摘要
在 2 0 - 32 .5℃范围内 ,烟草甲卵期、幼虫期、蛹期、成虫产卵前期及全世代的发育速率与温度呈逻辑斯蒂曲线关系 ,但高温 ( 35℃以上 )对烟草甲的生长发育有明显的抑制作用。烟草甲各虫态的发育起点温度和有效积温分别为卵 :15.4 866℃ ,35.9892日度 ;幼虫 :10 .3553℃ ,4 2 2 .0 4 62日度 ;蛹 :15.4 2 39℃ ,72 .380 8日度 ;产卵前期 :14.70 0 7℃ ,2 0 .84 2 7日度 ;全世代 :12 .52 4 6℃ ,52 4 .84 95日度。
The relationship between temperature and the development of egg, larva, pupa, preoviposition, and the whole generation of Lasioderma serricorne (Fabricius) shows Logistic model from 20 to 32.5 ℃. However, higher temperature (above 35 ℃) will restrain their development. The development zero and effective accumulative temperature are as follows: 15.4866 ℃ and 35.9892 DD for egg, 10.3553 ℃ and 422.0462 DD for larva, 15.4239 ℃ and 72.3808 DD for pupa, 14.7007 ℃ and 20.8427 DD for preoviposition, and 12.5246 ℃ and 524.8495 DD for the whole generation, respectively.
