摘 要:【目的】探究试验条件下田间种植抗蚜品种对昆虫的种类和数量造成的影响,为将来抗蚜品种推广后拟采用的植保栽培措施提供指导。【方法】在抗蚜地块早春不防治蚜虫和对照地块正常防治蚜虫的情况下,利用马来式网收集法、昆虫性诱剂诱捕法和目测调查法,在昆虫主要生长季节(3—8月),对抗蚜地块和对照地块内的昆虫群落组成和昆虫群落个体数量的动态变化进行分析。【结果】全生长季节抗蚜地块共诱集到昆虫5955头,分属9个目;对照地块共诱集昆虫4606头,分属8个目。抗蚜地块诱集到的昆虫总数大于对照地块,抗蚜地块前期(3月下旬至6月下旬)诱集到的昆虫总数大于对照地块,后期数量基本一致。与对照地块比较,抗蚜地块中的优势昆虫种群(双翅目、半翅目、鳞翅目和膜翅目)的昆虫总数存在发生高峰提前和总数增加的趋势。两地块诱集到的昆虫总数随时间变化趋势一致。抗蚜地块中的多数中性昆虫和天敌昆虫的数量也存在发生高峰提前和总数增加的趋势。两地块益、害虫比无明显差异。【结论】因早春未防治桃蚜,抗蚜品种的应用会出现田间昆虫总数增多的现象,了解抗蚜地块内昆虫群落的发生规律,为未来抗蚜品种应用推广采用适宜的植保措施提供了有益参考。

桃[Prunus persica(L.)Batsch]是原产我国的世界性重要落叶果树,栽培历史悠久,适应范围广,经济效益高。在中国果业中仅次于柑橘、苹果和梨,居第四位。桃蚜(Myzus persicae Sülze)是桃树早春的主要害虫之一,对桃产业危害严重。目前中国农业科学院郑州果树研究所已经培育了多个桃树抗蚜品种,正处于区试和品种保护阶段。应用桃树抗蚜品种能有效防治桃树桃蚜危害,在桃树抗蚜品种大规模推广前,对抗蚜品种田间昆虫种类和数量的变化趋势进行研究,可为抗蚜品种配套植保措施的制定提供必要信息。

桃蚜通常以若虫、成虫群集于桃树新梢幼嫩叶片背面刺吸汁液造成叶片卷缩,无法抽出嫩梢。桃蚜分泌的蜜露污染植物叶片,易引起煤污病,影响植物光合作用。此外,桃蚜还是植物病毒病的携带者和传播者[1]。由于桃蚜具有繁殖快、个体小、生活周期短的特点,在生产上需要花费大量的人力物力多次喷施农药进行防治,长期使用农药不仅会使桃蚜对农药产生抗药性,还给环境带来了巨大的化学污染。因此,利用桃树自身抗性防控桃蚜是最环保和经济的一种方式。

在过去50到60年里,植物育种家和昆虫学家在使用传统的植物育种方法培育抗虫作物品种方面取得了较大的成功,在自然界中发现了许多对昆虫有抗性的资源品种[2]。植物的抗性是由昆虫诱导的植物蛋白质和抗性基因产物合成的防御化物质介导的。利用克隆和分子定位已确定Mi-1.2Vat 节肢动物抗性基因为CC-NBS-LRR(coiled coil-nucleotide binding site-leucine rich repeat)亚家族NBS-LRR抗性蛋白,以及多个抗性基因类似物。遗传连锁定位已识别出100多个用于品种培育的植物抗性基因位点和连锁分子标记[3-6]。目前,在世界范围内,已从桃种质资源中鉴定出多份抗蚜材料。法国农科院鉴定了5种抗蚜种质,其中“垂枝花桃”(Weeping Flower Peach,WFP)和桃砧木品种Rubira 分别由显性单基因位点Rm1Rm2 控制,山桃为多基因控制,主效基因定位在3号染色体上[7-9]。王力荣等[10]采用田间自然筛选和人工接种相结合的方法,对国家果树种质郑州桃圃保存的419 份资源进行了抗桃蚜鉴定,筛选出了寿星桃、碧桃抗性较强的种质资源。笔者课题组培育出多个桃树的抗蚜品种并且对蚜虫的抗性效果显著[1,11-14]。我国抗虫品种研发成果丰硕,近年来抗虫作物陆续被批准商业化生产,世界范围内迄今已有200余个带有抗虫性状的转基因玉米品种被批准商业化生产[15]。20年来,我国共批准3188个转基因抗虫棉生产应用安全证书,其中,2572 个获得品种审定[16]。抗虫棉的应用不仅能有效控制棉铃虫对棉花的危害,还能减少棉铃虫对其他作物的危害[17-18]。相对于常规棉花,抗虫棉的种植降低了农药使用量、减少了防治成本[19-21]。但是随着抗虫棉的大量种植,一些非靶标害虫(如棉蚜、棉盲蝽、烟粉虱等)因农药施用量减少而出现大暴发的现象[22-24]

