Organocarbamate Insecticide Identification

An organocarbamate insecticide is a type of pesticide derived from carbamic acid. These chemicals work by inhibiting the enzyme acetylcholinesterase, which is crucial for nerve function in insects.

Insecticide Chemical Classifications

To identify the organocarbamate insecticide among the options, we need to classify each compound:

• Parathion: This is an organophosphate insecticide.
• Chlorpyrifos: This is also an organophosphate insecticide.
• Aldicarb: This is classified as an organocarbamate (specifically, an N-methyl carbamate) insecticide. It is a systemic pesticide.
• Malathion: This is another common organophosphate insecticide.

Conclusion

Based on the chemical classification, Aldicarb is the only organocarbamate insecticide listed.
