“…We found that long tongued bees like Eucera, Anthophora, and Amegilla were more abundant at Fabaceae flowers that are characterized by flowers with a deep corolla tube (Aouar-sadli et al, 2008;Shebl and Farag, 2015;Marzinzig et al, 2018). Likewise, Solanaceae crops that typically require buzz pollination for fertilization were found to be visited mostly by X. pubescens and A. quadrifaciata, the two species which represent groups of efficient buzz pollinators (Gemmill-herren and Ochieng, 2008;Jayasinghe et al, 2017;Toni et al, 2020;Udayakumar et al, 2021).…”

“…A recent study comparing the effect of reduction of fertilizer input, irrigation, and pollination, found that a reduction of insect pollination has a stronger effect on crop yield than other agricultural inputs (Fijen et al, 2020). Furthermore, insect pollination enhances the yield and the quality of many crops at both the local and global scale, such as for faba bean (Aouarsadli et al, 2008;Cunningham and Le Feuvre, 2013), strawberries (Abrol et al, 2019;MacInnis and Forrest, 2019), apple (Garratt et al, 2014a;Hünicken et al, 2021), eggplant (Jayasinghe et al, 2017), cucumber (Christmann et al, 2017(Christmann et al, , 2022, and tomato (Bashir et al, 2018;Toni et al, 2020). Moreover, many countries are becoming increasingly dependent on pollinators because production has shifted to more pollinator-dependent crops (Aizen et al, 2008;Potts et al, 2016).…”

Agroecosystems are often impoverished ecosystems, but they can host diverse communities of insects which provide ecosystem services. Specifically, crops may benefit from insect pollinators that increase their quantity and quality of yields. Basic knowledge is still needed regarding the identity, diversity, abundance, and ecology of insect pollinators in many parts of the world, especially in low and middle-income countries. In this study we investigate the potential of agroecosystems and crops in Morocco to host a high diversity of insect pollinators. We sampled insects in four eco-climatic regions encompassing a total of 22 crops for 2 years (2018–2019). After describing the general pattern of diversity and abundance of insect pollinators, we focused our comparative analyses on bees as they are known to be the most efficient and abundant group of insect pollinators. We recorded a total of 53,361 insect pollinators in all agroecosystems among which 37,091 were visiting crop flowers. Bees were by far the most abundant group visiting crops. Honeybees represented 49% of crop visitors followed by wild bees representing 33% of relative abundance. Three genera (Lasioglossum, Andrena, and Xylocopa) represented 53% of the total abundance of wild bees visiting crops. We identified a total of 213 species visiting crops (22% of national wild bee species richness). A comparison of the abundance, species richness, and community composition of wild bees visiting the same crops showed significant inter-regional differences for zucchini, faba bean, and eggplant. This study highlights the high diversity of pollinators in Moroccan agroecosystems and represents an important step toward exploring the Moroccan pollinator fauna. It provides basic information for future studies on pollinator conservation and pollination services.

“…They also checked fruit sets 15 days after pollination, by observing pollen tube growth in pistils and estimating pollination quality through the percentage of ovules penetrated by pollen tubes. In another study, the total number of fruits and seeds and eggplant weight and length were indirect measures of the success of wild bee visits [68]. These authors also investigated the relationship between handling time in flowers of different ages (newly open, 1 day old, 2 days old, more than 2 days old) and the number of pollen grains remaining on the anther.…”

“…All have been widely used in recent decades. Walking transect ranges span from 100 × 1 m trails to be covered in 20 min [68], to 200 × 1 m in 20 min [76], and 250 × 4 m in 50 min [59]. Walking transects are usually defined as variable [31,76,77] when the position and direction of a transect are chosen randomly during the sampling, or standard-fixed when the same spot is visited in subsequent monitoring periods.…”

The pollination ecology in agroecosystems tackles a landscape in which plants and pollinators need to adjust, or be adjusted, to human intervention. A valid, widely applied approach is to regard pollination as a link between specific plants and their pollinators. However, recent evidence has added landscape features for a wider ecological perspective. Are we going in the right direction? Are existing methods providing pollinator monitoring tools suitable for understanding agroecosystems? In Italy, we needed to address these questions to respond to government pressure to implement pollinator monitoring in agroecosystems. We therefore surveyed the literature, grouped methods and findings, and evaluated approaches. We selected studies that may contain directions and tools directly linked to pollinators and agroecosystems. Our analysis revealed four main paths that must come together at some point: (i) the research question perspective, (ii) the advances of landscape analysis, (iii) the role of vegetation, and (iv) the gaps in our knowledge of pollinators taxonomy and behavior. An important conclusion is that the pollinator scale is alarmingly disregarded. Debate continues about what features to include in pollinator monitoring and the appropriate level of detail: we suggest that the pollinator scale should be the main driver.

“…melongena Linnaeus, 1753), is a major crop in many countries whose pollination requirements remain poorly studied [ 26 , 27 ]. Eggplant flowers are hermaphroditic and, can be self-compatible [ 27 ], though heavier fruit and larger number of seeds can result from cross pollination by sonicating bees [ 28 , 29 ]. Mexico is a center of diversification of the genus Solanum and the country is one of the largest producers of Solanum crops in the Americas, including eggplant, with ca.…”

Pollination service provided by honey bees to buzz-pollinated crops in the Neotropics

et al. 2023

Generalist honey bees grant significant pollination services worldwide. Although honey bees can provide compensatory pollination services, their service to buzz-pollinated crops, compared to specialized pollinators, is not clear. In this study, we assessed the contribution of Africanized honey bees (AHB) and native sonicating bees (NBZ) to the pollination of eggplant (Solanum melongena) and annatto (Bixa orellana) in Yucatan, Mexico, one of the largest producers of these crops in the Americas and a region with one of the largest densities of honey bees in the world. We first compared the relative frequency and abundance of both bee types on flowers of both crops. Secondly, we controlled access to flowers to compare the number and weight of fruit and number of seed produced after single visits of AHB and native bees. For a better assessment of pollination services, we evaluated the productivity of individual flowers multiply visited by AHB. The results were compared against treatments using pollinator-excluded flowers and flowers that were supplied with additional pollen, which allowed an overall measure of pollination service provision (PSP). Our results showed that AHB were the predominant flower visitors in both crops and that were poorly efficient on individual visits. Notably, fruit quantity and seed number increased concomitantly with the number of AHB visits per flower on eggplant, but not on annatto. Estimation of PSP revealed no pollination deficit on eggplant but that a deficit existed on the pollination services to annatto. We found that AHB numerical predominance compensates their poor individual performance and can complement the services of native bees on eggplant, but not on annatto. We discuss possible explanations and implications of these results for buzz-pollinated crops in the neotropics an area with little assessment of pollination services and a high density of honey bees.
