“…In most Ceratina species that have been studied in-depth behaviourally, offspring are guarded by mothers until adulthood (Rehan & Richards, 2010b;Mikát et al, 2016). Benefits of prolonged maternal care include increased offspring survival (Mikát et al, 2016) and feeding of adult offspring by the mother (Lewis & Richards, 2017;Mikát et al, 2017). To date, facultative nest abandonment has only been described in the closely related species C. chalybea (Mikát et al, 2016).…”

“…Previous work has shown that mothers in some Ceratina species continue to feed their adult offspring after reaching adulthood (Sakagami & Maeta, 1977;Lewis & Richards, 2017;Mikát et al, 2017) and that dwarf eldest daughters can perform sibling provisioning in cases of maternal death (Mikát et al, 2017). Specific allocation of food to brood cells by mothers is linked to the provisioning of adult siblings by a sister.…”

“…Mothers usually guard offspring after the completion of brood cell provisioning until offspring reach adulthood (Rehan & Richards, 2010b;Mikát et al, 2016). When offspring develop into adults, mothers feed the adult juveniles pollen and nectar (Sakagami & Maeta, 1977;Lewis & Richards, 2017 ;Mikát et al, 2017) and usually die while feeding the mature offspring (Mikát et al, 2017). Therefore there is no possibility for new reproduction events.…”

“…Therefore there is no possibility for new reproduction events. In some species it has been shown that, if the mother dies, a sister of the young adults can perform provisioning (Lewis & Richards, 2017;Mikát et al, 2017). This helper sister is usually produced in the first brood cell position and is smaller than other females produced in the same nest (Lawson et al, 2016;Mikát et al, 2017).…”

1. Maternal investment can be influenced by several factors, especially maternal quality and possibilities for future reproduction. Mass provisioning Hymenoptera are an excellent group for measuring maternal investment because mothers distribute food sources to each brood cell for each offspring separately. Generally in aculeate Hymenoptera, larger females produce larger offspring and invest more in female offspring than in male offspring. 2. This study investigated patterns of maternal investment in Ceratina chalcites, which has an uncommon type of sexual size dimorphism in Hymenoptera: on average, males are heavier than females. It was found that larger females produce a significantly higher proportion of male offspring, as males are the costlier sex in this species. 3. Facultative nest guarding by females was observed. Females can guard offspring until adulthood, as is typical for bees of genus Ceratina (34.43% of nests); however, in the majority of cases (65.56% of nests), females plug and abandon the nest. Significant differences were found in the amount of investment between guarded and unguarded nests. Guarded nests had a greater number of provisioned brood cells and a higher proportion of male offspring. It is suggested that mothers have two facultative strategies – either she makes a large investment in the offspring of one nest or she abandons the first nest and carries out a second nesting elsewhere.

“…Serotonin, therefore, may play a role in signaling development of ovaries of C. calcarata . However, during the reproductive phase, C. calcarata engages in nest defense (Mikát et al 2017;Rehan et al 2014). Therefore, the increase in serotonin when the female has brood may also be related to nest defense, as serotonin modulates aggressive behavior in other invertebrates (Alekseyenko et al 2014;Huber 2005).…”

Biogenic amines shift during the pre-reproductive to reproductive transition in the small carpenter bee, Ceratina calcarata

The shift from solitary to social living is a major evolutionary transition for social insects. In bees, this transition is marked by certain females becoming reproductive and reducing their role in nest and offspring care, duties that are assumed by other females. Biogenic amines play a significant role in regulating these behaviors in both solitary and social insects. How has the function of biogenic amines in solitary insects been coopted for social behaviors? Here, we used Ceratina calcarata , a behaviorally well-studied small subsocial carpenter bee to explore how biogenic amines may play a role in the reproductive shift over a season. We found that as females transition from a pre-reproductive to reproductive state, ovarian development is accompanied by an increase in brain levels of octopamine and serotonin. For comparison, we provide the first characterization of biogenic amines in the brains of males. These results suggest the essential role of biogenic amines in the transition of reproductive states in a bee on the brink of sociality and provide a deeper understanding of how biogenic amines may have influenced the evolution of social behavior.biogenic amines / reproductive status / octopamine / serotonin / incipiently social Apidologie (2019) 50:90-99
