Sitompul F, Siregar EH, Roesma DI, Dahelmi, Prasetya E. 2018. Molecular identification of coffee (Coffea arabica) pollinator insects in North Sumatra, Indonesia based on designed COI primers. Biodiversitas 19: 1877-1883. Coffee (Coffea arabica L.) is one of the most important economic commodities in the province of North Sumatra, Indonesia. Insects associated with pollination of C. arabica are one of the key factors for successful cultivation of C. arabica, but, the research regarding of these was still limited. The population of coffee plant is scattered across the highlands of Indonesia and the pollination of C. arabica is strongly believed linked to a diverse group of pollinating insects. However, lack of taxonomic identification of insects pollinating these plants has become one of constraints to succeed the cultivation of C. Arabica. This study aimed to analyze types and variations of pollinating insects of C. arabica in the province of North Sumatra, Indonesia, using DNA barcoding. DNA barcoding is now considered an alternative method of molecular identification. Sixteen of C. arabica flower visitors were captured in different planting location in North Sumatra province. Using mtDNA markers, the cytochrome oxidase subunit sequence I (COI), about 12 pollinator insect species were identified based on the COI sequence i.e Amegilla cingulata, Apis dorsata, Apis cerana, Trigona chanchamayoensis, Idiella divisa, Dolichopodidae sp., Allactoneura sp., Stomorhina discolor, Phytomia erratica, Rhiniidae sp., Melipona bicolor, and Hymenoptera sp.

Bumblebees are commercially used to improve fruit set of greenhouse tomatoes, but they seldom pollinate tomatoes outdoors if not confined in a no-choice situation. Bumblebees frequently pollinated L. peruvianum and other self-incompatible (SI) Lycopersicon species, but not tomato plants, in the field at Geneva, N.Y. Bumblebees were very efficient pollinators of Sl Lycopersicon species, averaging only 5 s to pollinate one flower and fly to the next. Transfer of this attractiveness to pollinating insects to the tomato could improve fruit set of tomatoes grown in greenhouses with introduced bumblebees. It could also improve fruit set in the field, especially when conditions are poor for pollination. It has potential use for producing F1 hybrid seed, but associated problems make hybrid tomato seed production by insect pollination impractical now. Attractiveness to pollinating insects is being introgressed from L. peruvianum, L. hirsutum, and L. pennellii in the tomato breeding program at Geneva, N.Y. Several floral characteristics were found to be of importance for attracting pollinators, including the reaction to ultraviolet light. Flowers of SI species absorbed UV, whereas tomato flowers reflected UV light.

Abstract In 2004 and 2006-2008, a study was conducted on the effect of pollinating insects on the fruit, seed set, and development of two cultivars of blue honeysuckle Lonicera caerulea (Sevast.) Pojark.: "Atut" and "Duet". The experiment was carried out in south-eastern Poland, at the Experimental Farm of the University of Life Sciences in Lublin, Poland. Flowers accessible to pollinating insects throughout the whole flowering period, set fruit at a very high percentage. The study average was 90.57% for "Duet" and 88.08% for "Atut". During self-pollination under isolation, on the other hand, the percentage of fruit-bearing flowers was low. In the case of "Atut" the average was 9.37%, whereas for "Duet" it was 23.85%. Multiple fruits formed from isolated flowers had a 45-50% lower weight, on average, than those developed from flowers accessible to pollinating insects. The pollination mode was found to have a significant effect on the number of seeds produced in the multiple fruit. Flowers which were isolated to prevent insect foraging did develop multiple fruits, characterized by a significantly lower number of seeds. The recent studies confirm that several cultivars should be planted on honeysuckle acreage. The presence of managed pollinators can increase quantity and improve quality of fruit yield in honeysuckle.

