Cultivated and wild Cruciferae. It is widespread throughout Europe and much of Asia, North Africa, Australi

3、a, New Zealand, Hawaii, Canada, USA and Mexico. 2. Damage:The larvae feed singly, usually deep in the cabbage heart, making holes in the leaves, even eat up all leaf blade, only the main veins are left, with frass accumulation. The caterpillars prefer to feed in the heart of the cabbage and occasion

4、ally cause heavy infestations and partial defoliation. In Guangdong Province there may be 7-8 generations per year. 3. IdentificationAdult:Adult is a white butterfly with a wingspan about 45-55 mm in the female. The wings bear several black markings.Eggs:The bulletin-like eggs are laid singly on low

5、 surface of the leaves. There are many vertical ridges on the surface of egg.Larva: Fully-grown larva is about 30 mm long, velvety green with a faint yellow dorsal strip, and a row of yellow spots along each side in line with the spiracles. Pupa:The pupa is shuttle-like form, sharply angled, attache

6、d usually to the underside of the leaf by a loop of silk.,Eggs,Larva,Adult,Pupa,1.It is a totally polyphagous pest and feed on a very wide range of crops including vegetables, cotton, rice, tomato and tobacco. Other host plants include Citrus, cacao, sweet potato, rubber legumes, sorghum, maize etc.

7、2.Distribution:It mainly distributes in South and Eastern Old World tropics, including Pakistan, India, Bangladesh, Sri Lanka, China, Korea, Japan, Thailand, Vietnam, Philippines, Indonesia, Austral-Asia, Pacific islands, Hawaii and Fiji.3.Damage:This caterpillar is basically a leaf-eater. Heavy inf

8、estations can seriously defoliate the crops, especially the young plants. Newly hatched larvae are gregarious and remain together and skeletonize the leaf on which they feed. Later they disperse and become more solitary and nocturnal in habits. One generation can be completed in as little as 24-30 d

9、ays, and in the humid tropics there may be 8 generations annually. 4. Identification:Adult : The adults are pale brownish moth, with the yellow-brown forewing having a distinctive pale band medially: wingspan is 30-40 mm.Eggs:Eggs are spherical (0.3 mm) in diameter, and laid on the undersides of lea

13、uthern China, Philippines, Indonesia, and Canada.3.Damage:Young larvae eat foliage within webs underside of the leaves. The caterpillars are gregarious, moving in swarms, and destroying the young leaves and stems of the host plants. Young seedlings can be completely destroyed, but older plants often

14、 recover after an attack and may be still vigorously. Young larvae skeletonize the underside of the leaves, but later as they grow they eat the entire lamina. In South China there are usually eight generations. 4. Identification:Adult:The adult is a small brown moth of wingspan up to 25 mm, and the

15、fore wing is grayish-brown with two yellow spots near the center. The hind wing is a translucent white with narrow brown borders, There are rather nondescript in appearance and not easy to recognize. Eggs:Eggs are laid on the leaves of the host plants, in clusters, several layers thick, and covered

16、with hairs from the female abdomen. Each cluster contains 50-300 eggs, one female can lay 300-900 eggs (up to 1700). Eggs usually hatch after 2-4 days.Larvae: The larvae are very gregarious, at first green, later becoming variable green or brown usually with a lateral strip. Young larvae skeletonize

17、 the underside of the leaves, but as they grow they eat the entire lamina.Pupa:Pupation takes place in the soil and lasts about 6 days.,甜菜夜蛾Spodoptera exigua Beet Armyworm,Adult,Eggs,Larvae,粉纹夜蛾Trichoplusia niCabbage looper,Eggs,Larvae,蔬菜蚜虫Vegetable aphids,1 萝卜蚜 Lipaphis erysimi Turnip Aphid2 桃蚜 Myz

31、tefly,小菜蛾Plutella xylostella (L.)Diamondback Moth(DBM),俗称:小菜蛾、吊丝虫Common name: Diamondback moth分类地位:鳞翅目,菜蛾科 寄主:十字花科蔬菜和杂草以甘蓝、芥蓝、萝卜、西洋菜为害最重,白菜、油菜、芥菜次之。,简介,一、分布和为害,1、分布,以幼虫取食为害叶片,造成孔洞和缺刻。幼虫四龄。幼虫喜欢集中在心叶和花上为害。1龄幼虫潜叶。2 龄以上幼虫在叶背面啃食下表皮和叶肉,仅上表皮,俗称“开天窗 ” 。4龄暴食,占总食量的80%。严重时叶片被吃成网状仅留叶脉。,2、为害,明显的地域性热带、亚热带重于温带。大发生

