the effect on some aphids was greater. It is essential to mix nico- 
tine sulphate with soft soap.

The cas eh carers Cole op hora nigricella and C. anat ipenella were 
satisfactorily controlled by nicotine (or nicotine sulphate) and soap.

A satisfactory degree of control was secured by the application 
of nicotine sulphate or derrisol, each in combination with lime-sulphur 
applied early in May. This type of spray is recommended as an emergenc?/ 
measure, if dormant sprays have not been .applied.

Contact insecticides were tried early in the spring when the 
caterpillars were leaving hibernation. Trees were sprayed with 3 lb. 
nicotine sulphate to 8 lb. flour (worked into a paste) and 12 lb. 
milled sulphur, made up with 200 gal. water. After a second applica- 
tion, a great reduction in number of the casebearcrs was noted, but a 
table shows that the control of the codling moth and fruit-tree leaf 
roller ( Cacoecia argyrospila ) is not so effective by this means as with 
arsenicals.

The best method controlling the tineid moth phylloc nistis citre lla 
Stu. (citrus leaf miner) is copious irrigation and drenching the seedlings 
with tobacco decoction (1 lb. to 5-5 gal. water) at int°rvals of 10 days 
or less.