Although canola, (Brassica napus L.), is considered a self-pollinating crop, researchers have indicated that crop productivity increases as a result of honey bee Apis mellifera L. pollination. Given this crop's growing importance in Rio Grande do Sul State, Brazil, this work evaluated the increase in pod and seed productivity with respect to interactions with anthophilous insects and manual pollination tests. The visiting frequency of A. mellifera was correlated with the crop's blooming progression, and productivity comparisons were made between plants visited by insects, manually pollinated plants (geitonogamy and xenogamy) and plants without pollination induction. Pod set and seed production per plant were determined for each treatment. Among the 8,624 recorded flower-visiting insects, Hymenoptera representatives were the most prevalent (92.3%), among which 99.8% were A. mellifera. The correlation between these bees and blooming progression was positive (r = 0.87; p = 0.002). Pollination induction increased seed productivity from 28.4% (autogamy) to 50.4% with insect visitations, as well as to 48.7 (geitonogamy) and to 55.1% (xenogamy) through manual pollination.

The production of fruits and seeds of many crops is increased when bees visit their flowers pollinating them. The aim of this research was to study the pollination of pumpkins (Cucurbita maxima Duch. var. Exposição), to determine the diversity of insects visiting its flowers, the time and type of provision obtained and the effect of the visits on fruit set, fruit size and weight, and number of seeds. Apis mellifera L. accounted for 73.4% of the visits made by bees, collecting pollen during 34.5 s per flower and nectar in 43.9 s and 29.3 s from female and male flowers, respectively. Trigona spinipes (Fabr.) collected only nectar, during a mean time of 60.5 s per flower, and represented 26.6% of the visits by bees. Diabrotica speciosa (Germ.) only fed on the petals of the flower. When no insect visits occurred, there was no production of fruits. In the flowers with free visitation by insects, fruit set was 40%. The higher the number of visits, up to 16, by A. mellifera to female flowers, the greater was the fruit set, fruit size and weight, and number of seeds. In flowers visited by insects from the onset of anthesis until 9 a.m., fruit set was 35%. After 9 a.m., there was no fruit set, demonstrating the important role of A. mellifera as a pollinating agent of pumpkin, since it was the only insect visiting up to 9 a.m.

Pollinator insects are insects that play a role in pollination, namely intermediaries pollinating plants. The purpose of this study was to determine the abundance and diversity of insects pollinators in the Cucumber (Cucumis sativus L) Plantation of Waiheru Village, Baguala District, Ambon City. Sampling was done by purposive sampling using a yellow glue trap (Yellow sticky trap). The customer observations are made in visual control. Observation starts at 07.00 WIT until 18.00 WIT which is divided into 3 time periods, namely: 07.00-10.00 WIT, 11.00-14.00 WIT and 15.00-18.00 WIT. The data obtained were analyzed using the diversity index (H ') according to Shannon and Wiener. The results showed that the total abundance of pollinator insects in vegetable plantations was 1220 individuals, consisting of 3 orders and 5 families. Insect families that play a role in the process of pollination are Family Apidae, Formicidae, Syrpidae, Muscidae and Papilionidae. The highest abundance of insects is dominated by the Formicidae Family while the lowest abundance is the Papilionidae Family. Value insect pollinator diversity found among the sites that H '= 1.21 which indicates that the level of diversity of insect pollinators on plantations Cucumber (Cucumis sativus L) in the Waiheru Village, Baguala District, Ambon City in the medium category.

Annotation:

The pollination requirements of strawberries (Fragaria x ananassa Duchesne cv. Tioga) were examined in a planting in southern Victoria. Plots that were accessible to honeybees (Apis mellifera L.) had 20.8% marketable berries (well shaped, > 10 g fresh weight), whereas plots that were not accessible had only 4.5% marketable berries. The total numbers of fruit (marketable and unmarketable) were not affected by the presence of pollinating insects. Honeybees were considered to be the main pollinators of this crop. They comprised 58.9% of insect visitors to the flowers. The behaviour patterns of other insects were such that they would effect little or no pollination. We conclude that the presence of an adequate population of honeybees increases the proportion of well shaped (marketable) berries.