32、频率越来越高自70年代以来已经成为南亚、东南亚和中国南方地区蔬菜上的主要害虫。由于化学杀虫剂的大量施用,抗性严重产生在深圳的菜场,所使用的化学农药中80%的是杀虫剂,其中又有90%用于防治小菜蛾,平均2-3天喷药1次。防治费用高全世界用于防治小菜蛾的费用每年高达10亿$。,3、发生为害特点,二、生物学特性,世代一年多代,发生世代由北到南不断增加。新疆、东北4-5代,华北5-6代,长江流域9-14代,广东19-21代。越冬在东北不能越冬,其虫源由南方迁飞而来。在长江流域以南无越冬现象,终年可以繁殖。发生高峰新疆:7-8月,华北、东北:5-6月,长江流域以南:双峰型,春、秋季节为害严重。,1、年发

33、生动态,生活史,成虫2-3 days,卵3-5days,幼虫8-15 days,蛹5-8 days,小菜蛾生活周期15-20 days,小菜蛾对温度有较强的适应能力对温度的适应范围广从0-35都能存活,最适温度为20-30,在8-33条件下均可产卵繁殖,在最适温度23时,在实验室内繁殖一代后可以增加77倍。在30 时繁殖最快,月增长倍数达1307倍。耐低温的能力较强幼虫在-1.4条件下照常取食,在0条件下可以忍耐42天 。小菜蛾有较强的扩散能力在国外有小菜蛾远距离迁飞的报道。,3、对温度的适应能力,成虫的选择性成虫喜欢选择含芥子油(硫代葡萄糖苷)高的蔬菜如萝卜,芥菜产卵。幼虫的选择性幼虫偏嗜叶

34、片较厚的芥蓝、甘蓝类,但对完成发育所需的营养要求不高,落叶、老叶、黄叶、残株甚至取食茎和叶柄都能完成发育。十字花科的连年、连片种植,为小菜蛾的发生提供了丰富的食物来源,是小菜蛾上升的一个重要原因。田园清洁的重要性。,4、对食料条件的要求,抗虫谱广对使用过的几乎所有杀虫剂都产生了抗性,甚至对Bt也产生了抗性。抗性发展快对有些杀虫剂只需1-3年就可产生抗性。抗性水平高对拟除虫菊酯台溴氰菊酯可产生上万倍的抗性。抗性的产生造成防治效果下降,促使用药量加大,最终导致小菜蛾陷入愈防愈重的恶性循环中。,5、对化学杀虫剂的抗性,三、环境条件对小菜蛾的影响,食物:十字花科作物,捕食天敌,寄生天敌,病原微生物,栽

35、培措施,气候条件,6、小菜蛾成灾原因分析,充足的食物来源:十字花科作物种植 面积的扩大。化学杀虫剂的大量使用,杀伤天敌,抗性的产生。小菜蛾本身的繁殖能力以及对环境条件的适应能力。,发生量预测虫源基数调查:在田间随机取样调查各虫态的数量。用性诱剂监测成虫数量。性诱剂购买。性诱剂自制:用酒精、苯、三氯甲烷提取雌蛾腹部。根据气候条件预测。发生期预测用上一代成虫高峰期推测下代幼虫高峰。用成虫高峰期推测幼虫高峰。,四、预测预报,五、防 治,农业防治 Cultural Control 生物防治 Biological Control 诱杀 Pheromone Trapping 化学防治 Chemical C

36、ontrol,1、农业防治,轮作 Crop rotation 将十字花科蔬菜中的早、中、晚熟品种,生长期长、短不同的品种与其它蔬菜轮留种植。间作 Intercropping与豆科、茄科等非十字花科蔬菜间隔种植。田园清洁 Field sanitation收获后及时清除和集中消处理残株、落叶和杂草,田块立即耕翻。,2、生物防治,引进天敌弯尾姬蜂 Diadegma semiclusum 颈双缘姬蜂 保护天敌寄生性天敌捕食性天敌 蚂蚁,蜘蛛 ,草蛉,叉角厉蝽,2、生物防治,增加释放天敌寄生性天敌 Parasitoids卵期: 拟澳洲赤眼蜂Trichogramma confusum幼虫期: 小菜蛾啮小蜂

