Insect Pests. 237 



•on the south, and southwest sides of the trunk from the 

 ground to the branches. No borer will deposit her eggs iti 

 the shade, and this shading if well done not only blocks her 

 little game, but promotes the flow of sap, thus saving many 

 a feeble tree and helping the gowth of all. 



Of currant worms we have two, both of the saw fly 

 family. One a native, a light green little fellow half an 

 inch long, always hungry, and not conteat with what one 

 generation can do sends out a later brood to gather in what 

 tender leaves may have grown after the work of the first 

 brood. 



The other is a foreigner, and was first noticed about thirty 

 years ago, but is now wide-spread and more destructive 

 than the native. He is larger, darker in color and dis- 

 tinctly marked with black dots. Soon after the leaves are 

 formed their small white eggs are laid singly in rows along 

 the leaf ribs. These hatch very soon, and the little worms,, 

 almost too small to be seen, eat round holes through the 

 leaf. These holes are the first hint you will have of their 

 presence and Just then is the time to " go for them " look for 

 these indications in the central parts of your bushes, very 

 rarely at the top or outside. 



Paris green or Loudon purple will do the work, but is too 

 dangerous. Powdered vvhite hellebore is the best medicine. It 

 can be applied with water, but I have always done best work 

 with the dry powder, using a one-pound baking powder can 

 with cover punctured with fine holes, and sifting the helle- 

 bore on in large or small quantities as needed. A very 

 little does the work, and slight practice will enable one to 

 apply without much waste. 



Some dilute with flour or plaster, but from those, I think, 

 come most complaints of failure. 



Three things are important: Keep the powder from your 

 nostrils and lungs; apply early, before the worms have 

 done much damage watch carefully for the few that are 

 missed in the first application. 



The remaining fruit depredators are not in large num- 

 bers — are only slightly harmful, or are easily destroyed, so 

 we leave them.
