Among insects, bees are the main pollinators of most Angiosperm species. The aim of this paper was to study the effect of bee body size on the pollination of Cucurbita maxima Duch. (Cucurbitaceae) var. zapallito crops. We quantified stigmatic pollen deposition by single visits of bee species with different body sizes. Bee species were classified into four categories accordingly to their intertegular distance: Very small (≤ 1.7 mm), Small (1.71 mm < 2.7 mm), Medium (2.71 mm < 3.7 mm) and Large (> 3.71 mm). Fifteen bee species belonging to the Apidae and Halictidae families were observed depositing pollen on the stigmas of C. maxima. The number of pollen grains deposited and the probability of pollen deposition per visit increased significantly with body size. Large bees Xylocopa augusti and Bombus pauloensis were the most efficient species at depositing pollen on stigmas followed by medium-sized bees Eucera fervens and Apis mellifera. The results show that several wild bee species play an important role in the pollination of C. maxima crops.

In order to document pollen and nectar resources for M. beecheii during the dry season, 25 pot-pollen and 25 pot-honey samples were collected from February to May 2021 at eight villages in Yucatan, Mexico. All samples were acetolysed, and 500 pollen grains were counted randomly for each sample. A total of 21 taxa belonging to eight botanical families were observed in the pot-pollen samples; in contrast, 32 pollen types from 16 botanical families were recorded in the pot-honey samples. According to PCA analyses, the pollen types that explained the maximum variance among the pot-pollen samples were Senna racemosa var. racemosa, Lonchocarpus punctatum, Cochlospermum vitifolium, Bursera schlechtendalii and B. simaruba, while S. racemosa var. racemosa, C. vitifolium, Alternanthera ramosissima, Psidium guajava, B. schlechtendalii, B. simaruba, L. punctatum, Mimosa bahamensis and Solanum americanum explained the greatest variance among the pot-honey samples. Our results confirm that M. beecheii displays polylectic foraging and targets for the secondary vegetation of tropical deciduous and tropical semideciduous forests. Diversity in the pot-pollen was found to be lower than that of the pot-honey samples.

In this study, we evaluated pollinators’ contribution to two self-fertile almond varieties (Marta and Marinada) and the density of pollinators needed to ensure adequate pollination. We measured the effects of pollinators on fruit set, seed yield, and pollination limitation at the tree level. Managed honeybees and wild bumblebees were the main floral visitors in both varieties. Both fruit set and seed yield were ~ 50% higher in pollinated trees than in excluded ones in the two varieties.

Mixed mesepisternum color on some bees has raised discussions about the taxonomic status of these species if some degree of hybridization can occur between them and they should be regarded as subspecies. Our goal was to investigate if T. angustula and T. fiebrigi are two valid species and contribute to their taxonomic identification. We sampled several colonies from distant Brazilian regions (range of 3,000 km) to analyze the mesepisternum color variation of males and workers, genitalia morphology of males and females (queens and workers), and aggressiveness of the workers in both species. Despite some color variations in some colonies, there are always individuals with typical mesepisternum color inside each colony, i.e., black in T. angustula and ferruginous in T. fiebrigi. The fact that both T. angustula and T. fiebrigi males have black mesepisternum could be causing species misclassifications. The genitalia morphology of males (shape and length of gonostylus and penis valve) and females (gonostylus shape) was consistently different between both species. None of the analyzed male aggregations exhibited mixed males of T. angustula and T. fiebrigi, which indicates that the queen attracts only co-specific males. Tetragonisca angustula workers displayed an aggressive behavior, whereas T. fiebrigi workers were unaggressive. The observed morphological and behavioral differences may be indicators of reproductive isolation between the two species. Therefore, we conclude that T. angustula and T. fiebrigi are two valid species.</div>","PeriodicalId":8078,"journal":{"name":"Apidologie","volume":"55 2","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140016922","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}

Females of both species were obtained from field collections and museums, representing a large part of their morphotype distribution. Additional diagnostic characters of the external morphology were investigated, such as metasomal band colour, metasomal punctuation, wing colours, and apical regions of the basitibial plate. Mitochondrial gene sequences (COI and CytB) were used for phylogenetic reconstructions. Our results showed that both nigrocincta and suspecta morphotypes are undistinguished based on morphology, although the metasomal band colour, together with the geographic distribution, revealed the presence of three distinct morphogroups, including an intermediate one with a variable number of reddish bands. Nonetheless, the three morphogroups are not supported by molecular data and therefore represent intra-specific variations.

Flowering plant species richness had a positive effect on bee species richness in one study year. Though we recorded more bee species in SNHs than meadows, overall and specifically in ecologically specialized bee species (e.g. parasitic bees, oligoleges), the availability of adjacent SNHs did not affect bee abundance and richness in meadows.
