adaptable under the circumstances shall be used. It will be observed 
also that plans for evasion of losses from chinch bugs are presented 
in crop rotations and nonproduction of continuous-season host crops. 
Cooperation is absolutely necessary in order to obtain the fullest 
possible value from any method or combination of methods which 
may be used. 
First, there should be team work in surveying the neighborhood for 
possible pests. Growers should be continuously alert to discover the 
chinch bug, and other important crop pests as well, before such pests 
have begun their raids. Exceptional abundance, or even the mere 
presence of any unusual insect which may prove harmful, should be 
brought to the attention of their neighbors and the county agent or 
the nearest entomologist. Where possible this information should in- 
clude the name of the pest, its host plant, or its place of occurrence, 
and an estimate of its abundance. If it is plainly injuring a crop 
this fact should be stated. If its name is not known, specimens 
should be sent to the county agent or other authority, together with 
the name and address of the owner of the property where the sus- 
pected pest or the infestation occurs. 
Second, on discovering a threatened or actual outbreak a confer- 
ence of the farmers and the county agent in the threatened area, and, 
if possible, a State or Federal entomologist, should be held to plan 
the best possible campaign of control and to determine what equip- 
ment and chemicals are on hand or what must be purchased, either 
cooperatively or by individuals. There should be agreement upon 
the time to strike and the duties of each person concerned. Each 
man should definitely understand his duties, and agree to work 
simultaneously with his fellows so that their combined effort will 
either destroy a known center of infestation or at least place the pest 
under the most efficient control in that area or neighborhood. It is 
not enough merely to limit the direction of spread of the pest to a 
point away from the fields of the cooperating community. As an 
illustration, consider an extremely infested wheat field close to a 
county or State line. Cooperation is apt to be unusually difficult in 
such a neighborhood because two county organizations are involved. 
It is none the less vital, however, to have cooperation. To guard 
against the movement of the bugs to properties lying adjacent on 
one, two, or even three sides in the one county, and allow them to 
escape to property on the fourth side simply because that property 
is in another county, merely postpones and multiplies the trouble. 
Let us suppose the farmers in one county have cooperated with 
regard to purely defensive measures, causing bugs to migrate to 
adjacent fields in the adjoining county. The dispersion will furnish 
material for new infestations which will reinvade the territory
