Abstract

Bioecology of Planococcus citri (Risso) (Homoptera: Pseudococcidae).

Abstract

The biology of Planococcus citri was studied in coffee plantations in 2 regions in Cuba during 1986-88. Results showed that the insects move on the plant as a response to soil temperature and air humidity below 23°C and 85%, resp. The insects migrated preferentially to the roots but moved to the aerial parts when the above parameters increased. Populations were most abundant from November onwards with a peak in February.
