A new, Bt toxin-based strategy for suppression of the Asian citrus psyllid vector of HLB
When the Asian citrus psyllid feeds, it can inoculate the host plant with the CLas bacterium that causes HLB or citrus greening, causing severe damage to the plant. A multi-pronged approach is required for management of this complex citrus disease. One approach to suppress the numbers of psyllid vectors is to use naturally occurring insecticidal toxins that are produced by a soil-borne bacterium, Bacillus thuringiensis (Bt). These toxins are harmless to humans, but are toxic to specific insect species.
