The damage caused by the diamondback moth is a limiting factor in the production of brassicaceous plants worldwide and biological control by an egg parasitoid may be an effective way to control this pest. Thus, understanding oviposition preferences of pests and parasitoids in crop plants can be a key factor in optimizing biological control programs. The present study was aimed at determining the oviposition preference of Plutella xylostella and Trichogramma pretiosum in collard greens. Bioassays consisted of collard plants in cages and P. xylostella adults released inside to lay eggs on the leaves. After 24 hours, the adults were removed and T. pretiosum females released. In another experiment, cardboard strips containing P. xylostella eggs were offered to T. pretiosum released in cages with a collard greens plant inside and replaced every 2 hours for 24 hours. The results showed that P. xylostella has a preference for laying eggs on the leaves of the middle region of the plant, on the upper part of the adaxial surface. For T. pretiosum , no preference was observed, but mean parasitism rates were highest on the upper region of the adaxial surface, where most of the eggs were found. In the second experiment, the highest mean parasitism rates by T. pretiosum were observed at temperatures ranging from 25.9 to 37.4 °C and relative humidity between 42 and 78% in the photophase. No parasitism occurred in scotophase, indicating that field releases should be performed preferably in the early hours of the morning.

Background: The indiscriminate use of drugs is an issue in Veterinary Medicine, as it has serious consequences for the animals. Many drugs are myelotoxic and cause a decrease in the production of blood cells, which may be irreversible in some cases. The present work reports a case of pancytopenia induced by the concomitant use of myelotoxic drugs (estrogen, metamizole and phenobarbital) in a dog and describes findings on myelotoxicity, hematological alterations and treatment success.Case: A 7-year-old Lhasa Apso bitch was referred to the Veterinary Hospital of Federal University of Paraná, Curitiba campus, with hematuria and a history of treatment with phenobarbital [2 mg/kg twice a day (bis in die, BID)], metamizole [25 mg/kg three times a day (ter in die, TID)], and use of estrogen hormone (estradiol cypionate). At physical examination, the animal was normohydrated and exhibited normal palpable lymph nodes, pale mucous membranes, galactorrhea, and a body temperature of 36°C. A complete blood count including reticulocyte count and a total plasma protein (TPP) exam were requested. The results revealed pancytopenia (18% hematocrit, 1,400 total leucocytes/µL, and 22,000 reticulocytes/µL). An abdominal ultrasound exam did not detect any relevant alterations. In view of the results obtained, medullary aplasia was suspected. A bone marrow aspiration was performed. A myelogram revealed a decrease in cellularity (erythrocytic and granulocytic hypoplasia), with presence of rare erythroid and granulocytic precursors. The diagnosis was medullary aplasia. The animal was treated, and the evolution of the hematological alterations was monitored. The treatment consisted of administration of erythropoietin (100UI/kg subcutaneously every 48 h), prednisone (2 mg/kg BID), Leucogen (3 mg/kg BID), interferon (0.2 IU/kg BID) and Eritrós Dog Tabs [1 tablet once a day (semel in die, SID)]. After five days of treatment, the patient’s clinical picture improved (30% hematocrit, 5,300 total leukocytes/µL, 84,000 platelets/µL, and 195,000 reticulocytes/µL), and the hematological alterations were resolved after 25 days of treatment (43% hematocrit, 5,100 total leukocytes/µL, and 333,000 platelets/µL). The bitch was discharged after 89 days of treatment.Discussion: The hematological alterations found in the patient were consistent with pancytopenia, and the myelogram allowed the establishment of a diagnosis of medullary aplasia. There are various causes of pancytopenia in dogs; in this case, it was caused by medications, as the drugs administered to the patient (estrogens, metamizole, and phenobarbital) are myelotoxic. Canine bone marrow is susceptible to suppression by estrogens, which can induce medullary aplasia even with a single dose. No reports on hematological alterations caused by dipyrone (metamizole) in dogs were found; however, in humans, development of aplastic anemia, agranulocytosis, nephrotoxicity, and allergic reactions have been attributed to the use of this drug. Phenobarbital can cause adverse reactions that lead to anemia, leukopenia, and thrombocytopenia. Evaluating the bone marrow of animals with pancytopenia is important because this procedure allows the establishment of a diagnosis that may prompt treatment while hematopoietic precursors are still present in the bone marrow. In this case, a treatment using hematopoietic stimulants was employed owing to the presence of erythrocytic and myelocytic precursors in the patient’s bone marrow. The treatment instituted was efficacious, as only five days of therapy already improved the hematological condition of the patient, who was discharged after 89 days of treatment.

