Biological and morphological aspects of Plectris aliena (Coleoptera: Melolonthidae) in sugarcane in Brazil

Plectris aliena (Coleoptera, Melolonthidae) Chapin is a species already recorded causing serious damage to various cultures in North America and Australia. Although its occurrence has recently been reported in Brazil, information about its distribution, taxonomy, and biology is limited. Thus, this study aims to report this new occurrence of P. aliena in Deodápolis (Mato Grosso do Sul, Brazil), as well as to present bioecological and morphological aspects of this species. In this way, the seasonal distribution and the life cycle was studied in the years 2017 and 2018. The larvae were sampled through trenches made in the soil and reared in the laboratory. Adults were captured using “Luiz de Queiroz” light traps. Adults have body with dense white hairs, antennae with 10 antenomeres; they measure approximately 12 mm in length, and their antennal lamellae are larger for males than females. The larvae reach 30 mm in length in the third stage and pupae show about 19 mm in length. The life cycle of this species is univoltine. Due to the great diversity of Plectris and the scarce information available about this species in South America, this study will facilitate its identification in the field and indicate the best time for monitoring in sugarcane crop

Morphology of immature stages and mating behavior in Liogenys fusca (Blanchard) (Coleoptera, Melolonthidae, Melolonthinae)

AbstractLiogenys fusca is a rizophagous insect pest in various crops of economic importance in Brazil. Here we investigated the morphology of immature stages and mating behavior of this species. The redescription of the 3rd instar larvae of L. fusca in this work allows identification and registration of occurrence independently of adults, which occur sporadically in a certain period of the year. Male and female of L. fusca remained confined in the soil during the day and exited between 19:00 and 23:30h. The copulations occurred between 19:30 and 21:00h, and were characterized by a typical behavioral sequence. Copulation durations in L. fusca lasted on average 512.23s. Adults were observed feeding before the copulations on leaves and inflorescences of plant species belonging to the family Anacardiaceae, Myracrodruon urundeuva, Schinus terebinthifolius, Astronium fraxinifolium and Anacardium occidentale

Quantidade de alimento para porcas gestantes confinadas em grupo

In order to evaluate the reproductive performance of sows under different alimentar regimens, 48 Large White gilts were utilized. They were subjected to four different rations during three consecutive reproductive cicle. These rations consisted of 2; 1.8; 1.6 and 1.4 kg of food per day, during gestation and "ad libitum" during lactation. During the gestation period, the sows were kept confined in groups of six per pen and they received the feed through individual feeders. Piglets wore weaned with 35 days of age. Each increase of feed consumption in the gestation period resulted in a linear increase in the weight gain of the sows (P<0,001). The weight of sows during lactation decreased linearly (P<0,01) with the increased consumption of feed during gestation. Biggest litters were observed in the second and third reproductive cicle. Nevertheless, no differences were observed among treatments in regard to the number of alive and death born piglets. Litters from sows kept under 2 kg of feed per day showed more weighty litters at birth and at the weaning period than those kept under 1.6 kg of feed. Mortality rate was higher among piglets from the third reproductive cicle than that from the second and first ones. Nevertheless, mortality rate was similar among litters from all treatments.Com quarenta e oito marrãs Large White com peso médio de 126 kg iniciou-se experimento com objetivo de avaliar o seu desempenho reprodutivo quando submetidas aos regimes de 2; 1,8; 1,6 e 1,4 kg de alimento por dia durante a gestação, e à vontade durante a lactação. Durante a gestação, as porcas permaneceram confinadas em grupos de seis por baia e receberam ração em bretes individuais, uma vez ao dia. O desmame dos leitões foi realizado aos 35 dias de idade. A cada aumento do nível de consumo de alimento na gestação resultou um aumento linear (P<0,001) no ganho em peso da porca. O peso durante a lactação decresceu linearmente (P<0,01) com o aumento de consumo na gestação. As porcas produziram leitegadas maiores na segunda e terceira parição, mas o número de leitões nascidos vivos ou mortos não foi diferente entre os tratamentos. O nível de 2 kg/dia proporcionou leitegadas mais pesadas (P<0,05) ao nascer e ao desmame em relação ao nível de 1,6 kg/dia

