Abstract - The objective of this work was to evaluate the sensitivity of different populations of Digitaria insularis to the glyphosate, clethodim, and haloxyfop-P-methyl herbicides, in agricultural areas, and to develop infestation maps based on the responses of these populations. One hundred sixty-one populations suspected of being resistant were evaluated and compared to a susceptible population. When plants displayed three to four tillers, the populations were sprayed with glyphosate (1,000 g ha-1 a.e.), clethodim (108 g ha-1 a.i. + 0.5% mineral oil), and haloxyfop-P-methyl (62.35 g ha-1 a.i. + 0.5% mineral oil); plants without herbicide application were used as the control. The plant populations were classified as susceptible, intermediately resistant (with susceptible and resistant plants), or resistant to the tested herbicides. All populations were susceptible to clethodim; 97.5% were susceptible and 2.5% were intermediately resistant to haloxyfop-P-methyl; and 9.9% were susceptible, 21.1% intermediately resistant, and 68.9% resistant to glyphosate. Glyphosate-resistant populations are homogeneously distributed throughout the evaluated regions. There are no cases of D. insularis multiple resistance in the sampled regions; however, cross-resistance to glyphosate and haloxyfop-P-methyl was detected.
Resumo - O objetivo deste trabalho foi avaliar a sensibilidade de diferentes populações de Digitaria insularis aos herbicidas glifosato, cletodim e haloxifope-P-metílico, em áreas agrícolas, e elaborar mapas de infestação com base na resposta das populações aos herbicidas. Cento e sessenta e uma populações com suspeita de serem resistentes foram avaliadas e comparadas a uma população suscetível. Quando as plantas estavam com três a quatro perfilhos, as populações foram pulverizadas com glifosato (1.000 g ha-1 e.a.), cletodim (108 g ha-1 i.a. + 0,5% de óleo mineral) e com haloxifope-P-metílico (62,35 g ha-1 i.a. + 0,5% de óleo mineral); plantas sem aplicação de herbicidas foram usadas como controle. As populações foram classificadas como sensíveis, resistentes ou intermediárias (com plantas sensíveis e resistentes) aos herbicidas-teste. Todas as populações foram sensíveis ao cletodim; 97,5% foram sensíveis e 2,5% intermediárias a haloxifope-P-metílico; e 9,9% foram sensíveis, 21,1% intermediárias e 68,9% resistentes ao glifosato. Populações resistentes ao herbicida glifosato estão dispersas homogeneamente nas regiões avaliadas. Não há casos de resistência múltipla de D. insularis nas regiões amostradas; no entanto, detectou-se resistência cruzada a glifosato e a haloxifope-P-metílico.

ABSTRACT: The taxonomy of the hitherto unplaced taxon Porosagrotis carolia Schaus, 1929 is evaluated and the name is taken out of taxonomic limbo and combined with Feltia Walker, 1856. Feltia carolia comb. nov., described from a single female specimen, is redescribed, including the first description of the male. Head, thorax and its appendages, and male and female genitalia are illustrated through photographs and line drawings; photographs of the holotype and a distribution map for the species is provided. Additionally, the spatio-temporal occurrence of the species in Rio Grande do Sul was assessed by monthly standardized samplings with light traps from January of 1998 to December of 1999 in ten different physiographical zones of the state. Our results suggest that F. carolia comb. nov. is univoltine and goes through prepupal and pupal estival diapauses. The assessment of the distribution of the species, based on the standardized samplings and specimens deposited in entomological collections, suggests that F. carolia comb. nov. is restricted to the southern Brazilian Campos, a mostly neglected environment discontinuously distributed in mountainous plateaus of the southern Mata Atlântica biome. |
