Ruta Angustifolia Essential Oil: Behavioral and Insecticidal Effects Against Larvae and Adults of Tribolium castaneum.

The study aims to evaluate the behavioral and insecticidal effects of Ruta angustifolia EO (RAEO) against larvae and adults of a major pest insect, Tribolium castaneum. RAEO exhibited a strong repellency against both adults and larvae where percentages as high as 74 and 72 % of PR (Percentage of Repellency) were recorded respectively, at 0.47 μL/cm after 2 h.

Chemical profiling and bioactivities of essential oils from against .

The use of essential oils has emerged as an ecofriendly solution for controlling different pests, particularly insects of stored products. Essential oils (EOs) from (TC) and (OC) have received less attention for these bioactivities. Therefore, our study aimed to assess the repellent, antifeedant and contact toxicity of their EOs against a major stored product pest .

Effect of 20-Hydroxyecdysone, a Phytoecdysteroid, on Development, Digestive, and Detoxification Enzyme Activities of Tribolium castaneum (Coleoptera: Tenebrionidae).

Plants present a delimited reservoir of biologically active compounds. Many plants synthesize several compounds of secondary metabolism, such as alkaloids, terpenoids, phenolics, steroids, etc. Such compounds are generally thought to be involved in plant-insect interactions.
