New Evidence for the Hypothesis of Reducing Natural Enemy Pressure of Eupatorium adenophorum: Solenopsis invicta Competing with Doxrylus orientalis to Feed on E. adenophorum

Natural enemy insects are important factors in regulating plant invasion. The interactions between multiple insect species resulting from invasive plants remain poorly understood despite their potential. We observed notorious invasive plants Eupatorium adenophorum Sprengel were competedly fed by Solenopsis invicta Buren (Hymenoptera: Formicidae) and Dorylus orientalis Westwood (Hymenoptera: Formicidae) beside the scientific research base of Kunming University. It was first observed that D. orientalis was eating the epidermis, cortex, phloem and other root and stem tissues of E. adenophorum in soil. Two months later, it was observed that S. invicta ate the epidermis, cortex, phloem and other aboveground stem tissues of E. adenophorum. S. invicta attacked D. orientalis and displaced their living space by causing the later dead, injured, or even disabled. This phenomenon suggested that local herbivorous insects have adapted to E. adenophorum well, which will intensify the naturalization process of E. adenophorum in local habitats. In a homogeneous garden planting experiment of E. adenophorum conducted at the experimental base of Kunming University, the biomass of the introduced (China) populations of E. adenophorum was lower than that of the native (Mexico) populations, although there was no statistically significant difference. These results indicate a possible positive correlation between the increase in natural enemy pressure and the decrease in fitness of E. adenophorum.

A Mechanism for Biological Control-Tempo-Spatial Synchronization of Natural Enemy and Insect Pest Population Dynamics at the Peak by Increase of Biodiversity

To reveal the mechanism of control of the Woolly Apple Aphid （Eriosoma lanigerum Hausm, WAA） by increase of biodiversity in the apple orchard, a consecutive two-year field trials were conducted in Yurman province, China. The results showed that the peak of natural enemy density curve in the cover cropping orchard was well temporally synchronized with that of the WAA density on trees, but did not synchronize with that of WAA density on trees in clean orchard. In addition, the frequency of natural enemies and WAA within a same sample in cover cropping orchard was obviously higher than that in clean cultivated orchard during the peak of population curves, indicating that natural enemies spatially synchronized with aphids. The density of WAA for the whole growing season in cover cropping orchard was much less than that in clean orchard. Therefore, the temporal-spatial synchrony of natural enemy and aphid populations was proposed as one of the mechanisms for aphid control in cover cropped orchards.

Comparative Efficacies of Next-Generation Insecticides Against Yellow Stem Borer and Their Effects on Natural Enemies in Rice Ecosystem

The efficacies of some next-generation insecticides against the rice yellow stem borer(YSB),Scirpophaga incertulas(Walk.), and their compatibilities with natural enemies were investigated during 2014 and 2015. Three newer insecticides, chlorantraniliprole 0.4% G, dinotefuran 20% SG, and methoxyfenozide 24% SC, and two commonly used insecticides, carbufuran 5 G and quinalphos 25 EC,were evaluated in the field for their efficacies against YSB and their non-target effects on natural enemies.Application of chlorantraniliprole 0.4% G at 10.96 kg/hm^2 resulted in the greatest reduction in YSB infestation(deadhearts and whiteheads) and greatest increase of yield compared to the untreated control plots, followed by methoxyfenozide 24% SC at 0.41 L/hm^2, dinotefuran 20% SG at 0.15 kg/hm^2,carbufuran 5 G at 10.96 kg/hm^2, and quinalphos 25 EC at 1.50 L/hm^2. All the insecticides reduced the numbers of predators viz., lady bird beetles, wolf spiders, carabid beetles, earwigs, green mirid bugs, and damselflies. Numbers of adults of the egg parasitoids Trichogramma sp., Telenomus sp. and Tetrastichus sp. were significantly reduced in insecticide-treated plots compared to untreated control plots. In all field trials, the harmful effects of the five insecticides were in the following rank order(least harmful to most harmful): chlorantraniliprole 0.4% G, carbufuran 5 G, dinotefuran 20% SG, methoxyfenozide 24% SC,and quinalphos 25 EC. On the basis of reduction in YSB infestation, increase in grain yield, and compatibility with natural enemies, chlorantraniliprole 0.4% G was proved to be the best of all the insecticides for YSB management system, although the study suggested minimizing its retail price for enhancement of cost effectiveness in farmers' fields.

