  • Bigger and sweeter passion fruits: effect of pollinator enhancement on
           fruit production and quality
    • Authors: Camila N. JUNQUEIRA; Solange C. AUGUSTO
      Pages: 131 - 140
      Abstract: Abstract Brazil stands out as the world’s largest producer of yellow passion fruit, a species of economic interest which, due to its self-incompatibility, depends on pollinators for fruit formation. The main pollinators of passion fruit are large solitary bees of the genus Xylocopa, commonly known as carpenter bees, which are potential candidates for management. Passion fruit crops exhibit a low density of pollinators and, consequently, a reduction in production. To improve management techniques of X. frontalis and X. grisescens, the general aim of this study was to evaluate the effect of pollinator enhancement on pollination services in passion fruit crop areas. Our results demonstrated that pollinator enhancement was an efficient way to minimize pollination deficit in passion fruit crops, as it promoted the production of a bigger and sweeter fruits. Data obtained in our study are essential to consolidate management techniques for carpenter bees in passion fruit crops.

  • Honeybee worker larvae perceive queen pheromones in their food
    • Authors: Michal Woyciechowski; Karolina Kuszewska; Jędrzej Pitorak; Justyna Kierat
      Pages: 144 - 149
      Abstract: Abstract Honeybee workers develop from fertilised eggs, but those reared in a queenless colony develop into ‘rebel’ workers, which are more queen-like than typical workers. Rebels develop after an old queen leaves with a swarm and before a new queen hatches. We hypothesised that larval food lacking queen mandibular pheromones trigger the rebel phenotype. Larvae reared under queenright or queenless conditions were additionally fed with water or a drop of macerated queen mandibular glands. After following development of the bees and subjecting them to dissection, we found that those reared with a queen or fed the macerated glands under queenless conditions developed into typical workers. Only those workers reared without a queen and without macerated glands added to their food developed into rebels; these rebels had more ovarioles, smaller hypopharyngeal glands, and larger mandibular and Dufour’s glands than did typical workers. This is the first evidence that larval perception of the presence or absence of queen pheromones causes an alternative development strategy.

  • Differential susceptibility to the tracheal mite Acarapis woodi between
           Apis cerana and Apis mellifera
    • Authors: Yoshiko Sakamoto; Taro Maeda; Mikio Yoshiyama; Jeffery S. Pettis
      Pages: 150 - 158
      Abstract: Abstract In Japanese honey bees Apis cerana japonica, infestations of the tracheal mite Acarapis woodi have spread rapidly over the mainland of Japan, causing damage and the collapse of colonies. Meanwhile, infestations by mites in Apis mellifera have hardly been observed in Japan. In this study, we assessed and compared the susceptibility of the two species, A. cerana and A. mellifera, using an inoculation assay. We found that migrating female mites entered the tracheae of more newly emerged bees in both species but more frequently in A. cerana than in A. mellifera. Hence, the higher susceptibility in A. cerana is proposed as a factor causing the explosive epidemic of tracheal mites in only A. cerana in Japan. Moreover, we compared grooming behaviors between the two bee species using an observation assay as a preliminary experiment, although the bees were not exposed to the presence of tracheal mites. From these observations, the frequency of autogrooming (self-grooming) on the thorax in A. cerana was lower than that in A. mellifera. The difference in susceptibility to the mite between these two species may be due to the difference in grooming behavior frequency.

  • Water activity of the bee fungal pathogen Ascosphaera apis in relation to
           colony conditions
    • Authors: Jay A. Yoder; Blake W. Nelson; Leighanne R. Main; Andre L. Lorenz; Andrew J. Jajack; Katherine A. Aronstein
      Pages: 159 - 167
      Abstract: Abstract We report factors that are limiting for Ascosphaera apis growth: water activity (aw) and temperature. Features of A. apis were a high water activity, 0.85–0.90 aw at 25/30 °C and 0.90–0.95 aw at 35 °C. A minimum water activity of 0.95 aw was required to produce spores. None of these characteristics changed from cycling or descending/ascending between low and high water activity media. Growth rates varied between isolates. This new study provides the biological data for monitoring and early prediction of disease outbreaks. Beekeepers should note that A. apis has a high water activity for spore production. Healthy bees that keep the internal brood area hot and dry can critically limit incidence of infection and transmission via spores.

  • Nesting biology and potential distribution of an oil-collecting Centridine
           Bee from South America
    • Authors: Danny Velez; Felipe Vivallo; Daniel Paiva Silva
      Pages: 181 - 193
      Abstract: Abstract Despite their relevance for the maintenance of terrestrial ecosystems, important aspects such as the biology and distribution range remain unknown for most species of bees that occur in the Neotropical region. This makes the monitoring of pollinators and the establishment of conservation policies difficult. In this paper, we provide information on the nesting biology and natural enemies of Centris merrillae. Additionally, we provide a potential distribution model based on previously unknown occurrence records that increase the distribution range of this species through northern South America and the Caribbean. The production of such biological and biogeographic information is important to support future field surveys.

