selected for the experiment, and one was sprayed 6 tunes wifh arsen- 

 ical mixtures, once with London purple, and 5 times with Paris green, 

 the applications beginning in July and continuing until after August 

 27. The adjoining tree was left untreated as a check. The apples 

 which fell to the ground from both trees were picked up on 5 difiereut 

 <lates and examined with relerence to injuries by the codling moth and 

 rot. From the sprayed tree were examined 834 fallen apjiles, of which 

 only 19 ])er cent were free from rot. Of the rotten apples 67 per cent 

 were injured by the codling moth, while 82 per cent of those not rotting 

 were infested. Of the fallen apples from the check tree 27 per cent 

 were rot free, of which 96 per cent were injured by the codling moth, 

 while of the rotted apples but 92 per cent were damaged. Eight hun- 

 dred and seventy-four apples were picked from the sprayed tree, of 

 which 68 per cent were damaged by the codling moth, while of 816 

 apples picked from the check tree 81 per cent were injured by the 

 insect. 



The conclusions drawn are in favor of spraying with arsenicals for 

 the moth, though the rot fungus is apparently not affected by the 

 application. It is believed from the evidence that the codling moth 

 avoids rotting apples. Apples from the sprayed tree were carefully 

 analyzed by the chemist of the station, but no perceptible quantity ol 

 arsenic was discovered. 



Insecticides, A. N. Caudell (OMahoma Sta. Bui. 15, pp. 29, 30). — 

 Notes on experiments against the squash bug {Anasa tristis) with vari- 

 ous insecticides, using a combination of pyrethrum powder and kero- 

 sene emulsion, and also some odoriferous substances, namely, emulsions 

 of the oils of tansy, cajeput, savin, and eucalyptus. Dusting the plants 

 with lime and pyrethrum was also tried, but none of the remedies were 

 effective.

 (Anthrenus scrophularke), pitchy carpet beetle {Altagenus piveus), and clothes moths 

 (Tinea pelioneJla, T. biscUieUa, and T. iapetzella). Benzin and bisulphid of carbon are 

 recommended against all of the species.
