The southern red mite, Oligonychus ilicis (McGregor) (Acari: Tetranychidae) can cause a significant reduction in the photosynthesis potential and the growth of new coffee plants (Coffea spp., Rubiaceae). Studies suggest that the leaf spraying of silicon (Si) leads to increase plants resistance in order to reduce infestations of insect pests such as herbivores, borers, sucking insects and mites. The objective of this study was to evaluate the effect of leaf spraying of potassium silicate (K2SiO3) to control the southern red mite in coffee plants. Experiments were conducted in coffee plants (Coffea arabica L.), grown in a greenhouse, by means of completely randomized design with six treatments: Dose 0 (control), 2, 4, 6, 8 and 10 liters of silicate potassium ha-1 and five replications. Plants treated with potassium silicate, regardless of the applied dose, had a lower O. ilicis infestation compared to the control, not allowing the population increase, thus a smaller damage in coffee leaves. The silicon content in leaves was higher in plants treated with the highest dose of potassium silicate. It was observed that there was induction of defense molecules such as tannins and lignin in plants sprayed with potassium silicate. It was concluded that the potassium silicate applied in leaf spraying had positive effect on reducing O. ilicis attack in coffee plants, even being a dicot. Therefore, the applications of potassium silicate by leaf spraying can be used in programs of integrated management of the southern red mite in coffee, with a view to sustainable management and environmental protection.

Mites belonging to the family Phytoseiidae are the most important and most widely studied among predatory mites of phytophagous mites. The phytophagous mites Brevipalpus phoenicis (Geijskes, 1939) (Tenuipalpidae) and Oligonychus ilicis (McGregor, 1917) (Tetranychidae) on coffee (Coffea spp.), are frequently found in combination with the predaceous mites Iphiseiodes zuluagai Denmark & Muma, 1972;Euseius alatus DeLeon, 1966 and Amblyseius herbicolus (Chant, 1959) (Acari: Phytoseiidae), among others. The purpose of this research was to study the effects of the product CyazypyrTM (cyantraniliprole 100 OD) on these three species of Phytoseiidae, relevant to coffee, citrus and other agricultural crops in Brazil, following standard laboratory procedures. Mated female mites were exposed to fresh-dried residues on a glass surface, with 8 treatments, 5 mites per glass plate and 6 replicates, in a completely randomized experimental design. Each test lasted eight days, with a daily count of the surviving females and of eggs laid. CyazypyrTM, in all tested doses (75, 100, 125, 150, 175 and 200 g a.i./ha), was selective for the studied species, A. herbicolus, I. zuluagai, and E. alatus. Overall the treatments resulted in low mortality rates and negligible impact on the reproduction. Therefore, based on IOBC standards, CyazypyrTMcan be classified as not harmful (class 1) or slightly harmful (class 2), comparable to the agrochemical TalentoTM (hexythiazox 500 WP-12 g a.i./ha) equivalent to a harmless standard of selectivity in the laboratory. CyazypyrTM is therefore a complement to programs of integrated pest management, to preserve the populations of predatory mites in crops of coffee and citrus, among others, in Brazil.

The species of mite Oligonychus ilicis (McGregor) (Tetranychidae) is an important pest of dicotyledonous plants, cosmopolitan and polyphagous, reported in seven countries from four continents, feeding on 34 plant species of 15 families. The spider mite O. ilicis is known in Brazil as coffee red spider mite, and as southern red mite most in other countries. In Brazil O. ilicis has been reported as the second most important pest of “Conillon” coffee, Coffea canephora Pierre & Froehner, in the state of Espírito Santo. Depending on the number of mites per leaf of arabica coffee, Coffea arabica L., the rate of potential photosynthesis can be reduced by 37% to 50%. In the present study, it was investigated the potential of the two predatory mites which, among others, naturally occurs in coffee plantations, Euseius alatus DeLeon and Amblyseius herbicolus (Chant) (Phytoseiidae), in the control of O. ilicis in coffee plants. It was used potted coffee plants in this research, with approximately 100 cm high, growing in a greenhouse covered with transparent plastic and shading material of 50% sun protection factor, and with fine mesh on all the sides. Results showed that both species of predatory mites, A. herbicolus and E. alatus, are efficient in reducing the mobile phases—larvae, protonymphs, deutonymphs and adults—of the southern red mite O. ilicis. So, the importance of conservation and increase number of these predatory mites in the field coffee growing is essential for implementing the southern red mite integrated management tactic, since these species are of natural occurrence in coffee plants.

