weeds, etc., immediately after liarvest, and then cnltivnting the land 

 and allowing no grass or grain crop in the field the following year, is 

 advised. It is recommended that badly infested wheat and oats be cnt 

 while green and used for hay. A lady beetle {Ulppodamia convergens), 

 syrpbus flies, and several hymenopterous parasites were found to reduce 

 greatly the numbers of the lice. An illustration from a micro-photo- 

 grai)h is given showing an Aphidius parasite in the act of emerging 

 from a dead grain aphis. 



The pear-leaf blister (pp. 9-12). — Brief notes on the appearance and 

 life history of Phytoptus purl and the injury caused by it to the foli- 

 age of fruit trees. It has been found to be quite common in Oregon, 

 and illustrations are given showing the damage done to leaves and 

 an enlarged figure of the insect. Pruning and burning the infested 

 branches and spraying with kerosene emulsion in the autumn when 

 the mites are migrating are recommended. 



The clover mite (pp. 12, 13). — Notes on BryoMa pratensis, which is 

 found to be quite prevalent in Oregon, where it infests several kinds 

 of fruit trees in addition to clover and grasses. It is recommended that 

 infested fruit trees be sprayed with kerosene emulsion to which a little 

 sulphur has been added. 



KoebeWs resin icash (pp. 13-15). — Notes on the preparing of a resin 

 wash, 4 lbs. of resin, 3 lbs. of carbonate of soda, and 1 gal. of water 

 being boiled together until the resin is dissolved, and then 4 gal. of 

 warm water added. One part of this wa sh to 6 parts of water is recom- 

 mended for the woolly aphis, and 1 part to 10 or 12 parts of water for 

 other plant lice and the mealy bug. Experiments were made on plum 

 trees infested with hop lice by spraying them with different strengths 

 of the wash. One part of the wash to 15 parts of water destroyed the 

 lice, but did not injure the larvai of the syrphus flies or lady beetles that 

 were preying upon the lice, and this strength is then recommended for 

 use against these aphides.
