INSECTICIDAL ACTIVITY OF Inula viscosa L. (Asteraceae) ESSENTIAL OILS ON ADULTS OF Bactrocera

Since the discovery of numerous negative impacts associated with the widespread use of chemical insecticides, ecologists have been on the lookout for effective biological pest control strategies. Plant-based extracts, such as essential oils, are becoming more popular as alternatives to toxic compounds.

The purpose of this research is to see how sensitive Bactrocera oleae Gmel (Diptera - Tephritidae) adults are to essential oils from Inula viscosa L. (=Dittrichia viscosa) (Asteraceae) from the Sidi Bel Abbes region (North West Algeria).

The essential oils were extracted from the aerial portions using hydrodistillation. Toxicity studies were carried out in Petri boxes in a laboratory setting. Adult Bactrocera oleae were treated to various concentrations of our plant's essential oils. The volatile essences of I. viscosa offer remarkable insecticidal effects, according to tests. They cause 100 percent adult mortality after 96 hours of exposure at a concentration of 8 l / ml. They show toxicity through touch after the first day of exposure to the four concentrations evaluated. There was no mortality in the control boxes that were only treated with acetone.

Essential oils from Inula viscosa L. have been shown to be effective against the olive fly, therefore this oil could be utilised to battle some bug species.
