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.

“…It is difficult to investigate trends in a species which was too common to have been recorded in detail until the advent of modern systematic surveys, but Edwin Lees, one of the most perceptive 19th century observers, noticed that in Worcestershire it tended to spring up in the footsteps of workmen in sites from which it was previously absent, and in this area it was so closely associated with human activity that he thought that it was probably alien (Preston 2003).

Biological Flora of the British Isles: Urtica dioica L.

Summary1. This account presents information on all aspects of the biology of Urtica dioica that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of the Biological Flora of the British Isles: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral and seed characters, herbivores and disease, history and conservation. 2. Urtica dioica is a tall, usually dioecious, rhizomatous, perennial herb with numerous stinging hairs, probably native in fens and semi-natural ancient woodlands, but widely naturalized in a range of habitats and abundant throughout the British Isles. British material is mainly ssp. dioica which also extends throughout Europe, and locally ssp. galeopsifolia (without stinging hairs) which is also found in western, central and eastern Europe. 3. Urtica dioica is a moderately shade-tolerant species, which occurs on most moist or damp, weakly acid or weakly basic, richly fertile soils. 4. A highly competitive ruderal species, Urtica dioica often forms monospecific stands which are not infrequently the product of a single individual that has spread by means of horizontal rhizomes. 5. Urtica dioica has frequently been described as a nitrophile, but there are many soils in which the supply of inorganic nitrogen is adequate for growth. However, there are other soils in which growth is checked with symptoms of severe phosphorus deficiency unless soluble phosphate is added to the soil. This is especially so in the long-established deciduous woodlands, and where there has been no addition of fertilizers to the soil. The growth responses of U. dioica to the availability, source and utilization of nitrogen and phosphorus have been examined experimentally in some detail. 6. Urtica dioica with its stems and leaves densely covered with stinging hairs, which release potential pain-inducing toxins when brushing contact is made with them, is rarely eaten by cattle and rabbits, but is palatable to some species of snail. It is the food plant of the larvae of a number of attractive butterflies and other phytophagous insects. 7. Male clones of U. dioica flower in advance of female clones. The pollen grains are extremely small. It is usually wind-pollinated, but occasionally insect-pollinated. 8. The low seed mass of U. dioica enables the production of vast numbers of seeds. Few of the seeds germinate in the period immediately following dispersal, and the species maintains a seed bank that changes little in size with season and is large in relation to annual seed production.Key-words: communities, conservation, ecophysiology, geographical and altitudinal distribution, germination, herbivory, nutrients, reproductive biology, soils Urticaceae, Urtica dioica L. (stinging nettle, common nettle) is a perennial herb with an extensive sympodial system of rhizomes and stolons, rooting at the nodes and giving rise in spring to aerial shoots up to 1.5-2 m or (rarely) 3...

Nysius natalensis Evans (Hemiptera: Orsillidae) is a pest of sunflower in South Africa. Adults invade sunflower fields from their weedy hosts which occur inside crop fields and on surrounding headlands. The host plant suitability for survival and reproduction as well as the effect of within‐generation host switching was studied on different wild host plants and sunflower. Life history parameters used to assess host plant suitability were F1 adult survival, pre‐oviposition period, fecundity, and longevity. Nymphs and adults were provided with stems and seeds of five host plants, viz., Amaranthus hybridus L. (Amaranthaceae), Portulaca oleracea L. (Portulacaceae), Chenopodium album L. (Chenopodiaceae), Conyza albida Spreng. (Asteraceae), and sunflower, Helianthus annuus L. (Asteraceae). Nymphs were reared on crushed seed of the five plant species. After completion of the nymphal stage, emerging adults of each host plant group were provided with seed of a different host plant species for food. Adults did not survive long on stems only and very few eggs were laid. Seeds of the host plant species were shown to be an essential source of nutrients for N. natalensis reproduction, whereas the vegetative plant parts were unsuitable. Nymphal food and host‐plant switching between the nymphal and adult stages significantly affected the pre‐oviposition period. Nymphal and adult food source also affected female longevity. The number of eggs laid was not influenced by nymphal food, but was influenced by adult food and the switch between nymphal and adult food. The comparative attractiveness of sunflower and wild host plants for oviposition was also investigated and showed that females preferred to lay eggs on wild host plants, compared with sunflower. These results may explain why N. natalensis will lay their eggs on sunflower after weeds in the vicinity are controlled, or senesce toward the end of the growing season.