Natural Enemies of Calidea panaethiopica (Heteroptera: Scutelleridae): An Insect Pest of Jatropha curcas L. in the South-Sudanian Zone of Burkina Faso

Jatropha curcas L. is a non-edible oleaginous plant of Euphorbiacea family. Its seeds provide oil for industrial use, and when grown as a biofuel, J. curcas can be used to restore degraded soil by improving their fertility and by controlling water and wind erosion. The plant also reduces CO2 emission by carbon sequestration. However, J. curcas is attacked by many insect pests including C. panaethiopica, a polyphagous heteroptera of the Scutelleridae family. Larvae and adults of the insect pest feed on J. curcas flowers, fruit, and seeds, thereby causing quantitative and qualitative losses. Despite the economic importance of this insect pest, there is little known about its potential natural enemies. A survey of the natural enemies of C. panaethiopica was carried out from 3rd June 2013 to 29th May 2014 on three J. curcas production sites in the South-Sudanian zone of Burkina Faso. Three Hymenopteran egg parasitoids all belonging to the Scelionidae family were found. These included Trissolcus basalis (Wollaston), Psixstriaticeps (Dodd), and Gryon sp. Several predator species belonging to the Araneae, Tarachodidae and Mantidae families were also found. The egg parasitism increased progressively between June and September 2013, reaching a peak (43%) in September 2013. The number of spiders and mantises was higher between July and August 2013. The highest numbers of natural enemies associated with the insect pest were recorded in J. curcas monoculture plantations.

Diversity of insect communities with different development phases in natural Populus euphratica forests in Xinjiang

An investigation method with sample plots was used to study insect communities in four different growth phases of natural Populus euphratica forests, which are juvenile, middle aged, over-mature and degraded forests, in Tarim, Xinjiang in July, 2005 and April, 2006. In our studies, 5,116 insect specimens, belonging to 12 orders, 61 families and 141 species, were collected. Lepidoptera and Coleoptera were the dominant orders. In middle-aged forests, species, individual numbers and diversity indices of insect com-munities were higher than those in other woodlands. The species richness and diversity indices were lowest in degraded forests be-cause of extremely scarce vegetation.

蜾蠃亚科物种的筑巢生物学研究现状

蜾蠃(Eumeninae)是胡蜂科(Vespidae)中种类最丰富的一个亚科,已知204属3800种,分布广泛、筑巢策略多样,其生活方式从绝大多数独居到极少数种类的原始社会性,对研究社会性昆虫演化具有重要价值。繁殖期筑巢是蜾蠃亚科物种生活史的重要阶段,也是子代繁殖成功的重要保障。按照其筑巢习性传统上可将蜾蠃亚科物种分为挖掘型、租住型和建造型3种类型。然而,蜾蠃亚科物种的筑巢在同种雌性中也具有很强的可塑性和建造不同类型的巢的习性。不论采用何种筑巢类型,蜾蠃亚科常用泥筑巢,也有一些种类用嚼碎的叶子或碎石子筑巢,甚至有少数种类会用植物材料或鸟粪等伪装巢。食物供应是蜾蠃筑巢过程中最大的精力和时间投资。大多数独居的蜾蠃是截断式为子代巢室内供应食物(将瘫痪的昆虫猎物作为幼虫的食物),一些具有原始社会行为的蜾蠃是渐进式供应,尤其是在猎物稀缺的情况下表现更明显。蜾蠃亚科主要捕猎鳞翅目(Lepidoptera)[尺蛾科(Geometridae)和卷蛾科(Tortricidae)]和鞘翅目(Coleoptera)[叶甲科(Chrysomelidae)和象鼻甲科(Curculionidae)]科幼虫,在农业重要鳞翅目和鞘翅目害虫的生物防治中具有重要作用。尽管蜾蠃亚科如此重要,但其筑巢生物学仍然鲜为人知,我国有关蜾蠃亚科物种的筑巢生物学研究更少。因此,本文系统综述了目前蜾蠃亚科筑巢生物学的研究现状,并提出未来研究建议如下:(1)研究蜾蠃亚科物种在不同生境中的筑巢生物学特点;(2)研究植物-植食性害虫-蜾蠃-天敌昆虫之间的食物网关系,进而揭示不同蜾蠃在农业和自然生态系统的功能;(3)优势蜾蠃在害虫生态防控中的应用研究。

