Chromolaena odorata (L.) King and Robinson is a native of the tropical Americas and has become a serious invasive weed in the wet/dry tropics of Eastern and Western India. A stem gall fly, Cecidochares connexa (Diptera: Tephritidae) was introduced from Indonesia into India in 2002. A culture of the ...

Chromolaena odorata is a perennial weed which invades forest areas cleared for developing plantations, nurseries, young plantations, and wastelands, but is conspicuously absent in the interior of dense forests or established plantations with closed canopy. The fresh seeds of C. odorata were found...

Two insect species have been established on Chromolaena odorata along the southern coast of KwaZulu-Natal province (KZN), South Africa, and are spreading and increasing in density. Pareuchaetes insulata (Lepidoptera: Arctiidae) has a similar biology to the widely used congener P. pseudoinsulata. A...
