“…They found that the amount of provisions put in a cell was inversely related to the number of workers that discharged into it. The model as formulated by Velthuis and Sommeijer [18] and the observations of Darchen and DelageDarchen [2,3] on M. beecheii all stress the importance of food conditions for the determination of caste in Melipona. Since queens were found to take up larval food from both gyne-and worker-producing cells in apparently similar quantities (compare data presented in Tab.…”

“…In Melipona, gynes emerge from cells equal to worker cells. A model for caste polymorphism in Melipona based solely on genetic factors [5,6] was shown to be incomplete; food quantity and quality were also found to be of importance in M. beecheii [2,3]. Velthuis and Sommeijer [18] added a physiological component to Kerr's model in which only individuals heterozygous for two genes (each with two alleles) will develop into queens.…”

queen stays near the cell, and a pre-discharge phase, lasting several minutes and characterized by excited workers, inserting their body in the cell, starts the process. Next, the queen violently taps the workers that insert their body in the cell with her antennae and forelegs, stimulating them to discharge larval food until the cell receives its full amount. During this discharge phase, the queen makes inspections of the cell, may consume some of the larval food, and eats INTRODUCTIONIn stingless bees (Meliponinae), cells are mass-provisioned by workers before queen oviposition and subsequent cell closure, in a characteristic process [1,[12][13][14]16] reviewed by Sakagami [11]. For Melipona, where only one cell is oviposited at a time, the food provisioning and oviposition process (POP) begins with the arrival of the queen at a completed 'collared' cell. The Original articleCell provisioning and oviposition in Melipona beecheii (Apidae, Meliponinae),with a note on caste determination Johan Wilhelm VAN Abstract -We examined the food provisioning and oviposition process (POP) for worker-and gyne-producing cells of Melipona beecheii. POPs for both castes did not differ significantly in duration and number of trophic eggs oviposited by workers in the cells. The frequency of food discharges by workers in gyne-producing cells was significantly less than in worker-producing cells. This result is discussed in relation with caste determination. Seventy percent of all POPs took place at night. We hypothesized that foraging activities during the daytime reduced the number of workers available in the nest for provision of food to workers that participated in the POPs. It was found that the number of trophic eggs laid by workers during a POP was positively correlated to the preceding extra-oviposition period.

“…By contrast, in all other genera of stingless bees, e.g. Trigona, caste is nutritionally rather than genetically determined and queens are normally produced from larger, specially constructed royal cells which are provisioned with more, but samequality, food (Darchen and Delage-Darchen, 1971;Camargo, 1972;Hartfelder and Engels, 1989;Engels and Imperatriz-Fonseca, 1990;Figs. 1b, 2a).…”

Miniature queens in stingless bees: basic facts and evolutionary hypotheses

et al. 2006

-Some stingless bees are known to produce both large queens, reared from larger royal cells, and small "miniature" queens, reared from worker cells. Here we review what is known about miniature queens, and evaluate some major evolutionary hypotheses as to why they are produced. One hypothesis -that miniature queens are females who selfishly evade an intended worker fate -is shown to receive significant support. In particular, there is increasing evidence that the decision to become a miniature queen may be under genetic control of the developing females themselves. In addition, data from several species show that females gain significant fitness benefits from doing so, since miniature queens are frequently observed heading colonies and often are as productive as normal-sized queens. On the other hand, in some species miniature queens have a reduced fecundity or may have lower chances of being chosen as a new queen. This shows that the strategy may also have costs. Queens of the genus Melipona, which are also reared from worker-sized cells, are suggested to have the same evolutionary origins as miniature queens. queen dimorphism / miniature queens / stingless bees / caste fate conflict / Apidae / Meliponini

“…Queen-rearing techniques for stingless bees are based mainly on the overfeeding of female larvae in vitro (Baptistella et al 2012;Menezes et al 2013), since castes determination system in most stingless bee genera depends mainly on trophic factors (Darchen and Delage-Darchen 1971). Female larvae destined to become queens receive more larval food in the bigger (royal) cells than female larvae destined to become workers reared in smaller brood cells (Darchen and DelageDarchen 1971).…”

-The in vitro rearing of queen bees can improve the management and conservation of pollinator insects. Here, we have developed an in vitro queen-rearing protocol for Plebeia droryana (Apidae, Meliponini). Firstly, we evaluated the amount of food offered naturally to P. droryana queen larvae. After, we grafted P. droryana larvae onto acrylic plates which were kept in constant darkness at 25°C and different relative humidity along larval development. We also compared intertegular distance of P. droryana queens reared in vitro and naturally. We then tested whether queens reared in vitro would be accepted into new colonies with older and/ or callow workers. We found that P. droryana larvae developed into queens if fed with 66 μL of larval food. The survival rate of P. droryana queens was >75 %. The queens reared in vitro are similar in size to naturally produced ones. Finally, colonies only containing callow workers are more likely to accept queens reared in vitro. This queen-rearing technique may improve beekeeping practices in the Neotropical Region.bees / beneficial arthropods / caste determination / crops / pollinators / queen production / virgin queens
