58 FIRST ANNUAL REPORT OF THE STATE ENTOMOLOGIST. 



' Gathering and destroying fallen infested fruit: for the apple-worm 

 {Carpocapsa jjomoiiella), and the plum curculio. 



Probing burrows and killing the grubs with a bent wire or flexible 

 stick: for the round-headed apple-tree borer [Saperda Candida), 



Cutting out the larvas from tree-trunks: for the flat-headed apple- 

 tree borer [Chrisobothris femorata), and the peach-tree borer. 



Digging about plants for cut-worms destroying young cabbages 

 (larvae of Hadena devastatrix and H. subjuncta), tomatoes (the greasy 

 cut-worm, Agrotis ypsilon), and other plants (various species of 

 Agrutis, Mamestra and Hadena. 



Searching with a lantern for night-feeding caterpillars upon grape 

 vines (for Agrotis cupida*), and upon apple, pear, peach, and cherry 

 trees, for the climbing cut-worm {Agrotis scandens), the dark-sided 

 cut-worm [Agrotis Cochrani), and others. A sudden jar upon the tree 

 will cause many to drop to the ground when they may be readily 

 noticed and killed. 



Attracting to fires of dry wood where it is abundant, or of refuse 

 material from the tields, insects abounding at certain seasons, and known 

 to be readily attracted by light. 



Attracting to lamps placed in a vessel of oil or adhesive mixture ; as 

 has been done for destroying the cotton-worm moth (Aleiia argillacea).\ 



Attracting to poisoned sweets, as molasses and beer (the bait used 

 by collectors in "sugaring" for moths for their cabinets), in which a 

 small quantity of arsenic or cyanide of potassium has been mixed, to 

 be spread on trees, fences, or leaves of plants. 



Burning the dead stalks, leaves and other garden refuse in the late 

 autumn to destroy hibernating insects. 



Burning stubble in the autumn to destroy the pupse of the Hessian fly 

 [Cecidomyia destructor), unless they are found to contain parasites, 

 when burning would do more harm than good. 



Deep plowing in the autumn, to crush or bury delicate pupae that lie 

 near the surface. 



Ditching to collect "marching" caterpillars, as of the army-worm 

 (Leucania tmi^mncta) , and in the Western States the chinch-bug 

 [Blissus lencopterus). 



Barricading with boards coated with coal-tar to prevent migration 

 from one field to another. 



Pouring tar upon the ground along the exposed sides of fields to 

 serve instead of boards to arrest migration,

•Hn Bulletin No. 3 of the U. S. Entomolog. Commis., on the Cotton-worm, are given 

 notices of ten different lamps, of which some are movable on wheels for drawing through 

 the fields, with illustrations of several of them.
