Notes on the insecticide use of the gasoline blast lamp, S. A. FoKtJEs (7///- 

 noinSla. Bill. S9, pp. 145-154)- — The literature relating to the use of the gasoline blast 

 lamp in the destruction of insects is briefly reviewed. It appears that this aj)paratus 

 has been used in combating harle(iuin cabbage bug, San Jose scale, cotton-boll 

 weevil, aster beetles, chinch bugs, scale insects, caterpillars, fungus diseases, etc. 



A number of experiments were made, and a report is given upon the same, by E. 

 S. G. Titus. It api^ears from these experiments that a modified form of gasoline 

 torch, very similar to the ordinary plumber's torch, when under the greatest possi- 

 ble pressure gives a flame with sufficient heat to singe hair at a distance of 10 to 12 

 in. The effect of this heat was tested on scurfy scale, Forbes scale, woolly aphis, fall 

 webwonns, meadow moths, various caterpillars, including cabbage worms, etc., and 

 also on lilac mildew. At the same time tests were made to determine the tolerance 

 of the leaves of various plants for the heat of the torch applied for varying periods.
