The Relationship

To better understand the relationship between Spondias mombin (Anacardiaceae) with its floral visitors, we investigated stigma receptivity and flowering pattern, as well as the abundance, frequency and behavior of bees visiting its flowers, aiming to discuss their potential as pollinator of this plant species. We studied S. mombin in an orchard in Northeastern Brazil. Stigma receptivity coincided with the time bees were foraging, mainly for pollen. According to the bee behavior on flowers, their visiting hour, abundance, and frequency in the studied area, we concluded that Apis mellifera (Linnaeus), Trigona spinipes (Fabricius), Xylocopa grisescens (Lepeletier) and Augochloropsis sp. are potential pollinators of S. mombin. Also, A. mellifera and T. spinipes were the most abundant species in the area and collected floral resources with greater frequency, contributing more significantly to pollination. Due to the overwhelmingly presence of these two bee species in NE Brazil, we conclude they are the main potential pollinators of S. mombin in the region.

Background and aims – Copaifera coriacea, a species in the resin-producing clade Detarioideae (Leguminosae), is an endemic and abundant species found in sand dunes in Brazilian Caatinga domain vegetation – a Quaternary paleodesert. We investigated floral traits and aspects of pollination biology, focusing on the pollination system of C. coriacea. Material and methods – Anthesis duration, stigma receptivity, pollen viability, nectar concentration, and the presence of osmophores and pigments reflecting UV light were assessed. Floral visitors were classified as potential pollinators, occasional pollinators or thieves, based on the time and foraging behaviour and resource collected. Pollination effectiveness were assessed for potential pollinators by the detection of pollen tubes on the stigma or stylar canal by epifluorescence microscopy.Key results – The species has white and small flowers, with anthesis beginning in the dark (ca 00:30) and the flowers are completely opened approximately 3 h later, when a sweet odour is perceptible. The onset of stigma receptivity and pollen grain viability occurs only after the completion of flower opening, and a concentrated nectar is available during the day. The presence of pollen tubes confirmed the efficiency of the main insects in the transfer of pollen. Conclusion – Our result demonstrates that C. coriacea has a generalist pollination system mediated mainly by two distinct guilds of insect pollinators: moths (nocturnal, searching for nectar) and bees (diurnal, pollen collectors). This finding can provide more information about diversification in the genus Copaifera.

Um fator indispensável na manutenção da produtividade agrícola é a polinização. Entre os vários agentes polinizadores, os insetos são considerados os principais agentes atuantes na polinização da maioria das culturas. O trabalho teve como objetivo compreender a estratégia reprodutiva de Cucurbita moschata Poir (Cucurbitaceae) a partir da análise dos métodos de polinização utilizados pela planta e do registro da diversidade e comportamento dos visitantes florais. Para avaliar a eficiência dos polinizadores, 10 flores de C. moschata foram etiquetadas para verificar a formação de frutos em condições naturais. Outras 10 flores foram envolvidas em sacos impermeáveis para impedir o contato com os insetos visitantes. Os insetos foram coletados diretamente nas flores, das 7:00 h às 11:15 h, durante 15 minutos de cada hora, anotando-se os valores de temperatura, luminosidade, umidade relativa do ar e velocidade do vento. O sucesso reprodutivo de C. moschata depende de polinizadores, uma vez que o isolamento reprodutivo das flores não permitiu a formação de fruto. A ordem mais abundante foi Diptera, seguida por Hymenoptera, Coleoptera, Hemiptera e Lepidoptera. Os polinizadores efetivos de C. moschata foram representados por espécies de abelhas de porte corporal grande: Apis mellifera Linnaeus, Centris sp., Oxaea flavescens Klug e Bombus sp. Essas espécies visitaram as flores para coletar néctar e pólen. Os fatores abióticos tiveram pouca influencia nas atividades de forrageio dos visitantes florais. Reproductive Strategy of Cucurbita moschata Poir (Cucurbitaceae) and Foraging Activities of their Floral Visitors Abstract. An essential factor in maintaining agricultural productivity is pollination. Among the various pollinators, the insects are considered the main active agents in pollination of most cultures. The work aimed to understand the reproductive strategy of Cucurbita moschata Poir (Cucurbitaceae) through analysis of the pollination methods used by the plant and the record of the diversity and behavior of floral visitors. To assess the efficiency of pollinators, 10 flowers of C. moschata were labeled to check the formation of fruit under natural conditions. Other 10 flowers were wrapped in waterproof bags to prevent contact with visiting insects. The insects were collected directly in the flowers, from 07:00 to 11:15 am, during 15 minutes of every hour, recording the values of temperature, luminosity, relative humidity and wind speed. The reproductive success of C. moschata depends on pollinators, since the reproductive isolation of the flowers did not allow the formation of fruit. The most abundant order was Diptera, followed by Hymenoptera, Coleoptera, Hemiptera and Lepidoptera. The effective pollinators of C. moschata were represented by species of bees of large body size: Apis mellifera Linnaeus, Centris sp., Oxaea flavescens Klug and Bombus sp. These species visited the flowers to collect nectar and pollen. The abiotic factors had little influence on foraging activities of floral visitors.

