Abstract: Objective To study a technique for the control of Forcipomyia taiwana on Axonopus compressus grassland in an urban park. Methods On April 15, 2021, four types of grass trays where F. taiwana could oviposit and breed were placed in the outdoor environment of Futian Mangrove Ecological Park, Shenzhen, China:an A. compressus tray with a soil mulch of small pebbles, an A. compressus tray with a mulch of broken pine barks, an A. compressus tray without any soil mulch, and a Zoysia tenuifolia tray. After 75 days, these trays were moved to the laboratory of School of Life Sciences, Sun Yat-sen University, and were placed into insect cages to rear F. taiwana. Adult F. taiwana midges were collected and counted by sex. The emergence of adult F. taiwana was compared using non-parametric tests and analysis of variance between A. compressus trays with pebble and pine bark mulches, and using the two-sample t test between A. compressus and Z. tenuifolia trays without any soil mulch. One-way analysis of variance was used to compare the numbers of male and female adult F. taiwana emerging from the trays with different soil mulches. Results There was a statistical difference in the numbers of adult F. taiwana emerging from the pine bark-mulched A. compressus tray (3.00±0.92), pebble-mulched A. compressus tray (8.50±2.37), and A. compressus tray without any mulch (26.00±7.23) (F=6.735, P=0.007). The number of adult F. taiwana was higher in the A. compressus tray without any mulch (26.00±7.23) than in the Z. tenuifolia tray (12.00±3.33), but without statistical significance (t=1.719, P=0.111). There was no statistical difference in the number of male and female adult F. taiwana from any grass tray (all P>0.05). Conclusion Applying a pebble or pine bark mulch onto A. compressus grassland is effective to control F. taiwana, and the pine park is superior to pebbles. Compared with A. compressus grassland, Z. tenuifolia grassland cannot significantly reduce the breeding density of F. taiwana.

摘要: 目的 研究城市公园内人工种植的大叶油草地控制台湾铗蠓的技术方法。方法 2021年4月15日,在深圳市福田红树林生态公园户外放置4种台湾铗蠓可在其中产卵孳生的草盘(大叶油草土壤表面铺设小石卵、大叶油草土壤表面铺设松木皮、大叶油草、细叶结缕草)。75 d后移入中山大学(南校区)生命科学学院实验室,在养虫笼中培养草盘中羽化出的台湾铗蠓,统计台湾铗蠓成虫数量并区分雌雄。采用非参数检验和方差分析比较铺设小石卵和松木皮的大叶油草盘中台湾铗蠓的羽化量差异;采用双样本t检验比较台湾铗蠓在大叶油草和细叶结缕草草盘上的羽化量差异;采用单因素方差分析不同土壤覆盖物条件下的台湾铗蠓雌雄羽化数量差异。结果 铺设松木皮和铺设小石卵的大叶油草盘与仅有大叶油草的草盘之间台湾铗蠓的羽化数量分别为(3.00±0.92)、(8.50±2.37)和(26.00±7.23)只,差异有统计学意义(F=6.735,P=0.007)。不铺设任何土壤覆盖物的大叶油草草盘中台湾铗蠓的羽化数量[(26.00±7.23)只]高于细叶结缕草草盘[(12.00±3.33)只],但差异无统计学意义(t=1.719,P=0.111)。不同土壤覆盖物条件下台湾铗蠓雌雄羽化数量差异无统计学意义(均P>0.05)。结论 在大叶油草地上铺放小石卵和松木皮对防制台湾铗蠓有效,其中松木皮效果好于小石卵。与大叶油草地相比,细叶结缕草地不能明显降低台湾铗蠓的孳生密度。
