man told me he had driven them from his vineyard by burning pieces of oia rubber 

 between the rows. The manufacturers are responsible and claim Nicotina to be the 

 best insecticide in the world. The sample 5 pounds was sent mo to try and report. —

Another Letter. — T received a line from you last year to try the Bordeaux Mixt- 

 ure. We have had no rot or mildew, but have something just as bad, that is, the Rose 

 Bugs. They have stripped a good many large vineyards this year. I have been 

 spraying about 18 acres out of 20 with good results. I used lime-water as strong as 

 I could use in the spray pump, about 1 bushel of unslaked stone lime to 50 gallons of 

 water and 1 pint of crude carbolic acid. Two acres that I did not treat gave an en- 

 tire loss of fruit. Our apples, pears, and peaches are an entire failure this year on 

 account of late frosts. The clay lands south of us were troubled with the black rot 

 last year; the Rose bugs are confined mostly to the ridge land. I have tried London 

 purple and Paris green and Hellebore without any effect on them. Some have used 

 the dry lime, but the solution is far better. Will give you the results at the close of 

 the season if you desire it. I have made a specialty of fruit for forty-six years. The 

 lime does not kill the Rose bug, only prevents it from eating. If there is anything 

 that will kill them let us know before another year. I tried the same formula on 

 ^ne-half of my cherry-trees, saved a good crop, while the half not treated did not 

 have a cherry left— a good test. — [S. Justus, Mentor, Lake County, Ohio, June 22, 

 1890, to B. T. Galloway. 



Reply. — Your letter of June 22, with specimens, duly received and referred to this 

 Division by Mr. Galloway. This insect has been fully discussed in a recent number 

 of Insect Life, a copy of which has been sent to you. The lime-water treatment 

 which you report as being very satisfactory, is one of the more efficient of the reme- 

 dies against this insect. Other remedies of even greater value are mentioned in the 

 article referred to, but they are all of little avail against an exceptional onslaught. 

 We shall be pleased to receive the report of the results of any other experiments 

 you may make. — [June 25, 1890.] 



Wire -worm Damage to Onions. 



I send by to-day's mail a small box containing some worms that are doing a great 

 amount of damage to the onion crop in this part of Washington (w. st). I found a 

 number of the onions turning yellow and found the worms working on the plants 

 below the surface, from one to four worms at each infested plant. If you could give 

 us the name and tell us the best way of destroying them you would be doing us a 

 great kindness. — [Nicholas Vipond, Minter, Pierce County, Wash., June 18, 1890. 



Reply. — I beg to acknowledge the receipt of yours of June 18, together with the 

 accompanying larvse found infesting onions. The larvae belong to the click or spring 

 beetles, the particular species of which can not be determined from the larvse, as the 

 latter are scarcely distinct in allied forms. The larvse sent, however, may be referred 

 to the genera Drasterius and Agriotes. The larvse of the family Elateridse, which in- 

 cludes the genera mentioned, are the well known wire- worms, which are known to 

 injure a large number of cultivated crops. The beetles, however, may be trapped 

 successfully before they have deposited their eggs in the spring by means of poisoned 

 bait. Professor Corastock, of the Cornell experiment station, has obtained excellent 

 results by using the same remedy which I found so effectual for cut-worms, i. e., by 

 taking bunches of clover dipped in a moderately strong solution of Paris green or 

 London purple and placed at different parts of the infested fields. These baits 

 should be renewed once or twice a week during the early part of the summer, or the 

 period during which the eggs are deposited. — [June 25, 1890.] 



Orange-tree Bark-borers. 



Since the freeze last winter which killed so many of our orange trees a great many 

 bugs are boring into them, mostly into the dead wood, but some into the sound wood.
