Proactive classical biological control of Lycorma delicatula (Hemiptera: Fulgoridae) in California (U.S.): Host range testing of Anastatus orientalis (Hymenoptera: Eupelmidae)

Lycorma delicatula (Hemiptera: Fulgoridae), the spotted lanternfly, native to China, invaded and established in northeast U.S. 2014. Since this time, populations have grown spread rapidly, invasion bridgeheads been detected mid-western states (i.e., Indiana 2021). This invasive pest presents a significant threat Californian agriculture. Therefore, proactive classical biological control program using Anastatus orientalis (Hymenoptera: Eupelmidae), L. egg parasitoid was initiated anticipation of eventual establishment California. In support approach, potential host range A. investigated. Eggs 34 insect species either or non-native southwestern were assessed for suitability parasitism development . Of tested, 10, 13, one Hemiptera, Lepidoptera, Mantodea, respectively. species, eight Hemiptera two Lepidoptera evaluated. Host tests conducted quarantine facility, exposed individually mated females (Haplotype C) non-target target ) eggs sequential no-choice static choice experiments determine parasitization development. Additionally, sex ratio, fertility, size offspring obtained from Results testing indicated that is likely polyphagous can successfully parasitize develop belonging at least different orders Lepidoptera) seven families (Coreidae, Erebidae, Fulgoridae, Lasiocampidae, Pentatomidae, Saturniidae Sphingidae). Prospects use as agent are discussed.
