Abstract:
... With the advent of imidacloprid and fipronil spot-on treatments and the oral ingestion of lufenuron, the strategies and methods to control cat fleas dramatically changed during the last 25 years. New innovations and new chemistries have highlighted this progress. Control strategies are no longer based on the tripartite approach of treating the pet, the indoor environment, and outdoors. The ability ...

A sustained exposure to even trace residues could be severely harmful if the ingested substance has a long biological half‐life and its toxicity therefore intensifies over time, which is termed time‐reinforced toxicity (TRT). Bumble bees are import ...
