TITLE:

Hybrid polymers in the development of controlled release systems for semiochemicals used in integrated pest management.

KEY WORDS:

Hybrid polymers, adsorbent, semiochemicals.

PAGES: 102
BIG AREA: Ciências Exatas e da Terra
AREA: Química
SUMMARY:

Agribusiness represents a large part of Brazil's gross domestic product. However, to achieve good performance, many techniques need to be adopted, mainly related to the control of pathogens in crops. In fruit production, it is important to overcome the enormous challenge of controlling pests such as the fruit fly. In the case of the cotton crop, the control of the cotton boll weevil is essential for profitability, being considered one of the pests with the greatest potential for damage to the cotton crop. With recent incentives for the expansion of these crops in the Northeast, combined with good market prospects, it becomes necessary to obtain new materials that help in the development of strategies that can be used in integrated pest management programs (IPM). These procedures have significantly improved the appeasement and control effects of pests in the field. Agribusiness represents a large part of Brazil's gross domestic product.

These procedures have significantly improved the appeasement and control effects of pests in the field. In this sense, this work developed new adsorbent materials based on silica precursors and biopolymers, synthesizing hybrid materials capable of mind-controlled release of semiochemicals. These materials were characterized by various techniques, such as Fourier Transform Infrared (FTIR), thermogravimetric analysis (TG), Scanning Electron Microscopy (SEM), X-Ray Diffractometer (DRX), Energy Dispersive Ray Spectroscopy X(EDX) and tested against the release of the compound ethyl octanoate present in the fruit fly pheromonal mixture. For attraction and subsequent elimination of these pests, contributing to their population control in the field.
