Recent aspects of stored product entomology in New Zealand

Abstract

Abstract Stored-product insect problems in New Zealand since 1970, and interceptions at quarantine since 1955 of potentially important species, are reviewed. Reesa vespulae (Milliron) and Sphaericus gibboides Boieldieu have recently been reported from New Zealand for the first time. Quarantine interceptions of potentially important species include Bruchus pisorum (L.), Trogoderma granarium Everts, T. variabile Ballion, and Anthrenus flavipes LeConte. During the 1970s insect (and mite) contamination of dried milk products occurred after long periods of storage. In North Island poultry houses mature larvae of Dermestes maculatus de Geer damaged structural timbers, and Alphitobius diaperinus Panzer occurred frequently and sometimes damaged polystyrene insulation. Hofmannophila pseudospretella (Stainton) larvae attacked carpets (many less than 6 years old), and after news media publicity 250 complaints of moth attack (72% due to H. pseudospretella) were reported to the New Zealand Wool Board from 8 November 1...
