The phagodepression activity of five furanocoumarins (FC), bergapten, xanthotoxin, psoralen, imperatorin, and angelicin, has been studied against larvae of Egyptian cotton leafworm Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) using a leaf-disk choice bioassay. The dose range used was 0–10 μg/cm2 for linear furocoumarins and 0–30 μg/cm2 for angelicin, the angular furanocoumarin. Dose–feeding deterrency activity correlations were governed by various sigmoidal functions, except in… Expand
Acaricidal activity and sublethal effects of an oxymatrine-based biopesticide on two-spotted spider mite (Acari: Tetranychidae)
TLDR
Viability and reproduction of survivors, as well as population growth, were strongly affected after the treatments of preovipositional females and female teleiochrysales with 100, 50 and 25 μl/l, which were discussed as a starting point for further research aimed to improve management of T. urticae populations.

Antifeedant activities of secondary metabolites from Ajuga nipponensis against Plutella xylostella
TLDR
Antifeedant activities of seven chemicals isolated from Ajuga nipponensis were examined in a bioassay against 3 rd instar larvae of Plutella xylostella and only apigenin showed effectiveness against Diamondback moth. Expand
ANTIFEEDANT ACTIVITIES OF METABOLITES FROM AJUGA 1985 Plant extracts and insecticide : Secondary compounds
Antifeedant activities of seven chemicals isolated from Ajuga nipponensis were examined in a bioassay against 3 instar larvae of Plutella xylostella. Five compounds (luteolin, stigmasterol, acacetin,Expand
Accumulation of furanocoumarins by Bituminaria bituminosa in relation to plant development and environmental stress.
TLDR
There was a significant, positive correlation between the FC and nitrogen concentrations in the plant organs analysed (both increased in the order: fruits > growing leaves > mature leaves), reflecting their respective contributions to plant fitness. Expand
Individual and synergistic toxicity of solanaceous glycoalkaloids against two coleopteran stored-product insects
TLDR
The study recommends the use of glycoalkaloids of Solanaceae as biorationals and natural leads to protect stored grains from insect infestation. Expand
Toxicity and Synergism in the Feeding Deterrence of Some Coumarins on Spodoptera frugiperda Smith (Lepidoptera: Noctuidae)
TLDR
Binary equimolar mixtures of the natural coumarins were phagodepressors against S. frugiperda larvae surpassing the expected additive responses, indicating that these compounds can act synergistically against the larvae of thisepidoptera. Expand
Bioprospecting insecticidal compounds from plants native to Mato Grosso do Sul, Brazil
TLDR
An evaluation of the insecticidal activity of extracts prepared from leaves of Tapirira guianensis Aubl. Expand
Larvicidal activity of Cnidium monnieri fruit coumarins and structurally related compounds against insecticide-susceptible and insecticide-resistant Culex pipiens pallens and Aedes aegypti.
TLDR
The structure-activity relationship indicates that the chemical structure and alkoxy substitution and length of the alkoxyl side chain at the C8 position are essential for imparting toxicity. Expand
Nematicidal coumarins from Heracleum candicans Wall.
TLDR
The root extract of Heracleum candicans Wall exhibited antagonistic activities against nematodes Bursaphelenchus xylophilus and Panagrellus redivivus and was the first report about species in the Umbelliferae family that possesses nematicidal activity. Expand
Development and Survival of Spodoptera exigua (Lepidoptera: Noctuidae) on Alternate Crops in Cotton Cropping Pattern, with Implications to Integrated Pest Management
TLDR
It is concluded that S. exigua when fed on spinach was greatly disadvantaged in terms of growth and development; hence, the pest's field population can be opportunistically controlled by spraying adjacent spinach fields. Expand

Enzymatic Adaption in a Specialist Herbivore for Feeding on Furanocoumarin‐ Containing Plants
TLDR
The ability to tolerate this compound further suggests that D. pastinacella is a specialist on furanocoumarin-containing hosts, and the importance of these enzymes in the detoxification of xanthotoxin was further suggested. Expand
Feeding Deterrence of Spodoptera exigua (Lepidoptera: Noctuidae) Larvae by Low Concentrations of Linear Furanocoumarins
TLDR
It is concluded that linear furanocoumarins (at the concentrations found in A. graveolens ) can play an important role as behavioral modifiers rather than as toxic defenses against larvae of the generalist herbivore S. exigua. Expand
Development of Insecticide–Resistant and –Susceptible Spodoptera exigua (Lepidoptera: Noctuidae) Exposed to Furanocoumarins Found in Celery
TLDR
Results suggest that differential selection for furanocoumarin tolerance among these populations may occur because of the diversity of S. exigua exposure to insecticides and host plants varying in linear furamocou marin content. Expand
Interaction Between Linear Furanocoumarins Found in Celery and a Commercial Bacillus thuringiensis Formulation on Spodoptera exigua (Lepidoptera: Noctuidae) Larval Feeding Behavior
TLDR
The results indicate the importance of considering the behavioral ecology of insect herbivores in estimating the compatibility of secondary plant compounds and entomopathogens for the development of integrated pest management programs. Expand
Fungistatic Activity of Ruta graveolens Extract and Its Allelochemicals
TLDR
A rue lyophilized extract was shown to reduce radial growth of all six fungal species significantly at concentrations ranging from 5.0 to 40.0 g/liter, suggesting potential role for the rue extract and its allelochemicals in controlling pathogenic fungal infections. Expand
Patterns of Furanocoumarin Distribution and Insect Herbivory in the Umbelliferae: Plant Chemistry and Community Structure
TLDR
Chemical survey of 12 species of Umbelliferae revealed that species possessing furanocoumarins are most frequently found in open habitats: either swamps or thickets or disturbed areas such as roadsides or old fields, and Cluster analysis of the insects on these umbellifers demonstrates that insect herbivores distribute themselves according to host furanOCoumarin chemistry.

Toxicity of linear furanocoumarins toSpodoptera exigua: Evidence for antagonistic interactions
TLDR
The linear furanocoumarins psoralen, bergapten, and xanthotoxin were tested for toxicity to the beet armyworm Spodoptera exigua under short ultraviolet (UVB) radiation and the enigma the findings represent for plant-insect relationships are discussed. Expand
Furanocoumarin Induction in Wild Parsnip: Evidence for an Induced Defense against Herbivores
TLDR
It is found that furanocoumarin induction can account for much of the reduced larval growth associated with induction in intact plants, which is likely to represent an adaptation to herbivory. Expand
Possible ecological significance of within-fruit and seed furocoumarin distribution in twoPsoralea species
TLDR
The cooccurrence of linear and angular isomers seems to be a chemical marker of the genusPsoralea: the biosynthetic pathway leading to the angular isomer as an evolutionary response to selective pressure from herbivore insects is suggested. Expand
