Histomorphology Structure of the Gastric Caecum, Midgut, and Malpighian Tubules in Adult Flatheaded Pine Borer Chalcophora mariana (Linnaeus, 1758) (Coleoptera: Buprestidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT The pine weevil is one of the largest species in the jewel beetle (Buprestidae) family found in Central Europe and Turkey. Chalcophora mariana is generally considered a secondary guest and primarily develops in weakened, decaying, or recently dead pine trees.

Morphology and Chemical Characterization of the Metathoracic Scent Gland in Halyomorpha halys (Stål, 1855) (Hemiptera: Heteroptera: Pentatomidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Halyomorpha halys (Stål, 1855) is an invasive pentatomid species causing considerable economic losses in agricultural systems. Despite the ecological importance of the metathoracic scent gland (MTG) in chemical defence and communication, detailed information on its morphology and secretion composition remains limited. In the present study, the

Life‐History Traits and Overwintering of Actia interrupta (Diptera: Tachinidae), a Larval Parasitoid of Choristoneura fumiferana (Lepidoptera: Tortricidae)

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Actia interrupta is a larval tachinid parasitoid that plays a key role in regulating low‐density populations of the eastern spruce budworm. We describe its immature stages, life‐history traits, host‐searching behavior, development, and confirm its larviparous reproductive strategy.

Hemolymph amino acid analysis of individual Drosophila larvae

open access: yes, 2008
International audienceOne of the most widely used transgenic animal models in biology is Drosophila melanogaster, the fruit fly. Chemical information from this exceedingly small organism is usually accomplished by studying populations to attain sample ...

Effects of Cold Stress on the Hemolymph of the Pacific White Shrimp Penaeus vannamei

open access: yesFishes
Temperature is an important factor in the physiological processes of aquatic organisms and can seriously affect several chemical and biological processes in their bodies, including respiratory metabolism, antioxidant capacity, immune capacity, and signal

Cypermethrin induced toxicity to phosphatases and dehydrogenases in gills and hemolymph of fresh water crab, spiralothelphusa hydrodroma(herbst) [PDF]

open access: yesInternational Journal of Biological and Medical Research, 2011
The fresh water field crab, Spiralothelphusa hydrodroma is an important food source in parts of South India. The impact of cypermethrin on the variations in the enzyme activity of gills and hemolymph of the experimental female crab S.hydrodroma was ...

Microbiome‐mediated immunity: Limited support from the gazelle dung beetle

open access: yesEcological Entomology, EarlyView.
Digitonthophagus gazella rely on a maternally inherited microbiome passed across generations via a maternal faecal pellet called the pedestal. We experimentally manipulated the presence of the pedestal, providing it to some individuals while withholding it from others to determine how pedestal microbiota may affect beetle immune potential.

Aptamer‐mediated outer membrane destabilization overcomes low permeability resistance in Pseudomonas aeruginosa

open access: yesThe FEBS Journal, EarlyView.
DNA aptamers, Apt 60 and Apt 173, target the BamA protein to compromise outer membrane integrity in Pseudomonas aeruginosa, making it susceptible to Azithromycin, an antibiotic that is otherwise poorly effective due to the low‐permeability membrane.

Circadian rhythms of metabolite abundance in Drosophila are largely driven by time of feeding

open access: yesThe FEBS Journal, EarlyView.
Circadian clocks exist in the brain and peripheral tissues such as the Drosophila fat body. Single‐nuclei transcriptomics reveal that the fat body clock generates time‐of‐day differences in metabolic gene transcription, which may also be indirectly controlled by brain clocks.