已有研究表明如BT 棉等抗虫作物在长期种植过程中会影响田间非靶标害虫种群种类和数量,导致次要害虫升级为重要害虫,从而影响作物害虫防治的周年规律[25-32]。目前桃树抗蚜品种种植对田间昆虫群落结构的影响尚缺乏研究。为此,笔者在本研究中对桃树抗蚜品种种植后田间昆虫群落种类和数量变化进行调查,旨在探明抗蚜品种的应用推广对除桃蚜外的昆虫种类和数量造成的影响,为将来抗蚜品种应用推广后可采用的植保措施提供科学参考和理论依据。

1 材料和方法

1.1 试验时间、地点

试验于2022 年3—8 月在中国农业科学院郑州果树研究所新乡综合试验基地桃育种课题组育种圃进行。

1.2 试验材料及处理

供试材料选用感蚜品种中油13 号和抗蚜品种中蟠1 号(抗性来源于寿星桃,属于I 类抗性),由中国农业科学院郑州果树研究所桃育种课题组提供。

试验共设2个处理,分别为抗蚜地块(种植抗蚜品种中蟠1 号)和对照地块(种植感蚜品种中油13号)。两个地块面积相同,地块内桃树的株行距1 m×3 m,3 年生树,树形为主干形,桃树地面自然生草。对照地块正常防治桃蚜,在桃蚜发生季节使用2 次防治蚜虫的农药,于桃树花露红时(3 月14 日)第1次喷施农药,种类为22%氟啶虫胺腈悬浮剂10 000倍液和20%氯氰菊酯水乳剂600 倍液;于桃树落花后(4月7日)第2次喷施农药,种类为22%氟啶虫胺腈悬浮剂10 000 倍液、20%氯氰菊酯水乳剂600 倍液、22.4%螺虫乙酯悬浮剂6000 倍液和500 g·L-1甲基硫菌灵悬浮剂400倍液。抗蚜地块内不针对蚜虫进行化学防治。此外,针对该桃园往年危害桃树严重的梨小食心虫和红蜘蛛进行化学防治,于4 月10日喷施35%氯虫苯甲酰胺水粉散粒剂7000 倍液防治梨小食心虫,于7月1日喷施10%乙螨唑和20%联苯肼酯悬浮剂5000倍液防治红蜘蛛。

1.3 试验方法

调查采用马来式网收集法、昆虫性诱剂诱捕法和目测法。每隔10 d 左右收集1 次,将收集到的昆虫标本带回实验室进行初步的分类和鉴定,将昆虫鉴定到目。

马来式网收集法:按照均匀分布原则,在每个地块安装1 个马来式网,3 次重复,两个地块共安装6个马来式网。昆虫被诱集于装有75%乙醇的塑料瓶中,保持了昆虫的原始形态,收集后及时更换收集瓶。

昆虫性诱剂诱捕法:每个三角形诱捕器配置1枚诱芯,距地面150 cm。每个地块设4种诱芯处理,每处理2 次重复,两个地块共16 个诱捕器。每个地块内的诱捕器均匀分布,隔21 d 统一更换诱芯。每隔7 d调查并记录诱捕器诱捕到的昆虫数量,并重新清理干净。

