河南省绿盲蝽和中黑盲蝽春季迁移能力的铷标记研究

Using the Rb marking technique to track the spring migration of Apolygus lucorum and Adelphocoris suturalis in Henan

利用铷标记方法对河南省绿盲蝽Apolygus lucorum(Meyer-Dür)和中黑盲蝽Adelphocoris suturalis Jakovlev的春季迁移现象进行了研究。结果表明:在河南省2种棉盲蝽均有较强的迁移能力。绿盲蝽2 d内可迁移2 560m(试验最远回捕距离),中黑盲蝽6 d内可迁移5 120 m(试验最远回捕距离)。本文提供了春季绿盲蝽和中黑盲蝽由越冬场所向棉田转移的直接证据。

The spring migration of Apolygus lucorum （Meyer-Dtir） and Adelphocoris suturalis Jakovlev was investigated with the Rb marking technique. Direct evidence for immigration into cotton fields from overwintering sites during spring was found. Both species were highly mobile; A. lucorum was capable of moving at least 2 560 m within 2 days and A. suturalis 5 120 m within 6 days. These are the longest insect migrations from overwintering sites so far recorded in Henan Province.
