“…Prolonged larval and total developmental period of S. litura larvae was also noticed. Inability of S. litura larvae to develop on artificial diet containing phenolic rich extracts of red gram ( Cajanus cajan L.) and Acacia nilotica (L.) has been reported by Bhattacharya and Chenchiah 24 and by Gautam et al 25 , respectively. Gallic acid, hydrolysable tannin can interact with metal ions and macromolecules such as polysaccharides.…”

The antibiosis effect of gallic acid on Spodoptera litura F. (Lepidoptera: Noctuidae) and its parasitoid evaluated by feeding six days old larvae on artificial diet incorporated with different concentrations (5 ppm, 25 ppm, 125 ppm, 625 ppm, 3125 ppm) of the phenolic compound revealed higher concentration (LC50) of gallic acid had a negative impact on the survival and physiology of S. litura and its parasitoid Bracon hebetor (Say) (Hymenoptera:Braconidae). The mortality of S. litura larvae was increased whereas adult emergence declined with increasing concentration of gallic acid. The developmental period was delayed significantly and all the nutritional indices were reduced significantly with increase in concentration. Higher concentration (LC50) of gallic acid adversely affected egg hatching, larval mortality, adult emergence and total development period of B. hebetor. At lower concentration (LC30) the effect on B. hebetor adults and larvae was non-significant with respect to control. Gene expression for the enzymes viz., Superoxide dismutase, Glutathione peroxidase, Peroxidase, Esterases and Glutathione S transferases increased while the total hemocyte count of S. litura larvae decreased with treatment. Our findings suggest that gallic acid even at lower concentration (LC30) can impair the growth of S. litura larvae without causing any significant harm to its parasitoid B. hebetor and has immense potential to be used as biopesticides.

“…Ghumare and Mukherjee (2003) had also attributed low levels of ECI in S. litura larvae fed on mint and cotton leaves to higher levels of phenolics in them as compared to other host plants. Gautam et al (2018) had also reported a significant decline in all the nutritional parameters when the second instar larvae of S. litura were fed on polyphenolic rich extracts of Acacia nilotica (Linnaeus). The AD of the larvae was found to increase in the treated larvae as compared to control (Table 3).…”

In an endeavour to explore secondary metabolites as an important and safe means of pest management, we investigated the effects of pyrogallol, a phenolic compound, on the growth and development of Spodoptera litura (Fab.). It is a serious pest of a large number of economically important crops. Different concentrations viz., 1, 5, 25, 125, 625, 3125 ppm of pyrogallol were incorporated in artificial diet of larvae and the antibiosis influence was ascertained by feeding second instar larvae on this diet. The larval and total development period increased significantly with increase in concentration of the pyrogallol. Inhibitory effects of the compound were observed on per cent pupation, per cent emergence and adult longevity. All nutritional indices were also significantly affected. Thus it can be considered as a promising substance to be used as a biopesticide against the insect pest.
