The potency of chemical insecticides in management of cutworm, Agrotis ipsilon Hufnagel (Noctuidae: Lepidoptera): A review

Abstract

The black cutworm, Agrotis ipsilon (Lepidoptera: Noctuidae), is ubiquitous in many countries around the globe. It is one of the most aggressive underground insect species which feeds on more than 100 host crops. The traditional control methods for this species were not considered promising. Therefore we can develop a good management framework by incorporation of chemical control for the reduction of this pest. Some pesticidal groups viz., synthetic pyrethroids, carbamates, organophosphates and neonicotinoids etc., were used primarily to protect crops from cutworms. However, in case of injudicious use, these chemicals may have a detrimental impact on human health and natural environment. In addition to this, frequent use of the same chemicals may cause insect resistance to particular insecticides. The effects of such compounds should be monitored to avoid the occurrence of harmful impacts of insecticides on the surroundings. Thus, this review discusses the efficacy, sub-lethal impact and corrects methods of applying different chemicals as an essential part of integrated management (IPM) of cutworm.
