“…Lo anterior, podría explicar la alta abundancia de escolítidos y platipódidos en los dos primeros estratos, contrastando con las especies de bostriquidos que fueron más abundantes a 12 m de altura en el interior de la selva. Resultados similares fueron obtenidos por Gerónimo-Torres et al (2021) en un manglar y por Peres-Filho et al (2012) en un bosque tropical semideciduo donde evaluaron la altura de vuelo de Bostrichidae, describiendo que las especies Bostrychopsis uncinata (German, 1824) y Xyloprista praemorsa (Erichson, 1847) presentaron una preferencia por alturas de 30 m. Así mismo, Flechtmann et al (1997), afirmaron que los bostriquidos prefieren alturas superiores a los 10 m con relación al suelo. Safranyik et al (2000) mencionan que los escolítidos no muestran preferencia por un estrato en particular, sin embargo, Gerónimo-Torres et al, (2021) sugieren que existe preferencia en las alturas de vuelo de algunas especies, lo cual concuerda con nuestros resultados al capturar especies en solo uno de los estratos evaluados, que no fueron capturadas en otro estrato.…”

Background. In tropical ecosystems, a great diversity of bark beetles and borers can be recognized, however, this diversity could be underrepresented due to the fact that the studies have been carried out mostly below 2 m in height, which makes it necessary to study them more widely and effectively. Objective. To analyze the vertical distribution of Scolytinae, Platypodinae (Curculionidae) and Bostrichidae at the edge and interior of a tropical forest in Tabasco, Mexico. Methodology. The study was carried out in the high evergreen rainforest of the Sierra el Madrigal in the municipality of Teapa, Tabasco, Mexico. The capture of insects was carried out with flight interception traps baited with 70% ethanol at three different heights: 1.5, 6 and 12 m. Results. The diversity index (1D) showed that the greatest diversity at the edge and interior of the forest is at 1.5 m. However, the traps at the edge located 12 m high captured the greatest richness, and the maximum richness in the interior was recorded at 1.5 m. Stratification of species richness was presented at the edge and interior of the forest. Statistical differences in abundance were found between the evaluated heights: at the edge, these occurred in January, April, October and November; and in the interior, in April. According to the diversity estimation (1D), statistical differences were presented in the months of April and October at the edge of the vegetation, and in the interior in March, April and June. Implications. The results provide a broader picture of the vertical distribution of the insects studied here, which are important in the dynamics of forest ecosystems. Conclusion. The diversity and abundance of insects change over time, and that more detailed studies are lacking to know the degree of variations associated with environmental variables.

“…Neste contexto, o estudo da altura de voo dos insetos possibilita avaliar a distribuição vertical das possíveis injúrias, sendo utilizado na definição de uma ferramenta de monitoramento, auxiliando na adoção de medidas preventivas para o manejo de insetos-praga (Peres Filho et al, 2012;Bertim, 2013). Este trabalho tem por objetivo realizar um levantamento qualitativo (espécies) e quantitativo (abundância) dos coleópteros presentes em um povoamento de Pinus taeda L., caracterizando e delimitando a altura preferencial de voo das principais espécies associadas ao povoamento.…”

O padrão de voo dos insetos pode ser considerado um importante fator biológico no manejo de potenciais insetos-praga. Deste modo, este trabalho objetivou verificar a altura preferencial de voo dos coleópteros associados a um plantio de Pinus taeda L pertencente ao Centro de Pesquisa em Florestas, em Santa Maria, Rio Grande do Sul. Para isto, foram instaladas armadilhas de interceptação de voo distribuídas nas alturas de 0,5; 1,0; 1,5; 2,0; 2,5; 3,0; 3,5; 4,0; 4,5; 5,0; 5,5 e 6,0 metros acima da superfície do solo, com três repetições e com um espaço de 30 metros entre as repetições. Foram coletados 570 indivíduos, distribuídos em 34 famílias e 116 espécies, com o acme populacional no início de novembro de 2011. As famílias Cerambycidae, Curculionidae, Trogossitidae e Scarabaeidae apresentaram a maior abundância. Euetheola humilis (Burmeister, 1847) destacou-se, com 42 indivíduos amostrados no período de novembro de 2011 a maio de 2012, predominantemente, nas alturas de 3,5 m, 4,5 m e 5,0 m. Não foram encontradas diferenças estatísticas entre as diferentes alturas e a abundância total de coleópteros, demonstrando que, neste estudo, os insetos da Ordem Coleoptera não possuem preferência por uma altura de voo em povoamento de Pinus taeda.

“…These traps may contain substances that are attractive to ambrosia bettles, such as aggregation pheromones and/or monoterpenic or alcoholic compounds (Romero et al 2007), in order to increase their attractive power. In Brazil, ethanol is the most widely used substance as an attractive bait in Scolytinae surveys (Dorval et al 2004, Müller and Andreiv 2004, Rocha et al 2011, Peres Filho et al 2012, although the use of host logs as an attractive bait has also been successfully used Gaspareto 1997, Flechtmann et al 1999).…”

Trap models for Scolytinae generally use attractive bait-holders and a collector with ethanol to store the insects. The aim of this paper was verify if the ethanol in the container insect collector can be used as an attractive substance, without need of an extra compartment. The study was carried out in Cuiabá, state of Mato Grosso, Brazil, between June 2009 and May 2010 in stands of Eucalyptus camaldulensis, Eucalyptus urophylla x Eucalyptus camaldulensis, Eucalyptus urophylla x Eucalyptus grandis and native cerrado. Eight escolitídeo-curitiba model traps were installed in each environment, four with 96% ethanol bait holders and the others without attractive. In all traps 70% ethanol was used in the insect collecting container. In the bait traps 2,246 insects and 2100 insects were collected in the no bait, totaling 4,436 insects distributed in 13 genus and 24 species. The use of traps with ethanol baits had no significant effect on insect collection during the evaluated period and regardless of the environments.
