Tetranychus lintearius
Dufour, 1832



在一株荊豆上以其保護絲包裹的葉蟎。


葉蟎为葉蟎科葉蟎屬下的一个种。本物種被用於控制雜草的生長，主要是荊豆。


本物種體長約0.5毫米，顏色鮮紅色。群居於用吐出來的絲環繞樹枝尖端，以提供有遮蔽的地方。受感染的植物很容易可以找到這些被絲包圍的枝葉，有時還會愈長愈大。一般來說，本物種在其三到四週的成蟲生涯中每天都會下一到四顆卵，一年内能繁殖10到20代，從十數隻到數十隻的群體。初成長的幼蟲由於體型極微細，可以隨風擴散；餘下的會繼續繁殖。


本物種原生於歐洲，在當地一般被視為害蟲；不過本物種只會在特定植物出現，不會襲擊其他植物，即使有破壞，也只是在進食時刺穿植物的組織。不過被本物種嚴重侵佔的植物，往往會減少開花的機會，也令其枝葉生長受到限制。


本物種現時在整個澳大利亞，包括塔斯曼尼亞也造成傷害。然而在1990年代，本物種被引進到美國西北部及夏威夷，以控制當地的野草。本物種其實也有其天敵，包括另一種蟎Phytoseiulus persimilis及瓢蟲科的Stethorus punctillium，皆可使其數量大幅減少。

Run scheduled task as local user group (not BUILTIN)

Image
0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
