Abstract:
Forty-three species of insects and mites belonging to 21 families and four orders have been found associated with seven species of medicinal plants (Angelica dahurica Benth. et, Atractyloides macrocephala Koidz, Crinum latifolium L., Datura metel L., Phylanthus urinaria L., Geranium nepalense Kudo, Silybum marianum L.) at the Research Center for Medicinal Plants - Hanoi in the winter-spring crop 2003-2004. In addition, 22 species of pathogens including fungi, bacteria and viruses were also recognized. Some unknown pathogens remained to be identified. The density and damage caused by some main insects and pathogens such Wi Spodoptera litura Farb.; Argyrogramma agnata Standinger; Homona coffearia Nietnex, Noctuidae;Erwinia carolovora; Alternaria sp. have been investigated. Initial study on the chemical control method has been conducted. Further investigation is need in 2004-2005 seasons to determine other causal agents and effective control for the studied medicinal plants
