Another type of insecticidal activity is antifeedant activity. A new germacranolide isolated from T. argenteum ssp. argenteum was examined for antifeedant activity against neonate larvae Spodoptera littoral is (Noctuidae). Feeding inhibition of 8a-angeloyloxycostunolide was studied by incorporation of three doses into an artificial diet (Table 9). This compound was found to show antifeedant activity, without any toxic effect itself [33]. 

The antimicrobial polymethylated flavones, 5-hydroxy-3,6,7,8,4 -pentamethoxyflavone, 5-hydroxy-3,6,7,8-tetramethoxyflavone and 5,6-dihydroxy-3,7-dimethoxyflavone, have been isolated from Gnaphalium affine D Don. [229,230], These flavonoids showed antimicrobial activity against Spodoptera litura. Structure-activity studies suggested the importance of the 6-position substitution of the flavonoid however, hydrophilic substituents decreased the activity. The flavonoid 8-0-(2-methyl-2-butenoyl)-5,7-dihydroxy-3-methoxyflavone isolated from Gnaphalium robustum L. also inhibited the growth of Escherichia coli [231].

Three cinnamic acid derivatives (305-307) were isolated from the rhizomes of K. galanga [273]. Compound 306 was also found in the extract of AT. pulchra [271]. Ethyl /j-methoxycinnamate (306) was reported to inhibit monoamine oxidase [248] and to have cytotoxic activity [251]. Cinnamic acid derivatives obtained from K. galanga were shown to possess larvicidal activity [273]. Ethyl cinnamate as well as ethyl p-methoxycinnamte from the rhizomes of K. galanga was highly toxic against larvae of Spodoptera littoralis [159]. A monoterpene ketone, 3-...
