REMEDIES. 



As the insect passes the winter in the soil, it is possible to destroy 

 some of them by late fall or early spring plowing, either burying them 

 so deeply that they never get out, or exposing them to their natural 

 enemies. This practice should be carried on over a wide area, however, 

 if much benefit is to be received, for the adults can fly with ease from 

 one farm to another. 



Fall Army-worm {Laphygma frugiperda) . 



A close relative of the army-worm, but one sometimes exhibiting quite 

 different habits, is the fall army-worm. The larva of this pest is about 

 one and one-half inches long, striped longitudinally, with numerous 

 raised, black points, from each of which springs a black hair. The head 

 is marked with a V-shaped mark. There are several generations each 

 3'ear, the last one doing the most injury. Unlike the regular army- 

 worm, this insect does not move in well organized bodies, but each larva 

 migrates in its own way. In the northern part of this, State,. the writer 

 has seen these caterpillars working in the ears of corn, very much as 

 do the larvae of the boll-worm or corn-ear worm. One or more cater- 

 Ijillars tunnel in the green kernels while it is "in the milk." Here they 

 render the sweet-corn unfit for market by eating out a portion of the 

 kernels and soiling the rest in the vicinity of their tunnels. 



REMEDIES. 



Fall plowing is the only really sensible remedy. The greater part 

 of these pests that live over winter, do so in the larval stage in the 

 soil, and fall plowing destroys many of them while they are in their 

 earthen cells.

Bumble Flower-beetle {Euphoria inda). 



This is a thick-set, awkward beetle of dull-yellow and brown color. 

 It resembles somewhat the June-beetle in its habits, but unlike that 

 well known insect this beetle does all its injury to crops in the adult 

 condition. It attacks fruits and corn in September and October, making 

 its way into the ears of corn, and feeding on the soft, pulpy kernels 

 when they are in the milk. A few years ago, before evaporators came 

 into use, and when it was customary to dry corn in the sun, this beetle
