About The Author

Francisco Javier Espinosa García is an ecologist specialized in chemical ecology and the ecology of invasive plants and weeds. In chemical ecology, it has made significant contributions in the description and understanding of the function of the diversity of plant secondary metabolites in the defense of plants, which are potentially useful in biological control and in the management of agroecosystems to reduce the use of pesticides In the area of weeds and invasive plants, he has produced manuals, catalogs and scientific articles widely used by colleagues, government entities, and students of agronomy and biology. It has also collaborated with the preparation and revision of the Official Standards "NOM-043-FITO-1999, specifications to prevent the introduction of quarantine weeds to Mexico" and "Project to modify the Official Mexican Standard proy-mod-nom-028- phyto-1995 establishing the requirements for the importation of grains and seeds, except for sowing. " He also participated in the elaboration of the National Strategy of Invasive Species and has contributed in the evaluation of criteria for risk analysis for introduced plant species.


Are All Clonal Crops Equally Vulnerable To Insect Pest Attacks? The Avocado File

In wild populations, most plant species exhibit high genetic diversity, which often is manifested as high chemical diversity and variation. This chemical heterogeneity is very important in plant populations to resist insect and pathogen attack. However, in monoculture crops, where chemical diversity in quality and quantity is low, possibilities to resist pest attack and diseases are diminished. It is common knowledge that genetic uniformity in annual crops leads to disastrous pest and/or pathogen attack. An emblematic example of this phenomenon...