美国白蛾天敌昆虫应用研究进展

美国白蛾是一种国际检疫性害虫,原产于北美。由于美国白蛾强大的扩散能力、较长的为害期以及快速繁殖等特性,目前已有35个国家报道了其入侵记录。自1979年美国白蛾在辽宁丹东发现以来,不断地向我国南方地区扩散。因此,根除全部种群已不可能,采取持续有效的生物防控策略是可行的途径。本文总结了国内外美国白蛾的捕食性和寄生性天敌种类,比较了不同地区和不同发生期美国白蛾天敌的多样性,并对利用本地天敌和引进原产地天敌防治美国白蛾的应用技术进行了归纳分析。原产地天敌对美国白蛾具有更强的适应性和攻击性,通过引进原产地天敌可望实现更加持续有效的控制作用。最后展望了天敌昆虫控制美国白蛾的应用前景。

四种功能植物对花生田捕食性天敌昆虫与蓟马的影响

为明确不同功能植物对花生田主要捕食性天敌和蓟马发生的影响,本研究在花生田种植了四种功能植物,设计为三组处理区(婆婆纳+接力植物菊芋处理区、百日菊处理区、菊苣处理区),构建花生-功能植物微景观系统,调查分析了不同处理区瓢虫科、花蝽科和食蚜蝇科三类捕食性天敌和蓟马的种群发生量和发生动态。结果表明:婆婆纳+接力植物菊芋处理区食蚜蝇发生总量显著高于花生单作,为1.85倍;苗期食蚜蝇大量发生时婆婆纳对食蚜蝇的吸引作用显著。这一组合中的接力植物菊芋在7月下旬至8月初对瓢虫科的引诱效果显著高于百日菊、菊苣和花生单作。百日菊处理区从7月中旬至8月下旬食蚜蝇科天敌发生量显著高于菊苣区、婆婆纳+菊芋区和花生单作区,而且其瓢虫科和花蝽科的总量也显著高于花生单作区,分别为花生单作区的2.44倍和3.02倍。菊苣处理区瓢虫科的总量是花生单作的3.35倍。此外,种植三组功能植物后,花生斑块的蓟马类害虫发生总量没有显著性下降,但三组处理区的花蓟马的发生量均显著低于花生单作区,婆婆纳+菊芋处理区和百日菊处理区花生斑块上早期发生的玉米黄呆蓟马的发生量显著低于花生单作区。本研究表明,婆婆纳对食蚜蝇科、菊苣和菊芋对瓢虫科、百日菊对三类天敌有显著的引诱效果,三组功能植物虽然不能压低花生上蓟马类害虫总体的种群数量,但对花生田优势蓟马花蓟马有一定控制作用;婆婆纳+菊芋和百日菊对花生上的玉米黄呆蓟马有一定控制作用,对于苗期花生蓟马控害有积极意义。

基于捕食性天敌资源的番茄潜叶蛾生物防控研究进展

番茄潜叶蛾是一种世界范围的重大外来入侵物种,主要通过幼虫潜叶和蛀果危害番茄作物。自2017年入侵新疆伊犁以来,该虫已扩散蔓延至我国多个省份(直辖市和自治区),并在多地暴发成灾,严重威胁我国番茄产业的生产。基于捕食性天敌资源的生物防治是当前番茄潜叶蛾综合治理的主要手段之一。目前,关于番茄潜叶蛾捕食性天敌资源研究现状的综述性论文较少。据此,本文系统梳理了全球范围内的番茄潜叶蛾捕食性天敌资源种类,概括了捕食性天敌对番茄潜叶蛾的捕食能力、取食番茄潜叶蛾后捕食性天敌的生命参数、化学农药对捕食性天敌防控番茄潜叶蛾的影响,分析了当前利用捕食性天敌防治番茄潜叶蛾存在的问题和发展方向,以求为我国番茄潜叶蛾生物防治工作提供参考。
