Do Classical Methods of Assessing Exposure in Bees are Effective for Ecotoxicology Diagnosis?
“While some relatively reliable methods have been developed for diagnosing some of these mechanisms (e.g., insect resistance to some pesticides), methods to measure precisely biological responses to exposure need to be improved.”
State of Art of Morphological Biomarkers in Ecotoxicology Researches on Bees
“(1) Direct determination of xenobiotics at the level of cells and organs;(2) Qualitative and quantitative biochemical changes in some low- molecular and high-molecular substances; (3) Genetic changes at individual and population levels as indicators of exposure; and – (4) Effects of xenobiotics at the population level.”

Could be not the answer for a Silent Damage!Could be not the answer for a Slow Damage Process!
Could be not the answer for Secondary Damage Effect!
