Research and Development of Citrus in Taiwan
Control of citrus psyllid, Diaphorina citri Kuwayama has been emphasized because it is a vector of citrus likubin which seriously threatens the citrus industry of Taiwan. Tamarixia radiata (Waterston) was introduced from Reunion by Taiwan Agricultural Research Institute and evaluated its efficiency against citrus psyllid from 1983 to 1990. The results showed that the introduced parasitoid T. radiata has the ability to depress the population of citrus psyllid which did not disperse actively on jasmine orange when the host environment is stable. Therefore, we suggested to maintain a stable jasmine orange situation by avoiding large scale pruning and insecticide spraying to provide suitable habitat for T. radiata and the native wasp Diaphorencyrtus diaphorinae (Lin & Tao). However, It is not practical to use parasitoids in orchard due to the following reasons: 1. a single citrus psyllid carrying the pathogen can transmit likubin; 2. parasitoid activities are seriously limited by discontinuous budding period and the insecticide application; 3. the citrus psyllid is easily controlled by chemicals; 4. and insecticide application is necessary for citrus cultivation. Therefore, we suggested to use cultivation systems and insecticides without parasitoids for the control of the citrus psyllid to reduce likubin transmission in citrus orchards.
