1. Native bee fauna of tomato crops: a comparison of active sampling and pan trapping methods
RESUMO O tomate é amplamente cultivado em todo o mundo e requer polinização por abelhas nativas ou manejadas para realizar o pleno potencial de produção dos frutos. Para investigar a riqueza e abundância de espécies de abelhas nativas em plantações de tomate do Centro-Oeste do Brasil, dois métodos de amostragem (armadilhas pan-trap e amostragem ati

2. Bioactivity of essential oils from Artemisia against Diaphania hyalinata and its selectivity to beneficial insects
ABSTRACT: The demand for effective insecticides in pest control with low toxicity to the non-target organisms, such as natural enemies and pollinators, is increasing steadily. A good alternative for synthetic insecticides is natural compounds, including essential oils (EO). This work assessed toxicity of essential oils extracted from Artemisia annua, A. absi

3. Are native bees and Apis mellifera equally efficient pollinators of the rupestrian grassland daisy Aspilia jolyana (Asteraceae)?
ABSTRACT Most angiosperms rely on animals for pollination, and insects, especially bees, are being the most frequent pollinators. Many native Neotropical plants are frequently visited by the invasive honeybee (Apis mellifera), but its role in the pollination of these plants has been little investigated. We assessed the contribution of various floral visitors

4. Functional specialization and phenotypic generalization in the pollination system of an epiphytic cactus
ABSTRACT Plant-pollinator interactions range from obligatory specialists to facultative generalists, and floral morphology and pollination system may not match completely. The floral biology, reproductive system and floral visitors of a species of the tribe Rhipsalideae were investigated with a focus on the consistency between the pollination system and the

5. Variações altitudinais na diversidade e composição em espécies de vespas e abelhas (Hymenoptera: Aculeata)
Distribution patterns of insects along elevational gradients have been described for many tropical mountains. According to the hypothesis of elevational gradient, species richness and abundance of species tend to decrease in higher altitudes. Aculeata is considered a monophyletic lineage of Hymenoptera order. They are important pollinators, but there are few

6. Abelhas visitantes florais e potenciais polinizadores da cajazeira (Spondias mombin L.) sob cultivo, na Chapada do Apodi, Cearà / Bee and flower visitors from potential pollinators mombin (Spondias Mombin L.) under cultivation in Apodi Plateau, State of CearÃ
The research was carried out from November of 2009 to January of 2010, in the Apodi plateau, situated in the county of Limoeiro do Norte, state of CearÃ. It was used 32 cajazeira trees (Spondias mombim L.) of the Lagoa Redonda cloning tree, grafted on the umbuzeiro tree (Spondias tuberose A.). The objective was to verify some variables regarding to floral b

7. Polinização entomófila de abobrinha, Cucurbita moschata (Cucurbitaceae)
The objectives of this work were to determine the squash entomofauna in the region of Viçosa, Minas Gerais state, to study their behavior on flowers and their importance for pollination, verifying the role of each pollinator. The most common species were Trigona spinipes (Fabricius), Trigona hyalinata (Lepeletier), Apis mellifera (L.) and Melipona quadrifas

8. Distribuição e disponibilidade de recursos florais e estratégias de forrageamento na interação entre beija-flores e Palicourea rígida (Rubiaceae)
Some pollination mechanisms represent mutualistics interactions, in which the plants offer nectar and pollen and the pollinators carry the pollen grains. The hummingbirds are the more specialized pollinators among the birds, and their high energetic cost to fly, force them to develop feeding strategies to obtain the highest energetic gains with the lowest co

9. Visitors of the bees flowers(Bixa orellana L.) and pollination efficiency / Abelhas visitantes das flores do urucuzeiro (Bixa orellana L.) e suas eficiÃncias de polinizaÃÃo
A pesquisa de campo foi conduzida na Fazenda Kiara Coeli localizada no municÃpio de Caucaia, estado do CearÃ. A coleta dos dados ocorreu de marÃo a agosto de 2007. Em um plantio de 6 ha constituÃdo por urucuzeiros hÃbridos. O trabalho objetivou conhecer os requerimentos de polinizaÃÃo do urucuzeiro (Bixa orellana L.), identificar seus visitantes flora

10. Estrutura genética e sociogenética das populações e ninhos de Euglossini (Hymenoptera: Apidae) determinadas por meio de microssatélites.
Euglossine bees are important pollinators of many Neotropical plant species, particularly orchids which could present a species-specific bee-flower relationship, essential to the reproductive success of these plants. Orchids produce chemical compounds to attract males of Euglossine bees (the effective pollinators of the orchids), and these compounds were iso

11. Incompatibilidade heteromórfica em Eichhornia Azurea (Pontederiaceae) no Pantanal da Nhecolandia, Mato Grosso do Sul
In heterostylous plants pollination between anthers and stigmas of equivalent heights are often compatible, but any other type of cross or self-pollination result in partial or total incompatibility. Eichhornia azurea is a fluctuant aquatic macrophyte, fixed in the substrate that is generally found in lagoons, rivers and flooded areas in South America. Previ

12. Polinização de Passiflora edulis f. flavicarpa (Passiflorales, Passifloraceae), por abelhas (Hymenoptera, Anthophoridae) em Campos dos Goytacazes, Rio de Janeiro
The yellow passion Passiflora edulis f. flavicarpa Deg. is allogamous, self incompatible, and it depends of insects pollinators to disseminate the pollen grains. The field work was conducted at Campos dos Goytacazes, Rio de Janeiro, Brazil, from October 17 to November 9 and December 12 to 21, 1995. It was analyzed 1565 flower buds, from which 423 showed well
