SUMMARY:

With the recent incentives to expand cotton cultivation in the northeast, together with the good current market prospects, it is necessary to obtain new materials that help in the development of alternative strategies that can be used in integrated pest management programs (MIP) ), mainly in the control of the cotton weevil (Anthonomus grandis), considered one of the pests with the greatest potential for damage to the cotton crop. One of the factors that influence the efficiency of semiochemicals in the field is the rate of release of these compounds, which need to mimic the release of insects in nature. Several adsorbent materials have been presented in the literature as a device for releasing semiochemicals, such as rubber septa, substrates of silica nanoparticles and lignin. These procedures have significantly improved the effects of placation and pest control in the field. In this sense, our project intends to develop new adsorbent materials based on nanosilica and biomaterials (hybrids) with the capacity to release semiochemicals in a controlled manner. These materials will be synthesized and characterized by several techniques (FTIR, Microscopies, TG, RDX, BET) and tested together with the proven effectiveness. It is intended to produce a prototype of attraction and subsequent elimination of the cotton weevil, so that they can contribute to its population control in cotton plantations.
