Monitoring Oobius agrili Zhang and Huang (Hymenoptera: Encyrtidae), an egg parasitoid being released for biological control of emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is challenging due to its small size the cryptic placement host eggs. We compared four O. recovery methods: 1) rearing adults from bark (bark rearing); 2) sifting parasitized eggs sifting)...
