中文摘要:
      为了明确不同品种枣树对枣飞象 Scythropus yasumatsui 成虫寿命和繁殖的影响,筛选出枣飞象成虫适宜的枣树品种,以期为枣飞象建立人工饲养种群和综合治理奠定基础。在室内以木枣、狗头枣、赞皇枣、骏枣和酸枣分别饲养枣飞象成虫,研究不同品种枣树对枣飞象成虫寿命、产卵前期、产卵期、产卵量、卵孵化率和每雌子代数 的影响。不同品种枣树对枣飞象成虫寿命有明显影响,取食木枣的雌、雄虫寿命最长,分别为 36.6 ± 1.15 d 和 32.3 ± 1.61 d,取食酸枣雌、雄虫寿命最短,分别为 29.8 ± 1.55 d 和 25.6 ± 1.64 d。不同品种枣树对枣飞象成虫 产卵前期和产卵率没有明显影响。取食木枣和狗头枣的枣飞象成虫产卵期明显长于赞皇枣、骏枣和酸枣,取食木 枣的枣飞象成虫产卵量和每雌子代数最高,分别为 76.3 ± 2.87 粒和 67.0 ± 2.7 头,显著高于其它 4 种枣树,说明 木枣对枣飞象成虫产卵期、产卵量和每雌子代数有明显影响。在室内饲养枣飞象成虫,木枣是最适宜饲养枣飞象成虫的枣树品种。
英文摘要:
      The purpose of this study was to determine the effects of different jujube cultivars on the longevity and reproduction of Scythropus yasumatsui adults,and to select suitable jujube cultivars for jujube weevil. It is expected to lay a foundation for the establishment of artificial breeding population and comprehensive management of jujube weevil. The effects of different jujube cultivars on the longevity,pre-oviposition period,oviposition period,fecundity,egg hatchability and number of offspring per female were studied by feeding the adults of S. yasumatsui,with Muzao,Goutouzao,Zanhuangzao,Junzao and Suanzao in the laboratory. The results showed that different jujube cultivars had obvious effects on weight of S. yasumatsui adults ( P < 0.05). The longevity of female and male weevils fed on Muzao were the longest,which were 36.6 ± 1.15 d and 32.3 ± 1.61 d,respectively. The longevity of female and male weevils fed on Suanzao were the shortest,which were 29.8 ± 1.55 d and 25.6 ± 1.64 d,respectively. Different jujube cultivars had no significant effect on the pre-oviposition period and egg hatchability of female weevils. The oviposition period of female weevils fed on Muzao and Goutouzao was longer than Zanhuang,Junzao and Suanzao. The number of eggs laid and offspring per female of S. yasumatsui feeding on Muzao were 76.3 ± 2.87 eggs and 67.0 ± 2.7 head,respectively,which were significantly higher than those of the other four jujube cultivars. The results indicated that Muzao had significant effects on oviposition period,the number of eggs laid and offspring per female of S. yasumatsui. Muzao is a suitable jujube variety for raising the adults of S. yasumatsui in the laboratory.
