Fio. 22. 



on the cucumber and melon vines, is often the cause of great 

 vexation to the gardener. 



NATURAL HISTORY. The larvae (1, Fig. 22) feed on the roots 

 and underground stems, inuture in about 

 a month, pupate in the ground, in which 

 state they continue about two weeks, 

 when the imagos appear. There are two 

 broods a year, and may be three. It -r 

 passes the winter in the pupa state. The \ 

 first imagos of the season attack the young 1 

 vines, and in a single day may destroy 

 them utterly. The later insects do not 

 do so much damage, as the vines, from 

 increased growth, are able to stand the 

 attack. 



REMEDIES. Boxes covered with glass or millinet and placed 

 over the vines are sure protection, providing the beetles do not 

 get inside. If glass is used, care must be taken to shade from 

 the hot sunshine, or the plants may be ruined. These will form 

 miniature hot-beds, and will hasten growth if rightly managed. 



Paris green is a certain preventive, and in careful hands is 

 harmless to the vines. I have used this remedy with the very 

 best success. I would put one part green to eight parts flour, 

 apply when the vines are dry, and add just as little as I could 

 and see it on the vines. Add a little too much, and the vines 

 are sure to be killed. The past summer I found that the kero- 

 sene and milk, one to ten, worked well in combating these 

 insects. 



The Codling Moth. Carpocapsa pomonella, Linn. Family, 

 Tortricidce. Order, Lepidoptera. All will concede that this 

 insect holds first rank among our insect pests. 



NATURAL HISTORY. The little gray moths (Fig. 23,/andy), 

 come forth in May and June, are wholly nocturnal, and therefore 

 seldom seen. As soon as the fruit forms, a single egg is laid 

 on the blossom end of the fruit (Fig. 23, #), and as soon as the 

 egg hatches, the larva (Fig. 23, c] enters the apple. All know 

 the subsequent history of the larva in the fruit, for who has