Abstract:Nocturnally foraging insects may be supplementary pollinators to chiropterophilous plant species when bats are scarce. Given that insects are much smaller than bats, they may be more effective at transferring pollen for plant species with similar stamen and pistil lengths, such as the ‘Monthong’ durian cultivar. The present study clarifies the role of insects in pollinating the ‘Monthong’ cultivar by examining the floral biology, conducting pollination treatments on 19 trees and observing floral visitors in southern Thailand. Stigmas were receptive by 17h00, and over 50% of ‘Monthong’ anthers had dehisced by 17h30. Several bee species began foraging on flowers during the late afternoon, and the giant honey bee (Apis dorsata) continued to visit throughout the night. Our results show that at 4 wk after pollination, the highest fruit set occurred from hand-crossed pollination (13.5%), followed by open pollination (5.5%), insect pollination (3.3%) and automatic autogamy (2.0%), indicating that this cultivar is highly self-incompatible. Moreover, insects appear to be important pollinators of ‘Monthong’ durian in areas where nectar bats visit infrequently. One bee species in particular,Apis dorsata, commonly foraged on flowers at dusk and appears to be the most effective insect pollinator of durian. Our findings highlight that nocturnally foraging bees are capable of securing pollination for night-blooming plant taxa, even those typically considered to be bat-pollinated.

Abstract:Floral morphology often directly influences interactions with pollinators, but less is known about the role of extrafloral structures. We studied the relationship between bract motility, floral structural specialization and pollination in Dalechampia aff. bernieri, an endemic Madagascan species with floral structures indicating specialized buzz-pollination. We measured circadian bract angles in 47 inflorescences from 11 plants of D. aff. bernieri; in addition, we recorded any flower-visiting insects observed. The inflorescences had motile bracts with mean angles varying from ~50° at 00h00 to ~90° at 10h45. They were visited by buzz-pollinating Nomia viridilimbata bees (Halictidae), but also by non-buzz-pollinating Liotrigona bees (Apidae). The temporal pattern of bract motility observed in D. aff. bernieri may represent an extra-floral specialization to reduce visitation by non-pollinating visitors while maximizing visitation by diurnal buzz-pollinating bees.

Perhaps the most conspicuous of associations between insects and plants is pollination. Pollinating insects are typically the first and most obvious of interactions between insects and plants when one encounters a montane meadow or a tropical woodland. The complex ecological structure of insect pollinators and their host plants is a central focus within the ever-expanding discipline of plant-insect interactions. The relationships between plants and insects have provided the empirical documentation of many case-studies that have resulted in the formulation of biological principles and construction of theoretical models, such as the role of foraging strategy on optimal plant-resource use, the advantages of specialized versus generalized host preferences as viable feeding strategies, and whether “pollination syndromes” are meaningful descriptions that relate flower type to insect mouthpart structure and behavior (Roubik, 1989; Ollerton, 1996; Waser et al., 1996; Johnson and Steiner, 2000). Much of the recent extensive discussion of plant-insect associations has centered on understanding the origin, maintenance, and evolutionary change in plant/pollinator associations at ecological time scales and increasingly at longer-term macroevolutionary time intervals (Armbruster, 1992; Pellmyr and Leebens-Mack, 1999). Such classical plant-insect association studies—cycads and cycad weevils, figs and fig wasps, and yuccas and yucca moths—were explored at modern time scales and currently are being examined through a long-term geologic component that involves colonization models based on cladogenetic events of plant and insect associates, buttressed by the fossil record (Farrell, 1998; Pellmyr and Leebens-Mack, 1999; A. Herre,pers. comm.). In addition to tracing modern pollination to the earlier Cenozoic and later Mesozoic, there is a resurgence in understanding the evolutionary history of earlier palynivore taxa (spore, prepollen and pollen consumers), which led toward pollination as a mutualism (Scott et al., 1992).

