Aranhas e ácaros predadores em copas de tangerineiras Montenegrina, mantidas sob manejo orgânico, em Montenegro, RS

Abstract: -A survey was conducted to study the spider and predatory mite fauna occurring in the canopies of tangerine trees (Citrus deliciosa Tenore, cultivar Montenegrina) of an organically managed orchard, at Montenegro County, RS. During a year, fortnightly, 24 randomly trees were selected and sampled in two canopies areas, by using a sheet of white cloth (1 m 2 ). A total of 3,129 arachnids were collected, being 2,559 spiders and 570 mites. Based on the adults, 53 species of Araneae were recognized, belonging to eig… Show more

“…The assemblage was characterized by the predominance of hunting over weaving spiders, similar to the results of Battirola et al (2004Battirola et al ( , 2016, Castilho et al (2005), Sena et al (2010), and Morais et al (2007). The great variety of guilds present in the assemblage demonstrates the share and the lower overlapping of niches by the spiders.…”

“…Regarding the composition of the spider assemblage, Anyphaenidae, Pisauridae, Araneidae, and Salticidae were the most representative taxa, as was already observed in the Pantanal (Santos et al, 2003;Battirola et al, 2004Battirola et al, , 2016, and in other ecosystems (Morais et al, 2007;Carvalho & Avelino, 2010;Sena et al, 2010). The assemblage was characterized by the predominance of hunting over weaving spiders, similar to the results of Battirola et al (2004Battirola et al ( , 2016, Castilho et al (2005), Sena et al (2010), and Morais et al (2007).…”

“…Considerando que esses valores podem ser afetados pela época do ano em que as coletas ocorreram e as técnicas utilizadas, é provável que o período em que a pesquisa foi realizada tenha coincidido com os meses do ano em que os jovens das espécies de aranhas encontradas nas parreiras estão eclodindo de seus ovos. Em ambientes tropicais essa proporção é de 60-70% (SCHARFF et al, 2003) e a predominância de jovens em relação aos adultos é também um padrão em levantamentos de araneofauna em ambientes agrícolas, com proporções de 56% para cana- de-açúcar (RINALDI et al, 2002), 86,2% em tangerinas (MORAIS et al, 2007), 72,8% em laranjas (OTT et al, 2007), 78,7% no arroz (RODRIGUES et al, 2008 Horner (1975) e pode ser decorrente da dispersão aérea (balonismo) que, em muitas espécies de aranhas, é utilizada pelos jovens (RODRIGUES, 2008).…”
