A influência da temperatura sobre a duração do período de ovo-a-adulto e nas épocas de florescimento de plantas fornecedoras de alimento (néctar) sugere que esse seja um dos fatores que determinam a distribuição da abundância dos machos ao longo do gradiente altitudinal. Os resultados ressaltam a importância de se obter amostras estratificadas em função da altitude quando populações de Euglossini são estudadas, especialmente em localidades com grande variação topográfica. PALAVRAS-CHAVE: Distribuição altitudinal, Euglossini, Floresta Atlântica ABSTRACT - Eufriesea violacea (Blanchard) males were sampled in a small-scale elevational gradient in Southeastern Brazil and showed sequential peaks of abundance from lowest (700 m) to highest (1,100 m) altitudes during the sampling period. The influence of the temperature on the length of the egg-to-adult period and flowering dates of plants producing food (nectar) suggests that it may be one of the factors determining the distribution of male abundance along the altitudinal gradient.

  • A Review of Sampling and Monitoring Methods for Beneficial Arthropods
    insects Review A Review of Sampling and Monitoring Methods for Beneficial Arthropods in Agroecosystems Kenneth W. McCravy Department of Biological Sciences, Western Illinois University, 1 University Circle, Macomb, IL 61455, USA; [email protected]; Tel.: +1-309-298-2160 Received: 12 September 2018; Accepted: 19 November 2018; Published: 23 November 2018 Abstract: Beneficial arthropods provide many important ecosystem services. In agroecosystems, pollination and control of crop pests provide benefits worth billions of dollars annually. Effective sampling and monitoring of these beneficial arthropods is essential for ensuring their short- and long-term viability and effectiveness. There are numerous methods available for sampling beneficial arthropods in a variety of habitats, and these methods can vary in efficiency and effectiveness. In this paper I review active and passive sampling methods for non-Apis bees and arthropod natural enemies of agricultural pests, including methods for sampling flying insects, arthropods on vegetation and in soil and litter environments, and estimation of predation and parasitism rates. Sample sizes, lethal sampling, and the potential usefulness of bycatch are also discussed. Keywords: sampling methodology; bee monitoring; beneficial arthropods; natural enemy monitoring; vane traps; Malaise traps; bowl traps; pitfall traps; insect netting; epigeic arthropod sampling 1. Introduction To sustainably use the Earth’s resources for our benefit, it is essential that we understand the ecology of human-altered systems and the organisms that inhabit them. Agroecosystems include agricultural activities plus living and nonliving components that interact with these activities in a variety of ways. Beneficial arthropods, such as pollinators of crops and natural enemies of arthropod pests and weeds, play important roles in the economic and ecological success of agroecosystems.

  • Hymenoptera: Apidae), with Distributional Modeling of Adventive Euglossines
    Comparative Genital Morphology, Phylogeny, and Classification of the Orchid Bee Genus Euglossa Latreille (Hymenoptera: Apidae), with Distributional Modeling of Adventive Euglossines BY ©2010 Ismael Alejandro Hinojosa Díaz Submitted to the graduate degree program in Ecology and Evolutionary Biology and the Graduate Faculty of the University of Kansas in partial fulfillment of the requirements for the degree of Doctor of Philosophy. Chairperson Michael S. Engel Charles D. Michener Edward O. Wiley Kirsten Jensen J. Christopher Brown Date Defended: November 10, 2010 The Dissertation Committee for Ismael Alejandro Hinojosa Díaz certifies that this is the approved version of the following dissertation: Comparative Genital Morphology, Phylogeny, and Classification of the Orchid Bee Genus Euglossa Latreille (Hymenoptera: Apidae), with Distributional Modeling of Adventive Euglossines Chairperson Michael S. Engel Date approved: November 22, 2010 ii ABSTRACT Orchid bees (tribe Euglossini) are conspicuous members of the corbiculate bees owing to their metallic coloration, long labiomaxillary complex, and the fragrance-collecting behavior of the males, more prominently (but not restricted) from orchid flowers (hence the name of the group). They are the only corbiculate tribe that is exclusively Neotropical and without eusocial members. Of the five genera in the tribe, Euglossa Latreille is the most diverse with around 120 species. Taxonomic work on this genus has been linked historically to the noteworthy secondary sexual characters of the males, which combined with the other notable external features, served as a basis for the subgeneric classification commonly employed. The six subgenera Dasystilbe Dressler, Euglossa sensu stricto, Euglossella Moure, Glossura Cockerell, Glossurella Dressler and Glossuropoda Moure, although functional for the most part, showed some intergradations (especially the last three), and no phylogenetic evaluation of their validity has been produced.

Acad. Colomb. Cienc. 31(120): 415-423, 2007. ISSN 0370-3908. Knowledge on the geographical distribution of orchid bee species in Colombia and most of the Neotropics depends on monitoring and sample methodologies implemented and facilities to access diverse natural regions. In addition, for research on distribution of species, the taxonomic impediment is a problem for the identification and confirmation of some species, although the tribe Euglossini presents a relatively well developed taxonomy.

Entre ellos, las abejas constituyen un eslabón esencial en la polinización de angiospermas que durante millones de años desarrollaron estrategias cada vez más específicas para atraerlas. De esta forma se establece una relación muy fuerte entre am- bos, planta-polinizador, y cuanto mayor es la especialización, tal como sucede en un gran número de especies de orquídeas y cactáceas entre otros grupos, ésta se torna más vulnerable ante cambios ambientales naturales o producidos por el hombre. De esta forma, el estudio de este tipo de interacciones resulta cada vez más importante en vista del incremento de áreas perturbadas o modificadas de manera antrópica en las cuales la fauna y flora queda expuesta a adaptarse a las nuevas condiciones o desaparecer.

