What is the Difference Between Malathion and Parathion?

The main difference between malathion and parathion lies in their toxicity and effects on organisms. Both malathion and parathion are insecticides used for agricultural purposes, but they have different levels of toxicity and potency:

• Malathion: Less toxic than parathion, with an acute oral toxicity to mammals of 1400 mg/kg. It is still widely used as an insecticide for agricultural purposes. At lower doses, malathion has been shown to induce insulin resistance biomarkers and reduce insulin sensitivity.
• Parathion: More toxic than malathion, with an acute oral toxicity of 3–6 mg/kg (classified as class I by the WHO). It is considered the most toxic insecticide and has the strongest effects. Parathion is no longer in use as it is banned in many countries due to its high toxicity. Neonatal parathion exposure in rats has been found to alter lipid metabolism and induce inflammation.

In summary, malathion is less toxic and has lower effects compared to parathion, which is the most toxic insecticide and has the strongest effects. While malathion is still in use, parathion has been banned in many countries due to its high toxicity.

Comparative Table: Malathion vs Parathion

Malathion and parathion are both toxic insecticides used for agricultural purposes, but they differ in their toxicity and effects on insects and animals. Here is a table summarizing the differences between malathion and parathion:

Malathion is less toxic compared to parathion and has fewer side effects. It is still in use as an insecticide, while parathion has been phased out due to its high toxicity and strong effects. Both insecticides are toxic substances and can harm or affect the biological cycles in nature.
