Baseline toxicity levels to foliarly applied spirotetramat were established for 19 field populations of whiteflies, Bemisia tabaci (Gennadius) B biotype (=Bemisia argentifolii Bellows & Perring) (Hemiptera: Aleyrodidae) from Arizona and California in 2008 and 2009. The susceptibility data were determined against the second instar of B. tabaci field collections before the registration and widesp...

The article estimates the chances of the emergence of human cancer from its pre-sapiens predecessors. The approach of current investigation was based on the integration of recent achievements in evolutionary immunology, epidemiology, and paleo-anthropology with the development of initial results of recent investigation of the population differences in human susceptibility to cancer. The focus w...

Abstract Intraspecific variation in growth and defence among plant populations can be driven by differences (a)biotic conditions, such as herbivory resources. Introduction of species to novel environments affects simultaneously encountered a resource availability both directly via altered competitive environment. Here, we address the question how (leaf mass per area (LMA), size) resistance trai...

tetranychus urticae koch is an injurious pest of, fruit crops, crop plants as well as ornamental plants worldwide. the high reproductive potential of t. urticae and its fairly short life cycle along with the frequent application of acaricides usually required to maintain t. urticae populations below economic thresholds, facilitates the pest's resistance to acaricides, and consequently cont...

Introduction: Antibiotic resistance, especially in Gram-negative uropathogens such as Escherichia coli, is the main barrier to treat urinary tract infection (UTI). In recent years, the dramatically increased resistance of E. coli to quinolones, a group of widely used antibiotics, has become a significant concern. Methods: In this descriptive cross-sectional study, we collected 261 E. coli isola...

Ticarcillin and clavulanic acid in combination were tested against 40 Pseudomonas aeruginosa isolates resistant to ticarcillin by disk diffusion. A total of 21 isolates (53%) were susceptible to ticarcillin-clavulanate by disk diffusion, under currently recommended criteria for ticarcillin susceptibility. Macro-broth dilution tests (ticarcillin plus clavulanic acid, 2 micrograms/ml) confirmed s...

Background and purpose: Methicillin-resistant Staphylococcus. aureus (MRSA) is specific strain of S.aureus that is a major cause of nosocomial infection. Nowadays, Vancomycin is the first-line treatment of severe MRSA infections. However, resistance to Vancomycin is reported in the form of Vancomycin-resistant Staphylococcus aureus (VRSA) too. This study aimed at determining the prevalence of M...
