INSECTS OF THE BUSH FRUITS 193 



Fruit Worms. — The currant and the gooseberry are subject 

 to attack by certain insects that bore into their fruit. Ordi- 

 narily these insects are not serious, but occasionally the 

 entire crop is damaged by them. The gooseberry fruit 

 worm is perhaps the most serious and is the larva of a small 

 grayish moth. The female lays her eggs on the fruit and 

 after hatching the larvse enter the fruit and feed on the pulp. 

 Occasionally one worm will enter several berries and join 

 all of them by a web. In the small home garden hand 

 picking is perhaps as effective a remedy as can be suggested. 

 This is not practical on a large scale, and some other method 

 still remains to be worked out. 



SPRAYING OUTLINE FOR THE CURRANTS AND THE 



GOOSEBERRIES. 



No, of 



spray. Time of spray. Spray materials. 



First Before buds swell in spring Commercial lime sulphur di- 



luted 1 gallon to .S gallons 

 of water. 



Second Just as leaves are expanding Commercial lime sulphur, 1 



> gallon to 35 gallons of water, 



or 4-4-50 Bordeaux plus 2 

 pounds arsenate of lead to 

 50 gallons of spray. 



Third When fruit is one-fourth grown Same as second. 



Fourth Near ripening season if worms Fresh hellebore or pyrethrum, 



are troublesome on the fruit 4 ounces to 2 gallons of 



water, or dusted on at the 

 rate of 1 pound to 5 pounds 

 of flour or air slaked lime. 



If the aphis or plant louse appears, spray the plants with 

 Black Leaf 40 at the rate of 1 part to 500 parts of water. 

 Any wilted foliage should be cut out and destroyed because 

 this usually indicates the borer. 



REVIEW QUESTIONS. 



1. Name the bush fruits and tell why they are so called. 



2. Differentiate between the several kinds of currants. 



3. How does the currant differ from the gooseberry? 



4. Discuss the propagation of the bush fruits.