The risks posed by rapidly evolving RNA viruses to human and animal health are well recognized. Epidemics in managed and wildlife populations can lead to considerable economic and biodiversity losses. Yet, we lack understanding of the ecological and evolutionary factors that promote disease emergence. Host-switching viruses may be a particular threat to species important for human welfare, such as pollinating bees. Both honeybees and wild bumblebees have faced sharp declines in the last decades, with high winter mortality seen in honeybees. Infectious and emerging diseases are considered one of the key drivers of declines, acting in synergy with habitat loss and pesticide use. Here I focus on multihost viruses that pose a risk to wild bumblebees. I first identify the risk factors driving viral spillover and emergence from managed honeybees to wild bumblebees, by synthesising current data and literature. Biological factors (i.e. the nature of RNA viruses and ecology of social bees) play a clear role in increasing the risk of disease emergence, but anthropogenic factors (trade and transportation of commercial honeybees and bumblebees) creates the greatest risk of viral spillover to wild bees. Basic knowledge of the pathogenic effect of many common pollinator viruses on hosts other than A. mellifera is currently lacking, yet vital for understanding the wider impacts of infection at a population level. Here, I provide evidence that a common bumblebee virus, Slow bee paralysis virus (SBPV), reduces the longevity of Bombus terrestris under conditions of nutrition stress. The invasion of Varroa destructor as an ectoparasitic viral vector in European honeybees has dramatically altered viral dynamics in honeybees. I test how this specialist honeybee vector affects multi-host pathogens that can infect and be transmitted by both honeybees and wild bumblebees. I sampled across three host species (A. mellifera, B. terrestris and B. pascuorum) from Varroa-free and Varroa-present locations. Using a combination of molecular and phylogenetic techniques I find that this specialist honeybee vector increases the prevalence of four multi-host viruses (deformed wing virus (type A and B), SBPV and black queen cell virus) in sympatric wild bumblebees. Furthermore, wild bumblebees are currently experiencing a DWV epidemic driven by the presence of virus-vectoring Varroa in A. mellifera. Overall this thesis demonstrates that wild bumblebees are at high risk of viral disease emergence. My research adds to the ever-expanding body of evidence indicating that stronger disease controls on commercial bee operations are crucial to protect our wild bumblebees.

Annotation:

Insect mediated pollen dispersal was studied in Althaea officinalis, Succisa pratensis, Chrysanthemum coronarium, Matricaria maritima and Matthiola sinuata using fluorescent dust as a pollen analogue or tracer. The species where chosen because of their different spectra of pollinators, so that the effects on pollen transfer of different behaviour patterns in different insect groups could be assessed. Pollinator behaviour was also studied by direct observation of insects foraging in both natural and artificial plant populations. Individual pollinators were marked in many cases, and both general behaviour patterns, and differences between individuals were studied. Evidence is presented to indicate that foraging insects generally move into the wind, and that pollen flow is therefore generally upwind. Also, most pollen transfers occur within a range of ten metres or often considerably less, although occasional movements to much greater distances are recorded. The behaviour patterns of various insect groups are discussed, with particular emphasis on comparing and contrasting bumblebees, butterflies, moths and hoverflies in terms of constancy, directionality and distance of flight. While many generalisations can be made, it becomes clear that it is also very important to understand that individuality can be significant. Thus, different individuals within a species can often exhibit a degree of constancy or discrimination. In some species this may result in discrimination by the population as a whole, while others may have a homogeneous overall behaviour pattern.

