Insecticide Resistance in Mosquitoes
In this video, professor Chuang discusses the issue of insecticide resistance in mosquitoes, which is a significant challenge for vector control programs. The video starts with the methods used to test for insecticide resistance, which includes bioassays to confirm the resistance and evaluate its strength.
Next, he then presents a global survey of insecticide resistance in Aedes aegypti and Aedes albopictus, the two main vectors for dengue, zika, and chikungunya viruses. The survey shows that the resistance to deltamethrin and temephos is severe in Aedes aegypti, especially in Latin America, while Aedes albopictus shows resistance to carbamate, organochlorine, organophosphate, and pyrethroids in Southeast Asia. Professor Chuang emphasizes that these findings are a warning sign and should be used by public health workers and policymakers to modify their control strategies to avoid and reduce the increasing pattern of insecticide resistance.
Review questions:
- What are the methods used to test for insecticide resistance in mosquitoes?
- What are Aedes aegypti and Aedes albopictus?
- What are the main diseases transmitted by Aedes mosquitoes?
- Where is the insecticide resistance to deltamethrin and temephos most severe?
- What should public health workers and policymakers do with the information from the global survey of insecticide resistance in Aedes mosquitoes?
