Many of the materials used attracted more moths to the standard bait 
than when the standard bait was used alone. The materials strongly 
attractive to the adult codling moth may be divided into 3 classes as 
follows: 
"(1) Those whieh, when added to molasses bait in an evaporating 
cup, increased the number of moths caught by 300 percent or more over 
the number of notis captured in molasses bait alone. These included 
safrole, n-butyl sulphide, and pine-tar cil. 
"(2) Those which increased the number of ncths from 100 to 300 
percent. These included citral, dinitrochlorobenzene, isoamyl alco- 
hol, bergamot oil, valeric acid, n-butyl disulphide, beta-methyl 
naphthalene, ammonia, dinitrunaphthalene, geraniol, cymene, mace oil, 
rosin spirits crude, aniseed oil, and 2.6 percent dichlorophenol. 
"(3) Those materials which increased the number of moths from 
90 te 100 percent. These included amyl sulphide, lemon oil, camphor 
oil, pyridine, n-butyl mercaptan, nicotine sulphate, propylene 
dichloride, creosote carbonate, fluorene, bitter almond oil, juniper 
berry oil, diphenylguanidine, amyl alcohol, paranitrochlorobenzene, 
dichloroethyl ether, horsemint oil, paranitrotoluene, eugenol, amylene 
dichloride, and dimethyl aniline. 
"The materials which strongly reduced the number of codling moths 
caught in a molasses bait by repelling the moths or masking or de- 
struying the attractive property of the bait are peppermint oil, 
isobutyl anthranilate, origanum oil, coal-tar creosote, sage oil, 
3.5 dinitro-orthocresol, elemi oil and linseed oil. In all tests 
the addition of nicotine suljhate to molasses bait reduced the num- 
ber of females caught, and increased its attractiveness to males. A 
combination of molasses, bergamot oil, and nicotine sulphate was 
superior to any other combination of these materials in terms of num- 
bers of moths caught. The standard trap was improved by suspending 
a quart bottle of water above the bait te replenish automatically the 
loss of water by evaporation. This addition to the trap not only 
maintained a constant water level near the top of the trap, but it al- 
So required about one half the attention and time to operate. It in- 
creased the catch of moths by 24.6 percent. In a series of tests with 
trees approximately 14 feet high, baits 17 feet from the ground cap- 
tured more moths than did baits 14 feet from the ground. Baits 14 
feet from the ground were far superior to baits 7 feet from the ground." 
Oriental fruit moth parasite stocks freed of mites by exposure 
to low temperature and winds.--J. K. Holloway, of the oriental fruit 
moth parasite project at Moorestown, N. J., has worked out a simple 
and ingenious method of gatting rid of mites in parasite material. 
He says; "For the past two seasons mites have been prevalent in cold
