初步研究了东亚飞蝗 (L ocusta migratoria manilensis (Meyen) )不同龄期蝗虫粪便挥发物对蝗蝻的聚集作用。利用自行设计制作的行为生测仪及其配套装置 ,在 (30± 2 )℃温度下 (均匀光照 ,湿度为 6 0 %左右 ) ,就蝗虫粪便挥发物对各龄蝗蝻的引诱及滞留活性进行了生测研究。结果表明 :蝗虫粪便挥发物对各龄蝗蝻都有一定的引诱作用和滞留作用。其中高龄蝗蝻粪便挥发物对同龄和低龄蝗蝻的聚集作用较好 ;群体测试时 ,可能由于虫体间视觉、触觉等的影响 ,蝗蝻对挥发物的敏感性下降 ,反应浓度阈值增加 ,但仍有较明显的聚集效果
Preliminary study of locust comatose volatiles from locusts in different stages of L ocusta migratoria manilensis (Meyen). Using the behavioral biometrics instrument and its ancillary equipment designed and produced by ourselves, the attractant and retention activity of locust excrement on locusts of all ages were studied under the temperature of (30 ± 2) ℃ (uniform light and humidity of about 60%) Health test. The results showed that locust excrement volatiles had certain attraction and retention effect to locusts of all ages. Among them, the excrement of the excrement of the locust stinkbug on the same age and young locusts gather better. In the group test, the sensitivities of the locust stool to the volatiles may decrease due to the visual, The more obvious aggregation effect
