32 SECOND REPORT OF THE STATE ENTOMOLOGIST, 



weak infusion]. The plants should be turned bottom up, placing the 

 left hand over the top of the pot to prevent accident, and then plunging 

 it in the infusion once or twice until the insects drop off. Some of the 

 liquid should always be kept on hand and used on the first appearance 

 of the aphis. After using, the plant must be rinsed in clean water of 

 the same temperature as the room. A florist in Philadelphia kept his 

 plants free from injury in this way without fumigating. 



Kerosene Oil for Scale-Insects on House-Plants. 



Mr. Barker had found the- scale-insects so common on oleanders 

 (probably Aspidiotus nerii and Lecanium hesperidum) and other thick- 

 leaved plants, more difficult to be destroyed. These may be washed 

 with whale-oil soap and water. A sponge dipped in a little sweet or 

 kerosene oil, and wiped up the stem and under the leaves occasionally, 

 will keep off the scale effectually. This had been applied to plants 

 which had been neglected and became very dirty, using the kerosene so 

 freely that there were misgivings of the result, but with only beneficial 

 effects. 



Sulphur for Cabbage Aphis. 



A correspondent of the Hofne Farm, states that after having con- 

 tended for several years with cabbage-worms and lice, and using nearly 

 all the various remedies proposed for them, he has at last succeeded 

 in ridding his cabbages from attack, by a means which he thinks is new, 

 and which he hastens to give to the public. It is simply to sprinkle 

 a little sulphur on the heads of the cabbage when the presence of the 

 insect is noticed. He had applied it three times during the season and 

 '•' deliverance came every time, at once." The sulphur caused the 

 leaves to curl slightly and to discolor a little, where it was distributed 

 the thickest, but it did not check the growth nor otherwise injure the 

 plants. 



Grafe Bagging to Protect from Insect Attack. 



The utility of bagging grapes, is a question not yet settled by grape- 

 growers. Perhaps no general rule can be established, under the greatly 

 varying conditions of soil, culture and exposure of different localities. 

 If the fruit is liable to insect injury, it offers a means of entire protec- 

 tion, at a cost, it is believed, more than repaid, by the attendant benefits 

 of protection from rot, finer color, richer bloom, larger size, etc. 



The principal insect attacks which it would prevent are the fol- 

 lowing named: The grape-seed midge, Isosoma vitis Saunders — a small 

 hymenopterous insect which lays its eggs Upon the grape during the