Predatory Potential of Phytoseiulus macropilis(Banks)Preying on Tetranychus urticae Koch(Acari:Phytoseiidae,Tetranychidae)

引用

Advances in Entomology 2018年第2期6卷 134-147页

作者： Giselle Christiane Souza-Pimentel paulo rebelles reis Gilberto Rodrigues Liska Marcelo Angelo Cirillo Postgraduate Program Universidade Federal de Lavras-UFLALavrasBrazil Empresa de Pesquisa Agropecuária de Minas Gerais-EPAMIG Sul/EcoCentro LavrasBrazil Universidade Federal do Pampa-UNIPAMPA Rio Grande do SulBrazil Departamento de Ciencias Exatas Universidade Federal de Lavras-UFLALavrasBrazil

The two-spotted spider mite, Tetranychus urticae Koch (Tetranychidae), is considered one of the most important species of pest-mites because it is cosmopolite and polyphagous. This species has been described as attacking over 1,100 plant species in 140 families of economic importance. On the other hand, Phytoseiulus macropilis (Banks) (Phytoseiidae) is a predatory mite of group I, specialist as predatory mite from the Tetranychus genus. Thus, the objective of this work was to evaluate predatory potential of P. macropilis in its different stages—nymphs, female and male adults—preying on T. urticae also in different stages—eggs, larvae, nymphs, and adults—and to know the functional and numerical responses in lab studies. Both the experiments were carried out on arenas made of Jack-bean leaflets’ discs [Canavalia ensiformis (L.)—Fabaceae] with 3 cm in diameter over agar-water at 3% inside 5 cm in diameter uncapped Petri dishes. To know the predatory activity, forty T. urticae and one predatory mite were placed in each arena with the respective phases of the developmental life cycle to be evaluated. To know the potential of predation, the no killed mites were counted after 24 hours. To know the functional and numerical responses, immature T. urticae in densities of 1 to 300/arena were offered for P. macropilis. The results for the predatory potential showed that larvae and male adult of T. urticae were the most killed stages, and the female predatory mites were the one that consumed most prey. The functional response showed a positive and significant correlation, suggesting a type II functional response (convex), a cyrtoid curve rising at a decreasing rate to a plateau, where the consumption remains constant regardless of prey density.

Objective: This case report aimed to demonstrate a possible neuromuscular effect of pyloric sympathectomy on the pylorus motility, leading to its permanent relaxation, observed in two bariatric surgical cases, one primary and the other, revisional. Background: Pyloric sphincter is a physiological barrier to free gastric emptying. In sleeve gastrectomy and in Roux-en-Y gastric bypass revisions, that put the remnant stomach in transit, the pylorus can contribute to generate a high intragastric pressure, which could lead to acute gastric fistulas and/or chronic gastroesophageal reflux disease. The possibility of functionally relaxing the pylorus, promoting intragastric pressure reduction, could represent a protective maneuver against these complications. Methods: We describe herein a surgical maneuver applied in two cases of bariatric surgeries, with the intention of facilitating antrum-duodenal region exposure, in a sleeve gastrectomy and in a Roux-en-Y gastric bypass conversion to SADI-S. For this, a ligation of terminal peripyloric vessels was done, allowing a passage of a tape, which surrounded the pylorus, for its traction. In both cases, 30-day and 1-year endoscopic evaluations were done, to assess esophagitis signs, anastomosis healing and anatomical pouch aspect. A clinical evaluation was also done, to assess gastroesophageal symptoms (validated questionnaire). Results: In the postoperative endoscopic evaluations, no esophagitis were observed in any case and the gastric pouches had normal aspect, with the expected anatomical findings, compatible with the surgeries performed. The anastomosis healed without problems, in the revisional case. Interestingly, in both cases, it was observed a complete pyloric sphincter relaxation, which lasted until 1-year endoscopic evaluation. There were no fistulas, nor esophagitis in any of these cases. Clinically, there were no symptoms of gastroesophageal reflux disease (validated questionnaire). Conclusion: The observation of a

Objective: This case report aimed to demonstrate a possible neuromuscular effect of Latarjet nerves transection or truncal vagotomy, in association with sleeve gastrectomy plus antrojejunostomy, in order to reproduce a Roux-en-Y gastric bypass (RYGB) mechanistic principles, in patients with previous Sleeve Gastrectomy (SG) who had had weight regain, with or without concomitant gastroesophageal reflux disease (GERD). Background: Sleeve gastrectomy (SG) is one of the most frequently performed bariatric operations worldwide. Nevertheless, weight regain and gastroesophageal reflux disease (GERD) have been consistently demonstrated, in association with this technique, which may require a revisional procedure. RYGB is an option in such a situation but, implies in gastrointestinal exclusions, which represents a shortcoming of this revision. Surpassing this inconvenient would be of great value for the patients. Methods: We describe herein two cases of SG revision for weight regain and GERD, with a follow-up of one year. Gastroesophageal reflux disease was evaluated by validated questionnaire, upper endoscopy, seriography, high resolution manometry (HRM) and impedance pHmetry (I-pHmetry), in the pre and postoperative periods. A re-Sleeve Gastrectomy with antrojejunal anastomosis was done in both cases, after informed consents. The Latarjet nerves were transected in one case, due to a bleeding in the left gastric vessels and a truncal vagotomy was required in the other, to appropriately treat an associated hiatal hernia. Results: In the postoperative evaluation it was observed a pyloric spasm in both cases, during seriography and endoscopy, kept until the one-year follow-up. There was unidirectional contrast flow to the gastrointestinal anastomosis, filling the jejunal limb, in radiologic contrast study. No contrast passed through the pylorus. Nonetheless, the duodenum was kept endoscopically accessible. In the one-year evaluation, weight loss was adequate and GERD resolution

