Conteúdo: | The control of pests in agricultural systems is currently based on the widespread use of pesticides that efficiently control pests but have negative effects on the environment and humans. Thus, several studies have been conducted to develop alternative sustainable ways to control pests in agriculture. The use of semiochemicals presents a good alternative to develop a sustainable tool monitoring and control insect pests in crops areas. The dispensing carriers of semiochemicals are typically made of non-degradable material, often petroleum derivatives such as butyl rubber, that become polluting waste after application. To develop a biodegradable and low-cost dispenser for semiochemicals, particles of CaCO3 and a CaCO3/Kraft lignin composite were synthesized using CO2 bubbling, characterized and evaluated for 30 days as a dispenser of the limonene molecule, which is a common semiochemical in plants and also pheromone component is some insect species, such as the lesser mealworm Alphitobius diaperinus. Furthermore, limonene is volatile molecule that is easy to acquire and low-cost, which makes it an ideal semiochemical to evaluate the potential of the CaCO3 particles and CaCO3/ Kraft lignin composite as a semiochemical dispenser for use in agriculture. The pure calcium carbonate I, pure calcium carbonate II, and composite I synthesized particles presented a larger specific surface area than the other composites. All the particles evaluated showed a slow limonene release rate between the 5th and 30th days evaluated, indicating the potential of these materials as pheromone dispensers. The composites with higher specific surface area, calcium carbonate II (19.5 m2/g) and composite I (23.1 m2/g), released a higher level of limonene during the 30 days evaluated.
