Abstract
Experiments with six hemipterous insects belonging to the family Miridae (Psallus seriatus, Lygus pratensis, Adelphocoris rapidus, Creontiades debilis, Poeciloscytus basalis, and Lygus apicalis proved that each species when allowed to feed on cotton plants caused the young squares to shed or become blasted, produced lesions along the main stem, branch stems, and leaf petioles, and caused mutilations of leaves.
