3 7 tri methyl xanthine a new chemo sterilant for stored grain pest callosobruchus chinensis



3 7 tri methyl xanthine a new chemo sterilant for stored grain pest callosobruchus chinensis



Zeitschrift Fuer Angewandte Entomologie: 378-381



A compound 1,3,7-trimethylxanthine, was isolated from seed extract of Coffea arabica. It proved effective as a chemosterilant for Callosobruchus chinensis, causing nearly 100% sterility at a concentration of 1.5%. At a similar concentration the compound had no phytotoxic effect on the crop plant Vigna mungo. Use of the compound for control of stored-grain pests is suggested.
