蓝色杯诱捕落叶松球果花蝇的林间试验

Blue cup trapping of larch cone flies Strobilomyia spp.).

1996～ 1998年 ,在黑龙江省大兴安岭加格达奇落叶松种子园内 ,用蓝色杯诱捕器对落叶松球果花蝇进行了诱捕试验 ,进一步验证了其有效性 ;进行了换杯与不换杯的诱捕比较 ,结果表明 ,在 3～ 4周的诱捕期内换杯与不换杯的诱捕结果没有明显差异。

The blue cup trapping experiments were carried out in larch seed orchard in Jiagedaqi of Heilongjiang Province in 1996 to 1998. Blue cup is effective on trapping larch cone flies and this approves of the experiment results before. There is a little variation in trapping efficiency among cups shifted or unshifted for 3—4 weeks.
