^ la Capsula del Algodon en Puerto Rico. [The Pink Bollworm of 



Cotton in Porto Rico.] — Porto Rico Insular Expt. Sta., Rio 



Piedras, Circ. 63, October 1921. 12 pp., 4 figs. [Received 23rd

The presence of Platyedra [Pectinophora) gossypiella, Saund., in 

 Porto Rico was ascertained in July 1921. The bollworm now occurs 

 in various parts of the island, infesting the bolls of okra [Hibiscus 

 esculentus], as well as those of cotton. Brief notes on the life-history 

 and habits of this pest are given, together with simple directions as 

 to the measures to be taken by cotton growers.

Le Doryphora [Leptinotarsa decemlineata] de la Pomme de Terre. — Bull. 

 Soc. Agric. France, Paris, liv, no. 8, August 1922, pp. 250-252. 



The Colorado potato beetle [Leptinotarsa decemlineata, Say] has 

 recently appeared in Gironde, the infestation covering an area of 

 nearly 100 sq. miles. Under the Ministry of Agriculture prompt 

 measures have been taken, and arsenical treatment is to be given 

 immediately, not only on the infested area, but also for some distance 

 around it, a sum of about £20,000 at par having been set aside for this 

 purpose. Any fresh infestation is to be notified at once to the Mayor 

 of the district. By regulations published in the Journel Officiel of 

 14th July 1922, no potatoes, leaves, debris or packing of this plant 

 are to be imported from the United States, and the prohibition extends 

 to any other fruit or vegetable on which the potato beetle is found 

 on its entry into France. The organisation of defensive and remedial 

 measures against the pest is outlined, and transport from infested into 

 non-infested areas is extensively restricted. By a decree of 7th July 

 1922, the use of insoluble arsenical poisons on potatoes is permitted 

 up to one week before they are taken up.
