hours to allow the bran to take up the 

 arsenic- 



Other powdered arsenicals, such as 

 arsenate of lead, may bo substituted if 

 double the amount is employed. Dry 

 paris green may be used at the same 

 rate as the arsenic. Arsenic is prefer- 

 able, however, because cheaper. 



Scatter the mash thinly along the 



rows or about the bases of the plants to 

 be protected as soon as the cutworms 

 appear. It is better to make the appli- 

 cation well toward evening, or at dusk, 

 since the cutworms feed only at night 

 or on dull, cloudy days, and the bait 

 is more attractive when fresh. If the 

 cutworms should reappear, repeat two 

 or three times at short intervals. 



Experimenting with Ladybugs 



THREE hundred pounds of ladybugs 

 stored at Walla Walla, Washington, 

 during the winter and spring were lib- 

 erated throughout the fruit-growing 

 districts in that section up to June 5 to 

 rid orchards there of aphids. It is esti- 

 mated that these little beetles will com- 

 pletely cover 2,000 acres of orchards 

 and grain fields in that section and de- 

 stroy the aphids. 



In liberating the ladybugs they were 

 taken to the west side of the orchards 

 owing to their well-known habit of 

 traveling eastward, and an observation 

 kept on them showed that they had 

 deposited eggs three days after being 

 turned loose. The eggs hatch out in six 

 to twenty days after being laid, depend- 

 ing on the weather conditions. When 



the larvae appears they are said to be 

 even more rapacious enemies of the 

 aphids than the full-grown bugs. 



District Horticultural Agent E. C. 

 Wood, who has been conducting the 

 experiments in using ladybugs to prey 

 on aphids, has secured some interesting 

 data concerning them. Investigations 

 made in the mountains this spring 

 satisfy him that the ladybugs can be 

 secured there in the spring for a period 

 of about ten days during the month of 

 April. In the fall, he says, they can be 

 gathered for a much longer period, as 

 they begin to colonize in July and re- 

 main in colonies during the winter. 



"There are two very important rea- 

 sons for gathering these beetles rather 

 than letting them come to the valley 



by themselves," said Mr. Wood. "When 

 the beetles are gathered we are able to 

 place them where they are most needed, 

 and again they can be set to work sev- 

 eral weeks earlier than when left to 

 themselves. 



"This beetle is strictly carniverous 

 and does not feed on any vegetation so 

 there is little danger of it becoming a 

 pest, no matter how rapid the multi- 

 plication." 



Plans already are being made by lo- 

 cal orchardists for a ladybug hunt this 

 fall and it is expected that many hun- 

 dreds of pounds of the insects will be 

 stored next fall. 



Experiments in keeping the ladybugs 

 in storage last winter demonstrated 

 that those kept in ordinary storage 

 showed a loss of about one-third, while 

 those kept in cold storage .showed prac- 

 tically no loss at all. 



Tour of Nut Growers Arranged 



A tentative schedule has been ar- 

 ranged for the annual summer tour of 

 the Western Walnut Association through 

 Oregon and Washington walnut and 

 filbert orchards. The tour as now ar- 

 ranged will start at McMinnville August 

 5 at 1 p.m. The first afternoon will be 

 spent in Sheridan orchards, where 

 among other places that will be visited 

 will be that of Professor C. I. Lewis. 

 The morning of August 6 the party will 

 leave McMinnville for Portland, going 

 through Washington County, where the 

 groves of Thomas Withycombe and Mr. 

 Malpas at Gaston will be visited and the 

 Forbis place at Dilley. A number of 

 other stops will be made, including 

 one at Orenco to visit the nursery of the 

 Oregon Nursery Company. 



The party expects to arrive during 

 the afternoon at Vancouver, Washing- 

 ton, where an inspection will be made 

 of the Quarnberg, Norelius and Shaw 

 orchards. Returning to Portland the 

 party will leave that city at 8 a.m. on 

 August 7 for Oregon City, where plant- 

 ings will be visited, and continuing 

 south stops will be made at places near 

 Aurora, Canby and Woodburn. At Canby 

 the Dr. Walgamot nursery will be a 

 point of interest. From Woodburn the 

 trip will be routed to Wilsonville, 

 where stops will be made at the 

 orchards of John DeNeui, H. A. Krause 

 and Dr. Jobse. From this point the 

 route is undetermined and will be de- 

 cided upon when the party reaches 

 Wilsonville. The public is invited to 

 join the walnut men in the tour. Those 

 who decide to do so must provide for 

 their transportation. If they have no 

 car they are advised to arrange with si 

 member of the party who has an extrS 

 seat in his car. 



The summer tour of the walnut grow- 

 ers last year proved to be highly educa- 

 tional to those who made it, the im- 

 promptu discussion that took place iti 

 the orchards bringing out many inter-s 

 esting points about nut growing. 



The Australian deciduous fruit pro- 

 ducers are fast adopting American 

 methods. Their crops do not conflict 

 very extensively with ours, however) 

 and better methods in Australia mean 

 better prices for both. .-»., ,
