Dr. Alberto Barrion is recognized for his outstanding contributions to insect and spider biology and taxonomy of rice and rice-based crops. These contributions have benefited programs in the integrated pest management, biocontrol, community ecology and pest modelling. His pioneering works on the “Taxonomy and Bionomics of Philippine Riceland Spiders-Potential Biocontrol Agents of Rice Pests”, “Rice Leaffolder Complex of the Philippines” and “Food Webs of Rice Agroeco-systems” have stimulated further understanding of the rice-pest-natural enemy relationship.
