Insecticidal actions of Curcuma longa L. to Plutella xylostella and Nilaparvata lugens Stal

Morallo-Rejesus B., . and Maini H., . and Sayaboc A.S., . and Hernandez H., . and Quintana E., . (1990) Insecticidal actions of Curcuma longa L. to Plutella xylostella and Nilaparvata lugens Stal. [Proceedings Paper]

Curcuma longa L. Zingiberaceae is a common medicinal plant in the Philippines known as yellow ginger and is also used as condiment and food dye. This species is a new addition to the five species of Curcuma amada angustifolia aromatica domestica and zedoaria reported in 1988 exhibiting insecticidal properties. Several extracts water petroleum ether chloroform CE and ethanol were evaluated for contact and ovicidal toxicities and as feeding detergent of diamondback moth DBM Plutella xylostella L. and brown planthopper BPH Nilaparvatalugens Stal. Petroleum ether PE was the most toxic topically causing 94 percent mortality at 200 ug/insect to DBM. This extract was also toxic to BPH. The water extract also caused 87 to 90 percent mortalities to DBM by filter impregnation method. Both PE and CE inhibited the feeding behavior of DBM. Five fractions A B C D and E were isolated from the petroleum ether extract and only B exhibited contact toxicity to BPH. But all fractions were ovicidal to DBM. Purification and identification of the above active fractions are being pursued. Curcuma longa L. exhibits contact and ovicidal toxicities and antifeedant property.

Abstract

Curcuma longa L. Zingiberaceae is a common medicinal plant in the Philippines known as yellow ginger and is also used as condiment and food dye. This species is a new addition to the five species of Curcuma amada angustifolia aromatica domestica and zedoaria reported in 1988 exhibiting insecticidal properties. Several extracts water petroleum ether chloroform CE and ethanol were evaluated for contact and ovicidal toxicities and as feeding detergent of diamondback moth DBM Plutella xylostella L. and brown planthopper BPH Nilaparvatalugens Stal. Petroleum ether PE was the most toxic topically causing 94 percent mortality at 200 ug/insect to DBM. This extract was also toxic to BPH. The water extract also caused 87 to 90 percent mortalities to DBM by filter impregnation method. Both PE and CE inhibited the feeding behavior of DBM. Five fractions A B C D and E were isolated from the petroleum ether extract and only B exhibited contact toxicity to BPH. But all fractions were ovicidal to DBM. Purification and identification of the above active fractions are being pursued. Curcuma longa L. exhibits contact and ovicidal toxicities and antifeedant property.
