Abstract: In this study, we monitored for the impact of three aqueous extracts of plants (Azadirachta indica, Hyptis suaveolens and Solanum lycopersicum) on insect pests abundance in okra (Albermochus esculentus L.) crop, compared to a synthetic chemical « SAUVEUR 62 EC », having as active ingredients, acetamiprid 32g/l and Lambda-cyhalothrin 30g/l. Foliar applications by these extracts were done using manual sprayers. After treatment, the insects were... More

Abstract: Ground dwelling insects, spiders, and other arthropods play an important role in agroecosystems as predators and saprophytic organisms. Their presence on the soil surface helps the biological control of pests, enhances organic matter decomposition and promotes biodiversity. Soil disturbance, particularly tilling and mowing has greatly affected the assemblage and abundance of epigeic arthropods. This study aimed to determine the effects of... More

Abstract: Plantation under the forest is a good way of agroforestry, but the canopy closure has a great influence on understory herbs’ growth. In the study, different canopy closures of Phyllostachys pubescens forests were set up to explore its influence on the growth of Ilex latifolia Thunb. The photosynthetic characteristics of Ilex latifolia leaves under different canopy closures were determined by Li-6400 portable photosynthetic system. The results... More

Abstract: Urban climate is considered one of the most important environmental criteria in urban planning, since it significantly affects the project and its placement in the space. Climate conditions are central to the study, with winds in the urban environment, their direction, intensity and changes taken into consideration designing the new interventions in space. The results of the case study were applied to the project with the intention of supporting... More
