| ABSTRACT Predator species under field conditions can face different and variable densities of prey species. This work evaluated the functional response of the neotropical lady beetle Eriopis connexa (Coleoptera: Coccinellidae) subjected to different densities of the aphids Brevicoryne brassicae and Aphis craccivora (Hemiptera: Aphididae). Thus, predation rates were analyzed of fourth-instar larvae and one-day old adults of the lady beetle preying upon the aphids at constant densities of 20, 40, 50, 60, and 70 aphids with 15 repetitions per density. The aphids were offered on 5 cm leaf discs of each plant host. The handling times and attack rates were 0.03 h-1 and 0.27 h-1 for larvae and 0.03 h-1 and 0.15 h-1 for adults fed B. brassicae and 0.59 h-1 and... |

| Sphenophorus levis has become a major pest of sugarcane plantations in Brazil, causing significant losses in productivity. Few studies have been conducted on the spatial distribution of this pest in the field, which is essential for the development of sampling plans. We aimed to characterize the spatial distribution of S. levis in sugarcane, defining a reliable, practical and feasible sampling plan, as well as generating application maps for production areas, allowing for comparison of the consumption of inputs in a conventional system with site-specific application. The study was conducted in areas around Piracicaba, Brazil. First, we conducted sampling to evaluate the best sampling density to characterize the spatial dependence. The results showed that... |

| ABSTRACT Accurate insect specimen identification is usually a crucial first step in a forensic entomological analysis. It is traditionally done by morphological classification using identification keys. However, due to sensibility limitations in the identification of animal species based only on their morphology, new methods have been developed, including species identification by DNA barcodes. The objective of this study was to identify forensically important species of Diptera in Espirito Santo state using DNA barcodes. For this, adult flies were collected in Espirito Santo, Southeast Region of Brazil. After DNA extraction, COI gene was amplified and sequenced. All sequences were matched to BOLD platform and alternatively to GenBank MegaBLAST. As result,... |

| Plastron and spiracular features strongly resemble those of Aphelocheirus aestivalis (Fab.), described by Messner et al. (1981). Plastronal foliose hairs, somewhat irregular shaped are regularly distributed in the plastron. Very numerous tiny openigs on sternites an tergites connect platronal air with a subcuticular air film limited internally apparently by a membrane. Aplicated, radial, structure at the proximal end of the tracheae, almost occluding the extremely fine spiracular openings, appear with lesser variations in both species, suggesting close relationships than accepted until now. |

| ABSTRACT: In recent years, white grubs (Coleoptera: Melolonthidae) have become a serious problem in soybean crops Glycine max (L.) Meril in the "Cerrado" of Brazil (Middle-Western Region). The genus Phyllophaga Harris has been suggested by many authors as one of the most serious pests in diverse crops in Latim America. In Brazil, the most important species of this genus occur mainly in the south of the country, and are P. cuyabana (Moser) in soybean and P. triticophaga in wheat. In the "Cerrado" of Federal District and state of Goiás the specimens of the white grub. damaging soybean, were identified as P. capillata (Blanchard). Expensive and systematic yield losses caused by P. capillata have been observed in large soybean commercial areas. Crops sown in... |
