[C. parahyhensis in the Coffee Plantations of the State of Para- 

 hyba.] — Chacaras e Quintaes, S. Paulo, xxv, no. 1, 15th January 

 1922, pp. 28-30, 3 iigs. 



A withering of coffee bushes in the State of Parahyba, first attributed 

 to soil impoverishment and weather conditions and then to infestation 

 by a Coccid, Cerococcus parahyhensis, Hempel, has now been traced 

 to faulty cultivation. This scale appears to be peculiar to coffee in 

 Parahyba, and assists in destroying weak plants on which it occurs in 

 large numbers. Owing to the wax coating, insecticidal sprays are 

 ineffective against it, and scrubbing the stems is advised. 



C. parahyhensis flourishes during the rains, but inspection in October, 

 in the dry season, showed that a high mortality occurs, due apparently, 

 in part, to Hymenopterous parasites.

 usual in the United States, and gives no new information.

American " tanglefoot " is recorded as most effective for banding 

 fruit trees against Cheimatobia {Operophthera) hrumata and Hybernia 

 defoliaria. About 1 lb. is sufficient for twenty trunks of average girth.

The presence of Briichus [Acanthoscelides) ohiectus was first observed 

 in small numbers at Vienna in 1918. In 1919 the beetles were more 

 numerous, and in 1920 the bean crops were seriously infested by this 

 pest.

Thousands of young pine trees have been destroyed in Uruguay by 

 Pissodes notatus. The larvae of this weevil were found in September 

 1920, the first pupae being noticed on 18th September, and the 

 adults emerging on 6th October. There appear to be two generations 

 a year in Uruguay.
