“…Bees in the CCRI41 group consumed less pollen than control bees during the course of the assay and a similar pattern occurred for bees exposed to imidacloprid-contaminated pollen. The antifeedant effect in group exposed to imidacloprid-contaminated pollen was consistent with previous studies on honey bees (Kirchner 1999; Ramirez-Romero et al 2005; Ramirez-Romero et al 2008b) and on Homoptera (Nauen et al 1998a, b). The detection and uptake of nectar and pollen involves sophisticated nervous system activity which can be perturbed by the presence of chemical insecticide, whether that behaviour took place in the hive or outside (Desneux et al 2007).…”

Transgenic Cry1Ac + CpTI cotton (CCRI41) is increasingly planted throughout China. However, negative effects of this cultivar on the honey bee Apis mellifera L., the most important pollinator for cultivated ecosystem, remained poorly investigated. The objective of our study was to evaluate the potential side effects of transgenic Cry1Ac + CpTI pollen from cotton on young adult honey bees A. mellifera L. Two points emphasized the significance of our study: (1) A higher expression level of insecticidal protein Cry1Ac in pollen tissues was detected (when compared with previous reports). In particular, Cry1Ac protein was detected at 300 ± 4.52 ng g−1 [part per billion (ppb)] in pollen collected in July, (2) Effects on chronic mortality and feeding behaviour in honey bees were evaluated using a no-choice dietary feeding protocol with treated pollen, which guarantee the highest exposure level to bees potentially occurring in natural conditions (worst case scenario). Tests were also conducted using imidacloprid-treated pollen at a concentration of 48 ppb as positive control for sublethal effect on feeding behaviour. Our results suggested that Cry1Ac + CpTI pollen carried no lethal risk for honey bees. However, during a 7-day oral exposure to the various treatments (transgenic, imidacloprid-treated and control), honey bee feeding behaviour was disturbed and bees consumed significantly less CCRI41 cotton pollen than in the control group in which bees were exposed to conventional cotton pollen. It may indicate an antifeedant effect of CCRI41 pollen on honey bees and thus bees may be at risk because of large areas are planted with transgenic Bt cotton in China. This is the first report suggesting a potential sublethal effect of CCRI41 cotton pollen on honey bees. The implications of the results are discussed in terms of risk assessment for bees as well as for directions of future work involving risk assessment of CCRI41 cotton.

“…Likewise, aggression was absent between colonies of different aggregations. This atypically peaceful behavior contrasts with other studies on stingless bees that found relatively strong aggression between con-or heterospecific non-nestmate individuals (Johnson and Hubbell, 1974;Johnson, 1977, 1978;Howard, 1985;Inoue et al, 1999;Kirchner and Friebe, 1999;Nunes et al, 2008;.…”

Genetic Relatedness and Chemical Profiles in an Unusually Peaceful Eusocial Bee

et al. 2011

Colonies of the stingless bee Tetragonilla collina frequently occur in unusually high densities and in direct neighborhood (nest aggregations), in rainforests of Southeast Asia. To investigate whether close relatedness and/or similar chemical profiles facilitate the co-occurrence of multiple T. collina colonies, we investigated aggressive behavior, genetic relatedness and cuticular hydrocarbon (CHC) profiles within and between colonies and nest aggregations. Although 17 out of 19 colonies within aggregations were largely unrelated, intraspecific aggression between different colonies was basically absent both within and among aggregations. This lack of aggression should favor social parasitism and hence the occurrence of unrelated individuals within a colony. However, low within-colony relatedness was found in only five out of 19 colonies where it may be explained by queen turnover or the occurrence of foreign workers. CHC profiles of colonies within and among aggregations were statistically different. However, many workers could chemically not be assigned to their maternal colony, indicating considerable overlap among colonies in odor profiles of workers. Moreover, odor profiles tended to be more similar within than among aggregations, although most colonies were unrelated. Thus, CHC profiles were a poor indicator of relatedness in T. collina. The lack of correlation between relatedness and chemical similarity in T. collina may be explained by the incorporation of resin-derived terpenes in their CHC profiles. The composition of these terpenes was highly similar among colonies, particularly within aggregations, hence potentially decreasing chemical distinctiveness and increasing behavioral tolerance.

“…Intraspecific conflict can only take place if bees discriminate nest mates from non-nest mates. Nest mate discrimination has been demonstrated in several Melipona (Breed and Page, 1991;Inoue et al, 1999) and Trigonine species (Suka and Inoue, 1993;Kirchner and Friebe, 1999) and seems common in stingless bees. Fights between non-nest mates usually end in the death of one or both of the bees (Breed and Page, 1991;Biesmeijer and Slaa, pers.…”

Information flow and organization of stingless bee foraging

-Stingless bees (Hymenoptera, Apidae, Meliponini) live in populous permanent colonies and face the same problem as other foraging social insects: how to coordinate the worker's actions and respond to the spatio-temporal uncertainties of food availability in their habitat. Here we review the (social) information used by individual foragers and how organized collective foraging emerges from the individual actions. We also address intra-and interspecific competition for food and the impact of the African honey bee on stingless bee collective foraging.Melipona / Trigona / self-organization / communication / foraging / Africanized honeybee / insect society
