178 INJURIOUS INSECTS OF 1904. 



emerge on September 7th. The young caterpillar, on emerging, is 

 purplish, with eight stripes running along the body. Later it be- 

 comes duller colored, and about midway of its length the color is 

 such as to make that part appear diseased. The presence of this 

 borer in a stem is indicated by a drooping and wilting of the grow- 

 ing tip and examination will disclose a round hole on the surface 

 of the stem, below the wilted portion, the opening of its burrow. 

 The affected stem can be cut ofif just below this hole, and the 

 "worm" in its burrow be killed ; or, in rare cases a slitting of the 

 stem on one side, above the hole, with a penknife will bring the cul- 

 prit to view. If it is not found in the burrow above the hole, one 

 must note whether any part of the burrow is in the stem below the 

 hole; if so, the caterpillar must be sought for there. If these pre- 

 cautions are taken at the very first appearance of the drooping of 

 the plant serious injury may be prevented, and further trouble by 

 these worms turning into moths and laying more eggs, averted. In 

 stems which are straight, offering no irregularity in growth, a flex- 

 ible wire may be run up in the burrow, or down through the open 

 ing, and the caterpillar killed in this way. Most feasible af all, pos- 

 sibly, is the method hit upon by a Minneapolis party whose choice 

 tomato vines were being injured. With a medicine dropper he 

 injected into each hole about one teaspoonful of chloroform, imme- 

 diately plugging the hole with a bit of cotton, that the fumes might 

 be retained. This worked like a charm, did not appreciably injure 

 the tomato plant, and would doubtless be effective upon flowering 

 plants. We have suggested the use of bisulphide of carbon in place 

 of chloroform on the ground of its being less expensive, and have 

 been informed that it has been found quite as successful as the 

 chloroform. 



Cabbage Worm: This vegetable garden pest finds also food to 

 its liking in the flower garden. The writer had a fine growth of 

 nasturtiums last season, which, in late summer, were badly eaten by 

 the larvae of the white cabbage butterfly. We resorted to hand 

 picking. See in this connection the remedial measures discussed 

 on page 174. 



Rose Beetle, Rose Chafer, "Rose Bug": This yellowish beetle, 

 being a leaf eater, can be easily killed by an application of some 

 internal poison, like hellebore. By jarring the bushes in the morn-
