Bart - Insecticides Flashcards
What is the primary way insecticides are classified in the industry?
Insecticides are classified by their Mode of Action (MoA) and the system they target, such as respiration, development, or neurons.
How does \textit{Bacillus thuringiensis} (Bt) Cry protein target insect gut cells?
Bt Cry protein binds to specific receptors in the insect midgut, forming pores that cause cell lysis.
What is the Mode of Action of Rotenone in the electron transport chain?
Rotenone blocks Complex I of the electron transport chain, halting ATP production and leading to cellular energy depletion.
How does Diflubenzuron affect insect development?
Diflubenzuron inhibits chitin synthesis, preventing proper exoskeleton formation during molting.
What organ system does Flonicamid primarily target, and how?
Flonicamid targets neuronal function, specifically the iav1 channel in mechanotransduction, disrupting sensory signals.
What role do scolopidial cells play in insect hearing?
Scolopidial cells are mechanosensitive cells involved in detecting sound and proprioception in insects.
How does Flonicamid affect the femoral chordotonal organ (fCO) in locusts?
Flonicamid induces continuous hindleg extension by stimulating the femoral chordotonal organ (fCO) in locusts.
Why does Flonicamid have little to no effect on iav1 mutants?
Flonicamid has no effect on iav1 mutants because they lack the iav1 channel, the likely target of Flonicamid.
How is calcium imaging used to study scolopidial cell activity in response to Flonicamid?
Calcium imaging with GCamp6 allows visualization of scolopidial cell activity, which increases when Flonicamid is applied.
How does Flonicamid influence auditory amplification in Drosophila?
Flonicamid disrupts the active amplification of low sound velocities in wildtype Drosophila, but has no effect on amplification in iav1 mutants.
