Studies on Prevention of Resistance in Cryptolestes Ferrugineus

摘要

In this study we have compared the efficacy of different fumigation methods for control of Cryptolestes ferrugineus in maize, wheat and paddy, including: the recirculation fumigation with DDVP（by surface application) and AlP（application to surface and at intake), recireulation fumigation under film with DDVP（by intake) and AlP（application at intake and under the surface with small clothbag). The experimental results indicate that the last method can control cryptolestes ferrugineus effectively in imported wheat and prevent other insect pests at the same time.
