Contaminant-driven midgut histological damage in bees and other aculeate Hymenoptera: a quantitative review

Environmental Toxicology and Pharmacology, Год журнала: 2025, Номер unknown, С. 104670 - 104670

Опубликована: Март 1, 2025

We present a review about histological sub-lethal effects due to anthropogenic contaminants on the midgut of bees and other aculeate hymenopterans. Contaminant types, damage methodology were extracted summarized from 74 published articles, then quantitatively analyzed. found that western honeybee (Apis mellifera) is by far most widely used model. Contaminants have largely been tested under laboratory conditions, particularly insecticides fungicides. Tissue-level (e.g., degradation epithelium peritrophic membrane) often detected together with cell-level cell vacuolisation, karyorrhexis). Descriptive statistics mixed models suggested herbicides may cause specific mix alterations an overall lower severity compared pesticides, while combined use light electron microscopy seemed detect more types. claim for efforts reduce biases in future studies such effects, allowing their clearer as markers human activities.

Sublethal Effects Induced by a Cyflumetofen Formulation on Honeybee Apis mellifera L. Workers: Assessment of Midgut, Hypopharyngeal Glands, and Fat Body Integrity

Worldwide, both cultivated and wild plants are pollinated by the honey bee, Apis mellifera. Bee numbers declining as a result of variety factors, including increased pesticide use. Cyflumetofen controls pest mites in some plantations bees, which may be contaminated with residual sublethal concentrations this pesticide, nectar pollen. We evaluated effects concentration cyflumetofen formulation on midgut, hypopharyngeal gland, fat body A. mellifera workers orally exposed for 72 h or 10 days. The midgut epithelium treated bees presented digestive cells cytoplasm vacuoles cell fragmentation, indicating autophagy death. After being to h, showed higher injury rate than control but after days, organs had recovered. In gland end apparatus was filled secretion, suggesting that acaricide interferes secretory regulation gland. Histochemical tests revealed differences exposure periods glands. caused cytotoxic cells, apical protrusions, plasma membrane rupture, several cytoplasm, features degeneration. glands small electron-dense large electron-lucent granules. no changes comparison bees. conclusion, at causes damage compromise functions these colony fitness.
