摘要: 为探索利用植物资源防治靶标害虫,选用农田常见杂草地黄处理棉田主要害虫棉铃虫,利用饲料与地黄根或叶干粉混拌法,调查棉铃虫发育历期、死亡率和虫重,研究对其影响。结果表明:随着饲料中地黄根或叶粉末含量的升高,棉铃虫的死亡率升高、发育历期延长、虫重减轻。取食地黄根混拌饲料的棉铃虫2龄、3龄、4龄、5龄和6龄幼虫的死亡率,分别比对照组升高3.25%~5.82%、22.92%~35.42%、4.10%~9.69%、41.22%~65.58%和12.65%~67.67%;1龄、2龄、3龄、4龄和5龄的棉铃虫幼虫发育历期分别比对照延缓0.00~2.50、1.00~2.25、1.00~6.25、0.00~1.75、0.50~1.50 d,幼虫发育至6龄时,生长发育缓慢且无法正常完成生活史;3龄、4龄、5龄和6龄棉铃虫幼虫虫重分别比对照降低43.79~130.18、152.56~255.47、127.27~327.91和41.75~177.22 mg。另外,取食地黄叶混拌饲料的棉铃虫1龄、2龄、3龄、4龄、5龄和6龄幼虫的死亡率,分别比对照组升高5.75%~11.46%、3.09%~11.67%、42.71%~66.27%、16.29%~83.33%、21.67%~100.00%和5.17%~42.67%;1龄、2龄、3龄、4龄和5龄的棉铃虫幼虫发育历期分别比对照延缓1.00~2.00、0.00~4.00、0.00~4.00、0.00~0.50和1.50~4.00 d,6龄幼虫无法正常完成生活史;3龄、4龄、5龄和6龄棉铃虫幼虫虫重分别比对照降低47.11~134.18、170.76~259.19、141.51~317.33和78.24~334.93 mg。通过研究地黄对棉铃虫生长发育、死亡率和虫重的影响,结果表明其对棉铃虫有一定的抑制作用,可为有效利用农田杂草资源开发植物源杀虫剂奠定理论基础。

Abstract: In order to explore the use of plant resources to control target pests, this paper selected the common weed Rehmannia glutinosa to treat cotton bollworm, the main pest in cotton field, used feed, R. glutinosa root and leaf dry powder mixing method and preparation of plant extract, investigated the development period, mortality and insect weight of cotton bollworm, and studied the influence on them. The results showed that with the increase of Rehmanniae root and leaf powder content in diets, the mortality and development period increased but the weight of cotton bollworm decreased. Compared with the control group, the mortality of the 2nd, 3rd, 4th, 5th and 6th instar larvae was increased by 3.25%-5.82%, 22.92%-35.42%, 4.10%-9.69%, 41.22%-65.58% and 12.65%-67.67%, respectively. The larval development period of the 1st, 2nd, 3rd, 4th and 5th instars of cotton bollworm was delayed by 0.00-2.50, 1.00-2.25, 1.00-6.25, 0.00-1.75, 0.50-1.50 d, respectively. When the larval development reached the 6th instar, there was slow growth and inability to complete life cycle; the larva weight of the 3rd, 4th, 5th and 6th instars was 43.79-130.18, 152.56-255.47, 127.27-327.91 and 41.75-177.22 mg lower than that of the control, respectively. In addition, compared with the control group, the mortality of the 1st, 2nd, 3rd, 4th, 5th and 6th instars of Helicoverpa armigera larvae fed with the mixed feed of R. glutinosa leaves increased by 5.75%-11.46%, 3.09%-11.67%, 42.71%-66.27%, 16.29%-83.33%, 21.67%-100.0% and 5.17%-42.67%, respectively; the larval development of the 1st, 2nd, 3rd, 4th and 5th instars was 1.00-2.00, 0.00-4.00, 0.00-4.00, 0.00-0.50 and 1.50-4.00 d, respectively, and the 6th instar larvae could not complete the life cycle normally. The larval weight of the 3rd, 4th, 5th and 6th instars was 47.11-134.18, 170.76-259.19, 141.51-317.33 and 78.24-334.93 mg lower than that of the control, respectively. By studying the effects of R. glutinosa on the growth, development, mortality and insect weight of H. armigera, the results showed that R. glutinosa had certain inhibitory effects on H. armigera, which lays a theoretical foundation for the effective utilization of weed resources in farmland to develop plant-derived insecticides.
