摘要
采用直流刺吸电位仪EPG(direct current electrical penetration graph,EPG)技术分析西花蓟马Frankliniella occidentalis雌雄虫在4种寄主植物上的取食行为,探讨西花蓟马雌雄虫取食行为差异及与寄主适合性的相关性。结果表明:(1)西花蓟马在辣椒上的非取食刺探次数显著少于其他寄主植物。雌虫在辣椒、番茄、曼陀罗和矮牵牛上的非取食刺探分别为231.1,328.9,361.0和304.4次,雄虫在辣椒、番茄、曼陀罗和矮牵牛上的非取食刺探分别为152.7,277.2,221.4和196.8次。西花蓟马在矮牵牛上的短取食刺探显著高于番茄,雌虫在番茄和矮牵牛上的短取食分别为68.8和144.4次,雄虫在番茄和矮牵牛上的短取食分别为15.9和80.9次。西花蓟马在矮牵牛上的长取食刺探次数少于在其他寄主植物。(2)雌虫比雄虫产生更多的非取食刺探和短取食刺探,雄虫的长取食刺探显著高于雌虫。在矮牵牛上,雌虫的非取食刺探次数和非取食刺探总时间为雄虫的1.5倍。在番茄上,雌虫的短取食次数和短取食总时间分别为雄虫的4倍和2倍;雄虫的长取食次数和长取食总时间分别为雌虫的2倍和7倍。由此可见,西花蓟马的取食行为与寄主适宜性之间无显著的相关性。
The objective of this research was to study the relationship between the feeding behavior and the suitability of host plants for Frankliniella occidentalis,and was to demonstrate the difference of feeding behavior for males and females on the same host plant. The feeding behaviors for western flower thrips（ WFT） on tomato,pepper,stramonium and petunia were recorded using the direct current electrical penetration graph（ DC-EPG）. The results showed as follows：（ 1） The noningestion probes for WFT on pepper were significantly less than that on other host plants. The number of noningestion probes for females on pepper,tomato,stramonium and petunia was 231. 1,328. 9,361. 0 and 304. 4, respectively. The number of noningestion probes for males on pepper, tomato,stramonium and petunia was 152. 7,277. 2,221. 4 and 196. 8,respectively. Compared with tomato,the shortingestion probes for WFT was significantly greater on petunia. The number of short-ingestion probes for females on tomato and petunia was 68. 8 and 144. 4,respectively. The number of short-ingestion probes for males on tomato and petunia was 15. 9 and 80. 9. The long-ingestion probes on petunia were less than that on other host plants.（ 2） The noningestion probes and short-ingestion probes for females were more than those for males; however,the long-ingestion probe for males was more than that for females. The number and the duration of noningestion probes for females on petunia were 1. 5 times of that for males. Compared with females,the number and duration of short-ingestion probes for males was 4 times and 2 times of those for females on tomato,respectively. The number and the duration of longingestion probes for males were 2 times and 7 times of that for females on tomato,respectively. In conclusion,the feeding behavior of western flower thrips on host plants doesn＇t have close relation to the suitability of host plants.
