Citrus psylla mainly damages rutaceae plant like citrus, wampee, kamuning, etc. The white honeydew secreted by the insects will result in citrus fuliginous. The adult individuals feeding on plants suffered from citrus huanglongbing can distribute the pathogen in the field, which is one of the most devastating diseases in citrus production all over the world.  


    Currently, chemical control is still the primary method in agricultural production. Allowing for the increasing resistance problem which ails the efficiency of pesticide spraying strategy, which has been employed to control these psylla species for decades, an alternative eco-friendlyapproachis demanded to the Integrated Pest Management (IPM). The Wolbaki Institue for Biological Studies is committed to establish a stable citrus psylla line infected with Wolbachia by embryonic microinjection. The cytoplasmic incompatibility induced by the Wolbachia bacteria can be used to population suppression. A new frontier of Wolbachia and citrus huanglongbing control will be open up.