The hyperplastic cystic endometrial - pyometra complex is characterized by a hormonal disorder, with progesterone as the protagonist, leading to the appearance of ovarian cysts and a sequence of changes in the endometrium, followed by bacterial colonization, with Escherichia and Staphylococus being among the main ones, being thus, the objective was to isolate them and evaluate their sensitivity to Gentrin® in three different concentrations (150mg, 200mg and 300mg), with Ceftriaxone as control. Ten female dogs were used for this research, with an average age of 7 years, after collecting the secretions of pyometra, Escherichia and Staphylococus were isolated from them for culture and antibiogram. They were isolated from E. coli in 60% of the samples and Staphylococus spp. in 40%, in the antibiogram tests both demonstrated 100% sensitivity to Gentrin® of 300mg, and in smaller percentages to 150mg and 200mg. This concludes the effectiveness of Gentrin® 300mg in the treatment by uterine infusion for pyometra.

The causes of pyometra are abnormal interactions between the uterus, circulating hormones and bacteria. Occurs in female dogs and cats. The use of contraceptives and undesirable mating can be predisposing factors. This disease is classified in two forms, the closed form is when the uterine cervix is occluded and presents an accumulation of infectious material, with an increase in uterine volume and a process of systemic intoxication. In the open form, there is expulsion of uterine secretion and milder clinical signs. The aim of this study was to report the treatment with the use of aglepristone and gentamicin in uterine infusion in two five-year-old pug dogs with pyometra. Two non-castrated bitches were treated at the Veterinary Hospital of a higher education institution, for presenting clinical signs compatible with pyometra. Assessments of hematological and biochemical parameters were performed. Where they were treated with the uterine lavage method with Gentamicin Uterine Infusion and Aglepristone. In the blood count exams of the animals reported, alterations were observed in the white series of both bitches, these alterations being called leukocytosis by neutrophil in animal one and leukocytosis by neutrophil and eosinophilia in animal two. At the end of the treatment, complete recovery of the animals to pyometra can be observed. The treatment performed proved to be satisfactory with the use of gentamicin in the uterine lavage method. The bitches in the study will resume their reproductive activities, and artificial insemination is indicated to prevent the recurrence of the pyometra.

Las causas de la piometra son interacciones anormales entre el útero, las hormonas circulantes y las bacterias. Ocurre en perros y gatos hembras. El uso de anticonceptivos y el apareamiento indeseable pueden ser factores predisponentes. Esta enfermedad se clasifica en dos formas, la forma cerrada es cuando el cuello uterino se ocluye y presenta una acumulación de material infeccioso, con un aumento del volumen uterino y un proceso de intoxicación sistémica. En la forma abierta, hay expulsión de la secreción uterina y signos clínicos más leves. El objetivo de este estudio fue reportar el tratamiento con el uso de aglepristona y gentamicina en infusión uterina en dos perros pug de cinco años con piometra. Dos perras no castradas fueron atendidas en el Hospital Veterinario de una institución de educación superior, por presentar signos clínicos compatibles con piometra. Se realizaron evaluaciones de parámetros hematológicos y bioquímicos. Donde fueron tratadas con el método de lavado uterino con infusión uterina de gentamicina y Aglepristone. En los exámenes de hemograma de los animales reportados, se observaron alteraciones en la serie blanca de ambas perras, llamándose estas alteraciones leucocitosis por neutrófilos en el animal uno y leucocitosis por neutrófilos y eosinofilia en el animal dos. Al final del tratamiento, se puede observar la recuperación completa de los animales a la piometra. El tratamiento realizado resultó satisfactorio con el uso de gentamicina en el método de lavado uterino. Las perras del estudio reanudarán sus actividades reproductivas, estando indicada la inseminación artificial para evitar la recurrencia de la piometra.

