“…The host plant lists that indiscriminately include all host plant records become rapidly dominated by marginal hosts and errors committed by either herbivores or ecologists. A more robust definition of monophagous species, that is, species with at least 90% of individuals feeding on a single host species (Thomas 1990;Tavakilian et al 1997;Novotny et al 2002a) may be more legitimate.…”

Host specificity of insect herbivores in tropical forests

Studies of host specificity in tropical insect herbivores are evolving from a focus on insect distribution data obtained by canopy fogging and other mass collecting methods, to a focus on obtaining data on insect rearing and experimentally verified feeding patterns. We review this transition and identify persisting methodological problems. Replicated quantitative surveys of plant-herbivore food webs, based on sampling efforts of an order of magnitude greater than is customary at present, may be cost-effectively achieved by small research teams supported by local assistants. Survey designs that separate historical and ecological determinants of host specificity by studying herbivores feeding on the same plant species exposed to different environmental or experimental conditions are rare. Further, we advocate the use of host-specificity measures based on plant phylogeny. Existing data suggest that a minority of species in herbivore communities feed on a single plant species when alternative congeneric hosts are available. Thus, host plant range limits tend to coincide with those of plant genera, rather than species or suprageneric taxa. Host specificity among tropical herbivore guilds decreases in the sequence: granivoresO leaf-minersOfructivoresOleaf-chewersZsap-suckersOxylophagesOroot-feeders, thus paralleling patterns observed in temperate forests. Differences in host specificity between temperate and tropical forests are difficult to assess since data on tropical herbivores originate from recent field studies, whereas their temperate counterparts derive from regional host species lists, assembled over many years. No major increase in host specificity from temperate to tropical communities is evident. This conclusion, together with the recent downward revisions of extremely high estimates of tropical species richness, suggest that tropical ecosystems may not be as biodiverse as previously thought.

The genus Ommata is reviewed and divided into four genera: Ommata sensu strictu, Acatinga Leiva & Tavakilian, 2004), comb. nov.; A. quinquemaculata (Zajciw, 1966), comb. nov.; Pyrpotyra albitarsis (Galileo & Martins, 2010), comb. nov.Keywords: New genera; New species; Revision, Taxonomy. IntroduçãoNo primeiro trabalho da série "Contribuição para o estudo dos Rhinotragini", todos os subgêneros de Ommata White, 1855 foram considerados gêneros distintos e Agaone Pascoe, 1859 foi revisto.Neste segundo trabalho sobre os Rhinotragini Thomson, 1860, tratamos de Ommata, visando uma revisão geral da tribo que, com algumas exceções (e.g., Monné & Magno, 1988;Giesbert, 1991), permanece pouco estudada e com inúmeros problemas, particularmente na alocação das espécies em gêneros. Em muitos casos, as espécies incluídas em alguns gêneros não possuem os caracteres que permitiriam sua inserção, o que demonstra claramente a fragilidade do conhecimento do grupo. Ommata é um dos gêneros que engloba espécies com caracteres muito distintos, que permitem dividi-lo em vários gêneros.Monné & Bezark (2009)
