Nesting and reproductive habits of the solitary bee Centris analis in trap nests under a tropical climate

Resumen

Pollination is a key factor in global agricultural production, and there is a need to increase the number of bee species that can be bred for pollination in agriculture, such as the oil-collecting solitary bee Centris (Heterocentris) analis (Fabricius, 1804). In this study, the nesting and reproductive behavior of the bee were studied under tropical conditions, with the aim of producing information for breeding and using C. analis for crop pollination. The study was conducted from May to October 2017, using trap nests and daily observations from 5.00 a.m. to 6.00 p.m. of nest occupation and building, foraging trips in the field and interactions between individuals and kleptoparasites. The results showed that the bees easily colonize and nest in trap nests for an extended period of the year under tropical conditions, and that the use of this type of nest makes it possible to multiply populations of this species for their potential use in crop pollination. However, sources of floral oil and the availability of nesting sites have both proved to be limiting factors to population growth in this species on bee farms.
