1 ABOUT SOME THRIPS SPECIES ASSEMBLAGES FOUND IN AVOCADO TREES (Persea americana Mill) IN MEXICO

Contrary to what is found in countries like the United States of America (California), Israel and South Africa, where only one or two thrips species have an economic impact on avocado trees, Mexico has 33 species of phytosanitary concern, 10 predators and 42 visitors. What is very remarkable in avocado damaging species, is that many of them can be assembled in the same tree, which means one pest species is rarely acting isolated, like Frankliniella brunneri Watson (at Uruapan, Michoacán). Assemblages found in several localities of the Volcanic Range of Mexico, in the states of Mexico and Michoacán were considered in this study, as follows: I
