Abstract:
... Sporadic avian leukosis virus (ALV)-like bursal lymphoma, also known as spontaneous lymphoid leukosis (LL)-like tumors, were identified in commercial broiler breeder flocks in the absence of exogenous ALV infection. Two individual ALV subgroup E (ALV-E) field strains, designated AF227 and AF229, were isolated from two different breeder farms. The role of these ALV-E field isolates in development o ...

Escherichia coli; Musca domestica; Salmonella Typhimurium; adults; bacteria; cattle manure; digestive tract; disease transmission; farms; females; males; microbial load; nutrition; oviposition; risk assessment; sugars; virulent strains
Abstract:
... House flies, Musca domestica L., develop within and feed upon microbe-rich substrates such as manure, acquiring and potentially disseminating pathogenic bacteria. Because adult female flies frequent manure due to oviposition or nutrition requirements, we hypothesized females would consume more manure than males even in the presence of additional food sources (e.g. sugar), resulting in measurable d ...

Abstract:
... Aggregations of Thaumatomyia glabra (Diptera: Chloropidae) were observed on flowers of Iris pallida Lamarck (Asparagales: Iridaceae), whereas no T. glabra (Meigen) were observed on nearby Iris germanica L. flowers. Sampling of T. glabra on I. pallida flowers revealed the presence of males only. In a previous study, T. glabra males were attracted to methyl anthranilate. We found methyl anthranilate ...

Abstract:
... The trade-off between performance and stability in amorphous oxide semiconductor-based thin-film transistors (TFTs) has been a critical challenge, meaning that it is difficult to simultaneously achieve high mobility and stability under bias and light stresses. Here, an amorphous mixture of two indium-free BaSnO₃ and ZnSnO₃ compounds, a-(Zn,Ba)SnO₃, is proposed as a feasible strategy to achieve hig ...

Unfortunately, these insecticides are toxic to many bees and natural enemies and no longer control some pests that have developed resistance. Anthranilic diamide insecticides provide systemic control of many herbivorous arthropod pests, but exhibit low toxicity to beneficial arthropods and mammals, and may be ...
