Book Description
Excerpt from Aerial Dispersal of the Pink Bollworm in the United States and Mexico: Production Research Report No. 96 Light traps have been used to detect the occur rence and dispersal of pink bollworm moths in many areas. Glick and Hollingsworth who operated traps in the lower Rio Grande Valley during the summer and fall of 1952, collected many pink bollworm moths; they trapped more moths in late August than in any other month. During one night (august immediately after cotton stalks in the area had all been destroyed, they collected an estimated pink bollworm moths. The following ni ht, the collected only and 8 days later Septem r 6) only 34. They concluded that because the cotton stalks had been completely destroyed, the moths had taken flight to another area more promising. Since at this time the prevailing wind was south southeast, they probably dispersed in a northerly direction. During the late summer of 1952, Glick and Hollingsworth (8) collected pink bollworm moths from light traps placed in the northeastern part of Texas; before this time the area had not been known to be infested. Their finding indicated that moths had migrated into the area. The moths were probably carried by the southerly winds from a heavy infestation on late cotton in the Corpus Christi area that was present in the fall of 1951.

Pink Bollworm Control in the Western United States (Classic Reprint)

Book Description
Excerpt from Pink Bollworm Control in the Western United States Avoidance of early planting can reduce the numbers of moths that survive to infest cotton in the spring. If planting is too late, however, it can result in yield losses, increased damage by late season infestations of insects such as the tobacco budworm, and increased proportions of the pink bollworm and other pests entering the overwintering stage. The most practical approach to reducing pink bollworm populations is to plant when optimal conditions for seed germination occur, produce a heavy boll set before the extreme summer heat reduces fruiting, and terminate fruiting earlier than it is now normally accomplished. At present, early termination of fruiting is limited to cessation of irrigation and to early maturing varieties. An irrigation termination of August 1 at Yuma, Ariz., reduced overwintering pink bollworm populations with no reduction in yield compared with later irrigation termination dates. This date would have to be altered for other locations, depending on soil type and other factors. Not only does the production of an early cotton crop decrease overwintering pink bollworm populations, it also may result in increased quality of the cotton by avoiding insect damage, boll rot, and storm damage that can occur in later cotton. Plant growth regulators have been used effectively to terminate cotton fruiting. These may have some advantages over irrigation termination, but none is registered for this use on cotton as yet.

A Maggot Trap in Practical Use

Book Description
Excerpt from A Maggot Trap in Practical Use: An Experiment in House-Fly Control It is the writer's intention here merely to point out that the disposal of manure on the platform maggot trap is but a slight modification of the method just mentioned. Figure 4 differs from a diagram given by Ringelmann only in the platform and in the outlets through which the drowned larvae may be washed into the cistern. Here is shown the cistern in which the liquid manure collects. Watering with the liquid manure adds to the heap the valuable Constituents of the urine and promotes the anaerobic fermentation. If it is true, as just suggested, that lack of oxygen and the presence of carbon dioxid render the manure unfavorable for the development of the larvae, it follows that compact heaping and watering, by excluding air and increasing the moisture content, also insure the greatest percentage of migration. As a matter of fact, compactness and high moisture content are the very factors which make the maggot trap mest effective, whether the explanation is to be found in the temperature, or moisture, or lack of oxygen.