  • Hymenoptera, Apidae, Euglossini)
    NEST STRUCTURE AND COMMUNAL NESTING IN EUGLOSSA (GLOSSURA) ANNECTANS DRESSLER (HYMENOPTERA, APIDAE, EUGLOSSINI) Carlos Alberto Garofalo 1 Evandro Camillo 1 Solange Cristina Augusto 1 Bartira Maria Vieira de Jesus 1 Jose Carlos Serrano 1 ABSTRACT. Three nests of Euglossa (Glossura) annectans Dressler, 1982 were obtained from trap nests at Serra do Japi, Jundiai, Sao Paulo State, Brazil. The bees nested in bamboo cane (one nest) and in wooden-boxes (two nests). Sol italY (two cases) and pleometrotic (one case) foundations were observed. Two nests were re-used once by two females working in each of them. Re-using females that shared the nests were of the same generation and each built, provisioned and oviposited in her own cells, characterizing a communal association. The brood development period was related to climatic conditions. Natural enemies included Anthrax oedipus oedipus Fabricius, 1805 (Bombyliidae), Coelioxys sp. (Megachilidae) and Meli/lobia sp. (Eulophidae). KEY WORDS. Apidae, Euglossini, Euglossa annectans, nesting biology, nest re-use Very little is known about the nest structure and nesting habits of the Euglossini. Nests ofonly eight species of ELifriesea Cockerell, 1908, three species ofEulaema Lepeletier, 1841 and 21 species ofEuglossa Latreille, 1802 have been described; these figures correspond to 18.1 % ofthe species ofthree genera (GARO­ FALO 1994). The little information available on such aspects is due to the fact that the nests of these bees are not easily found (MICHENER 1974; DRESSLER 1982; KIMSEY 1987). Utilizing the trap nest technique, GAROFALO et al. (1993) obtained 16 nests of four species of Euglossa and 10 nests of Eufriesea auriceps (Friese, 1899).

  • Flight Energetics of Euglossine Bees in Relation to Morphology and Wing Stroke Frequency
    J. exp. Biol. 116, 271-289 (1985) 271 Printed in Great Britain © The Company of Biologists limited 1985 FLIGHT ENERGETICS OF EUGLOSSINE BEES IN RELATION TO MORPHOLOGY AND WING STROKE FREQUENCY BY TIMOTHY M. CASEY, MICHAEL L. MAY Department of Entomology and Economic Zoology, New Jersey Agricultural Experiment Station, Cook College, Rutgers University, New Brunswick, New Jersey 08903, U.SA. AND KENNETH R. MORGAN Department of Biology, University of California, Los Angeles, California 90024, U.SA. Accepted 10 September 1984 SUMMARY Mass-specific oxygen consumption of euglossine bees during free hovering flight is inversely related to body mass, varying from 66mlO2g~1h~1 in a 1 1 1-0-g bee to 154mlO2g~ h~ in a O10-g bee. Individuals of Eulaema and Eufreisea spp. have smaller wings and higher wing stroke frequency and energy metabolism at any given mass than bees olEuglossa spp. or Exaerete frontalis. Calculated aerodynamic power requirements represent only a small fraction of the energy metabolism, and apparent flight efficiency [aero- dynamic power ( = induced + profile power)/power input] decreases as size declines. If efficiency of flight muscle = 0-2, the mechanical power output of hovering bees varies inversely with body mass from about 480 to 1130 W kg"1 of muscle. These values are 1 -9 to 4-5 times greater than previous predictions of maximum mechanical power output (Weis-Fogh & Alexander, 1977; see also Ellington, 1984c). Mass-specific energy expenditure per wing stroke is independent of body mass and essentially the same for all euglossines. Differences in energy metabolism among bees having similar body mass is primarily related to differences in wing stroke frequency.

Museu Paraense Emílio Goeldi, Coordenação de Zoologia. 2. Universidade Federal da Bahia. EntomoBrasilis 10 (1): 64-68 (2017) Abstract. Orchid bees (Euglossini) are medium to large-sized species with fully or partially metallic body that are relatively common in the Neotropical Region. Nevertheless, the nesting biology of many species remains unknown. Therefore, the objective of this paper is to provide new information on the nesting biology of five species of Euglossini found in urban and forested sites of Brazilian Amazon. The nests ofEufriesea pulchra (Smith) and Euglossa chalybeata Friese were recorded for the first time, found in an active nest of the ant Azteca sp. and in a fallen rotting tree, respectively. The nest of Euglossa townsendi (Linnaeus) was found in the leaf of an ornamental plant Cordyline sp. (Asparagaceae), also newly recorded. Euglossa intersecta Latreille was recorded nesting in an abandoned termite nest, and Euglossa cordata Cockerell was found nesting in a tubular metal window handle. Keywords: Apinae; Bee; Eufriesea; Euglossa; Nest. Notas sobre a biologia de nidificação de cinco espécies de Euglossini (Hymenoptera: Apidae) na Amazônia Brasileira Resumo. As abelhas-da-orquídea (Euglossini) possuem tamanho médio a grande, corpo parcialmente ou completamente metálico e são relativamente comuns na região Neotropical.
