When th is is know n, then th e spraying can be done a t ex actly the rig h t tim e to be m ost effectiv e. To encourage more c er­ ta in m ethods in fig h tin g th e codling m oth, by fin d in g out th e ex act d ate the ad u lts appear, P ro f. T. H. P ark s, of Id ah o , is d istrib u tin g codling moth cages, and in retu rn asks orehardists to carefu lly w atch and m ake note of th e d ate th e firs t and th e la st codling m oth emerges. Each o rch ard ist can m ake a cage fo r him self. The m aterial used is common win dow screen wire, and a co nvenient size fo r the enge is eig h t inches in diam eter b y tw elve or fiftee n inches in length. In these cages place th e larv ae of the codling moth, also place leaves or a b it o f cloth cover fo r shelter, and, when th e moth has actu a lly emerged, it would be well to add tw igs of apple bloom. Secure A verage T em perature, r ia c e the cages in such position in th e orchards as to give an average tem p eratu re. I t is well to throw weeds over th e cage to p a rtia lly hide it, les eening the pow er of th e sun. Since ten c e n ts ’ w orth of m aterial will make a cage, it is well to have tw o or three of them placed under varied conditions. The w riter places three d iffe re n t cages in v ary in g conditions in th e orchard. As th e larv ae o f th e codling moth em erges from au apple in late fall, it seeks a place to w in ter w ith safety , w in terin g as larv ae or worms. These larv ae may w in ter under a b it of rough bar'i. on th e tru n k o f a tre e or in any sim ilar a ielter. T hey are usually ab u n d an t about packing houses. As the larv ae seeks shelter, it w eaves over itse lf a th in web. H ere it reposes u n ­ til springtim e. The next step depends on th e char a c te r of the season and on th e earli- ness w ith which its place of conceal nient may warm up. D epending on the e h aracter of th e shelter, th e d ate of p upation may v ary fifte e n to sixty days, or more. The next step is fo r tho la rv a e to change to th e pupae form , called p u p atin g In fool w eath er it re m ains in th is form f r tw en ty one d ay s; in the heated summer a less time, and then em erges us a codling moth.

F. lln rst. who has given very carefu l study to th e h ab its of th e rod lin g moth in Idaho, rep o rts th a t th e la rv a e may feed one to tw o days on th e foliage before en terin g th e apple.

Thia poison lodged w i t h i n the calyx m ay poison n o t only $82 th e larv ae of the firs t, b u t some of the second brood, since the poison rem ains in position to in tercep t th e larv ae when­ ev er it does enter. E ggs on Leaves. A skillful o rchardist does not spray un til a fte r pollination has tak en place and the m ajor portion o f th e |>etals have fallen. In th e Y akim a d istric t in a favorable season, th e rule is to begin to spray when eig h t-ten th s of th e petals have fallen. A fter th e p etals fall there is usually fiv e to seven d a y s ’ tim e in which to spray before the calyx closes so tig h tly as to p re v e n t th e lodgment of th e poisonous spray. This firs t calyx sprav should he w ith high p res­ sure, aim ing to force th e liquid into the portion of th e ealyx cup. Since the eggs of the codling m oth have not yet been deposited and may not be de­ posited for some weeks a fte r th is sp ray ­ ing, th e object of th is firs t spray is to securely lodge th is poisonous liquid in th e calyx of each apple oil th e tree. C areful observers, like Mr. H urst, note th a t most of th e eggs of th e cod­ ling moth are deposited on th e leaves, and th a t th e vonng larv ae m ay feed a little on th e leaf before seeking the apple. This gives an opportu n ity to in tercep t th e larv ae by the second sprav, which th is tim e should bo a fine m ist, coating the under and upper sides of th e leaf. M oth Cage Is Aid. To determ ine th e best tim e fo r the second spray is th e object of th e moth cage, the careful observation of w hich ascertain s when th e moth will be ready to lay eggs and thus determ ine th e tim e for the second sprav, which should coat the leaves ju s t in advance o f th e lay in g of th e eggs.
