| Resumo: O Brasil é o maior produtor mundial de citros. Entretanto, a evolução da quantidade nacional produzida de laranja e limão vem decrescendo nos últimos cinco anos, retornando a valores de 2009. Problemas fitossanitários podem estar contribuindo para esse declínio, tais como a doença Huanglongbing. Diaphorina citri é vetor da doença e vem contribuindo na dispersão de HLB e em danos nas plantas. Por essa razão, ações de controle biológico utilizando parasitóides exóticos para auxiliar no controle vêm sendo prospectadas como alternativas. Entre eles, citam-se pesquisas com Diaphorencyrtus aligarhensis, que requerem ninfas de D. citri e hospeiros-planta. Trabalhos técnicos apontaram a maior disponibilidade de ninfas de D. citri em limão-cravo. Esse... |

| The food cycle and geographical variation of Dysdercus diet were studied as strategy elements of trophic resources exploitation. The species used were D. fulvoniger, D. maurus, D. mendesi and D. ruficollis. A random sampling method was adopted at two regular sampling areas (Vassouras and Itaguaí, Rio de Janeiro, Brazil). The places sampled only once were selected based on the potential migration of Dydercus. Various transects were determined, with 99 places; these transects involved six morpho-climatic-phytogeographical domains: Atlantic Tropical, Cerrado, Caatinga, Amazonic Equatorial, Pantanal and "Planalto das Araucárias". The food cycle of Dysdercus at Vassouras is based on the exploitation of reproductive structures (flowerand fruit) of some... |

| Ectoedemia (Etainia) obtusa (Puplesis & Diškus), described from Turkmenistan, is for the first time recorded from Europe: Spain, France, Italy and Croatia. It has been reared from cocoons, partly found on trunks of Fraxinus ornus L., which is considered to be its probable host. The female is described here for the first time and the male redescribed and illustrated. A checklist and key of the seven Western Palaearctic species of the subgenus are provided. Ectoedemia (Etainia) obtusa (Puplesis & Diškus), beschrieben aus Turkmenistan, wird zum erstenmal aus Europa gemeldet, namentlich aus Spanien, Frankreich, Italien und Kroatien. Die Art wurde aus Puppen gezüchtet, die teilweise auf Stämmen von Fraxinus ornus L. gefunden wurden; diese Pflanze... |

| O pulgão Schizaphis graminum (Rondani) (Hemiptera: Aphididae) é uma das principais pragas do sorgo. O objetivo deste trabalho foi determinar o efeito da alimentação deste inseto com genótipos de sorgo resistentes e suscetíveis no desenvolvimento do predador Cycloneda sanguinea (Linnaeus) (Coleoptera: Coccinellidae). O pulgão foi criado em folhas dos genótipos de sorgo GR 11111 e TX 430 x GR 111, resistentes, GB 3B, de resistência moderada e BR 007B, suscetível ao hemíptero. As larvas de C. sanguinea foram alimentadas diariamente, ad libitum, com ninfas e adultos de S. graminum. A duração das fases de desenvolvimento e a sobrevivência de C. sanguinea não foram influenciadas pelo genótipo. Apenas a duração do quarto ínstar, da fase larval e do período de... |

| Abstract This study examined temporal variation in the abundance of immature stages of Elbella luteizona (Hesperiidae) and describes the morphology and behavior of the larvae on their host plants, Byrsonima coccolobifolia and Myrsine guianensis. Five hundred sixty-eight 10 m diameter plots were searched for caterpillars in the Brazilian Cerrado over a period of one year. We inspected 5968 host plants, and found 31 eggs and 262 larvae on 244 plants. Similar numbers of immatures were found in both species of host plants. The abundance of immature stages varied monthly and was significantly higher in the dry season on both host plants, which may be due to the low density of natural enemies during that time. E. luteizona is univoltine, and larvae present... |

| Eloria subapicalis (Walker, 1855) is a rare species (61 individuals in four years of samplings) of Noctuidae (Lymantriinae) with a specific diet consisting of leaves of Erythroxylum P. Browne (Erytroxylaceae) species in Brasilia's cerrado. Generally, the rarity of a caterpillar species may have many explanations such as a generalist diet, being restricted to a host plant that is scarce in the area, or occurring in a limited geographical area. However, all the above explanations do not apply to E. subapicalis because it shows specificity of diet, uses a common host plant in the cerrado areas, and has a large geographical distribution. |

| Host plant feeding preference is important basic information for the development of insect management strategies. Multiple-choice feeding preference assays were conducted in the laboratory for the chrysomelid beetle, Microtheca punctigera (Achard). Feeding was assessed 72 h after onset of experiments. With one larva per Petri dish, food items comprised watercress, Nasturtium officinale L., arugula, Eruca sativa L., mustard, Brassica juncea Cosson, Chinese cabbage, B. pekinensis (Lour.) Rupr. and wild radish (Raphanus raphanistrum L.). Feeding ranking preferences were Chinese cabbage, mustard, wild radish, arugula and watercress (7.97, 1.85, 0.98, 0.36 and 0.11 mm², respectively). Feeding on Chinese cabbage was 4.31 times more intense than on mustard. The... |

| Heteropsylla caldwelli Burckhardt (Psyllidae, Ciriacreminae) is reported for the first time from Brazil(States of Minas Gerais, Paraná, Rio Grande do Sul) from Enterolobium contortisiliquum (Vell.) Morong.The earpod tree, from Albizia edwallii (Hoehne) Barneby and J.W. Grimes and Senegalia polyphylla (DC.)Britton (Fabaceae, Mimosoideae), all previously unknown hosts. The population dynamics of the psyllidwere investigated in a seven-year-old plantation of E. contortisiliquum in an abandoned open-pit coal minein Candiota, Rio Grande do Sul during two years. The population showed peaks in spring and summer,correlating directly with the mean air temperature and the population size of microhymenoptera. |

| Phyllophaga cuyabana is a univoltine species and its development occurs completely underground. Its control by conventional methods, such as chemical and biological insecticides, is difficult, so it is important to understand its dispersion, reproduction, and population behavior in order to determine best pest management strategies. The objective of this work was to study the behavior of adults of P. cuyabana. This study was carried out in the laboratory, greenhouse and field sites in Paraná State, Brazil (24º25' S and 52º48' W), during four seasons. The results obtained demonstrate that: a) P. cuyabana adults have a synchronized short-flight period when mating and reproduction occurs; b) adults tend to aggregate in specific sites for mating; c) the... |