Habitat restoration is an important tool in reducing the current decline in biodiversity. To determine the success of restoration, ecologists have previously focused on species richness or on the presence of rare species; little is known of species interactions. This study examines both the potential of restored landfill sites to support pollinating insects and how flower-insect interactions can be used in determining successful restoration. These are important attributes of ecosystem function. Standard belt transects were used to record flowering insect pollinated plants and flower-visiting insects on nine paired restored landfill and reference nature sites, in the broader Northamptonshire region (UK). Over the duration of this study, an area of 25,000m2 was surveyed for floral characteristics and approximately 138,000 floral units were counted from 98 plant species. A total of 201 flower visitor surveys were performed, with 942 flower-visiting insect samples taken. Flowering plant species richness and abundance of floral resources on restored landfill sites were not found to be significantly different from those on reference sites and the flower-visiting insect assemblages were similar in terms of species-richness and abundance. Interaction structures were examined and whilst the plant-insect assemblages had few species in common, both showed similar levels of nestedness and connectance. The differences in the species but similarity in the functioning of these assemblages emphasise the importance of examining interaction structures within a functional approach to the evaluation of restoration. There are 2,200 landfill sites in England and Wales covering some 28,000 ha, and this study highlights that their restoration can potentially provide an important resource for the conservation of pollinating insects and the services that they provide for both natural and agricultural plants.

Annotation:

The superfamily Apoidea (commonly referred to as bees), are insects whose diet consists of the nectar and pollen from flowering plants. Therefore, they are essential pollinators of many species, both wild and cultivated. Bees are similar to other Hymenoptera in appearance, size, and color variety. The superfamily Apoidea contains 17,000 known species and could possibly contain up to 30,000. Bees perform many tasks that benefit humanity such as pollinating the flowers of both wild and cultivated plants. Without this work, fruits and seeds necessary for the survival of different species, for our own food supply, and for industry would not be able to be produced. The study was done in three communities in the Yungas (Carmen Pampa, San Pablo, and San Juan de la Miel). In each community, three Malaise traps were introduced in three ecological ni ches (Forest, Forest Edge, and Crop Area). Each collection was done every 14 days throughout the six months of winter and spring. The quantification and identification of the Apoidea was conducted in a laboratory through identification keys for families, genera, and species. In total, 83 different morphospecies were identified. In the three communities, a total of 1117 individuals were recorded during the six months of field work. With regard to the niche factor, Partamona sp. (sp2) and Apis mellifera (sp1) were those species that contributed most to the abundance of individuals. In addition, both species contributed to the similarity and dissimilarity seen in the three ecological niches of the three communities. This indicates that they are the most abundant groups within the Yungas forests. They nest primarily in wood, are highly general, are highly social, and are present throughout the year. It is also worth mentioning that the community and station factors do not contribute to the differences in species diversity. Based on the results of this research, a new phase was initiated to identify the species contained within the 83 morphospecies found in the Yungas of La Paz.

Composition of pollen pellets foraged by honeybees, sampled in Degernäs and Tavelsjö, Västerbotten County, during early summer 2020, is used to explore if honeybees are monofloral or polyfloral. Samples from different days and different colours were evaluated by light microscopy. Each unique pollen species in each pellet was morphologically identified with help of an international pollen database (PalDat) and a common bee plant document, using light microscopy and scanning electron microscope photographs. A selection of pollen species were identified down to species level and were used to explore which wild pollinators can also pollinate these plant species, to speculate around possible competition scenarios between them and honeybees. SEM and DNA extraction were performed with a selection of the pollen pellets and with the extracted DNA, different PCR primers targeting different plant gene markers were tested to see which ones worked with pollen from northern Sweden. More detailed pictures of the pollen grains were seen in SEM which helped ease the species identification of some of them. The results showed that only a few of the pollen pellets had only one detected plant species while the rest had 2 or more plant species in them. Thus, these data indicate that the honeybees in Degernäs and Tavelsjö are polyfloral, at least for the samples studied in this bachelor thesis. Methods are evaluated and the findings were that a combination of morphological and molecular biology studies are both needed to be able to establish a new updated pollen database for northern Sweden.

