In the province of Jaen fumigation against Phloeothrips oleae was 

 continued. Dacus oleae was one of the olive pests that have contributed 

 to a small crop.

This article briefly describes Platyedra gossypiella, Saund., and its 

 habits. Its distribution is recorded and reference is made to Order 

 No. 80 of the Dominican Republic, the provisions of which recognise 

 the possibility of this pest being introduced in cotton seed. A good 

 quarantine law is needed in Dominica.

Pvrethntm cinerariaefolium, from which pyrethrum powder is made, 

 is produced almost entirely in Dalmatia, Montenegro and the Adriatic 

 Islands. The method of its cultivation is described. 



The usual formula for pyrethrum-soap solution is l|lb. pyrethrum 

 powder, with 2 lb. black soap to 10 gals, of water ; but, however finely 

 this powder is ground, it always blocks the jets of the sprayers ; 

 attempts are therefore being made to extract the oleo-resin of the 

 pyrethrum by means of solvents such as alcohol, ether, or carbon 

 tetrachloride. The liquid obtained is concentrated by distillation, 

 the soap extract is then added, and 1 part of the mixture is mixed 

 with 9 parts of water before use. Attention is drawn to the fact that 

 the production of this insecticide would be easy in Algeria, that there 

 would be a demand for its exportation, and that it is to the interest 

 of vinegrowers, as well as profitable to them, to cultivate the plant.
