Temporal distribution of Froggatt’s apple leafhopper (Typhlocyba froggatti Baker) and the parasite Anagrus armatus (Ashmead) in an abandoned orchard

Abstract

Three life stages (summer eggs, nymphs, and adults) of Froggatt’s apple leafhopper (Typhlocyba froggatti Baker) were sampled in an abandoned Canterbury apple orchard over two seasons. Leaf samples for summer eggs and nymphs, and sticky board samples for adults, strongly indicated the presence of two generations and the possibility of a partial third. Summer eggs of T. froggatti were parasitised by immature stages of Anagrus armatus Ashmead. Sticky board samples of A. armatus adults indicated good temporal synchronisation between the parasite and host populations.
