Arthropod Pest

Urban trees serve a critical conservation function by supporting arthropod and vertebrate communities but are often subject to arthropod pest infestations. Native trees are thought to support richer arthropod communities than exotic trees but may also be more susceptible to herbivorous pests. Exotic trees may be less susceptible to herbivores but provide less conservation value as a consequence. We tested the hypotheses that native species in Acer and Quercus would have more herbivorous pests than exotic congeners and different communities of arthropod natural enemies. The density of scale insects, common urban tree pests, was greatest on a native Acer and a native Quercus than exotic congeners in both years of our research (2012 and 2016) and sometimes reached damaging levels. However, differences in predator and parasitoid abundance, diversity, and communities were not consistent between native and exotic species in either genus and were generally similar. For example, in 2012 neither predator nor parasitoid abundance differed among native and exotic Acer congeners but in 2016 a native species, A. saccharum, had the least of both groups. A native, Q. phellos, had significantly more predators and parasitoids in 2012 than its native and exotic congeners but no differences in 2016. Parasitoid communities were significantly different among Acer species and Quercus species due in each case to greater abundance of a single family on one native tree species. These native and exotic tree species could help conserve arthropod natural enemies and achieve pest management goals.

O comércio de mudas florestais para a recuperação de áreas degradadas e reflorestamento é crescente e demanda cada vez mais conhecimentos sobre práticas de manejo na produção de essências nativas, adequadas aos padrões ecológicos locais e à legislação ambiental vigente. Entretanto, a comercialização de mudas exóticas ainda é prática comum nos viveiros florestais, não existindo, para a microrregião de Juiz de Fora, MG, informações sobre os tipos de mudas comercializados nos viveiros florestais. Neste estudo foram levantadas as espécies florestais comercializadas em oito viveiros florestais no município de Juiz de Fora, MG, e que abastecem os projetos de reflorestamento na região. As espécies foram identificadas e categorizadas em nativas da Mata Atlântica ou exóticas. Foram encontradas ao todo 147 espécies. Destas, 64 (43,5% do total) foram exóticas, sendo encontradas, com grande frequência (>50%) entre os viveiros, englobando espécies frutíferas com perfil tipicamente comercial, como Psidium guaja), abacate (Persea americana), amora (Morus nigra) e cítricas – laranja, limão e tangerina (Citrus sp.). Também foram registradas algumas espécies consideradas de alto potencial invasor nas florestas Neotropicais, como o Jambo-rosa (Syzygium jambos), comercializada em metade dos viveiros analisados. A presente análise evidencia uma grande produção e comercialização de espécies exóticas de mudas florestais, utilizadas nos projetos de reflorestamento do município, o que não condiz com a legislação florestal vigente e ainda pode ser considerado como grande risco em potencial para invasão biológica.
