Antifeedant activity of some Tanacetum species and bioassay guided isolation of the secondary metabolites of Tanacetum cadmeum ssp. cadmeum (Compositae)

Feeding Deterrent and Genotoxicity Analysis of a novel Phytopesticide by using Comet Assay against Helicoverpa armigera (HÜbner) (Lepidoptera: Noctuidae)

“…It clearly indicated that the active principles of karanjin and azadirachtin present in the PONNEEM inhibited larval feeding behaviour or made the food unpalatable or the substances directly acted on the chemosensilla of the larva, resulting in feeding deterrence due to synergistic effect. These results corroborated with the findings of Morimoto et al (2002), Susurluk et al (2007), Pavela (2010), andDuraipandiyan et al (2015) who reported that the botanicals possessed similar type of feeding deterrent activity against S. litura. Antifeedant played a major role in the unsuitability of non-host plants as food for the insects.…”

Bidirectional Secretions from Glandular Trichomes of Pyrethrum Enable Immunization of Seedlings

“…For individual compounds, it was demonstrated that they may have specific biological activities, but these activities cannot yet be generalized to an ecological level, and work is needed to study the effects of genetic variation for these traits (Kumar et al, 2005). Susurluk et al (2007) showed that STLs from Tanacetum cadmeum ssp cadmeum aerial plant parts and Tanacetum corymbosum ssp cinereum flowers are effective antifeedants for the generalist larvae of Spodoptera littoralis. Goren et al (1994) studied the flowers of Tanacetum argenteum subsp argenteum (Asteraceae) and isolated a STL that also showed antifeedant activity against the neonate larvae of S. littoralis.…”

<i>Sitophilus granarius</i> L. (Coleoptera) Toxicity and Biological Activities of the Essential Oils of <i>Tanacetum macrophyllum</i> (Waldst. & Kit.) Schultz Bip.

“…cadmeum extracts against Spodoptera littoralis 8 , T. vulgare extracts against Leptinotarsa decemlifineata 9 and T. abrotanifolium extracts against S. granarius and S. oryzae 10 . However the insecticidal activities of Tanacetum essential oils against any insect species were not covered very well in the literature.…”

“…Essential oil composition of many Tanacetum species was covered very well in the literature as well as the essential oil composition of T. macrophyllum. Previously four different studies on the essential oil composition of T. macrophyllum reports the main components as β-eudesmol 89.5 23 , β-eudesmol 21.4 and cischrysanthenol 12 24 ; isobornyl acetate 9.5 , borneol 9.1 , 1,8-cineole 8,6 and γ -eudesmol 6.2 25 and δ -cadienene 11.2-8 , γ -cadinene 8.1-4.5 and unusual compound p-methyl benzyl alcohol 34.1-41.5 26 . According to the previous results the chemical composition of the T. macrophyllum essential oil show variation depending on the geographical origin.…”
