Cleo Cervancia is a Professor Emeritus from the University of the Philippines Los Baños. She is actively involved in bee research and extension with focus on native bee species, especially stingless bees. Among the beekeeping technologies she developed, together with her team, are the Propagation of Stingless Bees, Tetragonula biroi in the Philippines, Utilization of Stingless Bees for Pollination, Harvesting Techniques for Wild Honey and Bee Product Processing and Development. She led the formulation of Standards for Tropical Honey and the crafting of Standards for Stingless Bee Honey. To her credit are 73 publications in refereed journals,  seven chapters in a book, 3  co-authored books, 5 technical bulletins, and numerous paper presentations at conferences. She is a respected scientist, holding key positions such as President of Apimondia (International Federation of Beekeepers’ Association) Regional Commission for Asia from 2011-2022, Vice President of Asian Apicultural Association and Member of the Apimondia Scientific Commission on Bee Flora and Pollination and Bee Health.

Analysis of Plant-Pollinator Interaction Using Mathematical Models

Abstract

Bees and other pollinators increase ecosystem biodiversity through pollination of wild and cultivated crops.  This paper highlights the pollination of selected crops like mango, pepper, eggplant, and passionfruit and the foraging behavior of their corresponding pollinators. It also documented the pollinator restoration in Maliwaliw island, Eastern Samar which was hit by typhoon Haiyan showing the impact of pollinator loss on food security. It was demonstrated that the pollinators and plants should attain a certain population density to effect pollination, as shown in May’s model of mutually interacting populations. Depletion of forage resources is a major reason for the pollinator population decline, indicating the impact of competition among the pollinator species. This is the reason why pollinator pasture development is necessary for sustainable pollination services. Each environment has a carrying capacity, as shown in the logistic growth model. The implication of these models on the management and conservation of pollinator species is discussed in this paper.
