The first experiment examined how Lygus respond to gaps or field edges. All Lygus were collected from alfalfa and made into batches of ~300. Gaps in cotton rows were monitored for crossing flights. Lygus generally crawled onto plant before flying. Numbers of crossing Lygus were monitored each minute for 30 minutes. Percent crossing was analyzed as a function of gap distance, time of day, temp, wind speed and direction. Gap size was 0, 2 or 4 rows or a 10' berm into alfalfa. Percent crossing was significantly different among gap types with a flight increasing above a threshold temperature of about 90F. Another experiment measured the effect of crop type and cotton water and nitrogen fertilizer in on insects abundance. Each week in alfalfa, bean, and cotton, insects were swept. Cotton sampling was performed in each of 41 plots. Plant mapping and tissue samples were analyzed for N P K. Crop type and water treatment showed significant differences in several insects.
