Table Of Insect Pests

The following tabulated statement of the various insect pests may be of use to the cultivator. Special stress is laid upon the Period of Rest (chrysalis stage) column. That is when the soil should be kept stirred up with the hoe, even if it cannot be dug with the spade or the fork. It is of course understood that one of the objects in stirring the soil is to enable the birds to get at the grubs. The column indicating Period of Destruction (the larval stage), is useful as indicating the period when the various washes and sprays are likely to be most effectual.
