Zusammenfassung: | The activity and chemical composition of volatile oils and crude extracts from hydrodistillations of aerial parts of
Dysphania ambrosioides
(L.) Mosyakin & Clemants, Amaranthaceae, grown in hydroponic systems and soil were investigated. The insecticidal and repellent activities of
D. ambrosioides
against
Sitophilus zeamais
were also explored due to its current use in pest control. The volatile oil of
D. ambrosioides
from plants grown in hydroponics and soil was extracted and characterized by gas chromatography coupled to mass spectrometry. The major volatile compounds from the hydroponic plant material (yield = 0.54%) were
trans
-chrysanthenyl acetate (35.38%) and α-terpinene (49.05%), while those from the plants grown in soil (yield = 1.07%) were isoterpinolene (34.22%) and α-terpinene (43.40%). Both residual waters were used to obtain crude extracts, which were analyzed by ultra-performance liquid chromatography coupled with mass spectrometry and contained rutinoside and some of its derivatives as major constituents. The study revealed repellency of 28% (1 h) and 55.5% (24 h) by volatile oils from hydroponic plants and 30% by the crude extracts after 1 h and for up to 24 h. Regarding the insecticidal activity by the grain mass treated method, both volatile oils presented satisfactory activity up to 120 h, with a response index above 90% after 48 h. The grain mass loss was lower for both oils, reducing
ca
. 50% of mass loss. Therefore,
D. ambrosioides
volatile oils and crude extracts from hydroponics and soil are both candidates for the development of bioinsecticides against
S. zeamais
