“…Compared to other genotypes, PI 227687 caused the highest mortality and also possesses the highest concentration of the isoflavones genistin and daidzin (Carrão-Panizzi & Kitamura 1995, Piubelli 2000. Bioactivity of isoflavones in insects has been reported by Sutherland et al (1980) and Rao et al (1990) and it is likely that genistin and daidzein have a role in stink bug resistance. Trichomes were also mentioned as cause of nymph death by Panizzi (1991).…”

“…pretense and H. obscurus, ie, secondary metabolites present in the roots can elicit either attractant or repellent behaviour Tapia et al, 2005Tapia et al, , 2007Alarcón et al, 2010;Manosalva et al, 2011). Furthermore, plant-produced isoflavonoids act as phytoalexins and also as insect feeding deterrents (Sutherland et al, 1980) have been shown to play a role in Trifolium -pest interactions eg the isoflavones formononetin, genistein, and biochanin A, present in the leaves of T. subterraneum L. exhibit deterrent activity on the red-legged earth mite Halotydeus destructor (Tucker) (Acari: Penthaleidae) (Wang et al, 1998). Specifically, the accumulation of the isoflavonoid formononetin in the roots of resistant white clover is believed to exhibit a defensive role on the stem nematode Ditylenchus dipsaci (Cook et al, 1995), whilst the presence of formononetin in red clover may act as a deterrent against adult weevils, Sitona lepidus (Gyllenhal) (Coleoptera: Curculionidae) Gerard et al, (2005).…”

In the last decade, there has been increasing interest in investigating the impact of flavonoids on insects, specifically for pest control. In this study, we investigated the impact of isoflavonoids upon the feeding behavior of the clover root borer, Hylastinus obscurus Marsham (Coleoptera: Curculionidae), which is one of the most serious global pests associated with red clover, Trifolium pratense L. Four aglycones isoflavonoids: genistein (1), formononetin (2), daidzein (3) and biochanin A (4) were isolated and identified by HPLC, from roots of two Chilean red clover cultivars. The first two compounds, formononetin (2) and genistein (1), showed high feeding deterrent activity when they were evaluated in artificial diets. This antifeedant effect of isoflavones on feeding behavior of H. obscurus suggests that they are responsible for a decreasedin insect weight gain as compared with the control. This information could be useful respectively, to farmers and researcher to produce and create plants resistant to curculionid.

“…The crude extracts were assayed for feeding deterrent activity as previously described (Sutherland & Hillier 1974;Sutherland et al 1980). The FD5o, the concentration at which feeding was reduced by 50%, was estimated from a dose response curve.…”

Controlled environment conditions were used to compare growth of individual third instar larvae on bean (Phaseolus vulgaris L.) -the roots of which contain phaseollin, a highly active feeding deterrent to larvae of grass grub, Costelytra zealandica (White) -with that on lotus (Lotus pedunculatus Cav.) and white clover (Trifolium repens L.) as resistant and non-resistant controls respectively. After 28 days, 94.6% of larvae were recovered undamaged. Larval weight gain on bean (78 mg) indicated that bean is resistant relative to white clover (108 mg gain) but not as resistant as lotus (62 mg gain). Extracts from roots were examined in toxicity and feeding deterrent bioassays and in chemical analyses. The use of controlled environment conditions provided a sensitive method for measuring resistance of plants.
