25. Euschistus heros mass rearing technique for the multiplication of Telenomus podisi.
The objective of this work was to improve the mass rearing technique of Euschistus heros in laboratory. Nymphs and adults were reared at densities 100, 200, 300 and 400 eggs per Petri dish (9 cm diameter), and at 50, 100, 150 and 200 couples per rearing cages (900 mL), respectively. Survival rate of immature stages and survivorship and reproduction of adults

26. Performance consequences of food mixing in two passion vine leaf-footed bugs, Holymenia clavigera Herbst, 1784 and Anisoscelis foliacea marginella Dallas, 1852 (Hemiptera : Coreidae) / Conseqüências da dieta mista na performance de dois coreídeos do maracujá, Holymenia clavigera Herbst, 1784 and Anisoscelis foliacea marginella Dallas, 1852 (Hemiptera : Coreidae)
Holymenia clavigera (Herbst) e Anisoscelis foliacea marginella (Dallas) (Hemiptera: Coreidae: Anisoscelini) ocorrem no sul do Brasil e são hóspedes de diversas espécies de Passifloraceae. Observações preliminares indicam uma alta coexistência destas espécies em termos de uso da planta hospedeira; em adição, ovos e ninfas são extremamente semelhante

27. Residual effect of a micro-encapsulated formulation of organophosphates and piriproxifen on the mortality of deltamethrin resistant Triatoma infestans populations in rural houses of the Bolivian Chaco region
The Bolivian Chaco is part of the endemic region of Chagas disease and an area where pyrethroid resistant Triatoma infestans (Hemiptera: Reduviidae) populations has been reported. The World Health Organization identified these resistant populations as an important focus for research. The objective of this study was to evaluate the residual effect of a micro-

28. Toxicidad de spiromesifen en los estados biológicos de Bactericera cockerelli (Sulc) (Hemiptera: Triozidae)
Spiromesifen is an insecticide that inhibits the synthesis of lipids and, in Mexico, its use against the Tomato-Potato Psyllid, Bactericera cockerelli (Sulc), on chili pepper (Capsicum annum), tomato (Lycopersicon sculentum) and potato (Solanum tuberosum) began in 2005; however more information is needed to understand its toxicity on this insect pest.

29. Aptitud biológica de poblaciones de Bemisia tabaci (Gennadius) Biotipo B (Hemiptera: Aleyrodidae) con diferente susceptibilidad al insecticida thiametoxam
In two field-collected populations of de Bemisia tabaci (Gennadius) B biotype previously selected with the neonicotinoid insecticide thiamethoxam (NEO-R, NEO-N), and a population susceptible to insecticides (SUSC), the level of response to the insecticide thiametoxam, as well as the life and fertility tables were determined. At LC95, the NEO-R population sho

30. Susceptibility of Triatoma brasiliensis from state of Ceará, Northeastern Brazil, to the pyrethroid deltamethrin
After controlling Triatoma infestans in Brazil, other species of triatomine that were considered minor in the transmission of Chagas disease became important. The persistence of Triatoma brasiliensis in Northeastern Brazil, associated with reinfection of domestic environments recently sprayed with pyrethroids, may be a signal of susceptibility alteration of

31. Transmisión del tomato Venezuela virus por Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), en Maracaibo, Venezuela
The biological transmission of Tomato Venezuela virus (ToVEV) by biotype B of the whitefly species Bemisia tabaci (Gennadius) increased (21.7-95.0%), and the time for symptom expression decreased (16-12.6 days) as the number of viruliferous whiteflies allowed access for inoculation to susceptible tomato plants increased from 1 to 20 adults/plant. When acquir

32. Descrição dos estágios imaturos e biologia de Chinavia pengue (Rolston) (Hemiptera, Pentatomidae)
Descrição dos estágios imaturos e biologia de Chinavia pengue (Rolston) (Hemiptera, Pentatomidae). Adultos de Chinavia pengue (Rolston, 1983) foram coletados em Garopaba, SC, e criados em laboratório sob condições controladas (24 ± 1°C; UR 70 ± 10%; 12hL:12hE). Como alimento, adultos e ninfas receberam vagens verdes de feijão (Phaseolus vulgaris L.

33. A new species of Crypticerya Cockerell (Hemiptera: Monophlebidae) from Colombia, with a key to species of the tribe iceryini found in South America
The adult female and first-instar nymph of a new species of iceryine scale insect, Crypticerya multicicatrices Kondo & Unruh sp. n., are described and illustrated. The new scale insect is polyphagous and was collected on 13 plant species distributed in seven botanical families, including fruit trees of economic importance such as mango and soursop. A taxonom

34. Imunobiologia das infestações de bovinos pelo carrapato Rhipicephalus (Boophilus) microplus: estudo dos correlatos imunes de resistência e de susceptibilidade / The immunobiology of infestations with the cattle tick Rhipiceplahus (Boophilus) microplus: comparative immunologic and molecular studies of the tick-host interface in susceptible and resistant bovine hosts.
The skin of vertebrates is the largest for over 15,000 species of hematophagous arthropods. Among them are ticks, which are long-term feeders and interact with host defenses for days to weeks. Little is known about specialized strategies for eliminating ectoparasites, but ticks can induce immune responses in host. Bovines present variable and heritable level

35. Taxonomy of Tricorythopsis Traver and Tricorythodes Ulmer (Ephemeroptera: Leptohyphidae) and advancements in the molecular studies of Ephemeroptera / Taxonomia de Tricorythopsis Traver e Tricorythodes Ulmer (Ephemeroptera: Leptohyphidae) e avanços nos estudos moleculares de Ephemeroptera
In order to contribute to the taxonomy of Tricorythodes Ulmer and Tricorythopsis Traver, new taxa were described and molecular techniques were used as complementary tools in the systematic of the Ephemeroptera. As a result of the work, five new species were described, three for genus Tricorythodes (T. rondoniensis, T. sallesi and T. caunapi) and two for Tric

36. Laboratory evaluation of the effects of triflumuron on the development of Rhodnius prolixus nymph
Studies were carried out to evaluate the efficacy of the growth regulator, triflumuron (TFM) (Starycide® sc 480 Bayer), for disrupting the development of Rhodnius prolixus fifth-instar nymph by oral, topical or continuous treatment. All treatments were able to induce high levels of mortality, delay development and molt inhibition. Oral treatment induced mol
