“…Generally, presence or absence of anthocyanins affects the coloration of the floral display and this is related to flavonoid biosynthetic pathway. In Clematis patens, the anthocyanins for flower color variations have been identified as delphinidin and cyanidin glycosides (14). Later, reports are on the detection of anthocyanin and 4 flavonols from the petals of 3 species of Hibiscus (15).…”

Lepidoptera is an economically important insect pest that attacks many commercially important crops. Synthetic insecticides are currently most extensively utilized to control this pest. The use of massive doses of synthetic pesticides has resulted in resistance and resurgence. Therefore, developing an environmentally acceptable technique for controlling insect pest populations, such as using natural plant components as insecticides, can assist in mitigating the negative impacts of synthetic pesticides. Plant pesticides or botanical insecticides are becoming increasingly popular. This bibliometric research aimed to demonstrate the growth, awareness, importance, international cooperation or collaboration and knowledge gaps in developing synthetic botanical insect pesticides in the future. Information used in this research was culled from 138 scientific papers (Scopus database) and analyzed using VOSviewer 1.6.17. Descriptive statistics was used to identify the rate of botanical insecticide development in controlling these insect pests by analyzing the contributing documents by year, country and bibliometric analysis of country and keyword co-occurrence. The research started in 1985 and exponential growth occurred after 2006. In addition, the trend peaked in 2020 and is currently being maintained. The scientific papers were distributed from 41 countries, with Brazil being the most productive. The bibliographical network shows the relatedness of information about keywords between countries. The results obtained can help recognize existing knowledge gaps that need to be addressed and considered in developing botanical insecticides to control this lepidopteran pest.

“…Monitoring this species potentially assists in assessing ecosystem health and the impact of environmental changes on soil quality (Shyam‐Sundar et al . 2021). Further, E. foetida is often used in eco‐toxicological studies to assess soil contaminants (Ye, Xiong, & Liu 2016).…”

Extracts of botanical origin naturally contain a complex mixture of chemicals considered effective in managing lepidopteran pests. Chemical screening of the ethanolic leaf extracts of two fig tree species, Ficus lyrata and Ficus auriculata, delivered 12 and 15 phyto‐compounds with relatively high peak area percentages in phytol and flavone, respectively. Larvicidal activity against Spodoptera litura yielded higher mortality rates at maximum‐concentration treatment (600 ppm) with Ficus lyrata (91.3%) and Ficus auriculata (98.5%) extracts during the second instar. Sub‐lethal dosages (300 ppm) of both Ficus lyrata and Ficus auriculata extracts impeded the development and reproduction of lepidopteran pests. The enzyme‐inhibition activity of both fig extracts elicited a significant reduction in the major digestive enzymes alkaline phosphatase, acid phosphatase, and lactate dehydrogenase dose‐responsively. Mid‐gut histological screening of Ficus lyrata and Ficus auriculata extracts displayed gut lumen disruptions, shape alterations of columnar cells, and brush‐border membrane damage. Further, the non‐target toxicity of fig extracts against the red worm Eisenia foetida was minimal compared with that of the chemical temephos. Overall, the Ficus extracts proved to be eco‐friendly strategies for managing the polyphagous pest Spodoptera litura and are potentially more sustainable and less harmful to non‐target earthworms. Nonetheless, in silico predictions suggest that the active compounds in fig extracts are predominantly toxic against honeybees (16 compounds) and violate TICE rules (10 compounds). Therefore, the biological actions of fig extracts' individual novel chemistries need to be examined on target and non‐target species to develop better pest management strategies.

“…The epsilon class GSTs of S. litura are good enough to detoxify DDT (dichloro-diphenyl-trichloroethane) and deltamethrin ( Deng et al, 2009 ). Excessive application of cypermethrin and pyrethroid develops resistance in S. litura ( Shyam-Sundar et al, 2021a , 2021b ) by way of decreased penetration, target site sensitivity alteration, and enhancement of detoxification enzyme activity, such as that of cytochrome P450 monooxygenase (P450), carboxylesterase (CarE), and glutathione S-transferase (GST) ( Ahmad and McCaffery, 1999 ; Dong et al, 2016 ). Esterase exhibits a broad spectrum of accuracy, capable of cleaving tri-ester-phosphates, halides, esters, thioesters, amides, and peptides.…”

“…The major damage to agricultural crops results mainly from attack by lepidopteran insects ( Shu, 2012 ; Selin-Rani et al, 2016 ). S. litura , in particular, develops resistance when exposed to synthetic pesticides ( Jahan et al, 2008 ; Shyam-Sundar et al, 2021a , 2021b ). The present study is aimed at finding the strategy of using allelochemicals for developing resistance when exposed to insecticides.…”

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.
