The egg parasitpoids Trichogrammadanausicida (Nagaraja) and Trichogrammacacaeciae (Marchal) (Hymenoptera: Trichogrammatidae), are reported for the first time in Israel. Moreover, our discovery of T.danausicida is the first report of this parasitoid species outside of India. The occurrence of those trichogrammatids was first discovered and documented in May 2016 during a survey of egg parasitoids of the False codling moth Thaumatotibialeucotreta (Lepidoptera: Tortricidae). The field survey was conducted on castor bean fruits (Ricinuscommunis) in the Israeli central coastal plain. The identity of the parasitoids was revealed by means of sequencing a portion of the cytochrome oxidase I gene (COI) of the studied parasitoids.

Abstract The false codling moth Thaumatotibia leucotreta (Meyrick), is an invasive species in Israel. In order to carry out a classical biological control program, the African egg parasitoid Trichogrammatoidea cryptophlebiae (Nagaraja) was recently introduced into Israel, and nontarget host risk assessment was performed as required. In no-choice tests we determined that T. cryptophlebiae was unable to develop in eggs of four nontarget Lepidopteran species: Pectinophora gossypiella (Saunders), Spodoptora littoralis (Boisduval), Ephestia kuehniella (Zeller), and Belenois aurota (Fabricius). Conversely, it developed in three Lepidopteran species eggs of the Tortricidae family: Cydia pomonella (Linnaeus), Lobesia botrana (Denis and Schiffermüller), and Epiblema strenuana (Walker). Epiblema strenuana eggs showed the lowest parasitism level among all tested moth eggs of the Tortricidae family. The progeny production of parasitized false codling moth eggs was similar to that of C. pomonella eggs, but smaller than that of L. botrana eggs. However, moth egg and parasitoid clutch sizes were smallest on L. botrana eggs and largest on C. pomonella eggs. In choice bioassays, T. cryptophlebiae significantly preferred to parasitize T. leucotreta eggs over the eggs of C. pomonella, L. botrana, and E. strenuana. Moreover, the choice of T. leucotreta eggs over the eggs of L. botrana was not affected by the parasitoids’ rearing histories. Our data support the assumption that T. cryptophlebiae develops only in moth species of the Tortricidae family. Thus, the risk that it may attack nontarget species is low.
