The drying kinetics of Urtica dioica leaves in a convective solar dryer was studied. The kinetics of drying is studied for three temperatures (40, 50 and 60 °C), ambient air temperature ranged from 30 to 35 °C. The experimental results are used to determine the characteristic drying curve. Nine mathematical models have been used for the description of the drying curve. The Midilli-Kuck model was found to be the most suitable for describing the drying curves of Urtica dioica leaves. The drying parameters in this model were quantified as a function of the drying air temperature. Moisture transfer from Urtica dioica leaves was described by applying the Fick's diffusion model. Effective moisture diffusivity of the product was in the range of 9.38 – 72.92×10-11 m2/s. A value of 88,49 kJ/mol was determined as activation energy.

Natural pesticides are promising in pest control, especially those derived from plants. In this study, the larvicidal activity and their effect on the reproduction potency of the essential oils of Ruta chalepensis and Eucalyptus camaldulensis were evaluated against the mosquito species Culex pipiens. Newly exuviated larvae of third and fourth instar larvae were exposed to various concentrations of Ruta chalepensis (150-700 ppm) and Eucalyptus camaldulensis (100-600 ppm). The results, for both plants, showed a toxic effect of the treated larval series with dose-response relationship. For Ruta chalepensis oil bioassay the lethal concentrations (LC50 and LC90) were estimated at 95ppm and 550 ppm for the third-instar larvae, respectively, while these respective values were 245ppm and 830ppm for the fourth-instar larvae of Culex ...

Larvicidal assays were conducted according to standard World Health Organization (WHO) .The results have been exploited according to classic statistical methods. A linear correlation was revealed between concentration and larval mortality. At first stage, larval mortality increased from 45.