  • Introduction of Aethina tumida (Coleoptera: Nitidulidae) in the regions of
           Calabria and Sicily (southern Italy)
    • Authors: Anna Granato; Bianca Zecchin; Chiara Baratto; Véronique Duquesne; Enrico Negrisolo; Marie-Pierre Chauzat; Magali Ribière-Chabert; Giovanni Cattoli; Franco Mutinelli
      Pages: 194 - 203
      Abstract: Abstract Aethina tumida (small hive beetle, SHB) was first detected in September 2014 in Calabria region, southern Italy, and in a single apiary in Sicily in November 2014. In September 2015, SHB was again recorded in Calabria, and in 2016, only sentinel honey bee nucleus colonies were found to be infested. Its phylogenetic relationship and possible origin were investigated comparing the cox1 sequences with the corresponding region available in the GenBank database. The neighbour-joining method revealed that the first Italian specimen belonged to a group also containing an African specimen from Cameroon. The Italian specimens differ from the SHBs spread worldwide and are split into two different groups: group B1 includes the AfricCam3 sequence and the first SHB identified in Calabria; group B2 includes specimens from Calabria and the only one from Sicily which share identical cox1 sequences. SHB in Italy appears to have been introduced from Africa and includes independent or contemporary incursions in the two concerned regions. The most likely scenario is that SHB was introduced into Calabria followed by man-mediated migration to Sicily.

  • Newly emerged workers of the stingless bee Scaptotrigona aff. depilis
           prefer stored pollen to fresh pollen
    • Authors: Ayrton Vollet-Neto; Camila Maia-Silva; Cristiano Menezes; Vera Lucia Imperatriz-Fonseca
      Pages: 204 - 210
      Abstract: Abstract Like in honey bees, the pollen collected and stored by stingless bees usually undergoes a fermentation process characterized by increase in moisture, lactic acid, and proliferation of microorganisms. We tested whether 2-day-old Scaptotrigona aff. depilis workers were more attracted to and consumed fermented pollen from old pollen pots (>7 days) or fresh pollen collected from the corbicula of foragers. In each bioassay, we offered both types of pollen to 40 inexperienced workers of one colony for 24 min, and repeated the procedure in ten different colonies. In all cases, there were more bees feeding on the fermented pollen, which was 2.2 times more consumed than the fresh pollen. Our results suggested that fermented pollen attracted more bees potentially due to innate preference of young bees, higher levels of attractant substances present in fermented pollen, or due to associative learning reminiscent from larvae feeding habits.

  • Worker size in honeybees and its relationship with season and foraging
           distance
    • Authors: Romain Sauthier; Robbie I’Anson Price; Christoph Grüter
      Pages: 234 - 246
      Abstract: Abstract Workers in many eusocial insect species show considerable size variation within a colony. Honeybees (Apis mellifera) vary little in size compared to other eusocial bee species, but there is evidence for a link between worker size and behaviour. In this study, we investigated how size variation and the average size of honeybee foragers change during a foraging season. We also tested the influence of colony weight and swarming on worker size. Finally, by analysing waggle dances, we tested if forager size is linked to foraging distance, between and within colonies. We found that the size of foragers significantly increases over the foraging season. Swarming did not appear to affect worker size, but colony size was overall positively linked to wing length and leg width. However, we did not find a relationship between foraging distance and forager size. We discuss how the constant size of brood cells and an efficient communication between foragers could lead to a narrower size range.

  • Hide and seek: is the solitary bee Monoeca haemorrhoidalis trying to
           escape from its cleptoparasite Protosiris gigas (Hymenoptera, Apidae:
           Tapinotaspidini; Osirini)?
    • Authors: Léo Correia da Rocha-Filho; Gabriel A. R. Melo
      Pages: 262 - 270
      Abstract: Abstract Cleptoparasites play a key ecological role by reducing their host populations. In order to study the phenological patterns of the natural enemies of the bee Monoeca haemorrhoidalis (Smith), four emergence traps were installed in two nest aggregations during the activity period of this solitary bee species. Four species of natural enemies were sampled in the emergence traps: Tetraolytta gerardi (Pic), Tetraonyx distincticollis Pic (Meloidae), Protosiris gigas Melo (Apidae), and Pseudomethoca spixi (Diller) (Mutillidae). Monoeca haemorrhoidalis showed emergence patterns characterized by bimodal curves with two distinct peaks throughout its activity period in both years. Individuals of P. gigas started to emerge during the first peak of its host, but the emergence curve of this cleptoparasite was followed by a decline in abundance of M. haemorrhoidalis specimens in both years. The abrupt decline in the emergence period of M. haemorrhoidalis could be a temporal strategy against the attack of P. gigas since the activity period of this cuckoo bee occurred during the lowest number of emergent host individuals.

