4. Synthesis of new α-amino nitriles with insecticidal action on Aedes aegypti (Diptera: Culicidae)
Abstract Aedes aegypti is the principal vector of arboviral pathogens that may cause diseases as dengue fever, chikungunya and zika. The harmful environmental effects of commercial pesticides coalesced with the development of insecticide-resistant populations encourage the discovery and generation of new alternative products as a tool to reduce the incidence

5. Economic Viability of Tomato Cultivation in Organic Farming System
ABSTRACT The aim of the present study is to evaluate the economic viability of tomato cultivation in a system of organic farming, and to compare it with the conventional farming system. The fixed and variable costs of both cultivation systems were calculated, as well as the costs of disease control with the application of alternative products and pesticides.

6. VALIDAÇÃO DE MÉTODO POR MEFS-HS/CG-EM PARA DETERMINAÇÃO DE CARBARIL EM PLASMA SANGUÍNEO
The aim this research is to develop a HS-SPME/GC-MS method to analyze the carbaryl in blood plasma samples of the rural workers, who live round the perimeter of Chapada do Apodi-CE. This was achieved by chromatographic signal of the 1-naftol, degradation product of carbaryl with the intention of evaluating the degree of exposure of the workers to pesticides,

7. CONSTRUCTION AND PRACTICAL APPLICATION OF A CANOPY OPENER DEVICE
ABSTRACT: Accurate application of pesticides is difficult for crops with dense leaves, such as soybean crops. To improve spray deposits on the lower leaves of soybean plants, the aim of this study is to build a canopy opener (CO) from a previously developed prototype and to assess its practical application and efficiency on soybean crops. Laboratory experime

8. MICROEXTRAÇÃO LÍQUIDO-LÍQUIDO DISPERSIVA ASSISTIDA POR VORTEX E ULTRASSOM APLICADA À DETERMINAÇÃO DE AGROTÓXICOS TRIAZINAS, TRIAZINONAS E O TRIAZOL FLUTRIAFOL EM ÁGUA
This study aimed at developing and validating a method for the simultaneous determination of triazines (ametryne, atrazine, prometryne and terbuthylazine), triazinones (metribuzin and hexazinone) and a triazole (flutriafol) in water by ultrasound vortex assisted dispersive liquid-liquid microextraction (USVADLLME) and GC-MS. The experimental conditions that

9. Ozone Treatment for the Removal of Residual Chlorothalonil and Effects on the Quality of Table Grapes
Due to uncontrolled use of pesticides and disregard for harvest intervals, some pesticide residue is present in various foods. Treatments using ozone as an alternative for food decontamination have been studied in recent years due to ozone’s high oxidation potential even at low concentrations. The present work aimed to evaluate chlorothalonil removal from

11. Diversidade genética de Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) e caracterização molecular das linhagens de Wolbachia associadas / Genetic diversity of Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) and molecular characterization of the associate strains of Wolbachia
Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) is an exotic insect in Brazil, first recorded in the 40s. Although it causes direct damage, D. citri only received attention as a pest in 2004, when the \"Huanglonbing\" (HLB) disease was confirmed infecting citrus in Brazil, and subsequently related to D. citri as vector. Currently, there is no cure for

12. Aleopatia de fungos fitopatogÃnicos sobre plantas invasoras das culturas de soja e milho / Allelopathy of plant pathogenic fungi on invasive plants on the cultures of soybean and corn
Invasive plants can cause problems to the exploitation of agriculture worldwide. The chemical control of these plants has generated several environmental problems, such as the contamination of natural resources, the compromising the food quality, the poisoning of farmers, the development of the weedâs resistance, among others. An alternative to reduce the u
