Brazil has a wide diversity of species stingless bees the tribe Meliponini, with 244 described species. In last decade, after reported decline in bees’ colonies, have been used as study model toxicological assessments tropical regions. These consider mainly risks associated exposure to agrochemicals, which can affect health these essential pollinators and consequently compromise their ecosystem services. The present aimed (a) review literature considering agrochemicals Brazil, (b) provide big picture scenario trends research on interaction 76 years, including species, methods tested (c) adapted protocols for carrying out bees; (d) assess lethal sublethal effects larval bee Partamona helleri different agrochemicals. Data from meta-analysis (implementing artificial intelligence) underwent identification, screening, eligibility inclusion phases, were analyzed according via development stage. number studies particularly insecticides, increased over decade. However, cover only 2.9% Brazil. Toxicological comprise order Hymenoptera (Apidae), emphasis Apis mellifera. group especially neonicotinoids, most studied main route was acute under laboratory conditions. here successfully validated, exhibiting high survival rate between 80 – 100% control treatment chronic larvae adults, respectively, is necessary satisfy regulatory authorities. orally treated three affected, dose type compound, recommended field doses copper sulfate (CuSO4), spinosad highly toxic, unlike glyphosate. Locomotion altered adults derived larvae, gut microbiota composition did not change by agrochemical. It conclude that systematic reviews, description assessing possible improve knowledge regarding role play bees, well point gaps need be filled. this way, data obtained comprehensive overview may suffering because human activities.

Cross-resistance to medical azoles by exposure azole pesticides is well documented for Aspergillus family fungi but poorly evaluated other environmental pathogen fungi, particularly yeasts belonging the Cryptococcus neoformans/Cryptococcus gattii species complexes.One thousand C. neoformans yeast were exposed various concentrations of seven different commonly used pesticides. Clones surviving picked randomly, and their minimal inhibitory (MICs) fluconazole, voriconazole, posaconazole, itraconazole isavuconazole assessed.Depending on pesticide exposure, up 13.3% selected colonies showed a phenotype resistance among them, several cross-resistance another or azoles. Molecular mechanisms involved in setups seem be dependent ERG11 AFR1 gene overexpression.Exposure any tested capable increasing MIC fluconazole neoformans, including level fluconazole-resistant phenotype, as generating some cases.

Sustainable production of pumpkin (Cucurbita maxima Duchesne) partly relies on integrated pest management (IPM) and pollination services. A farmer-managed field study was carried out in Yatta Masinga Sub-Counties Machakos County, Kenya, to determine the effectiveness a recommended IPM package its interaction with stingless bee colonies (Hypotrigona sp.) for pollinator supplementation (PS). The comprised Lynfield traps cuelure laced organophosphate malathion, sprays Metarhizium anisopliae (Mechnikoff) Sorokin isolate ICIPE 69, most widely used fungal biopesticide sub-Saharan Africa, protein baits incorporating spinosad. Four treatments-IPM, PS, (which combined PS), control-were replicated 4 times. experiment conducted 600 m2 farms 2 normalized difference vegetation index (NDVI) classes during growing seasons (October 2019-March 2020 March-July 2020). Fruits showing signs infestation were incubated emergence, fruit fly trap catches counted weekly, physiologically mature fruits harvested. There no effect IPM, NDVI yield across seasons. This revealed synergistic between PS suppressing Tephritid population densities damage. Hypotrigona sp. is not an efficient pumpkin. Therefore, we recommend testing other African bees systems better services improved yields.

Abstract The commercial stingless bee Heterotrigona itama naturally nests in tree cavities but was kept wooden boxes meliponiculture farms. However, at Universiti Malaysia Sabah (UMS), these bees primarily nest lamp posts. We conducted a temperature survey to assess posts as potential nesting sites for H. itama, aiming determine if the preference occupied related their distribution. measured ambient temperatures shaded areas and unoccupied exposed on UMS campus, calculating percentage of time fell outside optimal range itama. Additionally, we analyzed occurrence timing regulation post by comparing differences between across four-time blocks. Temperature measurements (shaded) (exposed) revealed that experienced bees' (27°C-32°C) less often than (68.4% vs. 78.12%). This suggests may prefer due more stable profile. internal posts, whether or not, consistently 1.54–1.76°C warmer during hotter periods closer cooler periods, indicating inherent insulation properties metal notable difference observed late afternoon evening, suggesting active thermoregulation maintain temperature.

Abstract Over the last few decades, agrochemicals have been partially associated with a global reduction in bees. Toxicological assessment is crucial for understanding overall agrochemical risks to stingless Therefore, lethal and sublethal effects of commonly used crops (copper sulfate, glyphosate, spinosad) on behavior gut microbiota bee, Partamona helleri , were assessed using chronic exposure during larval stage. The recommended field doses CuSO 4 (200 Active Ingredient, a.i., µg) spinosad (8,16 a.i. reduced survival, but not glyphosate (148 µg). No significant adverse bee development observed any treatment or increased number deformed bees their body mass. Agrochemicals changed composition adult bees, metals such as copper accumulated bees’ bodies. response depends class dose ingested compound.
