查询词典 metamorphosis

METHODS: Feed the Bombyx siliworm larvae with artificial diet which added the 2,4-DCP and NP, then survey its weight, growth speed, metamorphosis, bionergy and fecundity in strict conditions.

RESULTS: The growth speed, weight, developmental uniformity, bionergy and fecuncity of the Bombyx silkworm descent dramatically as they eat the feed that the concentration of 2,4-DCP over 0.8 mmol L~-1 or NP exceed 0.500 mmol L~-1. But the effect on reproductive capacity vary with gender difference, it's more obvious on the late-stage of development and periods of metamorphosis such as ecolysis, pupation, edosion. There may be cumulative effect inside the Bombyx siliworm.

结果 家蚕幼虫食下含0.8 mmol·L~(-1)以上浓度的2，4-DCP或0.500 mmol·L~(-1)以上浓度的NP饲料，生长速度、生长量、发育整齐度、生命力和生殖能力都明显下降；生殖能力所受影响应性别而不同；家蚕发育后期和蜕皮、化蛹、羽化等变态时期影响更加明显，在蚕体内可能有累积作用。
