Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Microbial communities of three sympatric Australian stingless bee species. [PDF]

PLoS ONE, 2014
Bacterial symbionts of insects have received increasing attention due to their prominent role in nutrient acquisition and defense. In social bees, symbiotic bacteria can maintain colony homeostasis and fitness, and the loss or alteration of the bacterial

The Wonders of Vanilla: Celebrating the 150th Anniversary of Synthetic Vanillin

ChemFoodChem, Volume 2, Issue 2, June 2026.
The year 2024 marked the 150th anniversary of the first commercial production of vanillin, one of the world's most cherished flavor ingredients. This review traces vanilla's history from Mesoamerica to modern production methods, examines its composition, the discovery of vanillin and Haarmann's early synthesis compared to modern methods, and highlights

Machine Learning and Geospatial Modeling of Climate Change Impacts on Ethiopian Honeybees for Conservation and Resilient Agriculture

Ecology and Evolution, Volume 16, Issue 6, June 2026.
The current study used machine learning and geospatial analysis to predict how climate change will loosen and fragment suitable habitats for Ethiopian honeybees. Main factors like agro‐ecological zones and dry‐season precipitation were found to be critical for bee survival.

Microbial Pressure and Social Immunity: Bumble Bees Increase Brood Hygiene After Exposure to a Bacillus thuringiensis‐Based Biopesticide

Ecology and Evolution, Volume 16, Issue 6, June 2026.
In social insect colonies, diseased or dead brood is identified and removed by workers to prevent the infection of the whole colony. Here, bumble bee larvae exposed to a bacterium (Bacillus thuringiensis ssp. aizawai (strain: ABTS‐1857)) based biopesticide were removed more frequently than wounded or untreated control larvae. This shows that bumble bee

Indigenous Knowledge, Habitat, and Nest Characterization of Stingless Bee (Meliponula beccarii) in West Arsi Zone of Oromia, Ethiopia

Psyche: A Journal of Entomology
Stingless bees are eusocial insects that play vital roles as pollinators of many flowering plants and high value products. However, information on their nesting habitats and nest characteristics is scarce in West Arsi Zone of Oromia, Ethiopia. This study

Hygienic behaviour in Brazilian stingless bees

Biology Open, 2016
ABSTRACT Social insects have many defence mechanisms against pests and pathogens. One of these is hygienic behaviour, which has been studied in detail in the honey bee, Apis mellifera. Hygienic honey bee workers remove dead and diseased larvae and pupae from sealed brood cells, thereby reducing disease transfer within the colony ...

Harvesting the Casualties of War: Macrogerodonia peruviana Rove Beetles Prey Exclusively Upon Wounded Trigona spp. Stingless Bees (Coleoptera: Staphylinidae; Hymenoptera: Apidae)

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We report a previously undescribed trophic interaction in which Macrogerodonia peruviana rove beetles prey exclusively on wounded or recently killed Trigona stingless bees generated during aggressive conflicts at carrion. Field observations and choice experiments showed that beetles selectively targeted injured Trigona while ignoring carrion and other ...

Distance and habitat drive fine scale stingless bee (Hymenoptera: Apidae) community turnover across naturally heterogeneous forests in the western Amazon

Sociobiology, 2014
High tree species richness in the western Amazon has been attributed to heterogeneous soils, which harbor edaphic specialist trees. While rapid transitions in tree communities are well documented across these variable soils few studies have investigated ...

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

Functional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.
