Insecticidal Compound in Tuber of <i>Cyperus rotundus</i> L. against the Diamondback Moth Larvae

Natural products inCyperus rotundusL. (Cyperaceae): an update of the chemistry and pharmacological activities

“…121 Compound 17 obtained from the tubers of this plant species also showed insecticidal activity. 122 Isocyperol (18) has been found to signicantly inhibit LPSinduced production of nitrite oxide (NO),PGE2 and suppressed LPS-induced expression of inducible nitric oxide synthase (iNOS) and COX-2 at the mRNA and protein levels in RAW 264.7 macrophages. 123 Extraction of air-dried and chopped rhizomes of CR with hot 70% EtOH followed by purication using GC-MS afforded monoterpenes, sesquiterpenes and aromatic compounds (10,17,(37)(38)(39)(40)(41)(42)(43).…”

Efficacy of plant extracts for reducing larval populations of the diamondback moth, Plutella xylostella L.(Lepidoptera: Yponomeutidae) and cabbage webworm, Crocidolomia binotalis Zeller(Lepidoptera: Pyralidae), and evaluation of cabbage damage.

“…The extracts of A. galanga, A. cardamomum, C. rotundus and G. globosa resulted in high mortality against P. xylostella larvae by our feeding method in the laboratory assay (Dadang et al, 1996). In addition, active compounds from C. rotundus and A. galanga have been isolated and elucidated as acyperone and 1Ј-acetoxychavicol acetate (Dadang et al, 1996(Dadang et al, , 1998.…”

“…In addition, active compounds from C. rotundus and A. galanga have been isolated and elucidated as acyperone and 1Ј-acetoxychavicol acetate (Dadang et al, 1996(Dadang et al, , 1998. These results prompted us to conduct the present research in order to test their efficacy on cabbage cultivation under field conditions.…”

Priprioca (Cyperus articulatus var. nodosus, Cyperaceae) Hydrolate as Larvicidal against Aedes aegypti

“…The results showed that C. giganteus has highest biocidal effect compared to C. rotundus. One of the major compounds of essential oil from C. rotundus is α-cyperone (Kilani et al 2005, Tam et al 2007 and it present insecticidal potential against clothes moth and beetles (Dadang et al 1996, Adedire et al 1999. Nevertheless, the presence of α-cyperone has not been reported in tested essential oil of C. rotundus.…”
