Foraging choice and replacement reproductives facilitate invasiveness in drywood termites

All highly cryptic drywood termites derive their food and water from a single piece of wood. Despite the fact that most species share the same life cycles, only a few have become invasive tramp species. Variation in production of replacement reproductives and food size choice were determined for nine species of the important drywood genus Cryptotermes in a test with two different sized wooden blocks. Four native, non-pest species produced one or two reproductives, gnawed short tunnels and chose large blocks; four tramp pest species produced three or four reproductives, gnawed long tunnels and two species chose small blocks whereas the other two species chose both blocks; the ninth species, a native pest, was similar to tramp species. Longer tunnels and more replacement reproductives corresponded with pest status, acceptance of small blocks with tramp status. Although counter-intuitive, the foraging acceptance or preference for small blocks of wood corresponds with higher propagule pressure and an increased chance of (unwitting) human assisted transport, and therefore may be an important factor in determining tramp status of drywood termite species.

-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...
