“…The severity of yield loss caused by S. litura can vary based on several aspects, including the stage of plant development, crop species, and pest population density. In severe situations, yield loss might reach as high as 50 percent or more, inflicting significant financial damage on farmers [2,3].…”

Spodoptera litura poses a threat to important crops in Indonesia, leading to productivity failure and economic repercussions. Botanical insecticides have garnered attention in crop cultivation due to their easy applicability and effectiveness against specific pests. In this study, the effectiveness of majapahit (Crescentia cujete), a popular medicinal plant, in reducing S. litura infestation was investigated through in planta test using Chinese mustard (Brassica chinensis var. parachinensis). The experiment followed a completely randomized design (CRD) with four treatments of C. cujete fruit extract at concentrations of 0, 20, 40, 60, and 80%, each replicated four times. Parameters observed in this study included the growth profile of mustard plants (plant height, number of plants, fresh weight), leaf damage index (LDI), and mortality after application for 30 days after planting. Results revealed a significant concentration-response relationship for both the LDI values and mortality rates. The determination of LC50 for C. cujete fruit extract yielded a value of 29%. The use of C. cujete as an insecticidal agent warrants promotion, and further investigation with a larger sample population and different target crops is necessary in the future.

“…To control S. litura , a variety of techniques have been used in India and worldwide, including cultural, physical, botanical, biological and chemical control methods (Alivelu & Duraimurugan, 2018; Baker et al, 2020; Sharma et al, 2022; Tiwari et al, 2020). Among these chemical control is one of the most widely used method to control the pests.…”

Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae) is a polyphagous pest causing economic losses to a number of agricultural crops. The present study was conducted to explore the insecticidal potential of some soil bacteria against S. litura. Among the tested bacterial isolates, Shewanella sp. (SS4) and Thauera sp. (M9) caused higher larval mortality. Concentration–response bioassays indicated a dose‐dependent increase in larval mortality with maximum mortality of 80 and 76%, respectively, due to Shewanella sp. and Thauera sp. Both the bacteria negatively affected the growth and development, reduced adult emergence and induced morphological deformities in adults. Nutritional parameters of S. litura i.e. relative growth and consumption rate, efficiency of conversion of ingested and digested food as well as approximate digestibility of food decreased with increasing bacterial concentrations. Histopathological studies revealed the disruption of peritrophic membrane and midgut epithelium of larvae. Profiles of digestive enzymes i.e. α‐amylases, α, β‐glucosidases and galactosidases, lipases and proteases were also significantly decreased with bacterial treatment. Comet assay test indicated DNA damage in larval haemocytes due to bacterial infection. These results imply that both these bacterial isolates have the potential as biological control agents and may prove as environmentally friendly alternative for pest management techniques.

“…The larval feeding activities result in considerable economic losses for farmers, and the severity of these losses varies based on factors such as plant growth stage, crop type, and pest population density. In severe cases, yield losses can exceed 50%, leading to significant financial setbacks for farmers (Natikar and Balikai, 2015;Sharma et al, 2022).…”

The Spodoptera litura (Tobacco Caterpillar) has significantly damaged various cultivated crops, primarily affecting Solanaceous crops. It voraciously consumes the crop leaves, giving the appearance of animal grazing. It can cause extensive damage in its later stages, ultimately leading to crops decay. Commercial farmers typically depend on chemical pesticides for control. However, the overreliance on chemical insecticides to combat S. litura has led to the development of resistance over time. Various strategies have been explored in pursuit of environmentally friendly pest control measures. These include natural predators, employing techniques like sex pheromones and genetically modified crops, and utilizing RNA interference tools. While these methods have encountered implementation challenges, they are noteworthy for being safe, sustainable, and tailored to specific species. In this comprehensive review, we have delved into historical and current practices for pest management, covering cultural techniques, chemical controls, and biological methods. In addition, we have examined emerging technologies like the gene editing approach, nano-insecticides, neuropeptides and seminal fluid proteins that are promising tools in the ongoing efforts to manage S. litura.
