ABSTRACT. Mendes C.deO.F., Silva A.C., Leal L.C.deS.R., Barbosa C.G & Bittencourt A.J. [Stomoxys calcitrans (Diptera:Muscidae) biology in byproducts of sugar cane industry.] Biologia de Stomoxys calcitrans (Diptera:Muscidae) em subprodutos da industria sucroalcoleira. Revista Brasileira de Medicina Veterinaria, 38(supl. 3):23-30, 2016. Departamento de Medicina e Cirurgia Veterinaria, Instituto de Veterinaria, Universidade Federal Rural do Rio de Janeiro, BR 465, Km 7, Campus Seropedica, RJ 23.890-000, Brasil. E-mail: camilamendes1009@gmail.com Stomoxys calcitrans fly is one of the dipterans of importance for livestock farming due to the considerable economic losses it determines worldwide. An aspect that favors the occurrence of this insect's outbreaks in Brazil is the generation of large quantities of by-products from the alcohol industry, such as vinasse, sugarcane straw, bagasse, filtercake and ashes. The present study aimed to evaluate the possible interference of vinasse and ashes on the immature stages of S. calcitrans, by comparing the biological parameters observed with or without the presence of these substrates. In Experiment I, three groups of 50 eggs were deposited in a diet composed of one kilogram of chopped cane and 250mL, 500mL and 1L of vinasse (groups 1, 2 and 3). In the control groups, distilled water was added to the chopped cane in the same proportions used in the groups treated with vinasse. In Experiment II, three groups of 50 larvae from eight to 10 days of emergence were deposited on a diet composed of cane, vinasse and ashes. The ashes were used in the proportion of 1, 2 and 3% (groups 1, 2 and 3) of sugar cane (100g) and vinasse was used in the proportion of 100mL for all groups and their respective controls. The control group contained only sugarcane and vinasse. Both experiments were kept in a climatized chamber (27 ± 1°C and 70-80% RH), and three replications were performed. After Experiment I, it was verified that the emergence of flies started more rapidly in Group 3 (17.33 days). The viability in Experiment I was lower in all groups in which vinasse was added in sugarcane, ranging from 20.66-34%, when compared to its controls (26.66-34.66%). In Experiment II, the onset of emergence of the flies was at seven days in all groups, lasting between 12.33 and 14 days on average, being lower for the groups that contained ashes in the diet. The viability in Experiment II was high in all groups with ashes (above 74%) and in the control, which presented greater viability (87%). When evaluating the emergence of males and females in Experiment I and II, it was observed that in all treated and control groups more females than males occurred. The evaluation of the data in the Experiment I allows the conclusion that vinasse can cause an early onset of the emergence of adults, but this emergency has a short duration. In Experiment II, ashes did not influence the onset of adult emergence, where the treated groups began their emergence at the same time as their control, while reducing the emergency period. Vinasse and ashes can interfere negatively in the development of immature stages of S. calcitrans, causing lower viability values for this insect.

Redistribuição de molibdênio aplicado via foliar em diferentes épocas na cultura da soja

Ciência e Agrotecnologia (2008)

Leila Maria de Freitas Moraes Regina Maria Quintão Lana Camila de Oliveira Ferreira Mendes e Paulo Cesar Doimo Mendes Anderson Monteiro

Objetivou-se com este experimento verificar a translocação de Mo aplicado em diferentes épocas do desenvolvimento da cultura da soja, pela determinação do teor em nódulos radiculares, folhas e grãos. O experimento consta de sete tratamentos instalados em blocos casualizados, e seis repetições. Os tratamentos foram constituídos pelas épocas de aplicação dos micronutrientes: 1) testemunha (sem aplicação); 2) Co e Mo via semente; 3) Co e Mo no estágio V4; 4) Co e Mo no estágio V6; 5) Co e Mo no estágio R1; 6) Co e Mo no estágio R3; e 7) Co e Mo via semente e no estágio R3. Nos tratamentos 2, 3, 4, 5 e 6, utilizaram-se as doses de 2,5 g ha-1 de Co e 80 g ha-1 de Mo, enquanto no tratamento 7forneceu 2,5 g ha-1 de Co e 20 g ha-1 de Mo nas sementes e no estádio R3 foi feita uma aplicação de 400 g ha-1 de Mo. A partir da aplicação, foram coletadas 20 plantas por parcela durante 9 semanas consecutivas, enquanto nos tratamentos 5 e 6, as coletas foram feitas por 8 e 7 semanas consecutivas, respectivamente. Avaliou-se a translocação de Mo das folhas para os nódulos e grãos, o teor de nitrogênio foliar e nos grãos, teor de proteína e de Mo nos grãos e a produtividade da soja. Os resultados demonstraram que o Mo aplicado via foliar transloca para os nódulos e para os grãos na fase de granação; as aplicações de Mo via foliar ou nas sementes não influenciaram o rendimento da cultura, os teores de nitrogênio e de proteína nos grãos; e a aplicação de 400 g ha-1 de Mo no estágio R3 aumentou os teores nos grãos.

