发生规律分布在全国各地,从北到南发生2 ~ 6代(黑龙江2 ~ 3代,辽宁3 ~ 4代,陕西4代,江西,湖南5 ~ 6代),因蛹在泥土中过冬。益春羽化成虫在幼苗附近的土票或黄瓜幼苗根部产卵,孵化出来的蛆钻进作物的嫩茎,使作物因水分不足而枯萎,后来逐渐腐烂枯萎死亡。本种为第一代,损失严重,部分年份发生在秋季,第四代和无地蝇混杂在一起,危害白菜和萝卜。成虫在晴天中午前后最活跃,对尚未成熟的粪肥和发酵的糕肥有很强的趋势性。
禁止将生粪用作肥料。即使使用成熟的有机肥,也要均匀而深入(最好做底肥),将种子和肥料分开,还可以在粪肥上涂上毒土。地球仪的严重隔间应尽可能改用活性有机肥或酶菌制成的堆肥。成虫发生期间,75%灭蝇胺杀虫湿粉5000倍,或10%灭蝇杀灭显影剂1000倍,间隔7天,连续喷洒1次,2 ~ 3次。发生蛆的菜园可以使用48%的毒油l500倍液,或者50%的辛硫磷乳油l000倍液灌溉,每亩约05~lkg。毒死蜱收获前7天停止使用药物。蚯蚓是多食性害虫,喜欢吃各种蔬菜,对蔬菜苗床和移植后蔬菜苗特别有害。
成虫和若虫咬泥土上刚撒下的种子和芽,或咬下幼苗的根和茎,使幼苗枯萎死亡,受害的根乱成一团。活跃在地下的蚯蚓将表层土钻入许多隧道,分离幼苗根部的通风和土壤,使幼苗因脱水而死亡,幼苗断沟,严重,甚至破坏种子。成虫和幼虫都有可能受到伤害,成虫在叶片前吃后产卵,幼虫在叶片正面潜入叶和叶柄造成伤害,叶表皮出现典型蛇行虫,一般不通过叶脉,享受枝叶、豆科、葫芦、菊科等,不能伤害花本科。
成虫利用产卵期将卵生在叶子上,孵化出来的幼虫在叶子和表皮之间蚕食叶肉,虫体粗,经常呈块状,不连贯,寄主范围广,喜欢吃豆类、葫芦科、茄科、菊科、苋科等。成虫在叶前取食产卵,刺破叶细胞,幼虫孵化后蚕食叶肉,呈弯曲的食痕,虫卵可通过叶脉,分布黑色条粪,寄主范围比较窄,主要发生在枝和作物上。虫道不规则地延伸到上壳,终端不明显地宽,有菊科、南瓜科、豆科、茄子科等,其中香芹是其寄主。

jay sean - I'm gone
gone im gone
gone im gone
I don't want to have to see you happy
I can't even bare to see you smile
Now-a-days I can't look in your eyes &
Well I can but it takes a while
If you're strong
Told a lot of white lies to hide it all
But they're beginning to break me down,
Though I promise it's over now
I'm gone
I don't blame you at all
'Cause after all the things that you did for me
Got beaten by temptation
I'm gone
Girl you're better off alone
I don't want you to see, the truth in me
Try my best to keep it all together
Tryna take it back to where we were
Never been to good at keeping secrets,
Give you reasons but for what it's worth
Let me go
What the hell would make you look at me the same
Used to say "We're unbrakeable"
But I just went & changed it all
If I told you
Could you live with that
If I told you
Could you live with that
If I told you,
I couldn't live with that!
I couldn't live with that!
Noooo!
I'd rather give you no excuses at all
I'm gone
I don't blame you at all
'Cause after all the things that you did for me
Got beaten by temptation
I'm gone
Girl you're better off alone
I don't want you to see, the truth in me
You gave everything & honestly
it's every fault of mine
To beg you for forgiveness just seems wrong
See, leaving you is one thing
But you've got to realize:
Some things are best unspoken
So please don't ask me why!
Oh, you don't want to know
Oh, woah
I'm gone
I don't blame you at all
'Cause after all the things that you did for me
Got beaten by temptation
I'm gone
Girl you're better off alone
I don't want you to see, the truth in me
If I told you
Could you live with that
If I told you
Could you live with that
If I told you,
I couldn't live with that!
I couldn't live with that!
Noooo!
If I told you
Could you live with that
If I told you
Could you live with that
If I told you,
I couldn't live with that!
I couldn't live with that!
Nooooooooooooo!
Oh, ooooh
No no
No no
Oooh, woaah
Ooooooooooooh
Yeah, yeah, yeah
Oh oh
Oh woah, oh woooah

近几年来, 自称融合了Access和Excel以及易表优势的FoxTable势头越来越盛,在其宣传中,矛头直指Excel和Access,用了一些诸如“还在用Access落伍了!”、“FoxTable上市,秒杀Excel”之类的以贬低微软产品而抬高自身的宣传,大有不妥之处,为什么呢?
第一:混淆套件和单个组件的概念
如若将FoxTable单独与Excel或Access对比,这是不公平的,为什么呢?因为从功能上说,FoxTable是集成的套件产品,而Excel或Access是仅是OFFICE软件中的一个组件,以套件的集成功能去比人家的单个组件,这就好比用一辆汽车去和一个汽车轮子相比——即便这个汽车轮子造的再好,怎么能和一辆完整的汽车相比呢?所以,在这一点上,FoxTable明显是偷换了概念,如若真要想比,FoxTable应该和微软公司的Office软件去比较——FoxTable有协同功能,难道Office就没有协同功能么?显然,从整体上说,显然是不能比的,别的不说,单是一个PPT组件,FoxTable就不具备,所以,FoxTable的宣传,明显偷换了概念;
第二:混淆了开发平台和办公软件的概念
随着软件产品的持续、深入地发展,一些可以反复利用的各类模块组件不停被开发人员整理和归纳出来,而集模块之大成者,便是由各个功能各异,又可以形成一个完整的多个模块的组合,这便是如今渐为人们所熟知的开发平台,FoxTable明显是属于开发平台,而Access或者Excel,则明显属于办公软件一类,而由于办公软件的特性,便是要尽可能地提供便捷性、可拓展性,因而,对于开发平台而言,过大的灵活性必然要牺牲很多功能性的成长。因此,从开发角度来说,开发平台肯定比办公软件要好用,但是从便捷性、可拓展性来说,开发平台肯定是不能和和办公软件相比的。
第三:功能性和稳定性的权衡
从软件产品和开发工具的角度来说,功能性固然是重要的,可是,其稳定性也是很重要的(有些场合,稳定性甚至超过功能性的要求,比如金融系统以及保密性要求比较高的各类系统),这就好比是汽车、飞机,固然要求其功能多样,可以驾驶,便于维修,损耗不是太大,可是,如若其稳定性不佳,那么,大约也是没有多少人敢用的——所以,一款软件产品,单单强调其功能,这是不客观的,所以,稳定性也是很重要的一个方面。
如若要对比稳定性,刚刚问世没有几年的FoxTable能和有着十多年历史的Access和Excel相比么,恐怕是不可能的吧?
计算机软件作为辅助工作的一个工具,从应用性来看,100个企业中,有多少个企业在用微软的offcie(Excel、Access)有多少个企业在用FoxTable?相信大家心中自明。
综上所述,用Access、Excel并不落伍,也不可能被FoxTable秒杀,倒是其在宣传自身产品时“贬低别人,抬高自已”的理念值得商榷。
