Noctuids are the main phytophagous pests of gramineae and decisions about its control are based on percentage of defoliation, not considering the level of larval infestation. The objective of this study was to test the sweeping net in the evaluation Noctuidae population and of the principal groups of natural enemies in ryegrass (Lolium multiflorum Lam.), in the morning and at night. The work was conducted in two crops in Salvador do Sul, RS, Brazil. In the first experiment, insects were sampled… Expand
Diversidade dos noctuídeos (Lepidoptera, Noctuidae) em Salvador do Sul, Rio Grande do Sul, Brasil
TLDR
The Noctuidae community in Salvador do Sul, Rio Grande do Sul is described, where the more constant species were noctuids of great economic importance; the accessories were related to specific vegetable groups; the accidentals have their host unknown. Expand
PEST MANAGEMENT Caracterização dos Danos de Spodoptera eridania (Cramer) e Spodoptera cosmioides (Walker) (Lepidoptera: Noctuidae) a Estruturas de Algodoeiro
TLDR
The results validate observations that these two species of Spodoptera are potential pests for cotton and quantify the potential damage of S. cosmioides and S. eridania. Expand
Reproductive biology and longevity of Euplectrus ronnai (Brèthes) (Hymenoptera: Eulophidae)
The larval ectoparasitoid Euplectrus ronnai (Brethes) is one of the components of a species complex that attacks the armyworm Mythimna (Pseudaletia) sequax Franclemont (Lepidoptera: Noctuidae). NoExpand
Tolerância à germinação na espiga em cultivares de trigo colhido na maturação fisiológica
TLDR
Frontana was the most promising cultivar to be used in breeding programs and the use of visual grades as criteria of sprouting in the ears permitted a prompt and accurate evaluation of great number of cultivars without affecting the results of tolerant genotypes selection. Expand
Owlet moths (Lepidoptera: Noctuoidea) associated with Bt and non- Bt soybean in the brazilian savanna.
TLDR
This study compared the richness and abundance of owlet moths (Noctuoidea) associated with Bt and non-Bt soybean, and determined the temporal variations as a function of phenology, and correlated the population variations of the most common species with meteorological variables. Expand
Owlet moths ( Lepidoptera : Noctuoidea ) associated with Bt and non-Bt soybean in the brazilian savanna
The use of GMO expressing Bt toxin in soybean production has increased significantly in the last years in Brazil in order to manage the damage caused by lepidopteran pests. In this study, we comparedExpand
Incidence of Mythimna sequax parasitized in wheat crop
TLDR
This study reported for the first time four Tachinidae species parasitizing W. sequax, and further studies are needed to promote the conservation of these parasitoids in agroecossystem and development biological control programs for management of the wheat armyworm. Expand
[Characterization of the damage of Spodoptera eridania (Cramer) and Spodoptera cosmioides (Walker) (Lepidoptera: Noctuidae) to structures of cotton plants].
TLDR
The results validate field observations that these two species of Spodoptera are potential pests for cotton and are considered species with potential to cause economic damage to cotton plants. Expand
Edge effects on carabid beetles (Coleoptera: Carabidae) between forest fragments and agricultural fields in south‐east Brazil
TLDR
Carabid communities showed high similarity between edge – crop and edge – fragments, and species of Scarites showed the most potential as biocontrol agents of soybean/corn pests. Expand
Carabid beetles (Coleoptera: Carabidae) and biological control of agricultural pests in Latin America
Abstract The well-diversified Latin American agriculture plays an essential role in the economy of that region, through the export of food and agricultural commodities. The region is expected toExpand
