| 为明确高温条件对芙新姬小蜂Neochrysocharis formosa (Westwood) 成虫寿命以及行为的影响, 以美洲斑潜蝇Liriomyza sativae Blanchard 2龄末至3龄初幼虫为寄主, 在补充非寄主食物20%葡萄糖溶液的情况下, 观察了芙新姬小蜂雌成虫在26?30℃和35℃ 3个温度下的寿命及对美洲斑潜蝇的取食致死数?叮蛰致死数?寄生致死数和总致死数?结果显示:与26℃相比, 高温条件(30℃和35℃)下, 单头雌虫的日均取食致死数?日均叮蛰致死数?日均寄生致死数?日均总致死数均显著升高, 并在35℃达到最高值, 分别为9.6?12.2?5.5头和27.3头?芙新姬小蜂雌成虫的寿命随着温度升高而显著缩短, 26℃下的寿命(21.4 d)约为30℃下寿命(11.4 d)的1.9倍和35℃下寿命(9.6 d)的2.2倍?3个温度下雌成虫一生的取食致死数?叮蛰致死数?寄生致死数?总致死数均无显著差异, 总寄主致死数均达230头以上?表明35℃高温对芙新姬小蜂控制美洲斑潜蝇的总潜力没有显著影响? |
| 英文摘要: |
| To evaluate the impact of high temperatures on the longevity and biocontrol behavior of Neochrysocharis formosa (Westwood), the late 2nd-instar and the early 3rd-instar larvae of Liriomyza sativae Blanchard were used as hosts to investigate the longevity, average number of host-feeding events, host-stinging events, parasitism events, and total host-killing events of N. formosa at 26℃, 30℃, and 35℃ under the supplementation of 20% glucose solution. The results showed that, compared to 26℃, the average number of daily host-feeding events, daily host-sting events, daily parasitism events, and daily host-killing events per female increased significantly at higher temperatures (30℃ and 35℃), reaching a maximum of 9.6, 12.2, 5.5, and 27.3 larvae at 35℃, respectively. However, the longevity of parasitoids decreased significantly with increasing temperature, with the longevity at 26℃ (21.4 d) being approximately 1.9 and 2.2 times longer than those at 30℃ (11.4 d) and 35℃ (9.6 d). There was no significant difference in host-feeding events, host-sting events, parasitism events, and total host-killing events per female adult in their lifetime under three temperatures, and the total host mortalities were over 230 larvae at each temperature. In conclusion, high temperature (35℃) does not significantly affect the biocontrol potential of N. formosa |
