REPORT ON INSECT AND FUNGUS PESTS OF 

 PLANTS IN 1918. 



The second of a new series of Annual Reports on the distribu- 

 tion of insect and fungus pests of plants in England and Wales 

 has just been published by the Ministry. It has been chiefly 

 compiled from the records contained in Monthly Reports sent in 

 by qualified observers stationed in different parts of the country, 

 and it forms a comprehensive survey of the distribution and 

 economic importance of plant pests during the year 1918. The 

 Report is somewhat technical in character and is intended 

 primarily for scientific workers on plant diseases and perhaps even 

 more for those who will be engaged in this work in future. In 

 addition to notes on the most important pests the Report gives 

 the records in tabular form, so facilitating reference. For the 

 convenience of readers weather charts have also been added.
