Las abejas sin aguijón son importantes para los ecosistemas por su papel ecológico como polinizadores. En Nicaragua se sabe poco acerca de su diversidad. En este trabajo, se realizó el primer inventario de abejas sin aguijón en el corredor biológico Paso del Istmo de Rivas, Nicaragua, en los municipios de Cárdenas, San Juan del Sur y Rivas. Se realizaron 31 muestreos dirigidos en plantas en floración en los tres municipios en diferentes agroecosistemas. La colecta se hizo con la técnica de red entomológica principalmente en plantas en floración visitadas por las abejas. Se hizo búsqueda de material bibliográfico que demuestren registros de abejas sin aguijón, actualizando de esta manera las especies reportadas en Nicaragua. En total, se colectaron 109 ejemplares correspondiendo a 11 géneros y 21 especies. Predominan los géneros

Son polinizadores de una gran variedad de plantas, muchas de ellas cultivos de gran importancia comercial como los jitomates y los chiles y son componentes fundamentales de los ecosistemas donde habitan. Muchas especies están amenazadas por el crecimiento urbano, el cambio climático y el desarrollo de la agricultura a escala industrial aunque, paradójicamente, algunas especies son indispensables en la agricultura protegida. En este libro se reúne el conocimiento actual sobre las 22 especies nativas de abejorros mexicanos que se reconocen formalmente y sobre una especie introducida, precisamente asociada con la agricultura industrial. Aunque no se puede considerar como una obra definitiva sobre los abejorros mexicanos, es una primera propuesta encaminada a condensar aspectos generales de la biología y la conservación de los abejorros mexicanos, en combinación con un tratamiento tax...

Para ello, se hicieron muestreos intensivos de estas abejas, con lo cual se reunieron registros de distribución, incluyendo las aportadas por investigadores, las presentes en colecciones y los reportados en la literatura. Se tienen 12 registros nuevos de especies de abejas sin aguijón para Oaxaca y se confirma la presencia en Chiapas de Paratrigona opaca. Adicionalmente, se discute sobre la distribución de estas abejas en estos estados y el país. Se espera que la información sobre la fauna y la distribución de las abejas sin aguijón ayude en los esfuerzos de conservación regional, uso de estas abejas en la meliponicultura y la polinización.

These secretions that are involved in bumblebee pre-mating recognition provide efficient diagnostic characters for species delimitation. The subgenus Thoracobombus is the largest group of bumblebees and is found in the Palearctic, Nearctic, and Neotropical regions. Here, the cephalic labial gland secretion (CLGS) composition of six Mexican Thoracobombus bumblebee species are analyzed: Bombus diligens , B. medius , B. mexicanus , B. pensylvanicus , B. trinominatus , and B. weisi . Our results suggest the presence of two new potential species into the formerly recognized B. weisi as well as one new potential species in the taxon presently identified as B. pensylvanicus . Moreover, the male of B. pensylvanicus , known to congregate at nest sites awaiting the emergence of virgin queens, is characterized by low concentrations of the C16 component. This observation raises the possibility that courtship behavior as well as environmental constraints could affect the role of the male bumblebees' CLGS.

In this study, we examine the effect of Quaternary climate instability on population genetic variability of a bumble bee pollinator species, in western North America. Pleistocene and contemporary habitat suitability (HS) was estimated with an environmental niche model (ENM) by associating 1,035 locality records with 10 bioclimatic variables. To estimate genetic variability, we genotyped 380 individuals from 33 localities at 13 microsatellite loci. Bayesian inference was used to examine population structure with and without a priori specification of geographic locality. We compared isolation by distance (IBD) and isolation by resistance (IBR) models to examine population differentiation within and among the Bayesian inferred genetic clusters. Furthermore, we tested for the effect of environmental niche stability (ENS) on population genetic diversity with linear regressi...

In particular, the geographically complex region of Mesoamerica harbors unusually high levels of biodiversity. Little is known about the genetic diversification of insects in this region, even though they represent a large component of species richness. The bumble bee, Bombus ephippiatus, can serve as a model in which to study insect/pollinator evolution in Mesoamerica. Moreover, bumble bees are important commercial and native pollinators in this region, yet the importation of non-native species for crop pollination has the potential for detrimental ecological consequences throughout the region. Previous phylogenetic research by these authors on Bombus ephippiatus has revealed that this species is a species complex comprising at least four distinct genetic lineages across Mesoamerica, with the Nicaraguan Depression and the Isthmus of Tehuantepec serving as geographic ...

Records of gynandromorphic bees recently documented in the literature are also summarized. In less than a decade, more than 20 new cases were documented in 15 species and five genera previously unknown; as of today, gynandromorphs are recorded ...
