importance can deliver reliable data also on wide range of non-target species: case study in the Hajdúság Region of East Pannonian Lowland (East Hungary)

Abstract

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.

Wide Range of Brachyceran Fly Taxa Attracted to Synthetic and Semi-Synthetic Generic Noctuid Lures and the Description of New Attractants for Sciomyzidae and Heleomyzidae Families

“…Between the two lures considered, the semisynthetic bisexual lure (SBL) containing isoamyl alcohol, acetic acid and red wine (1:1:1) was more efficient. The attractivity of this ternary mixture to moths was already known in a wide range of Geometridae, Thiatiridae and Erebidae species and noctuid moths, mainly belonging to the Noctuinae, Xyleninae and Hadeninae subfamilies [ 21 , 26 , 29 , 38 ]. Here, its attractivity to nine dipteran Brachycera families was proven and it is reported here for the first time in the families of Ulidiidae, Sarcophagidae, Calliphoridae, Sciomyzidae, Heleomyzidae and Platystomatidae.…”

“…), the attractivity of many compounds and mixtures was previously tested by us. In these studies, isoamyl alcohol-based and phenylacetaldehyde-based lures showed the highest efficiency [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ].…”

Bisexual lures and their comparison with synthetic sex attractants for trapping Orthosia species (Lepidoptera: Noctuidae)

“…The addition of some other synthetic floral compounds resulted in optimized bisexual attractants for numerous noctuids (Landolt et al, 2001(Landolt et al, , 2006Nagy et al, 2021;Tóth et al, 2019Tóth et al, , 2020. Based on these studies a four-component blend of floral compounds (FLO) was developed, consisting of phenylacetaldehyde, (E)-anethol, benzyl acetate and eugenol, which did attract significant numbers of mainly Plusiinae and Melicleptrinae species (Nagy et al, 2014(Nagy et al, , 2015Szalárdi et al, 2021;Szanyi et al, 2017).…”
