【Abstract】 Anteon jurineanum Latreille,parasitizing Macropsis matsudanis,M.virescens,Empoasca flavescens in Shanghe of Shandong Province and M.cannabis in Nanjing,had both the predation and parasitic capacity.Its larval morphology,life history and habits were first described.Anteon jurineanum had one generation a year in Shanghe.It overwintered and oversummered as matured larva in the 4th instar in cocoon on the ground.The adult emerged in the last ten days of April the next year and preyed on the nymphs of the host for nutrition.It laid eggs in thoracic part in the base of midlegs and hindlegs of Macropsis matsudanis nymphs between the 3rd and 5th instars.The average egg stage lasted 72.8 hours,the average duration between hatching and excystation of the larva was 149 hours and average pupal stage was 16.1 d.The parasitization on Macropsis matsudanis was 24.3%～60.3%.更多还原