38、低毒、低残留的农药。轮换用药,避免抗性产生。常用农药Bt制剂(可与杀虫双混用)、巴丹、安打(茚虫威)、菜喜(多杀霉素)、米满(虫酰肼) 、除尽(虫螨腈)、印楝素等。阿维辛、阿维高氯、氟虫腈毒死蜱等。,黄曲条跳甲Phyllotreta striolata,Stripped Flea Beetle,俗称:黄条跳蚤、狗虱虫Common name: Stripped flea beetle分类地位:鞘翅目,叶甲科 寄主:8科19种,偏嗜十字花科蔬菜包括白菜、萝卜、芥菜、油菜、甘蓝、芥蓝、花菜以及茄科、豆科、葫芦科作物。,简介,1、分布,常见有黄曲条跳甲、黄直条跳甲、黄宽条跳甲、黄狭条跳甲。国外分布于亚

39、、欧、北美等50多个国家。国内除新疆、西藏、青海外各省区都有分布,且虫口密度都很高。,成虫:成虫咬食叶片。常数十头成群在一张叶片上为害,尤以叶背为多,被害叶片布满稠密的椭圆形小孔。成虫取食为害叶片,造成孔洞和缺刻。成虫喜欢取食叶片的幼嫩部位,所以苗期受害最重。常造成毁苗现象。幼虫食根幼虫生活在土中,专门为害寄主植物的根皮,使其表面形成许多不规则的条状疤痕。同时咬断须根,使植株发黄萎蔫死亡。,2、为害,黄曲条跳甲为害状,自80年代以来大发生频率增加,在中国南方菜区变成了十字花科蔬菜的主要害虫,在有些地方甚至超过了小菜蛾。广谱性杀虫剂的使用使其产生严重的抗性。没有有效的防治方法,喷施杀虫剂仍然是主

40、要的防治手段。,3、发生为害特点,二、生物学特性,世代一年多代,发生世代由北到南不断增加。新疆、东北2-3代,华北3-5代,长江流域4-6代,广东7-8代。越冬在南岭以北以成虫匍匐于地面的菜叶下面或残枝落叶、杂草中越冬。华南地区无越冬现象,终年可以繁殖。发生高峰双峰型,春、秋季节为害严重。,1、年发生动态,生活史,成虫4-9 days,卵3-9days,幼虫11-16 days,蛹 10-14 days,黄曲条跳甲生活史28-48 days,土中,地上,活动习性活泼,善于跳跃,高温时能飞翔。早晚或阴天躲藏于叶背或土块下,中午前后活动最盛。趋性趋光性:成虫有较强的趋光性,对黑光灯特别敏感。趋黄性

41、:成虫有较强的趋黄光性黄板诱虫法。趋嫩性:常集中于幼嫩的心叶为害。,2、成虫习性,寿命成虫寿命极长,平均50天,最长可达一年。世代重叠的原因。产卵习性产卵期较长,可达30-45天,产卵前期4-9天。产卵时间多为晴天中午的前后。卵散产于植株周围3厘米左右的湿润土壤中或细根上。产卵量一般来说100-150粒/雌,越冬代可达到620粒/雌。卵在土壤中的分布是个体群。,2、成虫习性,幼虫共3 龄,在土内栖息的深度与作物根系分布有关。从须根向主根,从上向下。无转株为害习性。在土壤中的分布与卵一样,属于聚集分布。其基本成份是个体群。蛹老熟幼虫多在3-7厘米深的土壤中作土室化蛹。,3、幼虫及化蛹习性,5、对

42、湿度的要求,卵孵化要求较高的湿度,不到 100%的相对湿度多数卵不能孵化。沟边的菜地由于湿度大而发生重。湿度大的春季为害重。含水量多的壤土和粘土比砂土重。,6、对寄主植物的选择性,成虫取食的选择性,菜心芥菜萝卜 芥蓝,五、防治 CONTROL,农业防治 Cultural Control 生物防治 Biological Control 成虫诱杀 Adult Trapping 化学防治 Chemical Control,1、农业防治,田园清洁及时清理残株落叶。轮作与非十字花科蔬菜轮作。深翻土壤 -播种前7-10天深翻土壤晒垄或用大水浸田。间种紫苏,2、生物防治,病原线虫用斯氏线虫Steinerne
