Abstract
Removal of extrafloral nectaries from cotton plants reduced populations of the cotton fleahopper, Pseudatomoscelis seriatus (Reuter) and the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) ca. 60% Total populations of natural enemies were also reduced by the nectariless plant; reductions ranged from 17–35%. Significant effects were found with Chrysopa carnea Steuens (4 locations), Orius insidiosus (Say) (2 locations), Coleomegilla maculata (De Geer) (one location), Hippodamia convergens Guérin-Méneville (2 locations), Spanagonicus albofasciatus (Reuter) (one location), Nabis spp. (one location) and a tachinid fly (one location). Laboratory experiments with tarnished plant bugs indicate a 92% reduction in oviposition on nectariless cotton plants.This publication has 0 references indexed in Scilit:
