Abstract
Abstract Due to its role in the transmission of Candidatus Liberibacter asiaticus, a pathogen associated with huanglongbing, a catastrophic disease of citrus in the world, Diaphorina citri Kuwayama (Hemiptera: Liviidae) has become a very dangerous invasive pest. To contribute to increasing alternatives for its management, we evaluated against D. citri adults the pathogenicity of conidia and blastospores of 8 Mexican strains of the entomopathogenic fungus Hirsutella citriformis Speare (Hypocreales: Ophiocordycipitaceae). Furthermore, we conducted tests with non-target insects that included the predators Hippodamia convergens Guerin-Meneville (Coleoptera: Coccinellidae) and Chrysoperla rufilabris (Burmeister) (Neuroptera: Chrysopidae). Experiments in the laboratory included the application of the fungus by contact and through liquid sprays. Strains were collected from citrus areas of Mexico. They were grown in PDAY media and applied at 1 × 106 conidia per mL. All bioassays were conducted under controlled co...
