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.

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 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.

Method: A cross-sectional, descriptive, quantitative study was conducted to retrospectively analyze 54 medical records of neonates diagnosed with gastroschisis treated at the study hospital between January 2006 and January 2016. The analysis included all medical records of infants diagnosed with gastroschisis and born in the institution studied, as well as those who were transferred from other health institutions in the period examined. Medical records were searched through electronic consultation to the institution's Epidemiology Service, using the International Code of Diseases (ICD) 10 Q 793). Later, the files were accessed through the Medical Records and Statistics Service. Information was collected using a form containing the study variables. The data analysis was performed using SPSS software, version 21.0. The study complied with the ethical aspects of human research legislation. Results: The prevalence of gastroschisis was 0.11%, totaling 54 cases identified. Mean maternal age was 20.2 years; sex distribution was equal among newborns with the malformation; and 72.5% of cases had primary abdominal closure. Conclusion: The results for related causes and treatment, such as maternal age, drug use, and type of abdominal closure, were similar to findings from other studies on gastroschisis.

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...

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,...

One of the most peculiar and well-known species of Hemileucinae moths is Dirphia araucariae Jones, 1908 due to the larval monophagous feeding habits, which are restricted to Pinheiro-do-Paraná needles-Araucaria angustifolia (Bertol.) Kuntze, Araucariaceae. The Pinheiro-do-Paraná is the dominant tree species of the Araucaria Pine Forest, the typical phytophysiognomy of Southern Brazil and nearby areas in Argentina and Paraguay. The original geographical range of A. angustifolia has been estimated as nearly 200,000 km 2 , yet nowadays only 3% of this area remains due to logging and the development of agriculture (ENRIGHT & HILL 1995). As A. angustifolia has high quality wood, many efforts were undertaken to cultivate it, and also to preserve it, since it is considered a critically endangered species according to the IUCN red list (FARJON 2006). Larvae of D. araucariae are voracious, being capable of eating almost all leaves of an A. angustifolia tree during population outbreaks. Therefore, it is known that D. araucariae is capable of causing serious damages on native A. angustifolia forests, as well as reaching the economic damage level on plantation forests, as reported in several occasions (

Among the usual lipids found in the insect cuticle, α-tocopherol and α-tocopheryl acetate were also isolated from S. cosmioides. On the other hand, no vitamin E derivative was found in A. gemmatalis exuvia. This is the first report of vitamin E occurrence in the insect's cuticle.

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...

For this purpose, a new rearing method and artificial diet was employed and validated. The viability of the egg, larval, pupal and pre-pupal stages was 94.54, 97.33, 93.84 and 92.34%, respectively. The average duration of the egg, larval, pupal and pre-pupal stages was 4.14, 16.37, 1.69, and 9.34 days, respectively. During the larval stage, 80.85% of females and 93.99% of males passed through six and remaining through seven instars, with significant larval protandry. The larvae that developed through six and seven instars exhibited a mean growth rate of 1.58 and 1.48, respectively. Fifty five host plant species belonging to 29 families are listed. The female pupae were significantly larger, exhibiting protogyny. Both the rearin...

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 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.

As A. angustifolia has high quality wood, many efforts were undertaken to cultivate it, and also to preserve it, since it is considered a critically endangered species according to the IUCN red list (FARJON 2006). Larvae of D. araucariae are voracious, being capable of eating almost all leaves of an A. angustifolia tree during population outbreaks. Therefore, it is known that D. araucariae is capable of causing serious damages on native A. angustifolia forests, as well as reaching the economic damage level on plantation forests, as reported in several occasions (

Among the usual lipids found in the insect cuticle, α-tocopherol and α-tocopheryl acetate were also isolated from S. cosmioides. On the other hand, no vitamin E derivative was found in A. gemmatalis exuvia. This is the first report of vitamin E occurrence in the insect&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s cuticle.

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...

For this purpose, a new rearing method and artificial diet was employed and validated. The viability of the egg, larval, pupal and pre-pupal stages was 94.54, 97.33, 93.84 and 92.34%, respectively. The average duration of the egg, larval, pupal and pre-pupal stages was 4.14, 16.37, 1.69, and 9.34 days, respectively. During the larval stage, 80.85% of females and 93.99% of males passed through six and remaining through seven instars, with significant larval protandry. The larvae that developed through six and seven instars exhibited a mean growth rate of 1.58 and 1.48, respectively. Fifty five host plant species belonging to 29 families are listed. The female pupae were significantly larger, exhibiting protogyny. Both the rearin...

Método: trata-se de um estudo qualitativo, exploratório e descritivo, com 15 pais que tinham filhos de até dois anos de idade, em aleitamento materno, acompanhados em consulta de puericultura em Unidade Básica de Saúde. Foram excluídos pais com diagnóstico de doença mental, aqueles cujos filhos tinham contraindicação absoluta para o aleitamento materno ou que as mães conviviam com o vírus do HIV. O recorte temporal abrangido foi de março a julho de 2019. A coleta de dados ocorreu por meio de entrevista semiestruturada. Para a análise dos dados, utilizou-se a Técnica Análise de Conteúdo do tipo Temática. Resultados: Emergiram três categorias centrais: inserção paterna no processo da amamentação; dificuldades paternas na participação do processo de amamentação; questões de gênero e realização da paternidade. Considerações Finais: os pais reconhecem os benefícios do aleitament...
