| Název: | Insecticidal and repellent activity of selected essential oils against of the pollen beetle, Meligethes aeneus (Fabricius) adults |
| Abstrakt: | The essential oils from 9 aromatic plants were tested on repellency and mortality of Meligethes aeneus
adults. All the tested essential oils caused high mortality of M. aeneus adults in the tarsal tests. The
lethal doses after 6 h exposure were ranged between 197 and 1508 ug cm-2. Essential oils obtained from
Carum carvi and Thymus vulgaris were most efficient where LD50 was estimated as 197 and 250 g cm-2,
respectively.
Repellency declined in all the essential oils as a function of time. The longest persistence time was
determined for essences obtained from C. carvi and T. vulgaris where significantly the highest repellent
index of 65.6% and 63.8%, respectively, was determined. Repellent index lower than 15% was determined
for the remaining essential oils. |
