陕西省眼蕈蚊科九新种(双翅目:长角亚目)

眼蕈蚊科(Sciaridae)为小型色暗的蚊类,常见于林间荫蔽处、夜晚飞集灯光下;幼虫体细长、白色、头部黑色、生活在腐殖质及土中常为植物地下根茎的重要害虫,许多种类为害菌蕈、对蘑菇种植是最严重的虫害。 陕西省的此类昆虫缺乏记载,1985年随周尧教授赴陕南宁陕县火地塘考察时,采集到一些种类,又从西北农业大学的收藏中检出若干标本,经制片研究共计九个新种。

韭菜迟眼蕈蚊的识别与防治

韭菜迟眼蕈蚊(Bradysia odoriphaga Yang et Zhang)俗称韭蛆、韭菜蛆、根蛆等,属双翅目、长角亚目、蕈蚊总科、眼蕈蚊科、迟眼蕈蚊属[1],不仅为害韭菜,还可为害百合科、菊科、藜科、十字花科、葫芦科、伞形科等多种蔬菜以及食用菌[2-5],其中以百合科的韭菜、洋葱、大蒜、韭葱、香葱等受害最重[6-7],在生菜上发生亦较重。因其在地下隐蔽危害和世代重叠等原因,防治困难,造成违规用药严重,引发食品安全、社会安全及生态安全问题。

桑橙瘿蚊发生调查与综合防治技术探讨

桑橙瘿蚊属双翅目、长角亚目、瘿蚊科,是以幼虫吸食桑枝顶芽汁液的微体害虫。危害轻时（每芽1～2头虫）,顶芽歪曲,生长受阻;危害重时（每芽3头虫以上）,顶芽黑枯、腐烂,枝条层层分叉,严重影响桑叶产、质量。该虫自1987年首次在睢宁县发生危害以来,曾多次暴发,是睢宁县桑树主要害虫之一,也是目前为止最难预测、最难防治的桑园害虫。

蚊子,你知道多少种?

需要了解蚊子的种类,我们首先得知道,蚊子是什么。让分类学家来说,蚊子是双翅目长角亚目的昆虫;而翻译成普通汉语的话,就是那些看上去只有1对翅膀(因为第2对翅特化成为了平衡棒),而且触角长于头胸之和的昆虫。蚊子的种类很可能远超你的想象,有数万种之多。而在这庞大的长角亚目中,我们熟悉和憎恶的蚊子,其实只是很小的一个分支。
