TLDR
Astilbin was isolated in high yield from Dimorphandra mollis, and its insecticidal and growth inhibiting activity by stomach ingestion were evaluated against Anticarsia gemmatalis and Spodoptera frugiperda as discussed by the authors.Abstract:
Astilbin was isolated in high yield from Dimorphandra mollis, and its insecticidal and growth inhibiting activity by stomach ingestion were evaluated against Anticarsia gemmatalis and Spodoptera frugiperda. The insecticidal activity of astilbin, the weight reduction of the larval phase and the prolongation of the larval and pupal phases were verified for both species. Astilbin was identified on the base of its NMR, MS and physical data.read more

Insecticidal activity of chemical constituents from Aristolochia pubescens against Anticarsia gemmatalis larvae.
TL;DR: Acetone and ethanol extracts of the tubercula and several compounds isolated from Aristolochia pubescens were bioassayed on velvetbean caterpillars, Anticarsia gemmatalis, for evaluation of the insecticidal activities.

Antifeedant and toxic activity of some plant extracts against larvae of cotton leafworm Spodoptera littoralis (Lepidoptera: Noctuidae).
TL;DR: The biological activity of crude petroleum ether extracts of Oshar (Calotropis procera), Harmal (Rhazya stricta) and Hargal (Solenostemma argel) were assessed using the 4th larval instar of cotton leafworm Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae).

Astilbin inhibits the adhesion of T lymphocytes via decreasing TNF-α and its associated MMP-9 activity and CD44 expression
TL;DR: The findings suggest that the inhibition of T lymphocyte adhesion by astilbin may be related to the reduction of the CD44 expression and TNF-alpha production in the cells, which may further cause a decreased MMP-9 secretion.

Phenolics in ecological interactions: The importance of oxidation.
TL;DR: It is argued that physicochemical conditions of the environment that control phenolic oxidation generate variation in ecological activity and that experiments must be designed with conditions appropriate to the biochemical mode of phenolic action.

Herbivores and Plant Tannins
TL;DR: The chapter concludes with an overview and summary of potential roles of tannins in plants other than defensive activity against herbivores, and suggestions for research needs.

Flavonoids from Hypericum perforatum show antidepressant activity in the forced swimming test.
TL;DR: The validity of a flavonoid fraction obtained from a crude extract of Hypericum perforatum was checked in open field experiments and in the FST after 12 days of daily treatment to exclude false positive results.

Toxicity of tomato phenolic compounds to the fruitworm, heliothis zea
Murrey B. Isman,Sean S. Duffey +1 more
TL;DR: In this paper, the authors found that chlorogenic acid and rutin, major phenolic constituents of tomato foliage, as well as a phenolic-rich aqueous extract of tomato leaves, inhibit early larval growth of Heliothis zea, when added to an artificial diet for this insect.

Growth inhibitory effects on fall armyworm Spodoptera frugiperda of some limonoids isolated from Cedrela spp. (Meliaceae).
TL;DR: All the tested compounds except cedrelanolide showed comparable activity to that of toosendanin, and all the compounds tested inhibited larval growth, compared to the control, in a concentration-dependent manner.