Influence of weight loss on heart rate variability in dogs

Brazilian Journal of Veterinary Medicine/Revista Brasileira de Medicina Veterinária (2019)

Mário dos Santos Daniel Carvalho Hainfellner Nathália Marques de Oliveira Lemos Camila de Oliveira Ferreira Mendes Patrícia Malandrim

The autonomic nervous system (ANS) plays a role in the regulation of the cardiovascular system through sympathetic and parasympathetic modulations, which act in an associated way in the regulation of homeostasis. This regulation exercised by the ANS is determined by numerous factors including breathing, stress, temperature, blood pressure and physical activity. Cardiac nerve regulation is influenced by obesity, but the autonomic response present in this disorder has not yet been elucidated. It is known that a 10% increase in body fat is able to lead to a decrease in parasympathetic action and an increase in heart rate. Heart Rate Variability (HRV) allows the evaluation of autonomic heart modulation through the ventricular depolarization intervals to the electrocardiogram (ECG), and provides information on the relationship and contribution of the ANS to the neural influence of heart rate control. The objective of the present study was to evaluate the HRV by means of an electrocardiographic examination in obese dogs with Body Condition Score (BCS) 8/9 and 9/9, comparing with HRV of the same animals, after therapy with therapeutic ration in the period of 6 months, as well as the comparison with control group with lean animals. With the results obtained in the present study, it can be inferred that probably the imbalance in the autonomic activity due to obesity in dogs is not the same as in humans and that a greater understanding of this regulation in these animals is necessary, especially considering their vagotonia. The diet program based on low-calorie ration reached approximately 10% and 20% of weight reduction after two and six months, respectively. Obesity raises HRV by increasing parasympathetic activity in the autonomic regulation of the heart in dogs.

Ultrasound‐guided percutaneous choledochocentesis in a cat with cholelithiasis, choledocholithiasis and cholangitis due to Klebsiella pneumoniae

Veterinary Record Case Reports (2024)

L. V. Malliagros Camila de Oliveira Ferreira Mendes Ayla Cerqueira Aleluia dos Santos André Luís de Souza Teixeira Márcia Carolina Salomão Santos

Abstract A 13‐year‐old female cat was presented at our Veterinary Teaching Hospital with hyporexia and prostration. The animal underwent cholecystectomy 2 months previously due to partial biliary obstruction resulting from cholecystitis, multiple cholelithiasis, choledocholithiasis, dilation and tortuosity of the bile ducts. Due to the impossibility of puncturing the gall bladder and the persistence of dilation and tortuosity of the extra‐ and intrahepatic ducts identified by ultrasound, a dilated intrabiliary duct was punctured. The objective of the present study was to report the ultrasound‐guided percutaneous choledochocentesis technique, which, to our knowledge, is the first report of its performance in cats. The material was obtained for bile culture and antibiogram, which identified the bacterium Klebsiella pneumoniae , which was multiresistant to most antibiotics and uncommon in the biliary system. The technique was performed uneventfully, and was essential in the present report to assist in the presumptive diagnosis and treatment of cholangitis associated with cholelithiasis and choledocholithiasis.

Influence of obesity on the clinical improvement of tracheal and bronchial collapse in dogs: a case report

DOAJ (DOAJ: Directory of Open Access Journals) (2020)

Nathália Marques de Oliveira Lemos Mário Santos Filho Camila de Oliveira Ferreira Mendes Juliana Silva do Carmo Eveliny Oliveira Eleutério

Tracheal collapse is the most common progressive affection of the anterior pathways in small animals. The most common clinical symptom is a “goose honk” cough in cases of tracheal collapse and inspiratory discomfort in cases of cervical collapse. The diagnosis is based on the history, physical examination, and imaging tests, notably chest radiography and endoscopic examination. Treatment can be clinical or surgical depending on the degree of collapse. Obesity currently affects several domestic animals and predisposes them to respiratory disorders. The overlapping adipose tissue presses on the muscles of the trachea, aggravating the collapse and influencing the lung compliance and expansion. The present report describes the clinical improvement in an obese canine with tracheal and bronchial collapse after clinical management and therapeutic ration.

Virulência de Heterorhabditis bacteriophora cepa HP88 (Rhabditida: Heterorhabtidae) sobre larvas de Stomoxys calcitrans (Diptera: Muscidae) em dieta de torta de filtro

Brazilian Journal of Veterinary Medicine/Revista Brasileira de Medicina Veterinária (2016)

Américo de Castro Monteiro Sobrinho Camila de Oliveira Ferreira Mendes Luís Carlos de Souza Rodrigues Leal Avelino José Bittencourt

Economic losses caused by Stomoxys calcitrans are estimated at billions of dollars worldwide, with losses in Brazil being exacerbated by the large volume of byproducts of the sugarcane and alcohol industry, which serve as a development medium for the dipteran, especially the filter cake. In this context, entomopathogenic nematodes (EPN) appear as a biological control alternative. This work aimed to evaluate the action of the nematode Heterorhabditis bacteriophora - isolate HP88 on S. calcitrans larvae in the filter cake. In the laboratory, groups of five larvae were deposited in Petri dishes containing four grams of the filter cake. Concentrations of 25, 50, 100, 150 and 200 EPN /larvae of S. calcitrans, immersed in four milliliters of distilled water, were added to the Petri dishes. In the control group, there were no nematodes, only filter cake and distilled water. The dishes were sealed with PARAFILM®, and stored in a climatized chamber at 27±1°C and 70-80% relative humidity. The experiment was observed daily with six replicates. It was verified that the mortality of all the treated groups was superior to the one that occurred in the control group (6.6%). The mortality rate in the presence of 200 EPN/larvae was 83.3%; higher than that caused by 150 EPN/larvae (76.6%), although they did not differ statistically. Mortality due to other concentrations was 38.3%, 64%, and 63.3% in groups 25, 50 and 100EPN/larvae, respectively. When the control and 25 EPN/larvae group results were compared, mean mortality was significantly different. The study concluded that entomopathogenic nematodes are efficient in the control of S. calcitrans larvae reared in medium containing filter cake.
