“…In the last decades, there has been a fast increment in the areas reforested with species of Pinus in Brazil, introduced mainly from the United States and Australia (Lázzari et al, 2004). The Pinus species planted in Brazil account for 20.7% of all area planted with trees (Indústria Brasileira de Árvores, 2014).…”

“…The attacked trees show retarded development, needle shedding, branch twisting, and abundant production of honeydew that favors sooty mold development, affecting photosynthesis. Lázzari et al (2004) listed the following species occurring in Brazil: Cinara maritimae (Dufour, 1833); Cinara piniformosana (Takahashi, 1923); Cinara tujafilina (Del Guercio, 1909); Cinara fresai Blanchard, 1939;Cinara pinivora (Wilson, 1919); and Cinara atlantica (Wilson, 1919).…”

-Special attention should be given to forest plantings in order to minimize the probability of exotic pest introduction and, consequently, of production losses. The objective of this review was to present, under a historic perspective, the main exotic insects that harm the Brazilian forest sector. Therefore, to better describe the phytosanitary context of introduced forest pests in Brazil, the main information regarding these insects was gathered here. Introduced species and species with a risk of introduction were listed. The following species were registered: 12 exotic introduced species related to eucalyptus, non-quarantine; 9 species related to pine, one quarantine; and 1 species related to teak, quarantine. Overall, the core problems for 57 pest species were addressed, followed by projections on current risks and priorities. Biological control programs and their respective agents were also mentioned. For eucalyptus plantations, the species belonging to the genera Ophelimus and Leptocybe are priorities and should be emphasized. Regarding pine species, the main current concerns are Bursaphelenchus xylophilus (transmitted by species of Monochamus), Rhyacionia frustrana, and Dendroctonus frontalis. Better risk management requires reinforcement of phytosanitary inspections and constant refinement of contingency plans, whose actions include monitoring by visual sampling, employment of sentinel plants, and preventive breeding programs aiming at pest resistance.Index terms: exotic pest, forest pest, forest sector, invasive species, pest resistance, quarantine. Um artigo de revisão sobre pragas florestais introduzidas no BrasilResumo -Atenção especial deve ser dada a plantações florestais para minimizar a probabilidade de introdução de pragas exóticas e, consequentemente, as perdas de produção. O objetivo deste artigo de revisão foi apresentar, sob uma perspectiva histórica, os principais insetos exóticos que ameaçam o setor florestal brasileiro. Portanto, para melhor descrever o contexto fitossanitário das pragas florestais introduzidas no Brasil, foram compiladas as principais informações sobre esses insetos. Espécies introduzidas e aquelas com risco de introdução foram listadas. Foram contabilizadas: 12 pragas exóticas introduzidas, relacionadas a eucaliptos, sem status quarentenário; 9 espécies relacionadas ao pinus, uma quarentenária; e 1 espécie relacionada à teca, quarentenária. Ao todo, foram abordados os problemas centrais para 57 espécies, acompanhados de projeções sobre risco atual e prioridades. Programas de controle biológico e seus respectivos agentes também foram citados. Para os plantios de eucaliptos, as espécies pertencentes aos gêneros Ophelimus e Leptocybe são prioritárias e devem ser enfatizadas. Quanto às espécies de pinus, as maiores preocupações são Bursaphelenchus xylophilus (transmitida por espécies de Monochamus), Rhyacionia frustrana e Dendroctonus frontalis. Um melhor gerenciamento de risco requer reforço de inspeções fitossanitárias e constante refinamento dos planos de conting...

“…The G.duodenalis is transmitted through a thick-walled cyst (8-14 μm). Up to 24 cysts/L have been reported in drinking water (20,21,22), 87 cysts/L in soil (11,23), 0.0087 cysts/L in air (23), and 40 cysts/L in leafy vegetables (Lanata, 2003). Giardia cysts have been tracked mainly in water.…”

Giardia duodenalis has been reported in different sources such as water, human stools, animal stools, vegetable farms and markets and soil of public places. However, different assemblages of G.duodenalis harboured in riverbed sediments have not yet been investigated. Thus, in this study, we quantified and genetically characterised G.duodenalis harboured in the water column and the riverbed sediment of the Apies River to cross this frontier of the unknown in freshwater sediment. Enumeration of G. duodenalis cysts was performed by epifluorescence microscopy observation and quantitative polymerase chain reaction (qPCR). Genetic characterisation was achieved by next-generation sequencing (NGS) using the β-giardin gene and bioinformatics analysis of the NGS data. Results obtained through epifluorescence microscopy revealed a prevalence rate of 87% (140/160) of G. duodenalis cysts in river water, which was higher than that observed in riverbed sediments (78%, 125/160). However, the qPCR assay showed that gene copies of G. duodenalis, which ranged between 3.27 log10 and 7.26 log10 copies/L in re-suspended riverbed sediments, and between 0.49 log10 and 3.95 log10 copies/L in river water Genetic characterisation revealed six and seven assemblages in river water (A, B, C, D, E and F) and riverbed sediment (A, B, C, D, E, F and G), respectively. Both matrices carried similar sub-assemblages belonging to assemblages A (AI, AII and AIII) and B (BI, BII, BIII, BIV and BV), whereas riverbed sediment carried an additional sub-assemblage BX belonging to the assemblage B. The present genetic characterisation results suggest that Apies River water and its bed sediment harbour considerable quantities of G. duodenalis cysts that may cause infections in humans and animals if ingested. Consequently, monitoring of both the water column and respective bed sediments for the presence of G. duodenalis is justified to develop strategies for the protection of public health. This study also calls for urgent identification of point sources that are responsible for the contamination of this freshwater source and its sediment.
