Preliminary observations on <i>Zelus obscuridorsis</i> (Stål) (Hemiptera: Reduviidae) as predator of the corn leafhopper (Hemiptera: Cicadellidae) in Argentina

The corn leafhopper <i>Dalbulus maidis</i> (Hemiptera: Cicadellidae), is an important corn pest in most of tropical and subtropical America. This leafhopper has a rich natural enemy complex of which parasitoids and pathogens are the most studied; knowledge on its predators is limited. We...

description The corn leafhopper <i>Dalbulus maidis</i> (Hemiptera: Cicadellidae), is an important corn pest in most of tropical and subtropical America. This leafhopper has a rich natural enemy complex of which parasitoids and pathogens are the most studied; knowledge on its predators is limited. We noted the presence of the native assassin bug <i>Zelus obscuridorsis</i> (Hemiptera: Reduviidae) predating diverse motile insects, including the corn leafhopper, on corn plants cultivated in household vegetable gardens in San Miguel de Tucumán (Argentina); in order to verify its predatory actions, we exposed lab-bred individuals of <i>D. maidis</i> to adults of <i>Z. obscuridorsis</i>. The predators were starved for 24 h before trials in which the corn leafhopper in different developmental stages were exposed. <i>Zelus obscuridorsis</i> is highly skilled in catching specimens in motion, but it was not able to prey on eggs. The predator was capable to catch and prey on nymphs and adults.
