| Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) was exposed to gammacyhalothrin to study the stimulatory effect of low concentrations of this pyrethroid. The doses studied were 23.4375, 11.7188, 5.8594, 2.9297, 1.4648, 0.7324 mg.litre-1 and water, as control. The third, fourth, and fifth instars of P. nigrispinus were shorter with all the doses of this insecticide. The survival and longevity of this predator was highest with the lowest doses. The oviposition period of P. nigrispinus decreased as the doses increased. The lowest pre-and postoviposition periods were found with 11.7188 mg.litre-1 of gammacyhalothrin. The dose 0.7324 mg.litre-1 increased the clutch interval. The egg viability was similar between the treatments. The number of eggs per... |

| Com o objetivo de comparar os danos causados pelo percevejo Nezara viridula (L.) na cultivar de soja (Glycine max Merrill), 'Bragg', de semente pequena, foram conduzidos dois experimentos em casa-de-vegetacao e um experimento em campo, no Centro Nacional de Pesquisa de Soja, da EMBRAPA, em Londrina, PR. Alem do dano, observou-se a localizacao das sementes danificadas em diferentes alturas da planta, e a capacidade de dano do percevejo. Os resultados indicaram menor peso e percentagem de sementes danificadas nas linhagens BR 79-15807 e BR 79-15197, do que na 'Bragg'. Observou-se que os percevejos se alimentaram principalmente nos tercos superior e medio da planta. O numero de sementes picadas/percevejo/dia foi de 3,7 na 'Bragg'e de 3,4 na BR 79-15807. Em... |

| Artificial diets prepared with wheat germ, soybean protein, dextrosol, potato starch, sucrose, cellulose, soybean or sunflower oil, and vitamin solution for rearing Nezara viridula (L.) and Euschistus heros (Fabricius) were tested under controlled temperature (25 ± 1°C), RH (60 ± 10%), and photophase (14h). Three diets were tested and compared with the natural diet privet [soybean and peanut seeds and privet Ligustrum lucidum Ait. fruit (Oleaceae)]. All three artificial diets allowed full development. The diet containing sunflower oil was the most suitable for N. viridula while E. heros developed better on a diet composed of soybean oil. Data indicated that the artificial diets were inferior to the natural diet. The artificial diets were more adequate for... |

| Laboratory studies were conducted to compare duration of feeding and superficial and in-depth damage to soybean (Glycine max) seeds by the Southern green stink bug, Nezara viridula (L.), the Neotropical brown stink bug, Euschistus heros (F.), the red-banded stink bug, Piezodorus guildinii (Westwood), and the green-belly stink bug, Dichelops melacanthus (Dallas). Results indicated that feeding time was significantly longer for N. viridula (≈ 133 min) compared to E. heros and D. melacanthus (≈ 70 min), but not different from P. guildinii (≈ 103 min). There was a positive correlation between feeding time and the resulting damage for E. heros, N. viridula and P. guildinii (R² > 0.80, P < 0.0001), but not for D. melacanthus (R² = 0.1011, P = 0.1493).... |

| Estudos comparativos entre Nezara viridula (L.) sadios e parasitados por Eutrichopodopsis nitens Blanchard em diferentes idades de desenvolvimento mostraram que o parasitismo afetou drasticamente a capacidade reprodutiva e a longevidade dos adultos quando este ocorreu na fase de ninfa ou em adultos recem formados. Nestes dois casos, nao se obteve producao de ovos, e a longevidade foi reduzida em 16,1 e 15,3 dias para machos e 30,9 e 177 dias para femeas, respectivamente. Quanto ao desempenho reprodutivo, o efeito de E. nitens foi menor quando parasitou percevejos mais velhos, causando uma reducao media de 58,6 % na fecundidade das femeas parasitadas no setimo dia de vida, enquanto que a fertilidade e o tamanho das massas de ovos nao foi afetada pelo... |

| Laboratory studies with 1st instar of southern green stink bug, Nezara viridula (L.) indicated that relative humidity (RH) greatly affected nymph emergence and survivorship up to the 2nd instar, reaching the maximum value (<FONT FACE=Symbol>»</FONT> 90%) with RH of > 80%. At 60% RH, 60% of the nymphs emerged and survived, while with 0% RH only <FONT FACE=Symbol>»</FONT> 15% of eggs hatched, and most nymphs died. Emerged nymphs from egg masses placed in plastic boxes with a gradient of humidity remained on egg shells for ca. one day. After this period, they dispersed and regrouped on top of shells 6.8 ± 0.67 times, until they abandoned the shells toward the source of humidity, avoiding the water-saturated areas. Duration taken for... |

| We studied the effect of environmental complexity and plant architecture on the abundance of the Edessa rufomarginata bugs in pastures and cerrado areas and its biology. We observed higher number of bugs on Caryocar brasiliense trees in the cerrado than pasture areas. Bugs were more abundant on leaves and branches rather than fruits. Caryocar brasiliense had greatest fruit production on pasture than in the cerrado areas. The abundance of bugs was correlated positively with aluminum, organic matter, and tree height, but negatively correlated by soil pH. Productivity of C. brasiliense were negatively correlated with aluminum, pH, and number of bugs, but positively correlated with phosphorus and calcium. The number of eggs per clutch was 14.3, their viability... |

| First records of Glyphepomis adroguensis (Hemiptera, Pentatomidae) and its parasitoid, Telenomus podisi (Hymenoptera, Platygastridae), on rice fields in Rio Grande do Sul, Brazil. Eggs, nymphs, and adults of Glyphepomis adroguensis Berg, 1891 (Hemiptera, Pentatomidae) were observed for the first time on rice fields (Oryza sativa L.) in Charqueadas (29º59'S, 51º31'W) and Eldorado do Sul (30º02'S, 51º23'W) of Rio Grande do Sul state, Brazil. Telenomus podisi Ashmead, 1893 (Hymenoptera, Platygastridae) was found in G. adroguensis eggs. |

| Results of field evaluations indicated that the neotropical pentatomid Dichelops melacanthus (Dallas) is associated with wheat, Triticum aestivum L. In the no-tillage cultivation system, adults and nymphs were mostly found on the soil, near the plant stems and underneath crop residues of the preceding summer crop, usually soybean, Glycine max (L.) Merrill, or corn, Zea mays L. Wheat grown under the conventional cultivation system showed minimal bug attack. D. melacanthus caused substantial damage to no-tillage wheat plants, particularly to seedlings. Bug attack reduces the number of seed heads of up to 34%. Seed yield was reduced in 31% due to the bugs' feeding, compared to plants free of damage. All developmental phases of the wheat plant were susceptible... |

| Estudos em laboratorio com adultos de Nezara viridula (L.) demonstraram que a sobrevivencia, a longevidade, a reproducao e o ganho de peso variaram em funcao da troca de alimento da fase ninfal para a fase adulta e do estresse nutricional na fase adulta. Em geral, a sobrevivencia e a longevidade dos adultos em vagem verde de soja [Glycine max (L.) Merrill] - VVS - e em semente madura de soja - SMS - foram superiores quando as ninfas alimentaram-se em VVS, em comparacao com adultos, cujas ninfas alientaram-se em vagem verde de feijao (Phaseolus vulgaris L.) - VVF. Adultos alimentados com haste + folha de soja (HFS) ou deixados em jejum, na presenca de agua, tiveram sua longevidade reduzida a metade. O desempenho reprodutivo foi reduzido quando VVF foi... |
