Insects pests recorded include wireworms and white grubs doing 

 considerable damage to maize and other cereals, sugar beet and onions ; 

 the strawberry sawfly {Empria ignota), controlled in two fields by 

 spraying with hellebore ; the melon aphis {Aphis gossypii), which 

 caused a loss to melon growers of £3,000 and did much damage to 

 cucumbers ; the cabbage root maggot {Chortophila {Pegomyia) brassicae) ; 

 the onion root maggot, Hylemyia antiqua (P. ceparum) ; the onion 

 thrips {Thrips tabaci) ; the tobacco worm [Profoparce iPlilegetJiontius)

 of Datura stramonium. 



Insects attacking fruit-trees were : — Codling moth {Oydia pomonf^Ua); 

 plum curculio {Conotrachelus nenuphar) ; San Jose scale {Aspidiotus 

 perniciosus) ; tent caterpillars {Malacosoma americana and M. disslria);
