Resumo
The culture of tomato (Solanum lycopersicum) is subject to a high incidence of pests, and these can occur from sowing to fruit harvest. This study was conducted in order to monitor the field population dynamics of arthropod pests and their predators and obtain subsidies that define alternatives for the management of areas cultivated with creeping tomato produced for industry. Initially, two studies in the areas of cash crops were performed at different times Abadia de Goiás and Palminópolis, two districts of the state of Goiás, which consisted of weekly surveys to quantify population densities of arthropods present in the culture. There was a constant incidence of whiteflies throughout the crop cycle, the low population of beneficial arthropods and from the analysis of applications made with the population indices obtained, it could be observed use of unnecessary applications of pesticides for pest insect species control. Later, there was a test installed in an experimental area with tomato cultivation in Goiânia-GO another district, and aimed to test an alternative form of arthropod pests control, whose treatment consisted of evaluating two different forms of management, standard management, performed in conventional way with the use of pre-established applications, and integrated pest management (IPM). In the standard treatment were performed eleven applications of pesticides to control insect pests, and IPM were performed in four applications, as these were based on population levels of pests in the area of cultivation. In the IPM treatment was observed that the cost of production was 18% lower compared to standard treatment, without significant losses in productivity of tomatoes. The use of integrated pest management proved to be an important tool for controlling tomato pests, to be technically efficient and economically viable.
