ure almost one-half inch in length. The 

 eggs are white to yellowish, elongate 

 oval in shape. The moths of the last 

 brood deposit eggs late in August and 

 September in crevices and rough places 

 in the bark. When the eggs hatch, usu- 

 ally in about five to seven days, the 

 young larvae dig small cavities in the 

 bark at the base of the new wood, 

 usually at the crotch of the limb where 

 the winter is passed. The hibernating 

 quarters can be found upon close exami- 

 nation (high power lens usually re- 

 quired), as indicated by small reddish 

 brown mounds of chewed bark, and in 

 some cases may be webbed together by 

 bits of web. As spring advances the 

 larvae begins feeding on the surround- 

 ing tissues and reach the surface in 

 from ten to fourteen days. The young 

 larvae immediately attack the buds, de- 

 stroying young fruit and burrowing 

 down the pith' of the tender shoots, 

 causing them to wither and die as the 

 season advances, thus necessitating the 

 uninjured buds below to send out an- 

 nual growth. The same larvae will de- 

 stroy a large number of buds each sea- 

 son, also a number of twigs. 



When full grown the larvae crawl to 

 the larger branches or the trunk, where 

 they construct very loose cocoons con- 

 sisting of a few threads of silk. Here 

 the pupae period lasts from ten to

twelve days. The moths emerge and 

 deposit eggs on the new twigs near the 

 base of the leaves. When the eggs hatch 

 in probably ten days the larvae feed on 

 the tips of the young shoots and at- 

 tack the fruit and eat out a consider- 

 able cavity in the flesh which usually 

 fills with gum. They sometimes eat in 

 the seed and destroy the kernel. The 

 second brood reaches maturity in July 

 and August and pupate in the basin of 

 the stem end of the fruit. The third 

 brood moths deposit their eggs as a rule 

 around the insertion of the stem. This 

 brood of larvae usually feeds entirely 

 on the fruit. 



Control Measures 



USE LIME sulphur, winter strength, 

 5 degrees baume in tank 200 gal- 

 lons, adding arsenate of lead paste No. 

 8, or arsenate of lead powder No. 4. 

 The lime sulphur kills most of the hib- 

 ernating larvae and the lead is designed 

 for poisoning the remainder at their 

 first feeding. 



As damage is just now appearing in 

 the warmer sections along the Snake 

 river, prune and peach growers should 

 lose no time in fighting this pest. For- 

 tunately this spray will control San 

 Jose scale and brown mite or so-called 

 red spider. The arsenate of lead, how- 

 ever, is of no value for these two pests, 

 but will do no harm.

Absolutely No Bruising of the 

 Fruit by Using the 



Ideal Fruit Grader 



It is built for two, three and four grades, and room 



for four, six, and eight sorters to work at one time. 



The machine can be adjusted while running in about 



one minute of time. 



It is the most simple machine on the market, never gets 



out of order, as there are no complicated parts to get 



out of adjustment or break. 



We have placed our new sorting table on this year s 



output which increases the amount of fruit that is 



packed per day. 



It is noiseless in operation. Nothing to break, as the 



fruit is graded by coming in contact with elastic bands 



only. 



We will be pleased to mail you our folders and prices 



of our several size machines upon application. 



Our literature explains the working parts in detail, also 



shows several different views of the machine.
