Resumo -O objetivo deste trabalho foi avaliar os parâmetros biológicos e determinar a tabela de vida de fertilidade de Neopamera bilobata (Hemiptera: Rhyparochromidae) em morangueiro. O experimento foi realizado no Laboratório de Entomologia da Embrapa Uva e Vinho, em Bento Gonçalves, RS, em câmara climatizada (a 23±1°C, 70±10% UR e fotófase de 12 horas). Utilizaram-se folíolos, flores, frutos verdes e maduros de morangueiro 'Aromas' como alimento para os percevejos. O desenvolvimento das fases imaturas e os parâmetros biológicos dos adultos foram monitorados diariamente. O percevejo N. bilobata não completou o ciclo biológico em folíolos e flores de morangueiro. Em frutos maduros e verdes, o tempo de desenvolvimento da ninfa ao adulto foi de 32,8±9,12 e 36,7±6,80 dias, com viabilidade de 27,3 e 51%, respectivamente. O período de oviposição foi de 34,7±21,2 dias, com 319,1±262,7 ovos em frutos maduros, e de 43,9±18,3 dias, com 318,2±144,7 ovos em frutos verdes. Neopamera bilobata completa seu ciclo biológico na cultura do morangueiro. Frutos verdes de morangueiro são mais adequados ao desenvolvimento deste inseto do que frutos maduros.Termos para indexação: Neopamera bilobata, Fragaria x ananassa, "catfacing", deformação dos frutos, pequenas frutas, percevejo. Biological parameters and fertility life table of Neopamera bilobata (Hemiptera: Rhyparochromidae) on strawberryAbstract -The objective of this work was to evaluate the biological parameters and to determinate the fertility life table of Neopamera bilobata (Hemiptera: Rhyparochromidae) on strawberry. The experiment was carried out in the Laboratory of Entomology of Embrapa Uva e Vinho, in Bento Gonçalves, RS, Brazil, in a climatic chamber (at 23±1°C, 70±10% RH, and 12-hour photoperiod). Leaflets, flowers, and green and ripe fruit of 'Aromas' strawberry were used to feed the insects. The development of immature stages and the biological parameters of adults were daily monitored. The bug N. bilobata did not complete the life cycle on strawberry leaflets and flowers. On mature and green fruit, the nymph-adult development time was of 32.8±9.12 and 36.7±6.80 days, with viability of 27.3 and 51%, respectively. The oviposition period was of 34.7±21.2 days, with 319.1±262.7 eggs on ripe fruit, and of 43.9±18.3 days, with 318.2±144.7 eggs on green fruit. Neopamera bilobata completes its biological cycle on strawberry crop. Green fruit of strawberry are more suitable for this insect development than ripe ones.

“…Since L. riparia is regarded as a nocturnal species (Walker and Newman, 1976;Buschman et al, 1977;Price and Shepard, 1978;Strandberg, 1981b), earwigs will rarely be in direct contact with sprayed insecticides in the field. Therefore, the insecticides are expected to exhibit even lower harmful influences in the field than in the laboratory, and other insecticides can be selected as virtually compatible with the conservation of L. riparia.…”

“…Labidura riparia Pallas (Dermaptera: Labiduridae) is regarded as an important mortality factor of insect pests in various crop fields (Ammar and Farrag, 1974;Buschman et al, 1977;Strandberg, 1981a, b;Godfrey et al, 1989;Pair and Gross, 1989;Kharboutli and Mack, 1993) and sometimes becomes a dominant species among predatory insects Mack, 1991, 1993;Kohno et al, unpublished); therefore L. riparia should be conserved in agricultural ecosystems as a promising natural mortality factor against insect pests.…”

Using a direct spraying test in the laboratory, nine Bt insecticides, a Beauveria bassiana insecticide, two IGRs (methoxyfenozide and chromafenozide), and a synthetic insecticide (pyridalyl) were determined to be harmless and a synthetic insecticide (dinotefuran) was determined to be slightly harmful to second instar Labidura riparia nymphs, which are regarded as an important natural mortality factor against insect pests in various crop fields. The use of these insecticides should be recommended in IPM programs to control cabbage insect pests, since they are regarded as being compatible with the conservation of L. riparia in the field.

“…According to the results of this Other study showed that Dermaptera of genus Dorus are efficient herbivorous predators in corn monoculture (see Cruz 1991). Additionally, Buschman et al (1977) Some studies have shown that the result of ant-plant interaction is dependent of the species of predatory ants involved interaction (Byk & Del-Claro, 2010;Calabuig et al, 2015) and of the strategies of herbivorous against predation (Bächtold & Alves-Silva, 2013;Carita et al, 2006;Styrsky & Eubanks, 2010). Nevertheless, little is known about the behavior between pairs (predator-prey) determining plant protection.…”

Alternative methods to reduce the chemical control in monoculture have been widely assessed in order to diminish the pesticide use. Thus, the efficiency of predator arthropods who work as population controllers in many agro-ecosystems has been tested. The current study aim to verify if the presence of ants interfere in the amount of arthropod herbivores and predators on corn plants, Zea mays L. (Poaceae). A total of 100 plants were assessed, out of them, 50 were isolated from ants and the other 50 were not. There were 25 taxa of arthropods on corn plants, in which 14 were herbivorous and 11 predators. The ants' free access to the plants negatively influenced the Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae) amount, which is an important herbivorous plague in corn monoculture. It was also observed the greater amount of Doru sp.1 (Dermaptera: Forficulidae) on plants containing ants. Considering the assessed plants, the presence of ants did not influenced the abundance of other arthropods. These results suggest that the ant-plant-herbivore interactions in corn monoculture is a complex system, and the presence of predatory ants in plants not always influence the presence of other arthropods. ResumoMétodos alternativos ao controle químico de pragas em monoculturas têm sido amplamente avaliados com o intuito de diminuir o uso de agrotóxicos. Neste sentido, a eficiência de artrópodes predadores que agem como controladores de populações nos mais diversos agroecossistemas vem sendo testada. Este estudo objetivou verificar se a presença de formigas interfere na abundância de artrópodes herbívoros e predadores sobre plantas de milho, Zea mays L. (Poaceae). Foram avaliadas 100 plantas, 50 isoladas de formigas e as outras 50 não isoladas. Foram observados 25 taxa de artrópodes sob plantas de milho sendo 14 de herbívoros e 11 de predadores. O livre acesso das formigas às plantas influenciou negativamente a abundância de Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae), um importante herbívoro praga da monocultura de milho. Nas plantas com formigas foi também observada maior abundância de Doru sp.1 (Dermaptera: Forficulidae), um importante inimigo natural de pragas em agroecossistemas. A abundância dos demais artrópodes não foi influenciada pela presença das formigas nas plantas avaliadas. Esses resultados sugerem que a interação formiga-planta-herbívoro em monocultura de milho é um sistema complexo, e que a presença de formigas predadoras sob plantas nem sempre interfere na presença de outros artrópodes.
