4. In vitro evaluation of the effect of botanical formulations used in the control of Aedes aegypti L. (Diptera: Culicidae) on liver enzymes.
Abstract: INTRODUCTION: Dengue fever is a viral disease transmitted by the Aedes aegypti Linn. (1792) (Diptera: Culicidae) mosquito, which is endemic in several regions of Brazil. Alternative methods for the control of the vector include botanical insecticides, which offer advantages such as lower environmental contamination levels and less likelihood of re

12. NutriÃÃ Mineral em Plantas de Copo de Leite: DeficiÃncia de Nutrientes e AdubaÃÃo Silicatada / Mineral nutrition of calla lily plants: nutrients deficiencies and silicon fertilization
The aspects related to mineral nutrition in ornamental plants are very important to the production of quality flowers. In the specific case of the calla lily (Zantedeschia aethiopica) the information on nutrition and manuring in commercial cultivations are quite incipient. Thus, the objectives of this work were to evaluate the deficiencies of nutrients and d
