The experiments in 1921 show that the larvae that cause the deep 

 work in the apples and that live over the winter may be killed by the 

 use of 5 lb. lead arsenate to each 50 U.S. gals, spray, appHed at the 

 time oviposition is about to begin. 



The proper time for the application of the second spray will vary 

 each year, In Niagara the moth usually begins to oviposit about 

 fhe middle of June, but is of little consequence till the evening tem- 

 peratures are 60° or above for a series of days. This occurs about 

 the first of July on the Ontario Plain, and in central New York and the 

 Hudson Valley about the middle of June, just when the moths are 

 emerging. The proper way to gauge the w^ork is by means of the 

 information secured through oviposition records.

Most of the information here given concerning the Mexican bean 

 beetle [Epilachna corrupta, Muls.l has alreadv been noticed \R.A.E.,

The danger of the introduction of this pest into Mississippi and the 

 need for continued vigilance and the adoption of measures to prevent 

 its spread are emphasised.

Pseudaonidia duplex is recorded from three different properties 

 in Mississippi. As soon as the scale is found, all plants on the infested 

 property are carefully in.spected, and the owner's consent obtained 

 to burn all those found to be infested. This scale has been found 

 on more than a hundred different food-plants in the United States. 

 The public are being warned through the press of the danger of 

 introducing this and other pests by bringing uninspected plants into 

 their homes, and other preventive measures are being adopted.
