Insetos galhadores associados a duas espécies de plantas invasoras de áreas urbanas e peri-urbanas

Abstract: ABSTRACT. Galling insects associated with two species of ruderal plants in urban and peri urban areas. Insects have been considered as important bioindicators of environmental changes and habitat quality. In spite of its sessile habit, easy localization, abundance and host specificity, insects that induce galls have not been utilized in studies of this nature. It was investigated the suitability of gall-inducing insects associated to two ruderal host plant species (Baccharis dracunculifolia and Vernonia polyan… Show more

“…Ao comparar a diversidade de galhadores entre biótopos urbanos e rurais Julião et al (2005) não encontrou diferenças na riqueza de galhadores, porém a abundância desses insetos foi influenciada pela paisagem, sendo as áreas com menos impactos as que apresentaram maiores abundâncias. Segundo Pereira et al (2003), o número de espécies é influenciado pelo uso prévio da área, com forte redução com o aumento da degradação ambiental.…”

“…Julião et al (2005), em estudos com duas espécies vegetais invasoras em habitats com diferentes históricos de uso, encontrou maior riqueza de insetos galhadores associada a Baccharis dracunculifolia em ambientes pouco urbanizados. Os autores também relacionaram a porcentagem de cobertura vegetal dos habitats com a fauna de galhadores e encontraram uma forte e positiva relação entre os dois fatores, resultado similar ao encontrado no presente estudo no qual a riqueza de galhas foi maior em ambientes preservados.…”

“…Among these, there is a wide prevalence of galls induced by Diptera, were recorded over a thousand morphotypes, mainly driven by species of family Cecidomyiidae (Maia et al 2008), which represent the group of predominantly insect galls in all zoogeographical regions of world (Gagné 1994). Julião et al (2005) discusses the use of such groups as bioindicators because they are easy objects of study, due to the bodies remain locatable for much of their life cycle and are abundant in their hosts, although they are still few studies on the characterization of this fauna (Lara & Fernandes 1996), despite efforts to work on characterization of galls and gall makers in areas of restinga (Maia 2005), Cerrado, rupestrian fields, semidecidual forest in the states of São Paulo and Minas Gerais (Urso-Guimarães & Scarelli- Santos 2006, Urso-Guimaraes et al 2003, Lara & Fernandes 1996.…”

According to Fernandes et al (1995), the sampling during a weather station is sufficient to evaluate the number of galls per habitat, because of the absence of statistical difference in the results obtained, which were conducted in two seasons, dry and rainy seasons.…”
