INSECTS INJURIOUS TO VEGETABLES 



Injury appears to be practically due to the later-appearing gen- 

 erations, and more especially to muskmelons raised for north- 

 ern markets. In September, 1897, fields of cyniblins cultivated 

 in Maryland, Virginia and the District of Columbia were 

 badly damaged or totally destroyed by the pickle worm, but 

 in the after years the insect has almost entirely disappeared. 

 The life history and habits of this species have been studied

by Prof. A. L. Quaintance, in Georgia. Larvie are first noticed 

 there about the middle of June. Eggs are deposited on the 

 flowers, buds, or tender portions of a plant. The larvae first 

 eat out cavities in the leaves or stems, the angle between a leaf 

 and stem being a favorite place of entrance. Frequently they 

 enter flower buds, and have been found by the writer destroying 

 many prospective cymblins in this manner. With the second 

 stage, at least southward, the larva; feed on the young fruit, 

 and as they mature they pass from plant to plant and thus 

 injure for sale much of the fruit affected. They void large
