Technical Abstract: Pecan and peach orchards may offer a suitable environment for using entomopathogenic nematodes to control key insect pests such as pecan weevil (Curculio caryae), plum curculio (Conotrachelus nenuphar), peachtree borer (Synanthedon exitiosa), and lesser peachtree borer (Synanthedon pictipes). For example, high levels of field suppression have been observed for larvae of plum curculio (>90% control), and peachtree borer (87% control), whereas field suppression of adult pecan weevil has been variable (50-80% control). Depending on the target insect and commodity, key barriers for adopting entomopathogenic nematode technology within grower systems include economics and competitiveness with other control strategies, efficacy, and environmental persistence. Nematode strain improvement and improved application or formulation methods may enhance efficacy. Hybridized strains have shown improved efficacy for pecan weevil in the laboratory and are being incorporated into field studies. Application of nematode infected-hosts for peachtree borer, and formulations that prevent rapid desiccation for lesser peachtree borer may improve control of these pests.
