The nests of social insects provide suitable microenvironments for many microorganisms as they offer stable environmental conditions and a rich source of food [1, 2, 3 and 4]. Microorganisms in turn may provide several benefits to their hosts, such as nutrients and protection against pathogens [1, 4, 5 and 6]. Several examples of symbiosis between social insects and microorganisms have been found in ants and termites. These symbioses have driven the evolution of complex behaviors and nest structures associated with the culturing of the symbiotic microorganisms [5, 7 and 8]. However, while much is known about these relationships in many species of ants and termites, symbiotic relationships between microorganisms and social bees have been poorly explored [3, 4, 9 and 10]. Here, we report the first case of an obligatory relationship between the Brazilian stingless bee Scaptotrigona depilis and a fungus of the genus Monascus (Ascomycotina). Fungal mycelia growing on the provisioned food inside the brood cell are eaten by the larva. Larvae reared in vitro on sterilized larval food supplemented with fungal mycelia had a much higher survival rate (76%) compared to larvae reared under identical conditions but without fungal mycelia (8% survival). The fungus was found to originate from the material from which the brood cells are made. Since the bees recycle and transport this material between nests, fungus would be transferred to newly built cells and also to newly founded nests. This is the first report of a fungus cultivation mutualism in a social bee.

Eigth phytoseiid species were tested to evaluate and compare their potential as predators of Tetranychus evansi Baker & Pritchard and T. urticae (Koch). The study was conducted using arenas of excised nightshade (Solanum douglasii Dunal) and Lima Bean (Phaseolus vulagris, L.) leaves infested with either Tetranychus species. When the prey was T. evansi, the predators Amblyseius californicus (McGregor) and Phytoseiulus persimilis Athias-Henriot from Ventura, california, showed the highest oviposition rates. However those rates were 4 to 6 times lower than rates for the same predators feeding on T. urticae. Only A. californicus and the strain of P. persimilis from Beni-Mellal, Morocco, had survivorship higher than 50% 8 days after the beginning of the experiment.The results indicated that T. evansi is an unfavorable prey for all the phytoseiids tested. |
