Economic entomology for the farmer Economic entomology for the farmer and the fruit grower, and for use as a text-book in agricultural schools and colleges; economicentomolo00smit Year: 1906 396 AN ECONOMIC ENTOMOLOGY. The ploug-hing should be deep and as thoroughly done as pos- sible, so as to not only disturb and break up the nests com- pletely, Init to scatter the plant-lice, eg'gs, or other material that the ants may have gathered. By this simple means injury may frequently be prevented during the year following. Incidentally it has been mentioned that some species of ants gather honey and store it ; and, curiously enough, instead of building cells for its reception, as do the bees, a special form of Fig. 451. Honey-ants, Myrmecocystus tnelliger, filled with honey. worker is developed, with an unusually elastic crop and abdo- men. These specimens are simply stuffed by the other workers until they become of the size of a small cherry, utterly helpless and incapable of motion. In this condition they cling to the walls of the nest until, in the course of time, their stock is used up, when they again resume activity. Three of the other ant families to which reference has been made contain no species of particular interest to the farmer, how- ever interesting they may be to the student. But in the family MyrmicidcB we again find species that are numerous and of more or less importance to man. Here the petiole of the abdomen is two-jointed, differing thus from the other important family, Formicidce. Many of the species have the sting well developed in workers and 'queens,' and are for- midable creatures by reason of this weapon ; but not all our forms are so furnished, as is known by those who have suffered from an invasion of small red ants in houses. This little creature, Mono- morhini pharaonis, sometimes occurs in myriads, and nothing is
