Our Insect Foes

Abstract

THE receipt of the eighth Annual Report on the noxious, beneficial, and other insects of the State of Missouri, and the conferences on insect destruction in connection with the Paris Insect Exhibition recently held, bring again prominently forward the question—what are we to do to cope with our insect foes? Mr. Riley, the State entomologist for Missouri, in his report, gives account of five noxious insects—the Colorado Potato-beetle (Doryphora Io-lineata, Say), the Canker Worms (Paleacrita vernata) and (Anisopleryx pometaria), the genus Paleacrita being a new one; the Army Worm (Leucania unipuncta, Han.), the Rocky Mountain Locust (Caloptenus spretus Tho.), and the Grape Phylloxera. In each case an account is given jofr the estimated amount of damage done, and the proposed methods for attacking the enemy, as well as the life history, so far as is known, of the insect itself. While the damage by Colorado Beetle during 1875 was less than usual, owing to the excessive wet drowning the bropds, and the Army Worm did comparatively little damage, the devastation caused by the locust was unusually heavy. Mr. Riley gives separately the accounts of different counties of the State.
