The parasitoids Pachycrepoideus vindemmiae Rondani (Hymenoptera: Pteromalidae) and Trichopria anastrephae Costa Lima (Hymenoptera: Diapriidae) have great potential in controlling Drosophila suzukii (Matsumura); however, both, compete for the same resources. In this study, we evaluated whether the different stages of development of the primary parasitoid reduce the negative effect of intrinsic competition. For this, we first defined the duration of each immature stage of both parasitoid species and then offered D. suzukii pupae containing the first parasitoid (P. vindemmiae or T. anastrephae) at different stages of development to the second parasitoid (P. vindemmiae or T. anastrephae). We also checked the second parasitoid's preference (P. vindemmiae or T. anastrephae) for the primary parasitoid at different stages of development (P. vindemmiae or T. anastrephae) or D. suzukii pupae nonparasitized. Our evaluations showed that T. anastrephae preferred to parasitize pupae that were not previously parasitized and that had not parasitized puparia of D. suzukii when P. vindemmiae was in later stage to the 1st instar. However, P. vindemmiae preferred to parasitize pupae previously parasitized by T. anastrephae. In an environment of intrinsic competition, the first parasitoid to parasitize has an advantage, except when the pupal stage of T. anastrephae is parasitized by P. vindemmiae. The variation in the parasitoids' oviposition time mitigates the competition effect; however, for use in biological control programs, the hyperparasitoids P. vindemmiae, does not prove to be advantageous, as they can affect the establishment of primary parasitoids such as T. anastrephae, and can act as competitors for resources.
寄主寄生蜂(膜翅目:姬蜂科)和寄生蜂(膜翅目:姬蜂科)对苏氏果蝇有较大的防治潜力;然而,两者都在争夺同样的资源。在本研究中,我们评估了初级寄生蜂的不同发育阶段是否会减少内在竞争的负面影响。为此,我们首先确定了两种寄生蜂各未成熟阶段的持续时间,然后将含有不同发育阶段的第一寄生蜂(vindemiae或T. anastphae)的铃木氏夜蛾蛹提供给第二寄生蜂(vindemiae或T. anastphae)。在不同的发育阶段,我们还比较了第二寄生蜂对第一寄生蜂和未被寄生的铃木氏夜蛾蛹的偏好。研究结果表明,在幼虫发育后期至1龄阶段,猪夜蛾更倾向于寄生未寄生和未寄生过猪夜蛾蛹的幼虫。然而,青肠粉蚧更倾向于寄生于已被青肠粉蚧寄生的蛹。在内在竞争的环境中,除灰瓢虫蛹期被灰瓢虫寄生外,第一个寄生的寄生蜂具有优势。寄生蜂产卵时间的变化减轻了竞争效应;然而,在生物防治中,高寄生性的vindemiae并不具有优势,因为它们会影响原生寄生性的建立,如灰鳞绦虫,并可能成为资源的竞争对手。

Scaling up syntheses from mg to kg quantities is a complex endeavor. Besides adapting laboratory protocols to industrial processes and equipment and thorough safety assessments, much attention is paid to the reduction of the process' environmental impact. For processes including transition metal catalyzed steps, e.g. cross-coupling chemistry, this impact strongly depends on the identity of the metal used. As such, a key approach is the replacement of single-use with reusable heterogeneous catalysts. Transition metal single-atom heterogeneous catalysts (SAC), a novel class of catalytic materials, might exhibit all the necessary properties to step up to this task. This article shall discuss current applications of SAC in cross-coupling chemistry from the point of a process chemist and shed light on the NCCR Catalysis contribution to the field. Investigations of the stability-activity-selectivity relationship of SACs in combination with early-stage life-cycle assessments (LCA) of potential processes lay the foundation for large-scale application tailored catalyst synthesis. Ultimately, prevailing challenges are highlighted, which need to be addressed in future research.

