66 TRUCK CROP INSECTS. 
but, owing to lack of funds, it was impossible to make a complete 
survey. The beetles feed upon the foliage of various trees during 
the night time and hide in the soil during the day. They lay 
their eggs in the soil, particularly that which is in grass or similar 
crops and not well cultivated. Well-cultivated fields planted in 
crops such as potatoes or corn, probably had few eggs laid in 
them. The fields nearest to trees or woods would have more 
eggs than other fields out in the open. These eggs hatch into 
small white grubs during the summer and after passing the winter, 
they will be particularly abundant next year and destructive to 
such crops as corn, strawberries, potatoes; in fact, to most any 
crop planted in hills; and it also may prove very destructive to 
lawns. 
As it is impossible to successfully deal with the white grubs 
after they have started their injury, it is necessary for the farmer 
to plan his work and his planting in such a way as to avoid white 
grub injury. 
Notices have been sent out at several times during the summer 
to farmers, advising them of the approaching attack of white 
erubs. Some farmers have probably fall-plowed their land which 
is the first step for avoiding injury. All land which has been in 
sod, and particularly if it is near woods, is apt to be infested. If 
it is intended to plant crops in hills during the next summer in 
such fields, they should be fall-plowed. At the time of plowing, 
the farmer can readily determine if his fields are severely infested. 
Thirty to forty grubs turned over to each quarter-mile of furrow 
will mean a severely infested field next spring and hogs should 
be turned into such fields to root out the grubs. Such crops as 
are most susceptible to injury should be planted in fields not 
severely infested. Other crops, such as grain, buckwheat, clover, 
etc., should be planted on the infested land, as these suffer but 
little from the attack of white grub. Farmers throughout the 
State should plan their work now and carry it out next year, in 
such a way as to avoid injury from white grubs. 
If the farmer has failed to fall-plow grass land and, on plowing 
it in the spring, finds it infested with white grubs, he should not 
plant it in corn or other susceptible crop. In the case of lawns 
where it is impossible to plow, very little can be done. A recent 
bulletin from Michigan mentions a bacterial disease of white 
grubs which is considered to be rather wide-spread. If this is 
present in grubs in the lawn, it could be encouraged in its work
