Walnut Pest 



T^HF. walnut-husk m.iggot (R/iago/etis 

 -'- suavis Loezv), long known as a dis- 

 agreeable inhabitant of the hulls of the 

 nati\;e black walnut in its eastern range, has 

 demonstrated its versatility by attacking in 

 like manner the English or Persian walnut 

 wherever grown in the East. Some of the 

 infested nuts drop prematurely, whereas 

 others hang to the trees. 



The injury to English walnuts is three- 

 fold since it impairs the quality of the 

 kernels, causes the husk to stick to the shell 

 and blackens and soils the shell, making the 

 nuts unattractive for market. 



Spraying with lead arsenate one and one- 

 half pounds to 50 gallons of water resulted 

 in only 4 per cent infestation at harvest 

 time against 60 per cent unsprayed the pre- 

 vious year. Such treatment, however, can- 

 not be recommended .as a positive control 

 as the flies succumb very slowly to the ef- 

 fects of this poison. 



It is of interest to note that this pest is 

 a close relative of the well known apple 

 maggot, or railroad >vorm. 



A preliminary report on this walnut pest, 

 recently has been issued and may be had on 

 application to the Federal Bureau of En- 

 tomology, Washington, D. C. 



Loganberry growers of Lulu Island, near 

 Vancouver, B. C, recently formed an as- 

 sociation.

 Sitka, Alaska, is experimenting with new 

 varieties of potatoes that m.iy be adapted to 

 conditions in Alaska.

or those receiving applications of three 

 pounds of powdered arsenate of lead in 50 

 gallons of water applied with an engine 

 power melon sprayer, were nearly de- 

 stroyed. Several melon patches were dusted 

 in comparison with the fields sprayed with 

 power sprayers and in no case was this 

 strength of liquid material able to control 

 the beetles, which were unusually num- 

 erous last season. In every case the power 

 sprayers were abandoned in favor of dust 

 in order to save the fields. 



The hold-over protective time was 



greatly lengthened when 5 per cent of 

 arsenate of calcium powder was mixed with 

 a 10 per cent nicotine sulfate dust, since 

 the nicotine dust is very volatile and ap- 

 pears to lose its killing power against these 

 beetles after a very few seconds, under 

 field conditions. 



Since these nicotine sulfate dusts as re- 

 ported by the government were not manu- 

 factured east of the Rocky Mountains

The Importance of Proper 



Moisture Content in 



Boxes 



TJOXES made from seasoned lumber are many 

 •■-j' times stronger than boxes made from green 

 lumber. They hold nails and they stand the test of 

 storage. 



A properly seasoned box means safety and protec- 

 tion for your fruit. An improperly seasoned box 

 leads to loss from loosened nails and rough handling 

 in shipping. 



Exhaustive tests by the United States Government 

 show that I 2 to 15 per cent is the proper moisture 

 content for box shooks. That is the standard of 

 sturdy Westpine boxes. It is maintained by rigid 

 inspection. 



All lumber that goes into Westpine boxes is 

 thoroughly air dried under the atmospheric condi- 

 tions in actual service. Westpine boxes never re- 

 quire re-nailing. 



To be sure your boxes have the proper moisture 

 content which means strength, safety and protection 

 buy tested and inspected Westpine boxes.