Com o objetivo de conhecer a composição dos insetos e das plantas visitadas nas áreas de cerradão e cerrado sensu stricto, da Estação Experimental de Itirapina, SP, foram realizadas amostragens sistemáticas dos insetos nas plantas, no período de março de 2003 a fevereiro de 2004. Do total de insetos coletados nas flores, 63,3% e 63,8% são da ordem Hymenoptera, 17,1% e 2,5% da ordem Lepidoptera, 16% e 19,5% da ordem Coleoptera e 3,6% e 12,8% da ordem Diptera, respectivamente, para as áreas de cerradão e cerrado sensu stricto, e 1,4% para Hemiptera-Heteroptera no cerrado sensu stricto. A maioria dos insetos coletados, visitando e/ou forrageando, nas duas áreas, foi no período da manhã, exceto os dípteros que preferiram o período da tarde. Na área de cerradão as espécies dominantes de Hymenoptera foram: Exomalopsis (Exomalopsis) sp. e Trigona spinipes; de Lepidoptera foram: Aeria olena e Ithomia agnosia; de Coleoptera foram: Nycterodina sp. e Spintherophyta sp.. Já na área de cerrado sensu stricto os hymenópteros dominantes foram: Apis mellifera, Exomalopsis cf. analis, Tetrapedia rugulosa, Trigona spinipes e Pepsis sp., para Coleoptera foram: Spintherophyta sp., Compsus sp. e Epitragus similis; para Diptera foram: Eristalis sp. e Ornidia obesa. A família Apidae foi a mais rica em espécies e abundância, nas duas áreas de cerrado, seguindo o padrão geral encontrado em outras áreas neotropicais até o momento estudadas, apresentando muitas espécies com poucos indivíduos e poucas espécies com muitos indivíduos. Quanto a composição da flora, em ordem decrescente, as famílias Asteraceae, Melastomataceae, Apocynaceae, Malpighiaceae e Rubiaceae foram as mais representativas na área de cerradão. Na área de cerrado sensu stricto as famílias com maior número de espécies foram Fabaceae, Malpighiaceae, Asteraceae, Bignoniaceae e Myrtaceae. As espécies vegetais com maior percentual de insetos visitantes na área de cerradão foram Diplosodon virgatus (Lythraceae), Daphnopsis racemosa (Thymelaeaceae) e Borreria verticillata (Rubiaceae), e no cerrado sensu stricto foram Ocotea pulchella (Lauraceae) e Miconia rubiginosa (Melastomataceae). A família Apidae foi a que visitou maior número de espécies botânicas, seguida por Nymphalidae, Chrysomelidae, Halictidae e Vespidae, na área de cerradão. No cerrado sensu stricto foram Apidae, Syrphidae, Chrysomelidae, Curculionidae, Halictidae, Vespidae e Pompilidae. Dos insetos dominantes, Apis mellifera foi a que visitou o maior número de espécies de plantas, seguida de Exomalopsis (Exomalopsis) sp., Aeria olena e Trigona spinipes, no cerradão; e no cerrado sensu stricto foram Apis mellifera, Trigona spinipes, Exomalopsis cf. analis e Tetrapedia rugulosa.

