“…The reduction in larval weight might be partly due to the increased levels of the PPO, POD activities, phenolics and other compounds, on account of insect attack. Alteration in digestibility and palatability of plant tissues by the induced compounds in response to insect attack affect insect growth and development adversely (Sharma et al 2005a, b;Chen et al 2009;Bhonwong et al 2009;Senthil-Nathan et al 2009;War et al 2011a, b).…”

Three groundnut germplasm lines, ICGV86699 (resistant), NCAC 343 (resistant) and TMV 2 (susceptible), were examined for Spodoptera litura (Fab.) resistance. Biochemical parameters such as oxidative enzyme activities, peroxidase (POD) and polyphenol oxidase (PPO), other defensive components such as total phenols, hydrogen peroxide (H 2 O 2 ), malondialdehyde (MDA) and protein contents were evaluated in these germplasm lines after 24, 48, 72 and 96 h following S. litura infestation to characterize the mechanism of resistance. Enzyme activities and total phenols, H 2 O 2 , MDA and protein contents were increased following infestation; however, significance varied at different time intervals and among germplasm lines depending upon the induced level of resistance. The three germplasm lines differed in resistance mechanisms to S. litura and the resistance may be partly due to higher enzyme activities, and other components studied. Among the three germplasms tested, ICGV86699 showed greater elevation in POD and PPO activities and in phenolic and H 2 O 2 contents at different time intervals as compared to NCAC 343 and TMV 2.

“…Many botanical insecticides and extracts affect insect metabolism by inhibiting or stimulating the activity of digestive enzymes (Napoleao et al., ; Senthil‐Nathan, , ; Senthil‐Nathan, Kalaivani, Choi, & Paik, ; Senthil‐Nathan, Kalaivani, Murugan, & Chung, ; Senthil‐Nathan et al., ). Our results show the leaf extracts have antifeedant and toxic effects on Spodoptera littoralis larvae (Sadek, ).…”

Extracts from Justicia adhatoda L. (Acanthaceae) strongly reduced the fitness of the mosquito, Aedes aegypti Linn. The methanolic extracts inhibited several enzymes responsible for protecting insects from oxidative and other damage, including glutathione-S-transferase, superoxide dismutase, cytochrome P450, and α- and β-esterases. They increased repellency (maximum repellency at 100 ppm) in host-seeking adult females using the "arm-in cage assay." Histopathological examination showed the extracts led to serious midgut cell damage. Justicia adhatoda extracts led to reduced fecundity and oviposition of gravid females compared to controls. The extracts led to substantially reduced A. aegypti survival. We infer that the extracts have potential to reduce pathogen transmission by suppressing population growth of A. aegypti, and possibly other mosquito species.
