Actividad de los polinizadores en la fecundación de la flor de cacao (Theobroma cacao) bajo tres sistemas de producción en Portoviejo- Manabí

The objective of this research was to evaluate the activity of pollinators on the fertilization of the cocoa flower (Thebroma cacao) in various production systems. This project was carried out at INIAP's Portoviejo experimental station. Pollinating species of the Ceratopogonidae family collected in yellow viscous traps of 5 x 5 cm distributed in three production systems were identified and counted, the same pollinating species of Ceratopogonidae were reported in the three production systems, among which the genera stand out. Forcipomyia and Dasyhelea. The role of pollinators in the fertilization of the cocoa flower was demonstrated through pollination techniques (free / natural and assisted). The sleeve technique was used as a control. It was started with a known number of flowers / branches, from days 3, 6, 14 and 21, to determine the number of active flowers, pollinated, fertilized and fruits formed, the assisted pollination technique is significantly better than the technique of free or natural pollination. It can be concluded that the systems studied do not relate the percentage of pollination, fertilization and fruit formation, however, the Monoculture system is the most optimal because it was where the highest number of pollinated flowers (D-6) and fertilized (D- 14) and formed fruits (D-21 and D-36).
