“…The stress markers (protein carbonyl, lipid peroxide and hydrogen peroxide content) increased notably with extended feeding indicating a certain deterioration of insect tissues. An increase in oxidative stress has also been reported in daidzein fed S. litura larvae [ 62 ]. Barbehenn et al [ 63 ] reported that increased oxidative stress in the gut wall of M. disstria was linked with enhanced phenolic oxidation.…”

“…To investigate the effect of bacteria on nutritional physiology of S. litura , second‐instar (6 days old) larvae were randomly selected and the experiment was conducted as per protocol of Farrar et al (1989) and Punia and Chauhan (2022). The larvae starved for 3–4 h weighed individually and released into rearing tubes (4 cm × 6 cm) containing weighed air‐dried castor leaves saturated with the above‐mentioned bacterial concentrations of each isolate.…”

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.

“…Larvae fed on flavonoids suggested the induction of oxidative stress due to an increase or decrease in detoxifying enzyme activities. For instance, Punia and Chauhan [ 63 ] observed that S. litura larvae treated with daidzein presented significantly higher enzymatic activities of superoxide dismutase, catalase, ascorbate peroxidase, and glutathione S-transferase, indicating oxidative stress and the need to metabolize daidzein. The authors also verified an increase in oxidative stress markers, namely hydrogen peroxide, lipid peroxide, and protein carbonyl.…”

“…However, esterase activity was significantly lower in the assays performed with 1000 ppm of catechin than at 500 ppm. These biochemical alterations could interfere with food uptake by larvae because the energy used to digest food could be transferred to detoxify these flavonoids [ 63 ]. On the other hand, the inhibition of these enzymes could result in greater toxicity to the organism.…”

Pesticide overuse in agricultural systems has resulted in the development of pest resistance, the impoverishment of soil microbiota, water pollution, and several human health issues. Nonetheless, farmers still depend heavily on these agrochemicals for economically viable production, given the high frequency at which crops are affected by pests. Phytopathogenic insects are considered the most destructive pests on crops. Botanical pesticides have gained attention as potential biopesticides and complements to traditional pesticides, owing to their biodegradability and low toxicity. Plant-based extracts are abundant in a wide variety of bioactive compounds, such as flavonoids, a class of polyphenols that have been extensively studied for this purpose because of their involvement in plant defense responses. The present review offers a comprehensive review of current research on the potential of flavonoids as insecticides for crop protection, addressing the modes and possible mechanisms of action underlying their bioactivity. The structure–activity relationship is also discussed. It also addresses challenges associated with their application in pest and disease management and suggests alternatives to overcome these issues.
