摘要
为了解枣树花期的访花昆虫,更好地利用昆虫为其授粉,本文对山西运城市临猗县、晋中市太谷县和吕梁市临县3地枣树的访花昆虫进行了调查,结果表明:枣树访花昆虫共计23种,隶属4目12科。运城临猗与晋中太谷间群落相似性最高,相似性系数为0.27,属于中等不相似,其它为极不相似。日活动规律观察表明,膜翅目与双翅目都属于单峰型,活动高峰为9∶30-10∶00、7∶30-8∶00。同一生境下,喷施药剂会影响访花昆虫的数量,一天中喷施清水的枣树访花昆虫244头,喷施药剂的枣树访花昆虫仅61头。
To understand pollinator and the use of insect pollination in jujube florescence,flower-visiting insects were observed in Linyi county Yuncheng,Taigu county Jinzhong and Lin county Lvliang. The results Showed that 23 species were identified,belonging to 4 orders,12 families. Linyi and Taigu had the highest similar coefficient,others similar coefficient were not similar. The observation of daily activity pattern showed that Hymenoptera and Diptera belongs to unimodal type,the peak of Hymenoptera pollination at 9∶ 30- 10 ∶ 00,the peak of Diptera pollination at 7 ∶ 30- 8 ∶ 00. Under the same habitat,spraying pesticides can affect the number of flower-visiting insects at jujube florescence,244 insects on spraying water jujube,only 61 insects on spraying pesticides jujube in one day.
