Some properties of a mechanism delaying penetration of insecticides into houseflies

, 1970
The penetration of insecticides into houseflies, with and without the factor that delays penetration, was studied by measuring the amounts of the insecticides on the surface of the flies at intervals after treatment.

Characterization of Resistance Patterns and Detection of Apramycin Resistance Genes in Escherichia coli Isolated from Chicken Feces and Houseflies after Apramycin Administration

Frontiers in Microbiology, 2018
The aim of this study was to evaluate the influence of apramycin administration on the development of antibiotic resistance in Escherichia coli (E. coli) strains isolated from chicken feces and houseflies under field conditions. Chickens in the medicated

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females

Integrative Zoology, EarlyView.
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

Turmeric shortens lifespan in houseflies. [PDF]

Front Insect Sci
Climate change poses a significant threat to food security and global public health with the increasing likelihood of insect pest outbreaks. Alternative ways to control insect populations, preferably using environmental-friendly compounds, are needed.

Anatomy and Histology of the Midgut of Atopozelus opsimus (Heteroptera: Reduviidae)

Acta Zoologica, EarlyView.
ABSTRACT Atopozelus opsimus Elkins, 1954 (Heteroptera: Reduviidae) preys on forest and agricultural pests but also feeds on extrafloral nectar; however, its alimentary canal is poorly understood. The aim was to describe the anatomy and histology of the A. opsimus midgut. The alimentary canal of female and male A.

FLUORESCENCE OF HOUSEFLY VISUAL PIGMENT [PDF]

Photochemistry and Photobiology, 1984
Abstract —The fluorescence of housefly photoreceptors was studied in vivo by using the deep pseudopupil technique. Whereas the rhodopsin R490 of the peripheral retinular cells fluoresces negligibly the metarhodopsin M580 fluoresces distinctly in the red.

Fungal infection affects sexual signalling and mate choice in the sugarcane borer

Ecological Entomology, EarlyView.
Fungus‐infected Diatraea saccharalis females exhibit enhanced attractiveness to males in wind tunnel assays. Fungal infection alters the pheromone profile of females, increasing the relative abundance of Z9‐16: Ald, a minor but behaviourally active component of the species' sex pheromone blend.

Short-term particulate matter contamination severely compromises insect antennal olfactory perception

Nature Communications, 2023
The consequences of sub-lethal levels of ambient air pollution are underestimated for insects, for example, the accumulation of particulate matter on sensory receptors located on their antennae may have detrimental effects to their function. Here we show

Global Poultry Feed Protein Sources: Trends, Challenges, and Sustainability Perspectives Using FAOSTAT Data

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT The global poultry industry is one of the fastest‐growing livestock sectors, with worldwide chicken stocks exceeding 32 billion heads and meat production surpassing 144 million tonnes in 2024 (FAOSTAT, 2026). Conventional protein sources, particularly soybean meal (SBM) and fishmeal, underpin most commercial poultry diets but face mounting ...

73 days?! Examining the rate at which medical knowledge doubles and its implications

Medical Education, EarlyView.
Abstract The Issue: ‘Knowledge is accumulating faster than human‐beings have the capacity to assimilate it’. According to popular estimate, knowledge now doubles every 73 days, roughly the lifespan of a housefly. We need, therefore, to stop thinking of health professional education in terms of transmission of knowledge.