  • Toxicity of thiametoxam on in vitro reared honey bee brood
    • Abstract: Abstract Pesticides are a possible cause of pollinator decline and honey bee colony losses experienced in several countries in recent years. In the past years, many north-west Italian beekeepers reported the presence of dead brood in field apiaries during neonicotinoid-coated maize sowing; therefore, a possible role of these insecticides was suspected. The objective of this study was to test this hypothesis. Laboratory repeated dose toxicity tests on in vitro reared larvae were carried out using thiamethoxam. The repeated treatment median lethal concentration (LC50) and the median lethal dose (LD50) 14 and 19 days after grafting were calculated and resulted of the same order of magnitude of realistic brood exposure under a worst-case scenario. Various sublethal effects, like brownish larvae, duplication of the pupal integument, delay in development, and deformed adults were also observed.

  • Toxicity of organophosphorus pesticides to the stingless bees
           Scaptotrigona bipunctata and Tetragonisca fiebrigi
    • Authors: Andressa Linhares Dorneles; Annelise de Souza Rosa; Betina Blochtein
      Abstract: Abstract This study estimated the toxicity of the insecticides chlorpyrifos and phosmet to the stingless bees Scaptotrigona bipunctata and Tetragonisca fiebrigi. The results showed significant differences in susceptibility between the tested species, indicating that S. bipunctata are more tolerant to chlorpyrifos than T. fiebrigi in both assays. In contrast, the two tested stingless bee species showed no significant differences in susceptibility to phosmet. Our findings indicated that the insecticides chlorpyrifos and phosmet are potentially dangerous to S. bipunctata and T. fiebrigi both topically and by ingestion. It is essential to propose measures to minimize the impact of these products on pollinators. This study is the first evaluation of the lethal effects of the insecticides chlorpyrifos and phosmet to S. bipunctata and T. fiebrigi, and it provides important support for future studies on pesticide toxicity in stingless bees.

  • Molecular cloning, expression and oxidative stress response of the
           vitellogenin Gene ( AccVg ) from Apis cerana cerana
    • Authors: Weixing Zhang; Zhenguo Liu; Ming Zhu; Lanting Ma; Ying Wang; Hongfang Wang; Xingqi Guo; Baohua Xu
      Abstract: Abstract Vitellogenin (Vg) is a yolk precursor protein in most oviparous females. However, Vg has not been studied in the Apis cerana cerana. In this work, the Vg gene of the A. cerana cerana has been cloned and sequenced. The gene codes for a protein consisting of 1770 amino acids in seven exons with a predicted molecular mass and isoelectric point of 200 kDa and 6.46, respectively. Additionally, an 807-bp 5′-flanking region was isolated, and potential transcription factor binding sites associated with development and stress response were identified. Quantitative real-time PCR analysis showed that AccVg is highly expressed in pupae during different developmental stages. In addition, the expression of AccVg could be induced by cold (4 and 16 °C), CdCl2, and pesticide treatment. Real-time quantitative PCR (RT-PCR) and western blot analyses indicated that AccVg transcription was induced by various abiotic stresses. Western blot was used to measure the expression levels of AccVg protein. Taken together, these results suggest that AccVg most likely plays essential roles in antioxidant defence and that it may be of critical importance to honey bee survival.

  • Coumaphos residues in honey, bee brood, and beeswax after Varroa treatment
    • Authors: Blanka Premrov Bajuk; Katarina Babnik; Tomaž Snoj; Luka Milčinski; Metka Pislak Ocepek; Martina Škof; Vlasta Jenčič; Ayhan Filazi; Darinka Štajnbaher; Silvestra Kobal
      Abstract: Abstract Residues of acaricide coumaphos were assessed in honey, bee brood, and beeswax during a 2-year field experiment. Honey, bee brood, and beeswax samples were collected before and after routine use of coumaphos in the treatment of bee colonies against varroosis in two consecutive years. Determination of coumaphos in honey and bee brood was based on RP-HPLC with UV detection after a liquid-liquid extraction with hexane or ethyl acetate. Coumaphos in beeswax was identified and quantified by GC/MS. Results indicate the undetectable presence of coumaphos in honey. In bee brood, coumaphos was observed after the treatment. In beeswax, the accumulation of coumaphos was determined not only in hives where it was used but also in hives nearby in which coumaphos was not used. Results indicate the accumulation of coumaphos in bee brood and beeswax. Due to the coumaphos accumulation this drug should be used only in strongly affected bee colonies.

      Abstract: Abstract Orchid bees (Apidae, Euglossini) are important pollinators in the Amazon forest. In eastern Brazilian Amazon, secondary forest and pastures are being replaced by oil palm plantations. Here, we tested the role of forest reserves and riparian corridors in maintaining orchid bees. We sampled bees in three different soil-type uses, comparing richness, abundance, and assemblage composition. Estimated richness was lowest in palm plantations than in forest reserves and riparian corridors on diversity of orchid bees. Riparian corridors had the highest abundance, followed by reserves, and oil palm plantations. Bee assemblage also varied with land cover, with the reserves having the most distinct composition. We also identified indicator bees for primary forest. Our results demonstrate riparian corridors and forest reserves can maintain orchid bees in oil palm landscapes.
