The use of simple crown traps for the insects collection

Abstract

The paper presents data on the use of simple crown traps for studying the insect fauna. The crown trap is a five-litre plastic container with a window cut out on one side of it at a distance of 10 cm from the bottom. The height of the trap location is from 2 m to 10 m from the soil surface. Fermenting beer, various dry wines with the addition of honey, jam or sugar were used as bait. It turned out that crown traps are an effective way to study the insect fauna of the upper layers of forests. During the field seasons of 2018-2019, specimens of the following 12 insect orders were caught in crown traps: Blattoptera,

New records of Diptera from the Republic of Mordovia, Russia

“…The material for this article was collected in 2019-2020 mainly on the territory of Mordovia State Nature Reserve. We used beer traps (Ruchin et al, 2020) and nets for collecting.…”

Checklist of the Coleoptera of Mordovia State Nature Reserve, Russia

“…In order to collect a representative material, the entire range of entomological field research methods were used included various traps such as pitfall traps, light traps, simple crown traps, flight interception traps, cow manure-baited pitfall traps, rodent burrow pitfall traps ( Golub et al 2012 , Egorov and Semishin 2016 , Ruchin et al 2020 ).…”

Usage of Fermental Traps for Studying the Species Diversity of Coleoptera

“…The traps are a plastic 5-liter container with a window cut out in it on one side at a distance of 10 cm from the bottom. With the help of a load, a rope with a tied trap was thrown onto a tree branch at a height of 5 to 12 m from the soil surface [46,49]. As bait, fermenting beer, white and red dry wine was used with an addition in the form of honey, jam or sugar.…”

“…Traps with baits made of fermenting liquids, such as wine, molasses, beer, with the addition of bananas, apples, sugar and other natural fillers have proven effective in detecting many Coleoptera families [35,36,37,38,39,40,41,42,43]. Previously, a mixture of beer with sugar, honey and jam was successfully used as bait [44,45,46]. Using such original and unusual collection methods, it is possible to find new species not only for the region, but also for science [47,48].…”
