Salt marsh plants were tested for their insecticidal activities against larvae of the confused flour beetle Tribolium confusum (Tenebrionidae). 16 aerial part extracts were obtained using organic solvents of increasing polarity and tested for their anti-feedant and toxicity effects. Responses varied with plant material and extract type. Ethyl acetate(More)
Entomopathogenic fungi (EPF) are commonly found in diverse habitats and are known to cause mycoses in many different taxa of arthropods. Various unexpected roles have been recently reported for fungal entomopathogens, including their presence as fungal endophytes, plant disease antagonists, rhizosphere colonizers and plant growth promoting fungi. In(More)
Experiments were conducted to assess the effect of gibberellic acid (GA3), a plant growth regulator, on Locusta migratoria migratoria fifth instar larvae. Newly emerged larvae were exposed to various concentrations of GA3 administered by topical application or by forced ingestion. Results showed that treated insects exhibited toxic symptoms with a(More)
To calibrate biological control in pepper plant against Aphis gossypii using Coccinella algerica different experimentation were made. The consumption of C. algerica during the larval stage was enumerated in laboratory conditions. The densities (1, 4, 8 larvae/plant) to L2 stage of C. algerica necessarily to decrease aphid's populations were determined in(More)
The repulsive activity of Cestrum parquii on the feeding behaviour of Pieris brassicae L. and Spodoptera littoralis Boisduval was studied. Antifeedant effect was observed at regular intervals during a week. Meal uptake was stopped after the first day, showing a strongly antifeedant effect of C. parquii extract on these two species. The impact of C. parquii(More)
The aim of this study was to assess the percentage and constituents variations in flowers and leaves essential oil of three Glebionis coronaria (L.) Tzvelev population, growing wildly in three different ecotypes (Utique, M'saken, and Sahara Lektar) in Tunisia. The chemical compositions of these essential oils were analyzed by the GC and GC/MS systems.(More)
