Cold storage as a quarantine treatment to prevent the introduction of Spodoptera littoralis (Boisd.) into glasshouses in the U.K.
In laboratory tests, eggs and young larvae of Spodoptera littoralis were exposed to cold treatments of varying temperature and duration in an attempt to find an alternative to the current quarantine treatment of 10 days' storage at 1-2 degrees C, which damages some imported chrysanthemum cuttings. The alternative cold regimes tested, i.e., 1 degree C for four to eight days, 3 degrees C for seven days, 4 degrees C for four to six, eight and ten days, and 7 degrees C for seven days, did not eradicate S. littoralis. Differences in response to cold were observed both between strains and within developmental stages of S. littoralis
