Department of Entomology
The work of the department for the last year has been of two kinds. First, the attempt to keep in check the injurious insects of the farm, garden, and tree plantations. Second, such experiments and original investigations as could be made. The progress of events showed early in the season that cut-worms were among our worst enemies, and later reports as given further on, show them to be quite generally distributed through the State. They have, therefore, received as much attention as circumstances would allow. Notes more or less extended were made on various other pests in their season but this group has been selected as our chief subject of study. To speak of the "cut-worm" in a general way may be intelligible enough to most people, but still it should be remembered that there are many species. Probably as many as twenty-five are found in our State, though about half a dozen species compromise a majority of the worms. While there is a general similarity of habits among these common species, it may yet be found that the differences which exist are sufficient to require widely different methods in the extermination of the worms.