将合成量从毫克增加到公斤是一项复杂的工作。除了使实验室协议适应工业过程和设备以及彻底的安全评估外,还非常重视减少过程对环境的影响。对于包括过渡金属催化步骤在内的工艺,例如交叉偶联化学,这种影响很大程度上取决于所使用金属的特性。因此,一个关键的方法是用可重复使用的多相催化剂取代一次性催化剂。过渡金属单原子非均相催化剂(SAC)是一类新型的催化材料,它可能表现出完成这一任务所需的所有特性。本文将从过程化学家的角度讨论SAC在交叉偶联化学中的当前应用,并阐明NCCR催化对该领域的贡献。研究sac的稳定性-活性-选择性关系,结合潜在工艺的早期生命周期评估(LCA),为大规模应用定制催化剂合成奠定了基础。最后,强调了当前面临的挑战,这些挑战需要在未来的研究中加以解决。

Abstract The nutritional quality of herbivorous insects' food can not only directly affect the herbivorous insects themselves, but can also indirectly affect their parasitoids. To investigate these cascading, multi-trophic effects, we reared cabbage looper, Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae), on artificial diets (8.1, 11.5, 16.75, 25.5, 34.25, and 43 g protein/liter diet) to assess how diet protein content affected the development of this common pest and its suitability as a host for the gregarious parasitoid, Cotesia vanessae (Reinhard) (Hymenoptera: Braconidae). Nonparasitized caterpillars experienced increased mortality when reared on 8.1 g protein/liter diet, and slower development and reduced pupal mass when reared on ≤16.75 g protein/liter diet. Host diet did not affect the percentage of hosts with parasitoid emergence nor the mass of individual parasitoids. However, parasitoid broods emerging from caterpillars reared on ≤25.5 g protein/liter diet were smaller and those reared on ≤16.75 g protein/liter diet exhibited prolonged development. The consequences of host diet on these latter F1 parasitoids did not affect their reproductive fitness. Caterpillars compensated for nutrient stress, induced by either low quality diet or parasitism, by increasing the amount of diet that they consumed. These collective results demonstrate the plasticity of host-parasitoid systems. Compensatory feeding allows the host caterpillar to moderate the consequences of low quality diets, which may subsequently affect the F1 parasitoids developing within the host, but not necessarily affect the F2 parasitoid generation.

Le taux de protéines dans l'alimentation des chenilles n'a pas influencé le pourcentage de chenilles parasitées qui ont produits des parasitoïdes, ni la masse individuelle des parasitoïdes.

摘要:食草动物食物的营养质量不仅直接影响食草动物本身,还可能间接影响其寄生生物。为了研究这些级联的多营养效应,我们在人工饮食(8.1、11.5、16.75、25.5、34.25和43克蛋白质/升饮食)上阅读了卷心菜环、Trichoplusia ni(Hübner)(鳞翅目:夜蛾科),以评估饮食蛋白含量如何影响这种常见害虫的发展及其作为希腊寄生虫Cotesia vanessae(Reinhard)(膜翅目:短翅目)宿主的适用性。非寄生毛毛虫在食用8.1克蛋白质/升饮食时死亡率增加,食用≤16.75克蛋白质/公升饮食时发育缓慢,蛹质量减少。宿主饮食不影响寄生虫出现的宿主百分比或个体寄生虫的数量。然而,从食用≤25.5克蛋白质/升饮食的毛毛虫中出现的寄生虫血较小,食用≤16.75克蛋白质/公升饮食的寄生虫血发育延长。宿主饮食对这些晚期F1寄生虫的影响并不影响其生殖健康。卡特彼勒通过增加他们消耗的饮食量来补偿由低质量饮食或寄生引起的营养压力。这些集体结果证明了宿主寄生系统的可塑性。代偿喂养允许宿主毛毛虫减少低质量饮食的后果,这可能随后影响宿主内发育的F1寄生虫,但不一定影响F2寄生虫的产生。摘要:食草动物食物的营养质量不仅会直接影响食草动物,还会间接影响食草动物寄生虫。为了研究这些多营养效应,我们在人工营养培养基(8.1、11.5、16.75、25.5、34.25和43 g/L蛋白质)上饲养了卷心菜假测量员Trichoplusia ni(Hübner)(鳞翅目:夜蛾科)的幼虫,以评估营养培养基的蛋白质水平如何影响这种常见害虫的发育及其作为群居寄生蜂Cotesia vanessae(Reinhard)(膜翅目:短翅目)宿主的质量。对于非寄生幼虫,在每升含8.1g蛋白质的营养培养基上饲养的幼虫死亡率增加,在每公升含16.75g蛋白质或更少的营养培养基中饲养的幼虫发育时间增加,蛹质量减少。毛毛虫饲料中的蛋白质水平不影响产生寄生虫的寄生毛毛虫的百分比或寄生虫的个体质量。然而,在每升蛋白质含量不超过25.5g的营养培养基上饲养的寄生毛毛虫每只毛毛虫产生的寄生虫较少,而在每升蛋白质含量不超过16.75g的营养培养基中饲养的寄生虫产生的寄生虫生长更慢。在第二代寄生虫中未检测到毛毛虫饲料中蛋白质水平的影响。毛毛虫通过增加食物消耗量来补偿饮食中蛋白质水平低或寄生虫引起的营养压力。这些结果证明了宿主/寄生虫系统的可塑性。通过调整食物摄入量,毛毛虫能够减轻低蛋白营养环境的负面影响,这些影响可能会影响毛毛虫体内寄生虫的发育,但不一定会影响下一代寄生虫。