And Behavior

The study was carried out to verify if there are differences in foraging frequency and behavior of Apis mellifera in two melon hybrids (10:00 – ‘Yellow melon’ and Sancho -‘Piel de Sapo’) in the municipality of Juazeiro, state of Bahia, Brazil. The frequency, behavior of visitors and the floral resource foraged were registered from 5:00 am to 6:00 pm. There was a significant difference in the frequency of visits when comparing hydrids (F = 103.74, p <0.0001), floral type (F = 47.25, p <0.0001) and resource foraged (F = 239.14, p <0.0001). The flowers of Sancho were more attractive to A. mellifera when compared with hybrid 10:00, which may be correlated to the morphology and floral resources available. This could be solved with scaled planting, avoiding the overlapping of flowering of both types.

Considering the important roles of pollinators in ecosystem services, their identification and studies of their behavior would be extremely important to efforts directed towards their preservation and management. With the aim of examining the diversity and behavior of the floral visitors to Campomanesia adamantium (Cambessédes) O. Berg (“guavira”) and how they act in the pollination process, a total of 31 species belonging to the orders Hymenoptera (79.30 %), Coleoptera (11.34 %), Diptera (9.1 %), and Hemiptera (0.24 %) were identified. Among the Hymenoptera, africanized Apis mellifera, Brachygastra lecheguana, and Trachymyrmex sp. were considered dominant. Foraging was most intense between 07:00 and 10:00 h, with decreased activity after 13:00 h. The insects visited the plants in search of pollen and nectar, with pollen being the principal resource offered. Among the pollinators, africanized Apis mellifera stood out due to their behavior, frequency of visitation, abundance (being responsible for 53.24 % of all floral visits), and their constant presence on C. adamantium flowers during the entire observation period. Other insects (wasps, ants, and coleopterans) were associated with floral tissue predation.

Low Efficiency

Previous studies have shown the superior competitive ability of honeybees compared with native bees in the exploitation of floral resources and nesting sites besides their low efficiency in pollinating native plant species. However, there is little evidence of the effect of this invading species on autochthonous plant populations in natural environments. Thus experiments were performed to test the pollination efficiency of honeybees in two species of Jatropha (Euphorbiaceae), J. mollissima (Pohl) Baill. and J. mutabilis (Pohl) Baill., after a single flower visitation. Samplings were carried out between March and April 2006 in a hyperxerophilous shrub-arboreal Caatinga at Estação Biológica de Canudos, Bahia (9º 56´ 34" S, 38º 59´ 17" W), the property of Fundação Biodiversitas. Apis mellifera was efficient at pollinating J. mollissima (100%) and J. mutabilis (85%). This high efficiency may be explained by 1) the simple floral characteristics of both plant species, which facilitate access to the sexual organs of the plant; and 2) the body size of A. mellifera that fits the flower's dimensions.

As abelhas são os principais polinizadores de culturas agrícolas e plantas silvestres, mas pouco se sabe sobre sua eficiência na polinização de culturas tropicais. O presente trabalho objetivou investigar os visitantes florais e suas eficiências como polinizadores em relação aos requerimentos de polinização da cajazeira (Spondias mombin L.). O trabalho foi conduzido em Limoeiro do Norte, Ceará, e constou do levantamento dos visitantes florais e tratamentos de requerimentos e de eficiência de polinização. Os resultados mostraram que, apesar de sete espécies de abelhas terem visitado as flores da cajazeira e desta ser uma espécie com sistema misto de polinização, o pomar estudado encontrava-se em forte deficit de polinização, impossibilitando o vingamento máximo potencial das plantas. Dentre os visitantes florais, Apis mellifera foi a única espécie cujo comportamento de forrageio, abundância e frequência às flores, atendeu os requerimentos de polinização da cajazeira, apresentando, portanto, potencial para uso como polinizador dessa cultura visando a mitigar o deficit de polinização e maximizar a produção de frutos.

The Relationship

Objective of this research; 1) determine the perception of ranchers against the properties and behavior of the leadership of the companion in the Society of Al-Awwaliyah 2) analyze the relationship between productivity breeder with productivity of livestock in the Society of Al-Awwaliyah 3) identify the relationship perceptions of ranchers against the leadership companion with productivity of livestock in the Society of Al-Awwaliyah , The data used in this study are primary and secondary data. Primary data were obtained from questionnaires which stem from ranchers while secondary data sourced from literature in the form of books and articles. Data processing was performed using Chi-square analysis using SPSS software version 21. One of the factors relating to the productivity of ranchers is the perception of ranchers against the leadership of their companion. Leadership companion views of the nature and behavior of which is owned by a companion. Productivity ranchers indirectly related to the productivity of the cattle business. Characteristics breeder visits of age, years of education, experience ranchers, and businesses in addition to ranchers. The results of data analysis showed that there is a significant relationship between business other than ranchers with ranchers productivity. The relationship between the perception of the nature of the companion breeder with productivity ranchers produce Pearson Chi-Square value is 9.751 and Asymp. Sig. (2-sided) of 0.002. This is due to interest ranchers against leadership qualities possessed by a companion who produce prolific ranchers. Ranchers consider that a companion of his leadership qualities are ideal as a companion.
