A test on a variety of barley “Fouara” was carried out to verify the effects of treated wastewater on some physio-morphological parameters of this plant. Two different types of irrigation were chosen, one using treated wastewater from the Ain Beida wastewater treatment plant, and the other, ordinary water serving as a control. The physicochemical results of the treated wastewater showed, in particular, the EC, NH4, NO3 and the DCO/DB05 ratio do not exceed the admissible standards when they reach their maximum values The physio-morphological parameters of barley respond positively to the use of this water; represented by the two averages of the 'sugar' parameter which shows a clear difference depending on the water category (T and S) or the control individuals express an average (0.055) significantly lower than that of the S individuals (0.847). We note that significant values of the positive correlation coefficient of r=0.812 between the two parameters TRE and SF, therefore there is an association between these two factors. But negative for the TRE and PSF (r = -0.722). This means that the values of the two parameters do not evolve in the same direction. The factors 'sugar' and 'chlorophyll b' present the best correlation, they better represent the six individuals and the proline contents are higher in the treated plants.

Essential oils play a crucial role in biological control against parasites threatening the beekeeping stock, both in Algeria and globally. Their appropriate use helps reduce the adverse effects of chemical products on human health and the environment. The purpose of this study is to analyze the components of Eucalyptus pauciflora essential oil grown in Algeria and to evaluate its impact on the marine shrimp Artemia salina and the mite Varroa destructor, while also comparing it to other species of Eucalyptus from the same region namely, Eucalyptus robusta, globulus, sideroxylon, and amygdalina, which have been examine in previous research. Steam distillation of fresh leaves from Eucalyptus pauciflora yielded 0.73% essential oils. This plant contains a total of thirty-nine chemical compounds, among which the most significant are 1,8-cineole (57.45%), β-cymene (5.44%), spathulenol (5.38%), trans-verbenol (4.31%), and α-pinene (3.11%). A lethality test on brine shrimp (BSL) revealed that Eucalyptus pauciflora exhibits toxicity with a median lethal concentration (LC50) of 53.51 ppm. Field trials conducted on hives infested with Varroa destructor showed that the acaricidal effect of Eucalyptus pauciflora is superior to that of amygdalina and sideroxylon species, but inferior to that of globulus and robusta species, all sourced from the same herbarium (Draa Naga) in northeastern Algeria. The results of this research highlight the benefits of Eucalyptus essential oils to be integrated into the formulation of natural acaricides that are environmentally friendly to combat Varroa destructor infestation.
