very small, and the danger of the large outbreak that was expected did 

 not materialise ; there was consequently no need to utilise the extensive 

 preparations that had been made for the campaign. These causes 

 were also resj)onsible for the decrease in the numbers of Locusta 

 tiiigratoria in some places, as well as of some other insects, which, 

 in the absence of locusts, were destroyed by birds to a greater extent 

 than usual. 



The drought however favoured the increase of Tetmn/jchus, which 

 has done considerable damage to cotton, and of the cabbage and the 

 cotton Aphids [Aphis brassicae and A. gossypii]. The frost in April 

 destroyed a number of insect pests of orchards, and a considerable 

 reduction in the numbers of Cydia pomonella, C. funebrana, KJiynchites 

 auratus and of Hypera {Phylononms) on lucerne is to be expected next 

 year.
