Short season cotton varieties promise to escape damage from the boll weevil. In 

 addition, by maturing early - before the environment forces the boll weevil and 

 pink bollw)rra into diapause - these cottons provide an "automatic" mechanism for 

 reducing the nvunbers of these pests that are able to successfully prepare for 

 the winter season. This is simply because these varieties may be harvested and 

 plowed under so early that there should be no bolls or squares available for the 

 development of diapausing individuals. The continued growing of the new cotton 

 types over large geogtaphic areas, combined with a regulated date for stalk 

 destruction, promises to relegate the boll weevil end pink bollwjrn in Texas to 

 the status of minor pests. In addition to the program in cotton breeding, state 

 and federal entomologists in Texas also are seeking better methods for using 

 insect pathogens, pheromones, selective insecticides, and modified cropping 

 systems to maintain pest populations below damaging levels. The new system that 

 will emerge will integrate pest population suppression practices in a compatible 

 manner in order to optimize yields and producer profits. This should be the 

 ultimate goal of any crop production program.

Insecticidal control of fall populations of boll weevils in the High and Rolling 

 Plains during 1964 and 1965 made it possible to compare the relative 

 effectiveness of two types of diapause control programs. Both programs dealt 

 with reducing the overwintering boll weevil population. The 1964 program 

 utilized six applications of malathion in an attempt to kill the potential 

 overwintering adults during the feeding period after they had emerged from 

 infested squares or bolls but before they had left the cotton fields for nearby
