Hence, a series of laboratory choice and paired-choice tests were conducted at Agriculture and Forestry University in May 2021 to evaluate the host plant preference by the fall armyworm. Alternative management strategies should be developed by understanding pest biology and ecology. However, these practices are not sustainable and are linked to the environment, biodiversity and farmers' health. Insecticides are considered an important tool of FAW management as well as other lepidopteran maize pests. Larvae are very numerous and disperse in large numbers and behave like ‘armyworm’. Fall armyworm has six larval stages, the first three stages are less voracious compared to the latter stages. But most frequently consumed crops are field corn, sweet corn, wheat, sorghum, sugarcane, Bermuda grass etc. Fall armyworm feeds a wide range of crops and non-crops including weeds, with over 353 plant species. Nowadays, maize production is threatened by one invasive pest, the fall armyworm ( Spodoptera frugiperda) particularly in Africa and Asia, and threatens millions of poor people. Maize is the most important cereal crop after rice and wheat in Asia.
