Bionomic data and larval density of Scarabaeidae (Pleurosticti) in sugarcane in the central region of Mato Grosso do Sul, Brazil

Bionomic data and larval density of Scarabaeidae (Pleurosticti) in sugarcane in the central region of Mato Grosso do Sul, Brazil. Phytophagous larvae of Scarabaeidae cause damage to diverse crops. Information on these pests is scarce; therefore, the objective of this study was to determine biological aspects and larval density of species occurring in an area of sugarcane. The studies were developed in Sidrolândia from April 2009 to March 2010. Scarab beetle larvae were collected in sugarcane roots every fifteen days, taken to the laboratory and reared to obtain the adults and determine biological parameters. A total of 2,656 larvae were collected, being 162 Liogenys fuscus, 120 Cyclocephala verticalis, 37 Cyclocephala forsteri, and 2337 Anomonyx sp. In January, 53.65 larvae m-2 were obtained, and the most abundant species was Anomonyx sp, representing 87.99% of the total larvae collected. From November to March, the greatest densities of Anomonyx were observed in the field. The adults of this species occurred from May to September, and egg laying from September to November. Eggs measured 1.1 x 1.7 mm, and incubation period last 15.4 days. First instar larvae were observed mainly in October; second instar larvae from November to April; and third instar from January to July. Pupae were observed from May to August. The most abundant scarab beetle, Anomonyx sp. in roots of sugarcane presents one generation per year in Sidrolândia, MS.<br>Dados bionômicos e densidade larval de Scarabaeidae (Pleurosticti) em cultura de cana-de-açúcar na região central de Mato Grosso do Sul, Brasil. Larvas fitófagas de Scarabaeidae causam danos em diversas culturas. Entretanto as informações sobre essas pragas são bastante escassas. Assim, o objetivo deste estudo foi determinar aspectos morfológicos, biológicos e densidade larval de escarabeídeos em área de cana-de-açúcar. Os estudos foram desenvolvidos em Sidrolândia, MS, de abril de 2009 a março de 2010. As larvas presentes nas raízes de cana-de-açúcar foram coletadas quinzenalmente, levadas para o laboratório e criadas até a obtenção de adultos e avaliação de parâmetros biológicos. Foram coletadas 2.656 larvas, sendo 162 de Liogenys fuscus, 120 de Cyclocephala verticalis, 37 de Cyclocephala forsteri e 2337 Anomonyx sp. Em janeiro, foram registradas 53,65 larvas m-2, sendo Anomonyx sp. a espécie mais abundante, representando 87,99% do total. De novembro a março, foram observadas as maiores densidades de Anomonyx no campo. Os adultos foram observados de maio a setembro. A postura ocorreu de setembro a novembro. Os ovos mediram 1,1x 1,7 mm, com período de incubação de 15,4 dias. As larvas de primeiro ínstar foram observadas em outubro, as de segundo ínstar de novembro a abril e as de terceiro de janeiro a julho. As pupas ocorreram de maio a agosto. A espécie de Scarabaeidae mais abundante na cana-de-açúcar é Anomonyx sp., que apresenta uma geração por ano

Seasonal interference and from milk production volume in SPC and SCC results

Dairy activity, as well as the search for excellence in the quality of milk and its derivatives, are constantly evolving in Brazil. The quality of the final product is related to each of the production stages, from nutrition, sanitary management of the herd, milking management, post-milking milk refrigeration time and temperature, cleaning and sanitization of machines and utensils, to transport, storage, and time elapsed between all these steps until processing. Thus, two raw milk samples were collected per month for quality analysis, for twelve months (October/2018 to September/2019), from the refrigeration tank of dairy farms in seven regions of the state of Minas Gerais. The interaction between the variables was verified: volume of production and period of drought and rainy season, with the quality parameters: Standard Plate Count (SPC) and Somatic Cell Count (SCC). It was observed that there was an interaction between the variables production volume and time of the year only in the SPC results, in which in the rainy season and the properties with a smaller volume of milk production, we observed that the averages highest was obtained. For the SCC variable, no interaction (p0.05) was observed between the variables studied and the SCC averages, however, the highest results were observed in the rainy season

An analytical cross-sectional study was carried out via the histopathological analysis of 70 samples of liver patients, collected between 2000 and 2017, with confirmed laboratory diagnoses, who died due to infection and complications due to yellow fever (YF), dengue fever (DF), and chikungunya fever (CF), to characterise, quantify, and compare the patterns of histopathological alterations in the liver between the samples. Of the histopathological findings in the human liver samples, there was a significant difference between the control and infection groups, with a predominance of alterations in the midzonal area of the three cases analysed. Hepatic involvement in cases of YF showed a greater intensity of histopathological changes. Among the alterations evaluated, cell swelling, microvesicular steatosis, and apoptosis were classified according to the degree of tissue damage from severe to very severe. Pathological abnormalities associated with YFV, DENV, and CHIKV infections showed a predominance of changes in the midzonal area. We also noted that, among the arboviruses studied, liver involvement in cases of YFV infection was more intense

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
