Though their names differ slightly, imidacloprid and acetamiprid are both first-generation neonicotinoid insecticides, belonging to the same class of insecticides. Both are highly effective against piercing-sucking pests, primarily controlling aphids, thrips, and planthoppers. While their range of control is similar, there are several differences.
Imidacloprid and acetamiprid difference 1
There is a significant difference in the speed of insecticidal action. Acetamiprid is a contact insecticide, effective against low-resistance aphids and planthoppers, with rapid kills. Imidacloprid is slower, typically reaching peak mortality within 24 to 48 hours.

There is a significant difference in the duration of action. Acetamiprid has a shorter duration of action, with secondary outbreaks occurring around 5 days after peak infestation, while imidacloprid has a longer duration of action, around 10 days.

Temperature sensitivity differs. Imidacloprid is less affected by temperature, while acetamiprid is significantly affected; the higher the temperature, the better the effect of acetamiprid.
Imidacloprid and acetamiprid difference 4
Their modes of action differ. Imidacloprid's systemic insecticidal effect far surpasses that of acetamiprid, which primarily kills insects through contact. Therefore, in terms of insecticidal speed, acetamiprid is faster than imidacloprid.
