“…In fact, the increased use of plants with this technology may have increased the number of outbreaks of this invasive species in crops around the world (Montezano et al 2018 ), which makes the prospecting of new biocontrol agents to manage this insect more urgent. From this perspective, the use of nucleopolyhedroviruses has recently emerged as an important tool to control Spodoptera populations and reduce resistance issues (Sajid et al 2021 ).…”

Increased attention is being focused on the biological control of agricultural pests using microorganisms, owing to their potential as a viable substitute for chemical control methods. Insect cadavers constitute a potential source of entomopathogenic microorganisms. We tested whether bacteria and fungi isolated from Spodoptera frugiperda (JE Smith) cadavers could affect its survival, development, egg-laying pattern, and hatchability, as well as induce mortality in Anthonomus grandis Boheman adults. We isolated the bacteria Enterobacter hormaechei and Serratia marcescens and the fungi Scopulariopsis sp. and Aspergillus nomiae from fall armyworm cadavers and the pest insects were subjected to an artificial diet enriched with bacteria cells or fungal spores to be tested, in the case of S. frugiperda, and only fungal spores in the case of A. grandis. Enterobacter hormaechei and A. nomiae were pathogenic to S. frugiperda, affecting the survival of adults and pupae. The fungus Scopulariopsis sp. does not affect the survival of S. frugiperda caterpillars and pupae; however, due to late action, moths and eggs may be affected. Aspergillus nomiae also increased mortality of A. grandis adults, as well as the development of S. frugiperda in the early stages of exposure to the diet, as indicated by the vertical spore transfer to offspring and low hatchability. Enterobacter hormaechei and A. nomiae are potential biocontrol agents for these pests, and warrant further investigation from a toxicological point of view and subsequently in field tests involving formulations that could improve agricultural sustainability practices.

“…It is challenging to control this pest in the fields due to the lack of S. litura resistance in host plants and inadequate control techniques. Various plant products have been investigated against S. litura, and many researchers have reported some promising plants (Sajid et al, 2021). However, testing of plant extracts against this insect is still ongoing globally to determine the various effects of botanicals on this pest and to develop a cost-effective and environmentally friendly biopesticide.…”

Numerous cultivated plants are attacked by Spodoptera litura, which also significantly reduces crop yields. In this study, a green strategy was used to assess the toxicological impact of three plant extracts (Eucalyptus globulus, Allium sativum, and Azadirachta indica) against S. litura larvae in their second and third instars. The study resulted that among the tested extracts, neem (A. indica) was found to be the most toxic and efficient extract followed by E. globulus and A. sativum. 29.92, 56.61, and 79.53% mortality of 2nd instar larvae were recorded at 3, 5, and 7 ppm, respectively, while 24.52, 27.66, and 72.42% of 3rd instars. Among the tested extracts, A. sativum was the least toxic extract than others. One of the main causes of large losses in field crops is insect pest damage. According to the study’s findings, A. indica extract has the potential to lessen S. litura damage to crops as a natural substitute for chemical pesticides without harming beneficial species.
