Pheromone-Based Psyllid Control Not Viable
Studies with psyllid pheromones show that the insect’s behavior is altered when it is infected by the HLB-causing bacterium Candidatus Liberibacter (CLas). This makes it difficult to produce a commercial psyllid-control product based on the insect pheromone, Brazil’s Fundecitrus has concluded. “The sexual pheromone is an attractant produced by the female of the species, which promotes behavioral changes in male …