A utilização de contraceptivos e cruzamentos indesejáveis podem ser fatores predisponentes. Essa doença é classificada sob duas formas, a forma fechada consiste quando a cérvix uterina encontra-se ocluída e apresenta acúmulo de material infeccioso, com aumento do volume uterino e processo de intoxicação sistêmica. Já na forma aberta, há expulsão da secreção uterina e sinais clínicos mais brandos. O objetivo deste trabalho foi relatar o tratamento com o uso de aglepristone e gentamicina infusão uterina em duas cadelas pug de cinco anos de idade com quadro de piometra. Duas cadelas não castradas foram atendidas em Hospital Veterinário de uma instituição de ensino superior, por apresentarem sinais clínicos compatíveis para piometra. Foram feitas avaliações dos parâmetros hematológicos e bioquímicos. Onde foram tratadas com o método de lavagem uterina com Gentamicina Infusão Uterina e Aglepristone. Nos exames de hemograma dos animais relatados, foram observadas alterações nas séries brancas de ambas as cadelas, sendo estas alterações denominadas leucocitose por neutrófila no animal um e leucocitose por neutrofila e eosinofilia no animal dois. Ao final do tratamento pode ser observada recuperação total dos animais para piometra. O tratamento realizado revelou-se satisfatório com o uso da gentamicina no método de lavagem uterina. As cadelas do estudo retomarão as atividades reprodutivas, sendo indicada a inseminação artificial para evitar a recidiva da piometra.

This study aimed to evaluate the performance and the blood biochemical and physiological parameters of Dorper × Santa Ines lambs receiving three levels of metabolizable energy (ME). A completely randomized design with three treatments (ME levels) and eight replicates (lambs) was used. Twenty-four non-castrated male lambs of four months of age and 21.07 ± 3.91 kg body weight (BW) received a diet composed of 40% Tifton 85 hay and 60% concentrate feed, on a dry matter basis. The amount of feed supplied was adjusted to meet 115, 201, and 288 kcal ME per kg of metabolic weight (MW = BW0.75) daily. Average daily gain and the intake of dry matter (g/day and % BW0.75/day), nutrients, and energy increased linearly (P < 0.001) with ME level. The dry matter intake relative to BW (% BW/day) and feed conversion ratio showed quadratic responses (P < 0.05) to ME level. Serum creatinine decreased linearly (P = 0.038), whereas plasma glucose increased linearly (P = 0.045) with ME level. Serum urea presented a high variation (standard error range = ±1.98–6.07 mg/dL) in response to 288 kcal/kg0.75/day of ME supply, and did not stabilize during the trial. Respiratory rate increased linearly (P < 0.001) with ME level at each time of day (morning/afternoon), but with higher intensity in the afternoon. Heart rate and rectal temperature increased linearly (P < 0.001) with ME level. Given that the range of ME level simulated a restricted-to-ad libitum ME intake, the best response in terms of feed efficiency can be obtained with 252 kcal/kg0.75/day of ME supply, which probably reflects the best balance of metabolic and physiological parameters. Thus, in order to achieve high productive performance in tropical environments, feedlot lambs should be fed with high-concentrate diets.

Frota de pequena escala sediada em Matinhos (PR), operante com redes de emalhe, foi monitorada em 2014/2015. As redes possuem tamanhos de malha variando de 5 a 45 cm entre nós opostos, altura de 2 a 25 m, comprimento total de 400 a 4.000 m. Quatro modalidades de uso são comuns: fundeio e caceio (passivas), cerco e caracol (ativas). Tais modalidades são empregadas em sete técnicas, reunindo combinações de petrechos, locais de operação e sazonalidade, para capturar determinados recursos. São pescarias multiespecíficas, envolvendo ao menos 34 espécies de teleósteos e 11 de elasmobrânquios (maioria capturada na modalidade fundeio e como fauna acompanhante). Tainhas, pescadas, linguados e cações estão entre os recursos-alvo. No entanto, certos recursos são alvos numa modalidade, mas fauna acompanhante noutra. Em consequência das peculiaridades das técnicas, indivíduos pequenos são vulneráveis às malhas maiores, e os maiores, às malhas menores, fatos que dificultam o manejo por tamanho. Segundo categorias IUCN, três recursos tratam-se de espécies NT; sete VU; um EN; e dois CR. A técnica de fundeio malha 10 incide sobre três deles. A malha 18 sobre nove, no inverno e/ou primavera. Embora, ao menos 41 recursos ocorram permanentemente na região, a pesca de emalhe incide mais intensamente sobre 17, indicando que o rodízio de técnicas pode refletir uma menor pressão de pesca sobre a comunidade ictíica local. Recomenda-se redução do esforço de pesca da rede com malha 18 na técnica de fundeio no final de inverno e na primavera por capturar proporcionalmente um maior número de espécies ameaçadas.
