Hornaltica bicolorata
leaf-feeding beetle
Hornaltica bicolorata is a leaf-feeding beetle in the family Chrysomelidae. The species has been deployed as a biological control agent against the invasive weed Parthenium hysterophorus in East Africa, particularly Ethiopia and Uganda, where it has demonstrated consistent establishment. It was previously known under the synonym Zygogramma bicolorata in biocontrol literature. The beetle contributes to integrated pest management programs by defoliating the target weed.
