Notes on some insects intercepted entering New Zealand in 1975.
Of the 2359 examples of insects intercepted in 1975 by the Port Agricultural Service in New Zealand and identified at Levin, those belonging to 5 species are discussed in this paper, not only because of their potential significance as plant pests, but because they illustrate the risk of plant pests arriving in non-host material. They include Hypera postica (Gyth.) (variabilis (Hbst.)), a pest of legumes, especially lucerne, examples of which were found in a shipment of pomegranates from the USA; Sitona lineatus (L.), a pest of legumes, found on carnation cuttings from Holland; S. humeralis Steph., a pest of legumes that has already become established in parts of New Zealand, which was found in several consignments of oranges from Australia; and Leptocneria reducta (Wlk.), the larvae of which feed on the ornamental white cedar (Melia azedarach), in a crate of household goods from Australia.
