Objetivo: Conhecer os motivos associados à opção de mulheres pela gestação em idade avançada. Método: Trata-se de um estudo qualitativo, realizado com quinze mulheres com idade igual ou superior a 35 anos, primigestas que optaram pela gestação tardia e que estavam tentando engravidar a menos de um ano. Para a coleta de dados aplicou-se a entrevista semiestruturada e a análise dos dados seguiu a análise de conteúdo. Resultados: Da análise dos dados emergiram quatro categorias temáticas: obstáculos encontrados pelas mulheres na busca pela maternidade; influências na decisão pela gestação tardia; a perspectiva sociocultural da maternidade e as representações da maternidade tardia na percepção das mulheres. A maternidade em idade avançada converge com a redução da fertilidade a nível mundial, constituindo um problema de saúde pública. A busca por tratamentos de fertilização assistida e com ela a peregrinação em clínicas, elevados custos com tratamentos e o desgaste emocional são constan...

ABSTRACT Peridroma saucia (Hübner, [1808]) or ‘variegated cutworm’ is a cosmopolitan owlet moth pest resilient and abundant in agroecosystems. However, the morphology of their immatures is only briefly described, and information from distinct life stages is fragmentary. This study describes in detail all immature stages of the species based on a Neotropical population and compares it with populations from other continents and with other cutworm pests found in the Neotropical region. The eggs present useful characters to distinguish P. saucia from other noctuinae pests, such as the number of micropylar openings, and the number and location of aeropyles. The larvae also have unique characters, concentrated on the head capsule (mainly mandibles and spinneret), general color pattern and several aspects on the chaetotaxy. On the other hand, the pupae are remarkably similar to those of cutworms species, although the number of spines on cremaster is potentially a diagnosable character. In general, immature characters can therefore be useful to identify P. saucia regardless of the life stage. These results confirm the relevance of detailed morphological studies on immature of pest species that may be useful to identify and distinguish these individuals without the need of obtaining adults.

ABSTRACT Metarhizium rileyi is an entomopathogenic fungus of Lepidoptera and infects many noctuids, which are key pests of agricultural crops. In this literature review, we summarise the state of art and use of this potential biological pest control agent. Pathogen–host interactions include conidial adhesion, invasion process, and enzymatic activity. Environmental factors that impact the productivity associated with this fungus such as environment temperature, humidity, and availability of spores are discussed. Recent research has focused on enzymatic aspects related to pathogenicity, in which the cause is not fully elucidated yet. More than 60 known host species, mainly lepidopterans, are listed. Non-susceptible species, including predatory insects, are also presented. The difficulty of mass production and the formulation are the principal obstacles in use of M. rileyi. We summarise the challenges necessary to better utilise this agent in biocontrol and suggest novel research approaches, including the development of commercial and technically viable formulations.

The goal of the present study was to investigate biological aspects of Periga circumstans Walker, 1855 (Lepidoptera: Saturniidae: Hemileucinae) whose larvae were fed on leaves of khaki-plant (Diospyros khaki Linnaeus - Ebenaceae) and Mate-plant (Ilex paraguariensis Saint Hilaire - Aquifoliaceae) leaves. The biological parameters were obtained from specimens kept under controlled conditions: temperature of 25 ± 1 °C, relative humidity of 70 ± 10%, and photoperiod of 12 hours. For each developmental stage, morphological and ethological parameters are described. The larvae passed through six instars with a growth average rate of 1.4 for each instar. The host plants influenced significantly only the total duration of the larval phase, which was prolonged for larvae fed on khaki-plant leaves. Several aspects related to the morphology and the ethology of P. circumstans are similar to those described for Lonomia obliqua Walker, 1855.

The result of an inventory on the lepidopteran fauna associated with the South American Holly (erva-mate) is described. This inventory was based on a bibliographic review, the examination of specimens deposited in scientific collections from the state of Rio Grande do Sul, the systematic collection within commercial erva-mate farms located in Anta Gorda, RS, and on the occasional collections from native trees within the Região dos Vinhedos campus of the Universidade de Caxias do Sul. Every fifteen days between 20 August 2005 and 19 August 2006, 150 trees were visually inspected and all Lepidoptera were collected. A list of 75 lepidopteran taxa belonging to 16 families is presented, including 27 new occurrences for the erva-mate crop, of which 14 species represent new records for the state.

We studied the biology of Tiracola grandirena(Herrich-Schäffer, 1868) (Lepidoptera: Noctuidae: Hadeninae) at 25 ± 1 °C, 70 ± 10% RH and 14 hours of photo phase. Three experiments, using 150 larvae each, were conducted for the larval stage. In the first, used to assess the duration and survival of all stages, insects were reared individually and fed an artificial diet (Grenee). In the second, individuals were also reared separately, but were fed leaves of 10 plants from different families. In the third, the larvae were not individualised, the food plants were rotated such as to provide three plant species every 48 hours. In the first experiment, the viability of the eggs, larvae, pupae and prepupae was 91.9, 94.7, 32.49 and 43.5%, respectively. The average duration of the egg, larvae, prepupae, pupae and adult were 6.0, 25.3, 25.7, 21.4 and 12.7 days, respectively. The prolonged prepupal period indicates that T. grandirena can develop larval (prepupal) diapause. The results of the ex...

The representatives of the genus HylesiaHübner, [1820] are significant among the medically important Lepidoptera. Adult females use abdominal setae to wrap and protect the eggs that remain for months in nature. These setae, in contact with human skin, may cause allergic reactions including swelling, itching and local erythema, known as lepidopterism. The morphology of the abdominal scales and setae from the female H. oratex Dyar, 1913 is herein described and aspects related to their medical significance are discussed. Portions of each abdominal segment were examined through a scanning electron microscope. Two types of scales without medical importance, and two types of setae with medical importance, classified as "true setae" and "modified setae" were found. The true setae, which are slightly fusiform and have radially arranged lateral projections, are responsible for the allergic reactions caused by skin penetration. The modified setae, which are larger, curved,...

This study aimed to evaluate the biotic potential, life table parameters and fertility of Spodoptera albula (Walker, 1857) under controlled conditions (25 ± 1°C, 70 ± 10% RH and 14 hour photo phase). The longevity, pre, post and oviposition periods, fecundity and fertility of 13 couples were evaluated. The longevity of females (13.500 days) was significantly higher than those of males (11.154 days). The mean durations of the pre, post and oviposition periods were 2.615, 1.769 and 9.385 days, respectively. The mean fecundity was 1.417.69 eggs and mean fertility was 1.340.401 larvae, per female. On average, females copulated 1, 231 times. A strong positive correlation was observed between the number of copulations and fecundity (r = 0.847, p <0.001), as well as a strong negative correlation between the number of copulations and the duration of the pre-oviposition period (r = -0.762, p = 0.002), and longevity (r = -0.788, p = 0.001). The biotic potential of S. albula was estimated a...
