Tylenchina Tylenchoidea Pratylenchidae Pratylenchinae Pratylenchus coffeae
India; tropics; southeastern US; Central and South America, Caribbean, Zaire..
C-rated pest in California pending current initiatives to have it elevated to an A rating.
The first report of P. coffeae was by Zimmerman in 1898. He reported that the nematode was responsible for destruction of 95% of the Coffeae arabica plantations in Java.
CDFA Interception Records for Pratylenchus coffeae in California (Courtesy of J. Chitambar, CDFA):
1952 – 1972: Detection of P. coffeae within California is summarized in Siddiqui, Sher, and French (1973). The nematode was found in association with ornamentals, strawberry, cherry, and raspberry plants in 175 Nursery (land or greenhouses), 22 Urban (residential properties, golf courses, parks), and 1 Commercial (cultivated fields and orchards) samples collected throughout the State.
Siddiqui, Sher and French (1973) obtained much of their information from UC Berkeley, UC Riverside and UC Davis nematode distribution records, as well as identificaton records maintained by certain County Agricultural Commissioner offices and the CDFA Nematology Laboratory.
1973 – 1999: P. coffeae was detected in 223 Quarantine samples (originating outside California), 32 Nursery samples (field-grown or greenhouses), 2 Commercial samples (cultivated fields and orchards), and 27 Dooryard/residential samples.

Males and females present.
Causes death of coffee plants in nurseries.
3 million dollars are lost annually to damage in coffee crops in India.
Nematicides are effective; resistant rootstocks available for coffee.
Note: Citrus rootstocks resistant to Radopholus similis in Florida are susceptible to infestation by P. coffeae.
