Therefore, we tested their effectiveness using watermelon, which is one of the most economically significant global food crops in terms of production volume and production value. Our study aimed at determining how bee body size, visitation rate, and bee-flower size matching ratio affect pollen deposition. We measured pollen deposition in combination with the morphometrics of 30 bees each and measurements of 30 corresponding flowers they visited. We calculated the bee-flower size matching ratio, the relationship between the bee size, and the flower measurement to gauge the effectiveness of each bee species on pollen deposition and distribution among the three watermelon stigmatic lobes. Our findings elaborate on how the different sizes of various bee parts majorly impacted the amount of pollen deposited. Besides, the number of visits, probing time, and bee behavior when handling the flower also played a role. Bees with a size matching ratio approaching 1 deposited more pollen on a single visit. However, pollen distribution highly depended on the number of visits. Among the stingless bee species, <i>Meliponula ferruginea</i> was the best performer<i>.</i> Though the honey bee species <i>Apis mellifera</i> was the best pollen depositor, its performance was almost similar to that of <i>M. ferruginea</i>. In fact, upon a single flower visit, <i>M. ferruginea</i> performed better than <i>A. mellifera</i>. Based on our findings, it can be concluded that stingless bees, particularly <i>M. ferruginea</i>, are effective pollinators of watermelon flowers. Furthermore, traits like probing time, multiple visits, or frequent visitation are not enough to gauge pollinator effectiveness, but there is also a need to include other traits like the size matching ratio between the bee body and flower head.</p></div>","PeriodicalId":8078,"journal":{"name":"Apidologie","volume":"55 4","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141548472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analysed the solution consumption and survival of <i>Bombus terrestris</i> L.

We found that consumption of nectar enriched with proline at twice the natural concentration was strongly positively correlated with bumblebee weight.

We did not find any direct effect of β-alanine on consumption, although our findings suggest a potential interplay between proline and β-alanine in the regulation of proline intake. Bumblebee survival was not affected by any nectar composition. These results suggest that the high visitation rate to flowers of <i>G. lutea</i> by bumblebees observed in natural populations can be partially related to its nectar amino acidic composition, and that protein and non-protein amino acids can affect pollinator preference and foraging behaviour.\u0000</p></div>","PeriodicalId":8078,"journal":{"name":"Apidologie","volume":"55 4","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141521043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By conducting a systematic review followed by a meta-analysis, we estimated the effect sizes of pesticide application on bees and their crop pollination service. Our results show that pesticides reduce bee survival almost five times. Even when bees survive, sublethal effects can impair crop pollination. The consequences for bee communities and their crop pollination service might not be immediately evident but can be magnified in the long-term. Finally, we conclude that conserving the vegetation surrounding crops and minimizing pesticide use are key to protecting bees and ensuring crop pollination.

Nectar sugar content is known to affect pollinator preferences, while the effect of other nectar nutrients on flower visitor choices is less well understood. To explore whether nectar nutrients affect the foraging preferences of the stingless bee <i>Trigona fulviventris</i>, we conducted feeding choice experiments with sucrose solution enriched with either an amino acid mixture (in high and low concentrations), sodium chloride (table salt), a fatty acid mixture, or quinine (a bitter tasting substance used as negative control) against pure sucrose solution in a lowland rainforest in Costa Rica. Bees were first trained to feeders presenting either a yellow (only sucrose solution) or a blue (sucrose solution plus tested substance) visual cue that the bees could use to associate with the solution content. They were subsequently offered a choice between the blue and yellow feeders in an unrewarded test. The bees preferred pure sucrose solutions over sucrose solutions with quinine, amino acids, or fatty acids, but not over solutions with salt. Our findings indicate that <i>T. fulviventris</i> is able to differentiate various nutrients in nectar and prefers pure sucrose solution or sucrose solutions with salt. Sugar and salt may therefore represent important nutrients in nectar and are likely key cues to assess nectar quality in tropical stingless bees.
