Summary of lecture
Sustainable Pest Control for Citrus Production in Brazil
Brazilian growers generally have their mind set for the use of chemical pesticides, usually making an excessive, abusive use of chemical for insect pests and diseases control in Citrus groves. However, alternative technologies have become available to them, allowing the successful implementation of Integrated Pest Management (IPM) strategies in Brazilian Citrus groves. IPM strategies have greatly benefited from the use of sex pheromones and biological control agents. The sex pheromone of the citrus fruit borer was synthesized early in 2000, and has brought tremendous economic return with its use in 12% of total Citrus producing area. Ageniaspis citricola (Hym.: Encyrtidae) was imported in 1998, mass-produced and released in several areas of the state of São Paulo, providing successful control of the Citrus leafminer (CLM). This parasitoid became established in several climatic regions of the state, currently providing a natural control of the pest. The sex pheromone of the CLM has been identified and will become available to growers as a new tool in a near future. More recently, mass-rearing procedures of the Asian Citrus Psyllid (ACP) parasitoid, Tamarixia radiata (Hym.: Eulophidae), were established, and a new approach for the use of the natural enemy has been put in place to reduce the natural populations of Diaphorina citri. There are also other components under investigation/ development, as the use of microbials for ACP control. Investigations on the side effects of pesticides are under way to provide growers with alternative strategies for pesticide utilization.
