Use of flight interception traps of Malaise type and Attractive Traps for social wasps record (Vespidae: Polistinae)

Abstract

The literature provides different methodologies for collecting social wasps, including, flight intercept trap type Malaise and Attractive trap, however, there is no consensus on its use. In this respect, the aim of this study was to evaluate the best use of Malaise traps and Attractive trap in biodiversity work of social wasps, and generate a collection protocol for the use of these traps. The study was conducted in the Parque Estadual do Rio Doce, east of the state of Minas Gerais, in the years 2000, 2001, 2002 and 2004 and in the Botanical Garden of the Federal University of Juiz de Fora, located in the southeastern state of Minas Gerais, in years 2011, 2012 and 2013. Were collected 15 species using Malaise traps, and traps Attractive, 26 species of social wasps were collected. Although the negative aspects of both traps are useful complementary methodologies surveys varying social wasps and it is recommended to choose for use in accordance with the logistical field.

The Effect of Forest Fragmentation on Polistinae

“…This method was consisted of running across the pre-existant tracks in the border and interior of the forest, and the capturing of the insects was assisted by an entomological web. The second methodology, the attractive traps, was used with PET bottles, as suggested by Souza et al (2015a). Ten unities were distributed for each fragment in three months -September and October 2017, and March 2018 -being kept in the field for seven consecutive days, in a total of 84 sampling days, being 21 for each fragment.…”

“…The traps were distributed in sites indicated by the researcher, considering the highest possibility if collecting social wasps, such as forest border, close to water courses etc. The bottle-traps were placed in a straight line and hang in the vegetation at 1,5 meters from the ground, with a distance of 10 meters between them and utilizing as bait 250 mL of fresh passionfruit juice (Souza et al, 2015a). At the end of the seventh day after the installation of the traps on the field, the material was sorted with a clamp and a sieve and subsequently accommodated in 70%-pure alcohol, in order to be possible to proceed with the assembling and identification.…”

Occurrence of Social Wasps (Hymenoptera: Vespidae) in a Sugarcane Culture

“…Sampling was carried out through active search from 10:00 to 17:00 during five days in a row each month in random transects within and around the culture. Bait traps were also used, consisting of two-liter polystyrene bottles with three triangular holes (2x2x2 cm) cut at 15 cm from the base, the baits were made from passion fruit juice, honey water or sardine broth (Souza & Prezoto, 2006;Souza et al, 2015). Thirty-six traps were set each month in two transects (East and West) with 18 bottles each (six with sardine broth, six with passion fruit juice and six with honey water).…”

Distância Ótima para Instalação de Armadilhas Atrativas para Captura de Vespas Sociais Neotropicais: uma Projeção Estatística

“…Para a coleta de vespas sociais (Hymenoptera: Polistinae) em uma determinada área, o método mais utilizado é o de armadilhas atrativas, ou seja, são instaladas armadilhas iscadas com algum recurso alimentar, como carboidrato e / ou proteína, que atraem e capturam esses insetos no momento em que estão forrageando (Souza et al, 2015;Barbosa et al, 2016). Neste método, assim como acontece na natureza com frutos maduros e restos de animais, por exemplo, cada armadilha libera substâncias voláteis provenientes da fermentação das iscas num determinado raio (Pareja et al, 2007;Somavilla et al, 2019;Maciel, 2014), atraindo assim as vespas sociais.…”

“…Foram instaladas 40 armadilhas atrativas que, com base na literatura, foram iscadas com suco de frutas, cerveja ou vinho tinto (Maciel et al, 2016) e, como proposto por Souza et al (2015), equidistantes a 10 m e a uma altura de 1,5 m do solo. As armadilhas permaneceram em campo por cinco dias consecutivos ao longo de 12 campanhas realizadas entre novembro de 2015 e maio de 2016.…”
