Abstract: The predation behavior of Eocanthecona furcellata on Agriophara rhombata larvae was studied, and the search and predation efficiency of different instars of Eocanthecona furcellata nymph on Agriophara rhombata larva was measured in the laboratory. The results showed that Eocanthecona furcellata nymphs searched for prey by swinging their antennae and used the retractable oral needle in their beak as the hunting and feeding tool. The predation effect of Eocanthecona furcellata nymphs was selective to Agriophara rhombata larvae, and the older nymphs had higher predation efficiency. Among them, the 5th instar of Eocanthecona furcellata nymphs had the highest predation efficiency on the 3rd instar of Agriophara rhombata larvae, which could search for the prey in about 5 minutes on average, successfully imbibe and start feeding in about 13 minutes, and it could suck dry one larva in 45 to 60 minutes; the density of the two species interfered with their predation ability.
