New York AGRICULTURAL EXPERIMENT STATION. 361 
Another plum was immediately put in place of the one removed, 
remaining until June seventeen and then examined, with about 
the samt result as No. 1. 
Next, two plums were put in the same bottle and left until the 
_ twenty-first ; on being removed it was found that the curculio had 
deposited ten eggs in one, and eaten two holes, the larger of 
which measured .19 by .12 of an inch, and .1 of an inch deep, and 
the smaller .12 by .06 of an inch and about .07 of an inch deep. 
In the second nine eggs had been laid, but no part of the plum 
had been eaten. 
These were replaced by another plum on the twenty-second ; 
forty-eight hours after it was put in the bottle an examination 
_ showed eight eggs deposited and two holes eaten in the fruit, one 
17 by .1 inch and .07 of an inch deep; the second .13 by .07 
inch and .03 of an inch deep. 
_ This was again replaced with afresh fruit. This was taken out 
on the twenty-fourth, forty-eight hours intervening from the time 
- if was put in, as in the last case cited. In it were found five eggs 
and a pit .23 by .13 inch, and .1 per cent of aninch deep. On 
_ the twenty-fourth, after removing the above, the seventh and last 
plum was putin the bottle. This was allowed to remain forty- 
eight hours and then removed on the twenty-sixth; in it were 
found eight eggs, and two places eaten out, one nearly round, .18 
by .13 inch and .07 of an inch deep; the other .17 by .1 inch and 
OT deep. 
THe APHIDER. 
The wide spread distribution of the aphides, being found as 
they are on nearly every known tree and plant in the vegetable 
kingdom, with their many species, render them the most tenacious 
and at the same time destructive family of insects with which 
the horticulturist and orchardist has to deal. This is also pre- 
eminently true of the nurseryman, the suddenness of their 
appearance and the inconceivable rapidity with which they 
increase in number, make them a formidable enemy to him, cost- 
ing, in the aggregate, thousands of dollars annually for labor in 
applying remedies and in the dwarfing, and, in many instances, 
the total destruction of his stock. 
Nothing has yet been found which gives perfect satisfaction in 
destroying these pests, as many of the remedies cause almost as 
much damage as do the plant lice themselves.
