Insect larvae inhabit the corolla tubes of some Heliconia species (Heliconiaceae). In this study, we present the first evidence of the influence of these larvae on the pollination ecology of Heliconia plants. We provide experimental evidence that the flowers of Heliconia spathocircinata infested by flies have less nectar for pollinators and received fewer visits by hummingbird pollinators, in comparison with uninfested flowers.
Nectar availability in flowers of Heliconia spathocircinata
Availability of nectar in flowers uninfested with dipteran larvae and those infested, with two samples of nectar taken per flower from 70 flowers (at 8 a.m. and 11 a.m., n = 140) of unbagged and bagged inflorescences. In the bagged inflorescences, floral visitors were excluded to prevent the extraction of nectar.
