中文摘要:
      为明确西花蓟马Frankliniella occidentalis消化酶对不同食物短期适应的调控作用。用玫瑰花瓣、玫瑰花朵(含花粉花蜜)和10%蜂蜜水+菜豆豆荚3种食物分别饲养西花蓟马成虫,测定西花蓟马在取食1、3、6、9、12、24和48 h时其成虫体内α-淀粉酶、胰蛋白酶和胰凝乳蛋白酶活性的变化。结果表明,成虫体内α-淀粉酶和胰蛋白酶在任何时间下均是取食玫瑰花朵的活性最高,大多数时间下玫瑰花瓣的最低。随着西花蓟马取食时间延长,除取食玫瑰花瓣的虫体α-淀粉酶是先降低后升高外,取食另外2种食物的α-淀粉酶和胰蛋白酶活性均是先升高后降低。西花蓟马体内胰凝乳蛋白酶活性的变化在取食3-6 h是取食玫瑰花朵的活性最低,在其余时间下酶活性在三种食物间没有明显的规律。结果说明西花蓟马可通过快速调节体内消化酶活性来适应不同食物的变化,达到自身生长发育对营养物质的需求。
英文摘要:
      In order to clarify the feeding metabolism mechanism of Frankliniella occidentalis in short-term adaptation to different foods, three foods of rose petal, rose flower (containing pollen and nectar) and 10% honey solution+kidney bean pod were used to feed F. occidentalis. The differences in the activities of digestive enzymes (α-amylase, trypsin and chymotrypsin) were compared after feeding the various foods at 1 3, 6, 9, 12, 24 and 48 h, respectively. The results showed that the α-amylase and trypsin had the highest activity in feeding rose flower at any time, and was the lowest in rose petal at most time. The activity of α-amylase in the rose petal firstly decreased and then increased, while it firstly rose to the highest level and then dropped to the lowest with time extension. The activities of chymotrypsin were lowest when fed rose flower at 3 and 6 h, and which hadn’t obvious regularity at other time. The results of the study indicated that F. occidentalis could rapidly adjust the activities of digestive enzyme, to adapt different foods and achieve sufficient nutrients for growth and development.
