Abstract Greening is a citrus plant disease caused by gram-negative bacteria and transmitted by insect vectors. Citrus greening disease has a severe impact in the citrus worldwide production. The economic loss caused by this disease, both in Brazil and the United States of America, is extremely significative with great revenue losses. There are no known curative methods to combat the citrus greening disease. Its control is preventive with an aggressive removal of the infected citrus plants leading to severe economic impacts. Alternative strategies include biological and chemical control programs. Chemical control programs are based on the use of pesticides against the insect vector. However, currently employed chemical programs are not very effective as the citrus psyllids has developed resistance to the commonly used pesticides. This may be an emerging concern for the control of citrus greening disease. Therefore, the development of a new and more effective chemical control program is need and urgent. To accomplish that, it is important to understand the movement of citrus psyllids and why pesticides have little effect at slowing their spread. In this way, the evaluation of the distribution on plants of the commonly used pesticides is essential. There are several traditional analytical techniques employed for pesticides analysis in real samples, however almost none of them allows to perform the analysis in the field. Microfluidic analytical devices are a new trend in analytical determinations. Its advantages include rapid analysis, on-chip detection, low sample amount needed, low cost and the possibility to perform analysis in the field, which provides faster results. The present project aims to develop a new microfluidic analytical device for the analysis of some pesticides in the field. The developed microfluidic device will be employed to analyze samples from Florida (USA) citrus plants fields, which will allow a better understanding of the pesticide distribution in plants and will provide a better handle on managing the citrus greening disease. | |
