(Moraceae), has been used for insect control for many years; the ripe fruit of this tree was historically placed in cupboards or basements to repel cockroaches. t> Results of past research indicate that there may be some scientific validity to this well-popularized use. 2-s) Dichloromethane extracts repelled the maize weevil Sitophilus zeamais Motschulsky; but repellency decreased as extracts increased in purity (Peterson, unpublished). Repellency to highly purified (:?: 98%) osajin and pomiferin, two major isofiavonoid components of the osage orange9•10> (Figure I) was not significant. 11>
