In the search for a means of controlling the toxic weed Halogeton glomeratus Mey. that infests millions of acres in the Western United States, the phycitid moth Heterographis fulvobasella Ragonot was studied. This moth attacks and damages the closely related species, Halogeton sativus Mey., in Morocco and Spain. Biology, distribution, and host-specificity tests of the moth are described.

Oviposition and larval starvation tests indicated that the moth could complete its life cycle only on Halogeton sativus, Kochia scoparia Schrad., and Salsola kali L. under laboratory conditions. Twenty-five other plant species and varieties of the families Chenopodiaceae, Graminae, Solanaceae, Cruciferae, Umbelliferae, Polygonaceae, and Leguminoseae were tested. All of these proved to be unsuitable hosts. Tests with Halogeton glomeratus were not conclusive.
