Coupling several natural and synthetic lures with aggregation pheromones from the palm weevils Rhynchophorus palmarum and R. ferrugineus reveals a synergy that results in an increase in pest captures. The combined attraction of pure pheromones, ethyl acetate, and decaying sweet and starchy plant tissue increases the net total of mass-trapped weevils. The 2018 entrance of the red palm weevil (RPW) into South America has threatened palm-product income in Brazil and other neighboring countries. The presence of the new A1 quarantine pest necessitates the review of all available options for a sustainable mass-trapping, monitoring, and control strategy to ultimately target both weevils with the same device. The effective lure-blend set for the mass-trapping system will attract weevils in baiting and contaminating stations for entomopathogenic fungi that the same weevils will spread.

Infertility and prenatal mortality are the most important causes of production losses in domestic animals. The presence of pathogenic agents in the female reproductive system of cattle can negatively influence the reproductive performance of the herd. The objective of this study was to isolate, quantify, and characterize the components of the vaginal microbiota of multiparous and nulliparous mongrel cows, focusing on proper health and reproductive management. Samples were collected from 20 healthy animals: 10 nulliparous and 10 multiparous cows. The inoculation was performed simultaneously on four different culture media: BBL CHROM agar Candida, BBL Bile Esculin Agar Slants, Baird-Parker Agar, and MacConkey Agar bile salts. The isolated microorganisms were identified according to morphological and biochemical features. Microorganisms were detected in 80% of the nulliparous and 10% of the multiparous cows, with the following frequency: 88.78% of bacteria had morphophysiological characteristics of Staphylococcus spp., 11.22% of Escherichia coli, and 120 isolated yeast colonies which were identified as Candida tropicalis (69%), C. albicans (24%), and C. krusei. Seventeen isolates of Staphylococcus spp. (53.12%) presented sensitivity to all antimicrobials tested: 65.6% to amoxillin, 46.9% to erythromycin, 71.8% to rifampicin, and 46.9% to tetracycline. The rate of resistance to antimicrobials (MDR) was 0.125. The presence of typical microorganisms was detected. The MDR indicated that the isolates did not show multiresistance, with only two (6.25%) resistant to more than one antimicrobial simultaneously. The bacterial isolates studied were sensitive to the antimicrobial drugs tested, demonstrating the potential for use of these active ingredients.

A caprinocultura é uma atividade com relevante importância socioeconômica para a região Nordeste brasileira, sendo praticada, principalmente, por pequenos produtores e em propriedades características de agricultura familiar. A quantidade e qualidade do leite é influenciada por parâmetros zootécnicos, especialmente por meio da sanidade dos animais. Assim, aspectos microbiológicos são importantes para com a prevenção e controle de enfermidades como a mastite subclínica. Diante disso, objetivou-se por meio desse trabalho o diagnóstico da etiologia de mastite subclínica em caprinos leiteiros no Estado de Alagoas. Foram colhidas de forma aleatória, 200 amostras de leite procedentes de 100 cabras em diferentes estágios de lactação oriundas de uma propriedade leiteira do município de Coité do Nóia no estado de Alagoas, Brasil. Os animais eram da raça Saanen, Toggenburg, Parda Alpina e mestiços, em diferentes graus de sangue criados de forma intensiva. Para o diagnóstico da mastite subclínica foi aplicado o California Mastitis Test (CMT). Para o exame microbiológico foram coletados individualmente dos antímeros mamários um volume de 10 ml em frascos com tampa rosqueável, esterilizados e previamente identificados com o número do animal. O isolamento bacteriano foi realizado através de plaqueamento em Ágar base acrescido de sangue ovino a 5%. Por meio das análises foi observado que Staphylococcusspp. foi o micro-organismo predominante como agente etiológico de mastite subclínica.
