fruit; the larva is also the well-known grub or “ worm 99 
of “ wormy ” cherries. The presence of this insect in an 
orchard can be determined early in the season by a peculiar 
mark it makes when laying its eggs in the young fruit. The 
female beetle makes an incision, with her snout, through 
the skin of the fruit. In this incision she lays a single egg, 
which she pushes with her snout to the bottom of the cav¬ 
ity that she has prepared. She then makes a crescent¬ 
shaped incision in front of the one containing the egg. This 
last cut undermines the egg, leaving it in a little flap. The 
larvse feed within the fruit. In the case of plums the in¬ 
fested fruit falls to the ground; but not so with cherries. 
When full grown the larvae usually go into the ground to 
transform; a few transform within the fruit. This species 
infests nectarines, apricots, and peaches as well as plums 
and cherries. This insect is fought in two ways: the 
beetles are jarred from the trees upon sheets in early spring, 
and destroyed before they have laid their eggs; they are 
also poisoned by spraying the trees with Paris-green-water 
before the fruit is large enough for them to oviposit in it 
The adult beetle feeds upon the foliage, and can thus be 
poisoned. 
As yet this species does not occur on the Pacific coast, 
and the greatest care should be taken that it be not intro¬ 
duced there. 
The Apple-weevil, Anthonomus quadrigibbus (An-thon'o- 
musquad-ri-gib'bus), infests the fruit of apple. The specific 
name was suggested by the fact that there are two wart-like 
projections near the hinder end of each wing-cover. 
The Strawberry-weevil, Anthonomus signatus (A. sig- 
na'tus), is sometimes a serious pest in strawberry 
plantations. The adult beetle (Fig. 725) punctures

ouds, and lays her eggs within the buds. The buds drop to 
the ground, and the larvae, one in each, develop within them.