Obesity is a significant and escalating health issue both in Brazil and globally, with over 650 million overweight adults worldwide. The treatment of obesity can be performed clinically, endoscopically or surgically;surgical treatment proves to be safe and more effective in terms of weight loss and long-term maintenance. Objective: This study aimed to monitor the progress of weight loss and comorbidity control in patients undergoing sleeve gastrectomy with duodenal bipartition. Methods: This pilot project involved 8 patients divided into 2 arms. In the first arm, patients underwent sleeve gastrectomy with Roux-en-Y duodenoileal transit bipartition (S-RYDITB), while in the second arm, patients underwent sleeve gastrectomy with Roux-en-Y duodenojejunal transit bipartition (S-RYDJTB). Both procedures involved Roux-en-Y reconstruction without duodenal exclusion. In S-RYDITB, the duodenal-ileal anastomosis was performed 300 cm from the ileocecal valve (ICV), creating a 250 cm common channel and a 50 cm alimentary channel. In S-RYDJTB, a biliopancreatic loop was created 200 cm from the angle of Treitz, with a 1 m alimentary channel. Results: Five patients underwent the procedures, with one undergoing S-RYDITB and four undergoing S-RYDJTB. No adverse events such as hospitalizations, readmissions, reoperations, fistulas, bleeding, pulmonary embolism, diarrhea, dumping syndrome, or hypoglycemia occurred during the study period. The mean length of hospital stay was 2 days. The average BMI decreased from 37.27 kg/m2 preoperatively to 29.48 kg/m2 after 6 months. The significant percentage of weight loss was 21.22%, with excess weight loss of 63.6%. Ninety-five percent remission of comorbidities, including hypercholesterolemia, hypertriglyceridemia, diabetes, hypertension, steatosis, and pre-diabetes. Two patients underwent sleeve gastrectomy with duodenal bipartition using a single anastomosis. Conclusion: Duodenal switch surgery has gained worldwide recog

Objectives: The Brazilian Unified Health System (Sistema Único de Saúde−SUS) is the universal public healthcare system of Brazil that maintains a nationwide database of its patients. Our primary objective was to analyze regional and temporal trends, while our secondary goal was to establish correlations between states’ health economy status and their prostate cancer (PCa) epidemiology. Methods: We analyzed Brazil’s nationwide data on prostate cancer (PCa) incidence, mortality, and care gathered between 2013 and 2021 by the Information Technology Department of SUS (DATA-SUS), updated monthly using the International Classification of Diseases (ICD-10) code. Results: In the period, 273,933 new cases of PCa and 135,336 PCa deaths were reported in men aged 50 years or over in Brazil. The median annual PCa-specific incidence rate (PCSIR) ranged from 14.7 in the Southeast to 6.9 in the North region and the median annual PCa-specific mortality rate (PCSMR) ranged from 7.7 in the Northeast to 6.0 in the South region (per 10,000 men >50). The median annual mortality to incidence ratio (MIR) was highest in the North (0.88) and lowest in the Southeast region (0.44). There were significant regional differences in PCa treatment rates (per new cases); the Midwest region had the highest median annual surgery rate (0.63) while the North region had the highest median annual systemic therapy rate (0.75) and the lowest radiation therapy rate (0.06). Temporal analysis of the data showed significant change in annual rate trends after the year 2018 for PCSIR (coefficient [β] = +3.66, p < 0.001), any treatment (β = −0.06, p = 0.016), surgery ([SR] β = +0.05, p = 0.017) radiation therapy ([RTR] β = −0.06, p = 0.005) and systemic therapy ([STR] β = −0.10, p = 0.002). After the 2020 pandemic, annual PCSIR decreased (β = −2.15, p = 0.002) but annual PCSMR, MIR, and treatment rates remained stable. Correlation studies showed that the PCSIR was strongly negatively correlated with STR (p < 0.001)
