The Biochemistry of Insect Hemolymph [PDF]

Annual Review of Entomology, 1961
α,α-Trehalose, a sugar previously regarded as a product characteristic of certain lower plants, has been identified as a major blood sugar of insects. Trehalose has been isolated in pure form from the blood of pupae of the silk moth, Telea polyphemus , and has been recognized chromatographically in all the insects examined, which comprise 10 species ...

Glucosinolate hydrolysis products suppress entomopathogenic nematodes in vitro but do not protect sequestering flea beetle larvae in vivo

Pest Management Science, Volume 82, Issue 4, Page 3603-3612, April 2026.
The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...

Non‐Canonical, Somatic‐Dependent Vertical Transmission of Wolbachia in an Aphid

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
We discovered a novel somatic‐associated Wolbachia transmission strategy in cedar bark aphids (Cinara cedri), contrasting with its typical maternal vertical transmission. This unique maternally retained somatic re‐acquisition strategy—a “piggybacking” on the highly efficient obligate symbiont transmission pathway—reveals diverse endosymbiont strategies

Rainfall shapes the physiological condition, but not the body size, of an introduced dung beetle in Brazilian pastures

Ecological Entomology, Volume 51, Issue 2, Page 346-355, April 2026.
Understanding rainfall‐driven physiological shifts in dung beetles is crucial to predict how climate change may affect the fitness and persistence of key insect species in tropical pastures. We compared body size, dry, lipid and muscle masses of Digitonthophagus gazella collected during dry and rainy seasons in Brazilian pastures to assess the effects ...

Unexpected Evolutionary Divergence of Tachykinin‐Positive Neurons Innervating the Central Complex in Hexapods

Journal of Comparative Neurology, Volume 534, Issue 3, March 2026.
The central complex is a group of midline‐spanning neuropils in the brain of insects with a key role in goal‐directed orientation and navigation. Immunolabeling in 25 species, ranging from bristletails to flies, shows that neurons containing peptides of the tachykinin family of neuropeptides are present in most species studied.

Antioxidant Activities in the Hemolymph and Fat Body of Physiologically and Prematurely Aging Bees (Apis mellifera)

Antioxidants
Aging is a multifactorial process that occurs in all living organisms, including bees. One of the factors accelerating this process is stress caused in bees by Varroa destructor.

Genetic Basis of Cuticular Hydrocarbon Variation in the Desert Ant Cataglyphis niger

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Cuticular hydrocarbons (CHCs) are a ubiquitous component of ant cuticles that are used for a wide range of chemical signaling functions, especially recognition. Here we tested for a genetic basis of CHC variation in the desert ant Cataglyphis niger. We applied a genomic mapping approach to discover associations between CHCs and 20 quantitative trait ...

Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review

Food Frontiers, Volume 7, Issue 2, March 2026.
Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.

Concentration of the Total Hemolymph Protein of the Australian Red-clawed Crayfish (Cherax quadricarinatus, Von Martens 1868) Grown in Artificial Conditions [PDF]

Journal of Stress Physiology & Biochemistry
Aim. The concentration of total protein in the hemolymph of the Australian red-clawed crayfish Cherax quadricarinatus, Von Martens 1868, contained in artificial conditions in closed water supply installations and an aquarium complex, was studied ...

Bacteriophage Therapy: Current Strategies and Future Perspectives

MedComm, Volume 7, Issue 3, March 2026.
This manuscript systematically reviews the expanding scope of phage applications. It moves beyond traditional antibacterial use to explore their role in precision therapies against drug‐resistant infections, their synergy with antibiotics, and advanced biomaterial‐assisted delivery systems.
