TI - Increased insecticide use in cotton may cause secondary pest outbreaks JF - California Agriculture JO - Calif Agr Y1 - 1976/08/01 VL - 30 IS - 8 SP - 14 EP - 15 PB - University of California Agriculture and Nature Resources SN - 0008-0845 UR - http://www.ucanr.edu/sites/calagjournal/archive/?article=ca.v030n08p14 AB - Pink bollworm, Pectinophora gossy-piella (Saunders), invaded southern California's lower desert valleys during the 1966 cotton growing season. Because of the widespread, damaging infestation levels, multiple applications of broad-spectrum insecticides have been used to reduce losses. These insecticides have proved extremely toxic to beneficial insect populations and are suspected of inducing outbreaks of other cotton pests.
