Indoxacarb is an oxadiazine pesticide developed by DuPont that acts against lepidopteran larvae. [1] It is marketed under the names Indoxacarb Technical Insecticide, Steward Insecticide and Avaunt Insecticide. It is also used as the active ingredient in the Syngenta line of commercial pesticides: Advion and Arilon. [2] [3] [4]

Contents

Its main mode of action is via blocking of neuronal sodium channels, belonging to IRAC group 22A. [1] It is fairly lipophilic with a Kow of 4.65. This pesticide should be used with caution since some insects such as the oriental tobacco budworm (Helicoverpa assulta) become resistant when exposed. [5]

In 2021, the European Union [6] chose not to renew Indoxacarb for use as a plant-protection insecticide. The United Kingdom still allows use of the compound until 2025. [7]

Development

Indoxacarb was developed by the McCann et al. team at E. I. du Pont de Nemours. [8] [9]

Household products

Indoxacarb is the active ingredient in a number of household insecticides, including cockroach and ant baits, and can remain active after digestion. [10] In 2012 DuPont's Professional Products including the line of Advion and Arilon products was purchased by Syngenta. [11] Indoxacarb is the active ingredient in the pet product, Activyl, from Merck Animal Health. It is marketed to kill fleas on dogs and cats. [12]

Toxicity to humans

While toxicity to humans has not been formally studied, there is a reported case of a person consuming indoxacarb in a suicide attempt. [13] The patient developed methemoglobinemia following ingestion. [13] Methemoglobinemia (also known as blue baby syndrome) is a condition which ultimately decreases the effectiveness of red blood cells to exchange oxygen with organs. Methemoglobinemia can be fatal if left untreated, however when the cause is exposure to a chemical agent (not genetic) a variety of treatments are available and effective. [14] [15]
