As the demand for guayusa grows in the United States, Runa continues to research its cultivation in Ecuador so that it may continue to produce high quality guayusa with hundreds of small farmers. One of the most fascinating parts of our work is that we’re creating a new and sustainable production model for a previously unmanaged plant, a process which requires serious research protocols.
With a degree in Forestry Management from the Escuela Superior de Politécnica de Chimborazo, Runa’s principle investigator is Ms. Adriana Mariño. Adriana laughs that she recognizes there are more profitable ways to use her advanced degree, but for whatever reason she loves investigating insects! Previously Adriana has worked for some of the leading international reforestation organizations like PROFAFOR, and brings deep experience to Runa.
For the last seven months she has worked day and night (no joke, she rivals Tyler for hours worked during the late night shift in the Archidona office) to investigate Integrated Pest Management solutions for guayusa in a variety of agroforestry settings. Below you can learn how Adriana’s research embodies Runa’s holistic approach to development and ecosystem conservation.
What data are you collecting for Runa?
The goal of my research is three fold. I am cataloguing the insects endemic to guayusa’s ecosystem, identifying which of these pests are potentially dangerous to the longevity of the tree and creating an integrated pest management plan to combat the insects found to be harmful.
What threatens the health of a guayusa plant?
If you grow guayusa in a monoculture, the practice of growing exclusively one species of plant on a plot of land, you will create an environment in which the harmful insects to guayusa will increase their numbers until they destroy the cultivation because it lacks the beneficial insects to maintain the natural balance. This in turn will provoke economical losses to the farmer who invested in this plot. It is important for the production of guayusa that it is planted amongst other species. A mixed plantation favors the increase of beneficial insects thus reducing the density of harmful pests specific to any particular species.
What is the difference between dealing with guayusa organically and using Integrated Pest Management?
When you deal with a pest problem organically, you apply organic products directly to the plant. On the other hand, Integrated Pest Management systems look at the ecosystem holistically and tries to manage, in a comprehensive way, the beneficial and harmful insects to create a balance and avoid problems. For example, if an area is being adversely affected by caterpillars, one could introduce a species of insect that repels caterpillars.
How is Runa applying what you’ve learned?
I have shared my research with Runa’s local field staff so they can look out for the harmful insects that I have discovered. The field staff help me by collecting specimens and describing guayusa-related insects and their behavior. With this information I can better identify which insects are harmful and which are helpful. Once I have collected all of the data, I will integrate it into my plan and create a guide to help the staff identify and solve pest problems on their own.
