专化的

The producing time of sexuparae aphids by the cotton specialized aphids was earlier than that by the cucumber specialized aphids, whereas the apterous aphids produced by cucumber specialized aphids were significantly more than those by cotton specialized aphids.

结果表明：两寄主专化型棉蚜在产生有性世代能力上存在显著差异，表现为棉花型棉蚜在诱导后代中产生有翅蚜、雄性母和雌性母的比率显著高于瓜型棉蚜，并且雌、雄性母产生的时间明显早于瓜型棉蚜。

Acuminatum was only 2.1% after the identification. The monospore cultures of Fusarium from watermelon, Cucumis melo L., cucumber and Benincasa hispida var.

用西瓜、甜瓜、黄瓜及冬瓜上分离的尖孢镰刀菌(F.oxysporum)交叉接种在六种葫芦科作物上进行比较，证明引起上海地区西瓜枯萎病的病原菌是尖孢镰刀菌西瓜专化型(Fusarium oxy-sporum Schi.f.sp.niveum)。

The five major pathogenic fungi of three fruits rot diseases are : Dothiorella gregaria,Colletotrichum gloeosporioides,Trichothecium roseum,Macrophoma kawatsukai and Coniothyrium olivaceum. Ameng which Coniothyrium olivaceum is a new jujube pathgenic fungus.

从苹果、板栗、枣的病果上，分离到5 种病原真菌，其中Coniothyrium olivaceum 为枣果新病原－测定了6 种寄主上的Dothiorella gregaria 形态、酯酶同功酶及菌丝融合力，认为是一复合种，可区分为3 个专化型。

Barnyard grass, Echinochloa crus-galli, is one of the notorious weeds worldwide. To explore the potential of Alternaria augustiovoidea strain AAEC05-3 as mycoherbicide to control barnyard grass, the effect of inoculum potential and spray volume on the pathogenicity of strain AAEC05-3 to barnyard grass and host specificity of strain were studied using pot experiment.

为了确定稗草生防菌狭卵链格孢Alternaria augustiovoidea菌株AAEC05-3防除稗草的潜力，研究了其孢子接种浓度和喷液量对该菌株致病力的影响及菌株的寄主专化性。

Stylosa, but the pathogenicity of P II -3 was stronger than that of P I -1. The host range of P I -1 and P II -3 were the same. Their hosts were special to a certain extent. Only some species of mangrove such as Kandelia candel and Sonneratia apetala could be infected.

结果表明，菌株 P I -1和 P II -3均能引起红海榄赤斑病发生，但菌株 P II -3致病力比 P I -1的稍强；二者的寄主范围一致，均具有一定的寄主专化性，只能侵染部分红树植物如秋茄和无瓣海桑。

Gloeosporioides is an aggregative species and has differentiation within species, the pathogen probably is a microspecies under C. gloeosporioides and exhibited some specialized and selective qualities in pathogenicity. According to its symptom, the disease was named as angular leaf spot.

由于胶胞炭疽菌是1个集合种，存在分化现象，该病原菌可能是分化出的1个小种，并在致病性方面表现出一定的专化性或选择性，根据该病害的症状命名为板栗角斑病。

Phytopathogenic bacteria employ Hrp pathogenicity island to encode a specific typeⅢsecretion system that is required for bacteria and host plant interaction.

植物病原细菌利用Hrp致病岛编码专化性的Ⅲ型泌出系统，这个泌出系统是细菌与寄主植物互作时必要的调节因子。

The host plants will be damaged when infected by root-knot nematodes. The response of the host plants parasitized can also produce evident impact to the root-knot nematode, resulting in adaptation of the nematodes specific to different host plants.

此种寄生行为会对植物造成一定的伤害，而寄主植物的反应也会对根结线虫产生显著的影响，从而引发线虫的种种高度专化性适应。

Further experiments shows,there are 4 strains from those 8 Antagonism Antinomyces that can not only have good and stable inhibited about Banana Fusarium wilt disease No.4 race\'s mycelium,but also can inhibited the other 14 different F.sp.glycinea.

进一步试验表明，这8个菌株中有4个菌株不仅对香蕉枯萎病生理小种4号菌丝生长有良好、稳定的抑制作用，对另外14个不同专化型病原菌也有一定的抑制作用。

The results indicated that watermelon wilt disease was caused by F.oxysporum S...

黄瓜、甜瓜，冬瓜上分离的尖孢镰刀菌经交叉接种后，证明它们是不同的专化型。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
