Hsieh, F.K., & Hwang, J.S. 1983 [Further studies on the control of the lac insect (Kerria lacca (Kerr.)]. Plant Protection Bulletin (Taiwan) 25: 31-40.

Notes: Experimental results showed that emulsive spraying over the longan or litchi trees was more effective against the lac insect, Kerria lacca (Kerr.) as compared to granular treatment of the root zones, or painting insecticides on the tree trunks. Results consistently indicated that the timing of the application of the chemicals was extremely important. Treatments applied at the 1st-2nd nymphal stage were more effective than those applied at the adult stage. Recommendations for chemical and mechanical control were made as well as effective timing of treatments.