目测法:每个地块内随机抽取5 株树,3 次生物学重复,目测调查并记录每棵树上梨小食心虫的虫梢数。

1.4 标本鉴定

参照《中国动物志:昆虫纲》[33]、《中国昆虫生态大图鉴》[34]、《桃病虫害快速鉴别与防治妙招》[35]等分类参考书对收集到的昆虫标本鉴定到目。

1.5 数据统计分析

采用Microsoft Excel 2019进行数据整理分析和曲线图绘制。

2.5 抗蚜地块和对照地块内梨小食心虫虫梢数的动态变化

抗蚜地块和对照地块内的梨小食心虫的虫梢数随时间变化趋势基本一致。在抗蚜地块中,梨小食心虫的虫梢数从4月中旬开始迅速增加,6月下旬达到峰值,之后逐渐下降。在对照地块中,梨小食心虫的虫梢数从5月中旬开始迅速增加,6月下旬达到峰值,之后逐渐下降。比较得出抗蚜地块中的梨小食心虫虫害发生时间早于对照地块(图5)。

3 讨 论

昆虫是种类最多、数量最大的动物类群,开展作物田间昆虫群落研究是农业害虫防治的基础[36-37]。已知,抗虫品种的推广应用会对作物田间昆虫群落产生影响。例如,通过回顾转基因BT抗虫棉的应用历史,转基因BT抗虫棉应用多年后,棉田间主要害虫(棉铃虫)虽然得到了很好的控制,但一些次要害虫的数量可能会大幅增加并成为主要害虫[24,38]。笔者课题组前期针对寿星桃类桃树抗蚜材料的抗性鉴定表明,寿星桃抗蚜材料对桃蚜具有强烈的趋避性抗性[11,39],抗蚜品种种植后能够控制桃蚜的危害。本研究对抗蚜地块和对照地块内的昆虫群落组成和昆虫群落个体数量的动态变化分析显示,综合全生长期数据,抗蚜地块内的昆虫个体总数大于对照地块;抗蚜地块前期(3 月下旬至6 月下旬)诱集到的昆虫总数大于对照地块,而这之后的昆虫数目基本一致,前期抗蚜地块昆虫总数升高可能是减少了桃蚜控制所使用的农药导致的。

抗虫作物如转基因抗虫作物在长期种植过程中对非靶标害虫的影响及防控研究已经成为各国科学家关注的焦点[25]。例如,在转基因抗虫棉田中,靶标害虫的有效控制使杀虫剂在Bt 转基因抗虫棉田中的使用模式发生了改变,从而导致多种害虫的种群地位和生态位空间出现了演替变化[40]。转基因Bt抗虫棉种植后,用于防治靶标害虫(棉铃虫)的化学农药使用次数减少到5 次[41]。然而,由于非靶标害虫(如蚜虫、叶蝉、盲蝽)数量的显著增加,用于防治非靶标害虫的化学农药的剂量比原来增加了接近一倍,因此,根据非靶标害虫的发生规律采取相应的防治措施对防治Bt 抗虫棉田间害虫非常必要。本研究中桃树非靶标害虫,如梨小食心虫也是桃栽培生产过程中的主要防治对象,相比对照地块,梨小食心虫在抗蚜地块内的发生时间提前,如不及时防治,将对桃树造成严重的危害。因此,笔者建议,在抗蚜品种应用过程中,更应该加强对梨小食心虫、苹小卷叶蛾、红蜘蛛和橘小食蝇等除桃蚜外桃树主要害虫的监测工作,了解这些桃树主要害虫的发生情况,科学适时开展针对性的防治工作,以避免对桃园造成的潜在危害。本试验开展对抗蚜地块中昆虫群落的种类和数量的研究,为将来抗蚜品种应用推广配套植保措施的制定提供了数据基础。

转基因抗虫作物的种植可以通过减少害虫数量而降低天敌种群数量,而转基因作物田间杀虫剂使用量的减少,又有利于天敌种群的增加[42]。本研究中,抗蚜地块和对照地块中昆虫群落个体总数随时间变化的整体趋势是一致的,但抗蚜地块昆虫总数出现了增加的现象,其中害虫总数和益虫总数同步增加,两地块之间益害虫比没有明显差异。但这并不是最终的结果,随着抗蚜品种应用时间变长,上一年度田间昆虫通过冬季休眠后会对次年田间昆虫群落造成影响。前人也有研究发现,次要害虫种群会在适宜的条件下逐渐发展成为田间的主要害虫,并导致次要害虫大暴发,这个过程需要持续很长时间才会出现,只有通过长期研究才能有效地评估和监测所有的潜在影响[43-44]。目前,本研究仅对桃树抗蚜品种短期应用后的昆虫群落结构特征进行了为期一年的调查与分析,试验周期短,桃树主要害虫的种群增长已经表现出提前的趋势,虽然部分变化确实并不非常显著,但仍值得笔者长期关注。因此,未来还需要开展更多针对抗蚜品种田间昆虫群落中昆虫种类和数量变化影响的长期研究工作。

