| 中文摘要: |
| 为了研究控制茭白田福寿螺种群的方法,本文在调查不同茭白品种上福寿螺卵块分布差异基础上,开展不同规格(3、6、9 cm宽)竹片诱集福寿螺产卵试验。结果显示,不同茭白品种上福寿螺卵块分布数量差异大,单季茭白品种以‘杭州一点红’上卵块最多(11.6个/丛),远高于其他9个品种,最少的是‘八月茭’‘金茭1号’(分别为1.7、2.3个/丛)。双季茭白品种间的差异不显著,每个茭白品种上的卵块数在5.1~7.4个之间。不同规格竹片对福寿螺的产卵诱集效果差异大,引诱效果最好的为9 cm规格的竹片效果最差的是3 cm规格竹片。竹片凸面诱集到的卵块较多,凹面诱集到的卵块很少,竹片凸面朝田埂方向插入诱集产卵效果更好。福寿螺的产卵高度呈正态分布,主要集中在20~40 cm之间,未发现有靠近水面或在水下的卵块,卵块大小与数量呈线性正相关。研究结果为利用竹片诱集茭白田福寿螺产卵提供了技术依据。 |

| In order to find the method for controlling the population of apple snail in Zizania latifolia field, the experiment of trapping the snail to lay eggs on bamboo chips with different specifications (3, 6 and 9 cm width) was carried out based on investigating the differences in egg mass distribution of P. canaliculata on different varieties of Z. latifolia. The results showed that the distribution number of egg masses of P. canaliculata varied greatly among different varieties of Z. latifolia. The egg masses on the variety ‘Hangzhou Yidianhong’ of single-season Z. latifolia were the most (11.6/cluster), much higher than that on the other nine varieties, and the varieties ‘Bayuejiao’ and ‘Jinjiao No.1’ were the least (1.7 and 2.3/cluster, respectively). There was no significant difference between the double-season Z. latifolia varieties, and the number of egg masses on each variety was between 5.1/cluster and 7.4/cluster. The oviposition trapping effects of different specifications of bamboo chips on P. canaliculata are quite different, the bamboo chips with the width of 9 cm had the best trapping effect, while the lowest on chips with the width of 3 cm. The convex surface of bamboo attracted the most eggs, while the concave surface attracted few eggs. Inserting the convex surface of bamboo towards the ridge was better for attracting eggs. The spawning height of P. canaliculata was normally distributed, mainly between 20-40 cm. No egg masses near the water surface or underwater are found, and the size of egg masses was linearly and positively correlated with the number of masses. The results provide a technical basis for luring P. canaliculata to lay eggs in Z. latifolia field. |