PETIÇÃO INICIAL: UMA ANÁLISE À LUZ DE TEORIAS BAKHTINIANAS

A importância dos estudos desenvolvidos por Bakhtin (2010a, 2010b, 2016), Volóchinov (2018) e Medviédev (2012) se estende a diversos campos da atividade humana. Os conceitos de enunciado, gêneros discursivos, destinatário e ideologia podem ser trazidos ao âmbito das ciências jurídicas e contribuir para estudos que se debrucem sobre a arquitetônica dos gêneros discursivos produzidos por esse campo de atividade. Neste trabalho, apresentamos uma abordagem de estudo relacionando a petição inicial e os conceitos de sobredestinatário e ideologia, desenvolvidos por Bakhtin (2010a, 2010b, 2016), Volóchinov (2018) e Medviédev (2012), contrapondo-os à ideia de neutralidade discursiva. Nossas conclusões apontaram que a petição inicial, por ser um gênero discursivo na concepção bakhtiniana, tem um destinatário (podendo este ser um sobredestinatário) e que não é possível se falar em neutralidade do discurso jurídico, pois a suposta neutralidade é, em si, um produto ideológico do pensamento positivista. DOI: https://doi.org/10.47295/mren.v9i4.267

Presence of protozoans and helminths in quilombola children from Agreste region of Pernambuco, Northeast Brazil / Presença de protozoários e helmintos em crianças que residem em comunidades quilombolas, localizadas na cidade de Garanhuns, Pernambuco

The aim of this research was to verify the occurrence of intestinal parasites in children aged between two and twelve years in four quilombola communities located in the city of Garanhuns, Pernambuco. The investigation was carried out between August 2008 and July 2009. Five visits were made to the communities in order to analyze the environmental sanitation, personal hygiene and socio-economic conditions of the families. After that, fecal samples were collected from 115 children from the communities to perform the coproparasitological exams, using the method of Hoffman, Pons &amp; Janer to search for larvae or eggs of helminths and protozoan cysts. From this, a general prevalence of 51.30% of enteroparasitosis was evidenced in the samples collected, identifying six species of protozoa and four of helminths. Thus, it was concluded that there is a need to monitor the health conditions of this population and the continuous search for sanitary improvements, in the offer of antiparasitic treatment and in health education

Rubinstein – Taybi in Syndrome a Peruvian patient with mild mental retardation: A case report / Síndrome de Rubinstein - Taybi em um paciente Peruano com leve retardo mental: Um relato de caso

Rubisntein-Taybi syndrome is of genetic origin, caused by a mutation in the CREBBP gene, which undergoes classic phenotypic changes and changes in neuropsychomotor development. In this sense, this article aims to report the case of a Peruvian patient with the clinical and genotypic diagnosis of the disease. During the prenatal period, the fetus did not have alterations that would suggest the syndrome, but at birth, it had a hemangioma, but without clinical repercussion. In the first three months of life, its development was normal, but from the fourth month on, delays were noticed. At 6 months of age, he was not holding his head, so the parents looked for a geneticist who first made the clinical diagnosis and then requested the karyotype, which confirmed the diagnosis. With this, he already started with multidisciplinary treatment and was still placed to study in regular schools in order to improve his development. Currently, at the age of 15, the patient is in treatment with a multidisciplinary approach and in a school to include children with some neurological weakness in the social environment, in order to avoid bullying from other colleagues. He presents phenotypic alterations characteristic of the syndrome, but the cognitive delay is mild when compared to other adolescents with the same pathology. Therefore, this work shows the need for diagnosis and a multidisciplinary approach in treatment. Even so, more studies are needed to learn more about this syndrome and thus provide a better safeguard of the lives of the patients, as occurred in the case of this patient

Rett Syndrome in a Peruvian patient: A case report / Síndrome de Rett em um paciente peruano: Um relato de caso

Rett syndrome is of genetic origin, caused by a mutation of dominant characteristic in the MeCP2 gene, which studies with psychomotor alterations in children. In this sense, this article aims to report the case of a Peruvian patient with the late diagnosis of the disease. The patient started the clinical characteristics of the disease at one year and two months, but the diagnosis, with a genetic study that identified the mutation, was only made at 3 years. During this period her diagnoses were: absence epilepsy and microcephaly. These misconceptions favored the accentuation of biopsychomotor delays. Currently, at the age of 4, the patient is being treated with a multidisciplinary approach, but as there are serious sequelae, there are delays in development and results take time to appear. Therefore, this work shows the difficulty of diagnosis, the need for a multidisciplinary approach in treatment and that there is a need for more studies to learn more about this syndrome and thus be able to provide a better safeguard of the lives of the patients
