The Turnip Aphid in the Southern States and Methods for Its Control
"The turnip aphid is one of the most destructive and widely distributed pests of turnip, mustard, radish, and related crops in the United States. It causes heavy losses to growers of these crops every year, especially in the Southern States. Dust mixtures containing derris, cube, or nicotine, and sprays containing derris or cube, will control the turnip aphid when applied properly. The first application of insecticides should be made when the plants are very small, and additional applications should be made at intervals of 7 to 14 days up to the time of harvest. To provide for effective application of insecticides, the seed of susceptible crops should be planted in drills, with the rows spaced uniformly apart. The following cultural practices aid in the successful production of crops exposed to turnip aphid attack: (1) A well-prepared, fertile seedbed to produce thrifty and rapidly growing plants, (2) planting the seed in drills to permit cultivation, (3) harvesting early to shorten the period of exposure to infestation, (4) destroying crop remnants to eliminate a common sources of infestation to succeeding crops, and (5) applying a nitrogenous fertilizer to stimulate plant growth." -- p. ii

"Cotton bollworm, corn earworm, tomato fruitworm, and false budworm of tobacco are common names applied to one and the same insect when it is found attacking these various crops. In fact the insect is a very general feeder, attacking many wild plants as well as garden vegetables, alfalfa, cowpeas, and the crops indicated above. The bollworm, or corn earworm as it is most widely known, occurs as a pest in practically all parts of the United States." -- p. 3.

Feasibility of Using Remote-Sensing Techniques for Shoreline Delineation and Coastal Habitat Classification for Environmental Sensitivity Index (ESI) Mapping
Environmental Sensitivity Index (ESI) provides shoreline classification and a sensitivity ranking that is important for oil spill planning. This system has not been used in Louisiana due to the rapid changes of the shoreline, which is a potential threat due to high risk of oil spill in that region. This research paper's goal is to develop remote sensing classification procedures to create an ESI map for Louisiana and other areas that present similar issues.
