hibit wide acceptance and usage of a trap-crop system by Individual growers. 

 Hopefull;/, additional research may produce methods of trap cropping that will 

 negate the necessity of early planting. For example, it may be possible to 

 create a crap crop in a regularly planted portion of a field by the efficient 

 use of grandlure bait stations alone. These baited portions could be treated 

 with systemic or foliar-applied insecticides to kill weevils attracted by 

 the grandlure.

In summary, the aldicarb-treated, early planted trap crop system was very 

 effective in attracting and concentrating early-season boll weevil and boll- 

 worm populations in cotton. Damaging infestations of these pests were not 

 sustained in the regular crop throughout the test period. Although further 

 research is needed to clarify the role of each o f the insect suppression 

 factors involved in the experiment, and while improvements must be made 

 in mid-season suppression of Heliothis , it seems obvious from these 

 studies that the pest management system tested has great potential for 

 cotton insect pest suppression.

It is apparent from these data that trap crops were an effective means of 

 concentrating and suppressing emerging boll weevil populations if the trap 

 crops were planted earlier than the main crop, and if pheromone bait stations 

 were used.
