CROP PRODUCTION 



Just after the fruit sets tie paper bags over some of 

 the clusters, and leave on till the grapes are ripe. 



Insect Enemies 



Look for grape leaf hoppers on the leaves. Find the 

 different stages. See how they get their food. 



Look also for grape-vine flea-beetles. See how they 

 differ from the leaf hoppers. 



Find clusters of green grapes attacked by the larvae 

 of the grape-berry moth. See the whitish worm that 

 does the damage.
