| 中文摘要: |
| 绿额翠尺蛾Thalassodes proquadraria （Inouce）是为害荔枝、芒果等热带果树的重要害虫。本研究在室内条件下(温度24～28℃、湿度 70%～90%）观察了荔枝、芒果、龙眼、莲雾等11种热带果树对绿额翠尺蛾发育历期及繁殖的影响。实验结果表明：在荔枝、芒果、龙眼、莲雾等4种热带果树上绿额翠尺蛾均能完成世代发育及后代能正常繁殖，为其寄主植物，菠萝蜜、杨桃、香蕉、番荔枝、枇杷、番石榴、柑橘不是其寄主植物；取食龙眼的世代历期和成虫寿命最长，显著长于荔枝、芒果、莲雾，存活率和产卵量也存在显著差异；种群趋势指数( I) 从大到小依次为：荔枝＞ 芒果＞ 莲雾＞龙眼,说明荔枝是绿额翠尺蛾最适宜的寄主，其次是芒果和莲雾，龙眼是最不适宜的寄主。 |
| 英文摘要: |
| Thalassodes proquadraria Inouce is an important pest of tropical fruit trees such as litchi and mango and so on. Under controlled conditions in the laboratory (T:24～28℃, RH:70%～90%), the effects of 11 species of tropical fruit trees on developmental duration and reproduction of T. proquadraria were studied. The results showed that T. proquadraria could complete generation development and normal offspring bred on the mango, litchi, longan and wax apple, which were host plants of T. proquadraria, while jackfruit, carambola, banana, sugar apple, loquat, guava, citrus were not host plants. The generation time and adult longevity of T. proquadraria fed on longan were the longest, compared with litchi, mango and wax apple. There were also significant differences in the survival rates and fecundity for T. proquadraria fed on the 4 host plants. The indexes of population trend for four host plants were ranked in the order of litchi>mango> Wax Apple >longan. The results suggest that litchi is the most suitable host plant, followed by mango and wax apple and then longan.. |