4 结 论

综合本研究,发现抗蚜品种短期应用后,田间昆虫种类和昆虫总数的周年变化规律未发生较大变化,但抗蚜地块昆虫总数明显多于对照地块。与对照地块比较,抗蚜地块中的优势昆虫种群(双翅目、半翅目、鳞翅目和膜翅目)的昆虫总数存在发生高峰提前和总数增加的趋势。抗蚜地块中的多数中性昆虫和天敌昆虫的数量也存在发生高峰提前和总数增加的趋势。两地块益、害虫比无明显差异。笔者对抗蚜地块中昆虫群落的种类和数量进行了研究,为将来抗蚜品种应用推广配套植保措施的制定提供了有益参考。

Abstract:【Objective】The purpose of this study was to find out the changes of insect community structure in the field growing aphid-resistant varieties of peach tree by using the method of insect mathematical ecology,so as to explore the effects of the aphid-resistant varieties on the species and numbers of insects caused by non-target insects.It would provide a reference for the plant protection cultivation measures adopted when the aphid-resistant varieties come into use in the future.【Methods】The aphid-resistant varieties and control varieties were used in the experiment in the Xinxiang Comprehensive Experimental Base of Zhengzhou Fruit Research Institute, Chinese Academy of Agricultural Sciences , In the case of using the aphid-resistant variety,aphid control was not applied in the early spring.The dynamic changes of insect community composition and number of insect community individuals in the plots using the aphid-resistant variety and control variety were analyzed by Malay net collection method,insect sex pheromone trapping method and visual survey method.【Results】A total of 5955 insects samples were collected in the plot using aphid-resistant variety and they belonged to 9 orders. They were Diptera, Hemiptera, Lepidoptera, Hymenoptera, Arachnoidea, Neuroptera, Coleoptera, Orthoptera, and Thysanoptera.A total of 4606 insect samples were collected in the CK plot and they belonged to 8 orders.They were Diptera,Hemiptera,Lepidoptera,Hymenoptera,Arachnoidea,Neuroptera,Coleoptera and Orthoptera.The total number of insects collected in the plot using aphid-resistant variety was greater than those in the CK plot,and there was no significant difference in the percentage of insects of each order in the two plots. The pests in the plot using the aphid-resistant variety accounted for 40.70% of the total number of the insects and 35.93% in the control plot.The pests included Lepidoptera, Hemiptera and Arachnoidea. The beneficial insects in the plot using the aphid-resistant variety accounted for 15.95%of the total number of the insects and 12.26%in the control plot.The beneficial insects included Syrphidae,Coccinellidae and lacewing.The other insects were neutral insects,mainly including Diptera, Coleoptera, Orthoptera and Thysanoptera, they accounted for 43.36% of the total number of the insects in the plot using the aphid-resistant,and 51.81%in the CK plot.The benefit/pest ratio of the plot using the aphid-resistant variety and and of the control plot were not significantly different in terms of the overall trend. The total number of insects collected in the the plot using the aphid-resistant variety was greater than those in the CK plot,and the total number of insects in the early stage of the plot using the aphid-resistant(late March to early June)was greater than those in the control plot,and the number was basically the same in the later stage. The trend of the total number of insects in the plot using the aphid-resistant variety and in the control plot was basically consistent with time.Compared with the CK plot, the total number of insects in the dominant insect populations (Diptera, Hemiptera, Lepidoptera and Hymenoptera) in the plot using the aphid-resistant variety had a tendency to peak earlier and increase the total number during the pest occurrence season.The number of most neutral insects and natural enemy insects in the plot using the aphid-resistant variety also tended to peak earlier and increase total number.【Conclusion】Using the aphid-resistant variety in the orchard could possibly increase the total number of insect individuals due to the lack of the use of the pesticide to peach aphids in the early spring
