Abstract Habitat fragmentation due to urbanization is known impact bees, the main group of pollinators. However, we still do not know effects on stingless bees (Meliponini), most diverse eusocial with high recruiting and pollinating capabilities. To fill this gap, studied occurrence key species Melipona quadrifasciata in a large metropolis Brazil. We used comprehensive sampling involving local landscape variables. The first was composed (1) degree disturbance, (2) fragment size, various fieldwork‐based phytosociological data, such as (3) tree richness, (4) abundance, (5) density, (6) canopy height. Landscape variables included degrees (7) surroundings (8) isolation from other fragments. found that occurred only 54.54% sampled fragments, indicating presumably widespread distribution may become locally extinct. Places where occurs have characteristics distinctive those it absent. Fragment area indicators good forest vegetation structure, including were correlated each determined since they are more likely provide nesting places old trees floral resources.

These results suggest both factors associated availability quality determine persistence across Since presence formed correlation modules, can be collectively suitability urban conservation management strategies aiming sustain these important pollinators essential ecosystem services provide.

While olive trees are primarily wind-pollinated, biodiversity-friendly management of the groves can contribute to conservation pollinating insects in agroecosystems. Previous research demonstrated that semi-natural habitats, such as herbaceous linear elements and woody areas, support community pollinators Less is known about contribution low-input with a permanent ground cover on terraced landscapes. This study investigated relationship between pollinator communities including spontaneous vegetation, traditional Mediterranean grove agroecosystem. The employed pan traps monitor wild bees observation walks assess butterfly across three different habitat types spring, summer, autumn during two growing seasons. Floral resources habitats were assessed each sampling time. Analysis showed higher abundance than while do not differ significantly from either type, despite exhibiting highest floral abundance. suggests structure, rather availability alone, plays role maintaining bee community. For butterflies, results demonstrate overall does species composition does. emphasizes importance preserving diverse particular groves, within agricultural landscapes wide range species.

Brassica campestris L. var. toria, a major oilseed crop cultivated in India, is primarily an entomophilic species. Hymenopteran flower-visiting species provide important ecological services like pollination or pest control crops. In this context, study was conducted during 2015–2017 three localities Assam, state northeast India that falls under two global biodiversity hotspots—Indo–Burma and Himalayan—to bring data on the diversity of hymenopteran flower visitors toria crops by using multiple sampling techniques to compare efficiency these techniques. Altogether, nine treatments were used. To assess effectiveness different treatments, from cropping periods each locality analysed cumulatively comparatively. Variable transect outperformed other methods with highest number visitor recorded at 54, representing 84.4% total species, followed standard (34 53.1%), elevated yellow trap (22 34.4%), observation plot (21 32.8%). However, importance noticed; one method alone could not sample all recorded. The cluster traps netting walks proven be complementary considered useful for future research studies upstream basin Burhidihing River India.
