The Yucatán peninsula is the most important of honey-producing region in Mexico which is the second most important source of income after agriculture. In the Maya area of Quintana Roo, beekeepers have a common problem of bee predation by ants, resulting in the loss of hives and their products. The objective was to identify the species of ants that prey on A. mellifera bees in apiaries in Kancabchén, Quintana Roo. These predatory ants were collected in three apiaries, by means of traps and manual capture in the dry and rainy seasons (2017), these were identified using taxonomic keys. The presence of five species of predatory ants in apiaries is reported for the first time: Eciton burchellii, Eciton mexicanum, E. vagans, Labidus praedator, and Nomamyrmex hartigii are all army ants and as such, do not establish permanent nests or attack at a specific time. This makes it difficult for the beekeepers to by always present now of the attack; and when they coincide, the only traditional control is simply to burn the ants with all the bees and the hive. Because these army ants have nomadic or seminomadic habits, it is difficult to establish an effective management program for Mayan beekeepers in Quintana Roo. [ABSTRACT FROM AUTHOR]

Bees are susceptible to diseases, which cause significant economic losses in beekeeping. The objective was to evaluate the prevalence of Varroa sp, Nosema sp and Acarapis in apiaries located in two regions in Campeche, Mexico. 116 bee samples from 10 apiaries were evaluated. The prevalence of Varroa was lower in Hopelchén compared to Sihochac (98.5% and 100%), the prevalence of Nosema was lower in Hopelchén compared to Sihochac (85.9% and 88.0%). The Varroa infestation level was higher in Hopelchén compared to Sihochac (7.32 and 3.73 mites in 100 bees), however, the Nosema infestation level was lower in Hopelchén compared to Sihochac (78x105 and 23x106 spores per bee), not the presence of Acarapis was found in none of the evaluated regions. In both regions a positive correlation was found between the presence of Nosema and Varroa. There is a 1.08 higher probability of finding Nosema in the presence of Varroa. We conclude that in both regions there is a high prevalence of Varroa and Nosema and the presence of Acarapis was not detected. [ABSTRACT FROM AUTHOR]

Colombia has agricultural roots of great wealth, additionally its variety of climate, geography and culture, it is known as the second most biodiverse country in the world, this allows its ecosystems to be perfect for the sustainability of hives and the life of bees. However, no matter how rich the country is, there is not knowledge about the importance of bees and the main factors that impact the sustainability of beekeeping companies. In the department of Quindío, is evidenced in losses economic that derive from the mismanagement of the apiaries and the spraying of agrochemicals in sectors surrounding the hives.

In the Quimis area of the Jipijapa Canton, an investigation was carried out related to the characterization of plant species that provide sustenance to bees in the production of honey that is used by local residents involved in the Aroma y Miel Association, among other uses, to market it. The objective of this study was based on characterizing the melliferous species of the tropical dry forest oriented to its conservation. Seven active apiaries distributed within the enclosure were selected, where four weekly samplings were made, with a total of 28 transects of 20 m x 50 m, taking as a starting point the apiaries to identify and count the number of species of apicultural use. A total of 31 species, 1,527 individuals, belonging to 16 families were determined. The botanical family with the highest abundance was Fabaceae with 290 individuals, and the most abundant species were Ceiba trichistandra (A. Gray) Bakh and Prosopis pallida (Willd.) Kunth, due to the greater beekeeping use and commercialization. The most frequent biological types were trees, followed by shrubs, herbaceous and lianas, respectively. The months of greatest flowering are from March to the beginning of October. [ABSTRACT FROM AUTHOR]

Cassia moschata Kunth is one of many hosts of Caryedon gonagra (F.) and an alternative host to Achroia grisella F., this later is known as secondary pest of apiaries, where the moth fed on seeds and later to hibernate there, although alternatively it may feed on beehive and become a secondary beehive pest. Both species together may reduce significantly the seed feasibility of C. moschata, where C. gonogra destroy 72.8% and A. grisella 11.46%, but both may damage 84.26% of the seed, just leaving only some healthy seeds.

Objective. Microbiologically characterize dry and frozen pollen produced in the municipality of Viracachá-Boyacá. Materials and methods. Through a quantitative descriptive cross-sectional study, samples from 5 apiaries were taken, each with 10 hives, separating the pollen dry and frozen, determining for each sample: mesophilic aerobes, total coliforms, fecal coliforms, Staphylococcus aureus, Clostridium sulfite reducer, and fungus. The data obtained were analyzed according to international regulations and compared with research results in other countries. Results. Total and fecal coliforms were found in three of the five apiaries evaluated and only in dried pollen samples. Also, in two apiaries when dry pollen was analyzed, Staphylococcus aureus was found. The microbiological results of most samples are within the ranges of some international regulations; however, the best results in terms of microbiological quality were determined for frozen pollen. Conclusions. The pollen freezing process offers advantages related to maintaining microbiological quality compared to the drying process. It is necessary to evaluate the microbiological quality of both products throughout the storage time. [ABSTRACT FROM AUTHOR]

During months of June, July, August September in 2006, a study of melisopalinology was developed in three places near Popayan, aiming to determine the predominant apian flora in the study zone. The pollen types recollected by Apis mellifera and the flower blooms collected on the field during the study were analyzed using the Lactic Acetolysis technique. From the 40 types of pollen collected, by means of microscopy only 24 were identified among the pollen found in the beehives. [ABSTRACT FROM AUTHOR]

The aim of this work was to evaluate the acaricide efficacy of Amivar® (amitraz, Apilab, Argentina)to control Varroa destructor Anderson & Trueman, in Apis mellifera colonies during the autumn 2003. Work was done at "Centro de Extensión Apícola "experimental apiary located in Coronel Vidal, province of Buenos Aires. Twenty Langstroth liives were used divided in two equal groups. The first group received one strip of Amivar® (amitraz, 1 gr) in the center of brood area. The second one represented the control group. Dead mites were collected weekly from special floors designed to avoid mite removal by adult honeybees. Then, a total of three doses of 5 ml of Oxavar® at seven days period (64.6 g/l oxalic acid in destilled water) were placed in each colony to kill remanent mites and the acaricide efficacy was calculated. Amivar® showed an average acaricide efficacy of 85.05% ± 3.39 (range =79.5 - 91.6), showing significant differences with control group (p<0.05). No negative effect on honeybee brood was recorded. These results suggest that Amivar® is effective to control the parasite. [ABSTRACT FROM AUTHOR]
