Abstract

Arthropod pests reduced overall yield by 7.66% in 1999. Acreage was up and yields were down, largely due to weather. Over 1 million acres of planted cotton were not harvested in 1999. Texas losses overshadowed those in the remainder of the cotton belt. Cotton fleahopper became the number one pest in 1999 at 2.36% reduction in yield. Boll weevil, no longer a major factor east of the Mississippi River, is still number two at 2.2% loss. The bollworm/budworm complex, causing 1.05% loss, was the number three arthropod pest of cotton in 1999. Sevently-nine percent (79%) of US cotton acres was infested by heliothines. Of those, 71% were bollworms, Heliocoverpa zea. Only 57% of US acreage is reported infested by boll weevils. Lygus at 0.93% loss was 4(th) and stink bugs (0.37%) were 5(th). Thrips (0.27%), aphids (0.22%), spider mites (0.12%), pink bollworm (0.037%) and silverleaf whitefly (0.02%) complete the the top ten insect pests of 1999. Total cost of management and loss to insects to the 1999 crop was $1.269 billion or $93.34 per acre. Of those costs approximately $50 are direct insect management costs.
