“…According to Tarikul Islam et al [14], high polyphenol oxidase activity in the haemolymph caused larvae to develop more slowly and reduced integument resistance of larvae fed on Si-supplemented plants may have contributed to their vulnerability to natural enemies. The effects of different silicon sources on field crop herbivores and their mechanisms for transferring tolerance to crops were reviewed by Murali Baskaran et al [6].…”

“…The trichome undergoes changes as part of the Si-induced defence system [5]. Si accumulates in plant cell walls, activating the intrinsic chemical defences of the plant, including volatile and non-volatile chemicals as well as other physical structures like trichomes, which provide protection by increasing the production of lignin and phenolic compounds were reviewed by Murali Baskaran et al [6].…”

In the Virudhunagar district's Thoppur village from rabi 2021–22, a field trial was carried out to examine the impact of silicon sources and growth regulator on the harm caused by maize fall armyworm (Spodoptera frugiperda). Basal soil application of calcium silicate at six different doses and foliar applications of silicic acid, gibberellic acid and potassium silicate in maize crop revealed that basal application of 150 kg of calcium silicate/ha + 0.2% silicic acid @ 15 DAS + 50 ppm GA @ 30 DAS was found to be effective in reducing leaf damage (42.88% per plant), whorl damage (36.05% per plot) and cob damage (26.92% per plot), followed by treatment with 75 kg of calcium silicate/ha + 0.2% silicic acid @ 15 DAS + 50 ppm GA @ 30 DAS with leaf, whorl and cob damage of 44.74% per plant, 39.24% per plot and 26.92% per plot respectively. The treatment with a basal application of 150 kg of calcium silicate/ha + 0.2% SA @ 15 DAS + 50 ppm GA @ 30 DAS produced the highest yield (7, 287 kg/ha), which was followed by the treatment with 75 kg of calcium silicate + 0.2% SA @ 15 DAS + 50 ppm GA @ 30 DAS (7, 092 kg/ha). As a result, in the current research, the basal application of calcium silicate 150 kg/ha along with foliar application of silicic acid (0.2%) and gibberellic acid (50 ppm) at 15 and 30 DAS decreased the level of leaf, whorl, and cob damage caused by fall armyworm on maize at the field condition.

“…In line with the findings of Carlos A. C. Crusciol [17], Si application via soil in potato plants can elevate Si concentration in leaves. Elevated silica levels within plant leaves can engender increased resistance against herbivorous insects, such as Spodoptera [18]. This fortification arises from the accumulation of silicon in plant cell walls, leading to enhanced synthesis of lignin and phenolic compounds.…”

The Beet Armyworm (Spodoptera exigua) is a polyphagous defoliator that poses a significant threat to cultivated plants, particularly shallot crops. Its attacks during the vegetative phase cause substantial damage. To control this pest, farmers often resort to synthetic pesticides, leading to negative consequences such as resistance development. To address consequences, internal control measures, like enhancing plant resistance through beneficial nutrients like silica, are crucial. Silica has been known to improve plant resistance against pest attacks. This study aims to investigate the effects of various methods of applying nano-sized rice husk ash fertilizer on the growth and resistance of Biru Lancor cultivar of shallots against S. exigua. Nano-rice husk ash fertilizer with an average particle size of 65,326 nm was produced and applied using three methods: placement, foliar, and seed coating. The results demonstrated that all methods of nano-rice husk ash application increased plant resistance, reducing leaf damage and pest mortality. The foliar application yielded the best results, enhancing plant height and epidermal cell wall thickness. Furthermore, nano-rice husk ash application positively influenced shallot productivity. This study highlights the potential of nano-sized rice husk ash as a sustainable and effective internal control measure against S. exigua, complementing synthetic pesticides for shallot pest management.

“…Pest control practices via indiscriminate application of synthetic insecticides lead to resistance development and hence the failure of the control measure ( Murali-Baskaran et al, 2021 ; Subaharan et al, 2021 ). Resistance to insecticides in lepidopteran pests is mainly by detoxification and target site insensitivity, involving enzymes such as esterase, glutathione complex, and cytochrome P450 ( Tang et al, 2022 ).…”

Spodoptera litura (Fabricius) is an agriculturally significant polyphagous insect pest that has evolved a high level of resistance to conventional insecticides. A dietary assay was used in this work to assess the resilience of field populations of S. litura to λ-cyhalothrin. Analysis of the function and expression of the cytochrome P450 gene was used to test the sensitivity of S. litura larvae to sub-lethal concentrations of the insecticidal plant chemical Precocene 1, both by itself and in combination with λ-cyhalothrin. The activity of esterase enzymes (α and β) was found to decrease 48 h post treatment with Precocene 1. The activity of GST enzyme and cytochrome P450 increased with Precocene 1 treatment post 48 h, however. Expression studies revealed the modulation by Precocene 1 of cytochrome P450 genes, CYP4M16, CYP4M15, CYP4S8V4, CYP4G31, and CYP4L10. While CYP4M16 expression was stimulated the most by the synergistic Precocene 1 + λ–cyhalothrin treatment, expression of CYP4G31 was the most down-regulated by Precocene 1 exposure. Hence, it is evident that λ–cyhalothrin-resistant pest populations are still sensitive to Precocene 1 at a sublethal concentration that is nevertheless capable of hindering their development. Precocene 1 can therefore be considered a potent candidate for the effective management of insecticide-resilient S. litura.