Considering all insects collected on flowers in the cerradao and cerrado areas stricto sensus , 63.3% and 63.8% were Hymenoptera, 17.1% and 2.5% were Lepidoptera, 16.0% and 19.5% were Coleoptera and 3.6% and 12.8% were Diptera, respectively, while in the cerrado stricto sensus 1.4% were Hemiptera-Heteroptera. Most insects collected were visiting and/or foraging in the areas during the morning, except for diptera, which preferred the afternoon period. The dominant species within each order in the cerradao area were: Hymenoptera - Apis mellifera, Exomalopsis (Exomalopsis) sp. and Trigona spinipes; Lepidoptera - Aeria olena and Ithomia agnosia; Coleoptera - Nycterodina sp. and Spintherophyta sp.. In the cerrado area stricto sensus the dominant species were: Hymenoptera - Apis mellifera, Exomalopsis cf. analis, Tetrapedia rugulosa, Trigona spinipes and Pepsis sp.; Coleoptera - Spintherophyta sp., Compsus sp. and Epitragus similis; Diptera - Eristalis sp. and Ornidia obesa. The Apidae Family was the richest in species and most abundant in both cerrado areas, following the general pattern of other Neotropical areas already studied, with many species with few individuals and few species with many individuals. Regarding the floristic composition, the most representative families in the cerradao area were, in order, Asteraceae, Melastomataceae, Apocynaceae, Malpighiaceae and Rubiaceae. Families with most species in the cerrado area stricto sensus were Fabaceae, Malpighiaceae, Asteraceae, Bignoniaceae and Myrtaceae. The plant species in the cerradao area with the greatest percentage of visiting insects were Diplosodon virgatus (Lythraceae), Daphnopsis racemosa (Thymelaeaceae) and Borreria verticillata (Rubiaceae), while in the cerrado stricto sensus they were Ocotea pulchella (Lauraceae) and Miconia rubiginosa (Melastomataceae). The Apidae family was the one visiting most plant species in the cerradao area, followed by Nymphalidae, Chrysomelidae, Halictidae and Vespidae families, while in the cerrado stricto sensus the families visiting most plant species were Apidae, Syrphidae, Chrysomelidae, Curculionidae, Halictidae, Vespidae and Pompilidae. Apis mellifera was the species among the dominant insects of the cerradao area which visited the greatest number of plant species, followed by Exomalopsis (Exomalopsis) sp., Aeria olena and Trigona spinipes. In the cerrado stricto sensus the insect species that visited the greatest number of plants were Apis mellifera, Trigona spinipes, Exomalopsis cf. analis and Tetrapedia rugulosa.

Annotation:

For over twenty years, flower-visitation networks have been used to assess the effects of pollinator decline, linked to habitat loss, climate change and invasive species, on entire communities. However, most rely on flower visit frequency as a proxy for pollination; very few sample pollen from flower visitor's bodies or from stigmas and so do not include a quantitative measure of pollination success. Here, I add pollinator effectiveness (as single visit pollen deposition) into a traditional flower visitation network, creating a pollinator importance network that better evaluates the flower visitor community from the plant's perspective. Given recent interest in pollination in urban areas, I use an urban garden habitat, and compare visitation, pollen transport and pollinator importance networks, giving several novel conclusions. Firstly, although there are similarities in the structure of my networks, interactions were most specialised in the pollinator importance network, with pollen transport proving to be a better proxy for pollinator importance than visitation alone. Secondly, the specialisation of individual plants and the role of individual flower visitors varied between the networks, suggesting that community-level patterns in simple visitation networks can mask important individual differences. Thirdly, the correlation between flower visit frequency and pollinator importance largely depends on bees, and may not hold in plant-pollinator communities that are not bee-dominated. Fourthly, heterospecific pollen deposition was relatively low, despite the unusually diverse plant community of a garden. Finally, bees (particularly Bombus and non-eusocial halictids) carried the largest pollen loads and were the most effective at depositing pollen on to the stigma during a single visit in this garden habitat. The implications of this thesis highlight the strengths and limitations of each network for future studies, and raise important questions for the future of urban pollination studies.

Abstract In this chapter the future of garden tourism is examined. Botanic gardens have multiple roles but principally education, environmental, and recreation, and it is under these three roles that garden tourism's future is evaluated. Case studies are presented of (1) the National Botanic Garden of Wales as a floral resource for pollinating insects; and (2) the high school botany teaching program of the Fairchild Tropical Botanic Garden in Coral Gables, Florida, USA.

Common sunflower is an entomophilous crop; therefore, the presence of pollinating insects is necessary for the realization of the potential productivity of plants. Nectar is the main attractant of sunflower. In this work we determined the nectar bearing capacity and sugar content (dry matter content) of nectar in tubular flowers of various sunflower genotypes using microcapillary tubes with an inner diameter of 0.25 mm and an outside diameter of 0.50 mm. We noted the maximum amount of nectar in a line of genetic collection MVG-8 – 0.32 mg/flower. We observed the maximum value of sugar content in hybrids NK Brio and Factor – 61 and 57 %, respectively. The Oksi hybrid had the minimum values in the amount of 0.11 mg/flower and 21 % of the nectar sugar content.
