Efficiency of traps in collecting selected Diptera families according to the used bait: comparison of baits and mixtures in a field experiment

Abstract

Traps made from PET bottles were used to assess the efficiency of four baits in terms of the number of individuals for selected Diptera families collecting in Eastern Slovak gardens in summer and autumn. Bait used in traps significantly affected the taxonomical composition of the samples obtained. Moreover, significant differences in bait efficiencies and temporal shift in bait efficiencies were confirmed for the Diptera order and for selected dipteran families. The most effective bait for baited-trap Diptera sampling was beer, followed by wine, meat, and syrup from the summer sampling season. In the autumn sampling season, the wine was most effective, followed by beer, syrup, and meat. For the family Scatopsidae wine, and for the family Platystomatidae, meat were the most effective baits. Drosophilidae were most attracted to beer in summer and to wine bait in autumn.

Selected Diptera families caught with beer traps in the Republic of Mordovia (Russia)

“…Collecting in the Republic of Mordovia was designed to reduce the gap in the knowledge of Diptera and other invertebrates. Very popular, efficient, cheap and simple passive methods of insect sampling are bait traps (e.g., Manko et al, 2019;Dvořák et al 2019). Beer (with various additions and modifications) is very commonly used as bait, attracting especially Diptera, Mecoptera and other insect groups (e.g., Dvořák et al, 2017;Oboňa et al, 2017).…”

“…Catching Diptera using the fermental traps was thoroughly reported by Dvořáková (2008), Dvořák (2014) and Dvořák et al (2017). Fermental traps with baits from a mixture of beer, sugar, honey, and jam have shown their effectiveness in detecting many Coleoptera (MacRae & Rice, 2007;Guarnieri, 2009;Wong & Hanks, 2016;Egorov & Ivanov, 2018), Lepidoptera (El-Sayed et al, 2005;Uehara-Prado & Freitas, 2009;Jakubíková & Kadlec, 2015), Hymenoptera (Dvořák, 2007;Demichelis et al, 2014;Manko et al, 2019;Sorvari, 2019), and Neuroptera (Duelli et al, 2006;Makarkin & Ruchin, 2019).…”

Diptera species, new for the Republic of Mordovia, Russia

“…Nevertheless, the use of the hand held sweepnet net cannot be used alone. The use of various collecting methods often leads to an increase in the knowledge of the species diversity in a study area (Manko et al, 2018;Ebejer & Nicolosi, 2022).…”

The use of simple crown traps for the insects collection

“…According to some other observations, the most effective bait was wine for Scatopsidae (Diptera), beer and wine for Drosophilidae (Diptera). However, no significant difference between baits for Anisopodidae was found (Manko et al, 2018). Grapes and beer turned out to be the most effective baits for capture of Tephritidae species (Bharathi et al, 2004).…”
