Striga hermonthica Striga hermonthica Striga hermonthica, commonly known as purple witchweed or giant witchweed, is a hemiparasitic plant that belongs to the family Orobanchaceae. It is devastating to major crops such as sorghum ("Sorghum bicolor") and rice ("Oryza sativa"). In sub-Saharan Africa, apart from sorghum and rice, it also infests maize ("Zea mays"), pearl millet ("Pennisetum glaucum"), and sugar cane ("Saccharum officinarum"). "Striga hermonthica" has undergone horizontal gene transfer from "Sorghum" to its nuclear genome. The "S. hermonthica" gene, "ShContig9483", is most like a "Sorghum bicolor" gene, and additionally shows significant but lesser similarity to a gene from "Oryza sativa". It shows
Scirpophaga gilviberbis on "Oryza" species, including "Oryza sativa". Scirpophaga gilviberbis Scirpophaga gilviberbis is a moth in the Crambidae family. It was described by Zeller in 1863. It is found on the Comoros and in the Democratic Republic of Congo, Kenya, South Africa, Zambia, India, Indonesia (Java, Sulawesi), Myanmar, Singapore, Thailand and Vietnam. The wingspan is 20–22 mm for males and 23–35 mm for females. The forewings of the males are ochreous with some fuscous scales. The hindwings are white, except for the costal area and the apex which are ochreous. Females have white fore- and hindwings. The anal tuft is whitish grey
