Biological activities of the salannin type of limonoids isolated fromAzadirachta indica A. Juss were assessed using the gram pod borerHelicoverpa armigera (Hubner) and the tobacco armywormSpodoptera litura (Fabricius) (Lepidoptera: Noctuidae). Inhibition of larval growth was concomitant with reduced feeding by neonate and third instar larvae. All three compounds exhibited strong antifeedant activity in a choice leaf disc bioassay with 2.0, 2.3 and 2.8 (μ/cm2 of 3-O-acetyl salannol, salannol and… Expand
Bioactivities of Allium longicuspis Regel against anthracnose of mango caused by Colletotrichum gloeosporioides (Penz.)
TLDR
The findings support the potential use of Allium longicuspis extracts as an alternative to synthetic fungicide in mango fruit to inhibit the anthracnose infection. Expand
Biological activities of Moringa oleifera Lam. against anthracnose of mango caused by Colletotrichum gloeosporioides Penz.
TLDR
The efficacy of MOE was relatively superior to synthetic fungicide based on protective, curative and simultaneous treatments and can be applied as curative, protective and simultaneous treatment on mango fruit to inhibit the anthracnose infection. Expand
Effect of PONNEEM# on Spodoptera litura (Fab.) and its compatibility with Trichogramma chilonis Ishii
TLDR
The PONNEEM was found to be compatible with Trichogramma chilonis Ishii, an egg parasitoid of many lepidopteran pests, and showed growth disruption activity against fourth instar larvae. Expand
Effect of crude extracts and purified compounds of Alpinia galanga on nutritional physiology of a polyphagous lepidopteran pest, Spodoptera litura (Fabricius).
TLDR
Ethyl acetate extract was found to be the most effective causing significant reduction in values of RGR, RCR, ECI and ECD of S. litura larvae in comparison to control larvae. Expand
Chemical composition, toxicity and physiological effects of essential oil of Rosemarinus officinalis on lesser mulberry pyralid, Glyphodes pyloalis Walker (Lepidoptera: Pyralidae)
TLDR
The essential oil affected the insect's some key metabolic compounds like; lipid, protein and carbohydrates and was also significant in the activities of certain key enzymes like; alpha- amylase, lipase, protease, glutathione-s-transferase and esterases. Expand
Effects of Neem-Based Insecticides on Consumption and Utilization of Food in Larvae of Spodoptera eridania (Lepidoptera: Noctuidae)
TLDR
Larvae of S. eridania were more sensitive to pure neem oil than to Azatrol, which may reflect interference of neem with regulation of feeding and metabolism, as well as with anatomy and function of midgut tissues. Expand
Effect of Neem-Based Botanicals and Abamectin 1.8% EC Against Phyllocnistis citrella1 in Citrus reticulata (Rutaceae) Nursery Plantations
TLDR
Larvae of P. citrella were more sensitive to A. indica oil than to extract but also better controlled citrus leafminer larvae and might be considered a promising tool for management of citrus Leafminer. Expand
The insecticidal potential of Piper ribesioides (Piperales: Piperaceae) extracts and isolated allelochemicals and their impact on the detoxification enzymes of Spodoptera exigua (Lepidoptera: Noctuidae)
TLDR
Neither induction nor inhibition of detoxification enzymes due to treatment of extracts were statistically significant, however, individual compounds like cinnamic acid, methyl cinnamate, piperine, pinostrobin, pinocembrin, and lemairamin did show a moderate impact on these enzymes. Expand
In vitro response of Phomopsis theae to the products of Azadirachta indica and extracts of Warburgia ugandensis
TLDR
Nimbecidine and bark extracts of W. ugandensis were compared with standard fungicides, Topsin and Saaf, and the extract was comparable to the fungicides both in solid and liquid media. Expand
Efficacy of nucleopolyhedrovirus and azadirachtin on Spodoptera litura Fabricius (Lepidoptera: Noctuidae)
TLDR
Food consumption, efficiency of conversion of ingested and digested food, relative growth rate, and consumption index values declined significantly, but at the same time an increase in approximate digestibility was also observed. Expand

Antifeedant and growth inhibitory effects of the limonoid toosendanin and Melia toosendan extracts on the variegated cutworm, Peridromasaucia (Lep., Noctuidae)
TLDR
Nutritional analyses of 4th instar larvae following both oral and topical administration of toosendanin or the 75% extract confirm that both materials possess a combination of antifeedant and growth inhibitory properties. Expand
6beta-hydroxygedunin from Azadirachta indica. Its potentiation effects with some non-azadirachtin limonoids in neem against lepidopteran larvae.
TLDR
It is obvious from the present study that potentiation among non-azadirachtin limonoids having explicitly two different modes of action, such as feeding deterrence and physiological toxicity, may be playing a significant role in the potentiation effect. Expand
Bioefficacy of toosendanin from Melia dubia (syn. M. azedarach) against gram pod-borer, Helicoverpa armigera (Hübner)
TLDR
Toosendanin seems to specifically induce feeding deterrence in H. armigera larvae and apparently stimulates deterrent receptor cells, which apparently reduces neural input from taste cells specialized to detect feeding stimulants. Expand
Activity of some nonazadirachtin limonoids from Azadirachta indica against lepidopteran larvae
TLDR
The activity among nonazadirachtin limonoids in specific combination as opposed to the structural chemistry having explicitly two different modes of action, like feeding deterrence and chronic toxicity, may be playing a significant role in the multicomponent system. Expand
Antifeedant and toxic activity of Trichilia americana extract against the larvae of Spodoptera litura
TLDR
The biological activity of a crude methanolic extract of Trichilia americana (Sesse and Mocino) Pennington was assessed using the Asian armyworm, Spodoptera litura (Fabr.) to suggest both antifeedant and toxic activities. Expand
Bioefficacy of crude extracts of Aglaia species (Meliaceae) and some active fractions against lepidopteran larvae
TLDR
The isolation of the limonoid complex from A. elaeagnoidea should provide useful starting point for the development of a botanical anti‐insect preparation. Expand
Antifeedant effects of azadirachtin and structurally related compounds on lepidopterous larvae
TLDR
The results showed that hydrogenation of the C‐22,23 double bond did not decrease antifeedant activity and the nature of the substitutes at C‐1, C‐3 and C‐11 were important. Expand
The effect of neem allelochemicals on nutritional physiology of larval Spodoptera litura
TLDR
Results and those from nutritional studies suggest that salannin and nimbinene have no toxicity mediated effects on S. litura larvae and antifeedant activity is a result of the effects on deterrent and other chemoreceptors. Expand
New insect ecdysis inhibitory limonoid deacetylazadirachtinol isolated from azadirachta indica (meliaceae) oil
Abstract Insect bioassay-guided fractionation of neem oil expressed from the fresh fruits of Azadirachta indica (Meliaceae) resulted in the isolation and structural elucidation of a new limonoid,Expand
Effects of azadirachtin on the dietary utilization and development of the variegated cutworm Peridroma saucia
TLDR
Ligature experiments demonstrated that head ligation in last-instar larvae, counteracted the azadirachtin-induced interference with pupation, pointing to an “aza-sensitive head factor”. Expand
