初步试验结果表明:小麦吸浆虫以21℃和土壤含水量20%处理组合化蛹率最高,23℃和土壤含水量25%的处理组合最低。在各组合处理中,都有一部份不化蛹羽化的滞育幼虫。在室内自然变温下,蛹的发育历期,19.9℃为10.94天,21℃为10.63天,22.4℃为8.47天,蛹的发育始点(C)为14.6℃,有效积温常数(K)为66.6(日度)。在恒温下C=13.9℃,K=62.9(日度)。
The results of the preliminary experiment showed that the combination pupae rate was the highest at the treatment of 21 ℃ and soil moisture 20%, and the treatment combination of 23 ℃ and 25% soil water content was the lowest. In each combination treatment, there is a part of the diapause larvae that are not pupal eclosion. Under natural indoor temperature, the developmental duration of pupae was 10.94 days at 19.9 ℃, 10.63 days at 21 ℃, 8.47 days at 22.4 ℃, 14.6 ℃ and effective accumulated temperature constant (K) of 66.6 (K) Day). C = 13.9 ° C at constant temperature, K = 62.9 (day).
