Predation of boll weevils (Coleoptera: Curculionidae) by jumping spiders (Aranea: Salticidae)inhabiting grandlure baited pheromone traps was confirmed by using three genomic DNA based microsatellites developed in previous research. The jumping spiders interfere with the trap capture of boll weevils which are used to determine when eradication treatments are applied. The technique worked well and can be used for many other predation studies of the boll weevil
Species 1: Coleoptera Curculionidae Anthonomus grandis (Boll weevil)
Species 2: Aranea Salticidae (jumping spider)
Keywords: predation, genomic DNA
