Review

Acetamiprid is a natural product found in Streptomyces canus (Nouioui et al. 2018), a species of bacterium and, in synthetic form, commercially available as an insecticide. 

It appears in the form of a white powder stable to hydrolysis, in water it undergoes slow photodegradation.

What it is used for and where

First-generation broad-spectrum neonicotinoid insecticide, nicotinic acetylcholine receptor of insects used to control aphids on vegetables and fruit. It appeared on the market in 1980, gained notoriety for its low toxicity and was used worldwide as an active ingredient for pest control.  Most neonicotinoids act as systemic pesticides while the application of Acetamiprid is directly on foliage. The warning is not to apply it during flowering as bumblebees and other pollinating insects may take it up through nectar or pollen. Another important warning is not to take the fruit of the tree on whose leaves Acetamiprid was sprayed for at least 14 days after spraying.

The intensive use of insecticides has developed resistance against insecticides in general. This study provides information on the management of resistance development in field populations of certain aphids (1). The best results in combating aphids by Acetamiprid were found on aphids in apples, cucumbers, tobacco and citrus fruit as the effect of Acetamiprid effectively combats pests that show resistance to pyrethroid, carbamate and organophosphorus pesticides. Furthermore, Acetamiprid, although belonging to the same series as the insecticide Imidacloprid, has a broader spectrum of action.

Safety

It is considered a safe insecticide, some studies have found some toxicity, but the data remain contradictory (2). Acetamiprid has not been recognised as persistent in soil and its degradation is exhausted in about 43 days (3).
