Relação Entre Tempo e Besouros em Mata de Cocal

Abstract

Recebido em 5 de Setembro de 2015 -Aceito em 24 de Agosto de 2017/ ResumoO estudo dos fatores temporais na flutuação populacional dos besouros é de fundamental importância para a compreensão da variação que ocorre em sua população. Assim, analisou-se relação entre tempo e flutuação populacional de coleópteros em Mata de Cocal no município de Teresina-PI no período de agosto de 2011 a julho de 2012. Coletaram-se besouros semanalmente em 12 armadilhas pitfall sem atrativos. Confirma-se correlação canônica entre o conjunto de registro de ocorrência mensal da flutuação populacional das famílias Scarabaeidae, Carabidae, Tenebrionidae, Curculionidae, Bolboceratidae, Histeridae e Chrysomelidae e o conjunto de dados mensais de insolação, de precipitação pluviométrica, da umidade relativa do ar e da temperatura média, com magnitude de 0,99, Qui-Quadrado igual a 66,62, com 28 graus de liberdade e o correspondente p-valor igual a < 0,0001. Significativamente (p < 0,0001), houve correlação canônica positiva entre os dados da insolação (0,81) e da precipitação pluviométrica (0,45), e negativa da umidade (-0,75) e da temperatura (-0,21) ao conjunto dos registros de ocorrência mensal da flutuação populacional de famílias de coleópteros. Deste modo, a flutuação populacional da comunidade de besouros é regida predominantemente pelas variáveis temporais da região em que se encontram e que a sua presença é estacional e condicionada por parâmetros meteorológicos, principalmente insolação e umidade relativa do ar.

Relationship Between Meteorological Conditions and Beetles in Mata de Cocal AbstractStudy the meteorological factors is important to understand beetles population dynamics. So this study examined the relationship between meteorological conditions and the Coleptera population fluctuation in Mata de Cocal in Teresina-PI city from August 2011 to July 2012. Insects were collected weekly in 12 pitfall traps unattractive. It is confirmed canonical correlation between the monthly occurrence record in the families population fluctuation-Scarabaeidae, Carabidae, Tenebrionidae, Curculionidae, Bolboceratidae, Histeridae and Chrysomelidae-in the group of monthly data of insolation, pluviometric precipitation, relative humidity and temperature, with a magnitude of 0.99, chi-square equal to 66.62 with 28 degrees of freedom and p-value corresponding equal to < 0.0001. Significantly (p < 0.0001) there was positive canonical correlation between insolation data (0.81) and pluviometric precipitation (0.45), and negative for humidity (-0.75) and temperature (-0.21) in the monthly occurrence record of the group these families. In this way the population fluctuation and governed predominantly by regional variables and their presence is conditioned by meteorological parameters, principally insolation and humidity.

Diversity of Coleoptera in Maize Crops (Zea mays L.) and a Secondary Succession Area in Paraíba, Brazil

“…In arid regions, they show an important ecological role as detritivores and as a source of food for several vertebrates (Crawford, 1981;Ruiz & Caballero, 2014). Tenebrionids feed on decomposing plant or animal matter, while some larvae inhabit the soil feeding on roots and seeds (Gonçalves, 2017). The Lagria villosa species, a Tenebrionidae, is widely distributed in Brazil, mainly in areas of crops, such as maize, beans, and soybean (Macari, 2013).…”

Relationship between neoathyreus sp and weather

“…It is observed that the individuals of the identified species occupy a functional position or biological position within the ecosystem in which they are inserted. According to Gomes Gonçalves 3 this comprises what the specimens represent in the overall picture of the ecosystem, what they do and how they do it. Browne & Scholtz 6 describe that most species of the Bolboceratidae family dig holes to lay their eggs.…”

Beetles and Meteorological Conditions: A Case Study

“…Coleopteran insects, which they are popularly known as beetles, are important indicators of the environment quality, as they are susceptible to climatic variations and occupy a habitats diversity [1][2][3]. Among the beetles, the family Curculionidae Latreille, 1802, is a very important group present in forest ecosystems due to the role of wood deterioration they make.…”

“…Among the beetles, the family Curculionidae Latreille, 1802, is a very important group present in forest ecosystems due to the role of wood deterioration they make. 1 Insects like all living beings are subject to the nature forces, so there may be an influence that can inhibit or favor the species certain development. For example, the hottest and driest events on El Niño are having an alarming effect on biodiversity in the Amazon Rainforest, contributing to the reduction of insects in the Amazon and across the globe 2 [4].…”

Intense droughts and forest fires during the last El Niño climatic phenomenon, combined with human disturbances -deforestation and 1 Curculionids are known as Rüsselkäfer or Rüssler in German, charançon in French and weevil in English.…”
