Abstract

Liriomyza sativae Blanchard larval populations and damage were found to be somewhat snychronized to bell pepper growth stages. Populations remained low and fairly constant from seedling emergence to bloom. Damage during the cotyledon plant growth stage was considered important because of the few leaves and small amount of leaf area available for oviposition and mining activities. The rapid plant growth following the cotyledon stage was a major factor in limiting leaf-miner induced damage before plant bloom. Highest larval leafminer populations occurred from plant bloom through maturity and harvest with some corresponding increases in foliar damage.
