中文摘要:
【目的】为了明确不同寄主植物对亚洲玉米螟Ostrinia furnacalis (Guenée)生长发育、繁殖及雄蛾保护酶活性的影响。【方法】 在温度为(25±5)℃、湿度为75%±5%、光照周期为L∶D=16∶8 的恒定条件下,研究了7科12种寄主植物对亚洲玉米螟发育历期、蛹期、成虫期、羽化率、雌蛾繁殖力及雄蛾体内超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活力的影响。【结果】 亚洲玉米螟能够在12种寄主植物上完成生长发育。取食苍耳的幼虫历期较短(17.4 d),蛹期较短(5.9 d);成虫寿命较长(9.0 d),蛹重较大(50.7 mg);取食油菜的幼虫单雌产卵量较大(210粒/雌),取食油菜和油麦菜的幼虫成活率和蛹羽化率较高,均在80.0%以上。幼虫取食不同植物后,雄蛾体内保护酶的活性差异显著,幼虫取食酸模叶蓼后,雄蛾体内SOD活性较高,幼虫取食苍耳后,雄蛾体内POD和CAT活性较高。【结论】 不同寄主植物对亚洲玉米螟生长发育、繁殖及雄蛾保护酶活性均有显著影响。取食苍耳和酸模叶蓼有利于亚洲玉米螟的生长发育。玉米螟在不同寄主植物上的生长发育和繁殖与保护酶活性呈现正相关性。亚洲玉米螟在取食不同寄主植物时,能调节自身保护酶的活性,来适应寄主,满足生长发育的需要。
英文摘要:
[Objectives] To
understand the effects of different host plants on the growth, development, fecundity and protective enzyme activity, of Ostrinia furnacalis. [Methods] We studied the development, pupal stage,
adult stage, eclosion rate, female fecundity and superoxide
(SOD),peroxidase
(POD), and catalase (CAT) activity of male O. furnacalis raised on 12 host-plant species from 7 families under laboratory conditions; (25±5) ℃, 75%±5% RH, photoperiod=16 L︰8 D. [Results] O. furnacalis was able to complete growth and development on all 12 host plants. Larvae raised on Xanthium sibiricum had the shortest larval
and pupal stages, 17.4 d and 5.9 d, respectively, the longest adult life span
(9.0 d), and heaviest pupal weight (50.7 mg). The highest female fecundity,
210.1 eggs/female, was recorded on Brassica campestris. Larval survival and pupal eclosion rates on B. campestris and Lactuca sativa were all over 80.0%. There were significant
differences in the protective enzyme activity in males that had been raised on
different host-plants. Males raised on Polygonum capitatum had the
highest SOD, POD and CAT activity. [Conclusion] Different host plants had significant effects
on the growth, development, female fecundity and male protective enzyme
activity, of O. furnacalis. Feeding on Xanthium sibiricum and Polygonum lapathifolium was beneficial to the
growth and development of O. furnacalis. The growth, development and fecundity of O. furnacalis on different host plants
was positively correlated with protective enzyme activity. O. furnacalis can meet its growth and
development needs by adjusting its protective enzyme activity to specific
host-plants.
