The beetles that died were unable to avoid or detoxify the chemical and were thus killed by nerve poison insecticides.

  • Chemicals called insecticides are used to kill insects or stop them from acting in an unwanted or destructive way. Their structure and mechanism of operation are used to categorize them.
  • Most insecticides function by interfering with the insect's nervous system. The herbicide prevents neurotransmitters in synapses from transmitting information.
  • Acetylcholine is the name of the substance that the body produces and uses to transmit information through synapses. Muscles can relax because of an enzyme called cholinesterase that binds to acetylcholine.
  • Through the synapses, acetylcholine communicates with the muscles. The cholinesterase is impacted when a pesticide is administered at a deadly dose for a specific body, preventing it from binding with the acetylcholine.
  • The muscles become overstimulated as a result, which will cause paralysis and death.