Abstract Invertebrates that successfully colonize new habitats often share life history characteristics including high fertility, rapid development, and early maturation. Since its introduction into Florida, USA, the non-native Brown Widow, Latrodectus geometricus (Kock 1841, Araneae: Theridiidae), has rapidly expanded its range into urban areas as far north as Kansas and as far west as California. During its expansion, the Brown Widow has displaced Florida's Southern Black Widow, L. mactans (Fabricius 1775, Araneae: Tjerodoodae) and California's Western Black Widow, L. Hesperus (Chamber lin & Ivie 1935, Araneae: Theridiidae). Here, based on a field survey and controlled laboratory experiments, we report possible causes for the rapid disappearance of Florida's Southern Black Widows. Our field survey revealed that Brown Widows have twice the fertility potential as Southern Black Widows. In experiments comparing development, we show that sub-adult Brown Widows grew faster and matured earlier relative to Southern Black Widows. In our experiments on cohabitation with neighbors, bold Brown Widows were six times more likely to kill and consume shy Southern Black Widows than bold cobweb spiders and three times more likely to cohabitate with bold cobweb spiders than with shy Southern Black Widows. Our model of maternal risk-management revealed that competition for scarce prey was not a significant cause of offspring mortality for Latrodectus species. Hence, Brown Widows are not predating Black Widows or other cobweb spiders because prey is scarce. To our knowledge, this study is the first to suggest that aggressive predation by Brown Widows is a significant factor contributing to the local extinction of the shy Southern Black Widow in urban structures.
成功殖民新栖息地的无脊椎动物通常具有高繁殖力、快速发育和早熟的生活史特征。自从它被引入美国佛罗里达州以来,非本地的棕寡妇,棕寡妇(Kock 1841,蜘蛛目:棕寡妇科)迅速扩大了它的活动范围,北至堪萨斯州,西至加利福尼亚州。在其扩张过程中,褐寡妇取代了佛罗里达州的南部黑寡妇,L. mactans (Fabricius 1775,蜘蛛目:蜘蛛科)和加利福尼亚州的西部黑寡妇,L. Hesperus (Chamber lin & Ivie 1935,蜘蛛目:蜘蛛科)。在这里,基于实地调查和受控的实验室实验,我们报告了佛罗里达州南部黑寡妇迅速消失的可能原因。我们的实地调查显示,褐寡妇的生育潜力是南方黑寡妇的两倍。在比较发育的实验中,我们发现相对于南方黑寡妇,亚成年褐寡妇生长更快,成熟更早。在我们与邻居同居的实验中,大胆的棕色寡妇杀死和吃掉害羞的南方黑寡妇的可能性是大胆的蜘蛛网蜘蛛的六倍,与大胆的蜘蛛网蜘蛛同居的可能性是与害羞的南方黑寡妇同居的三倍。我们的母系风险管理模型显示,对稀少猎物的竞争并不是疟蚊后代死亡的重要原因。因此,棕寡妇蜘蛛并不比黑寡妇蜘蛛或其他蜘蛛网蜘蛛早,因为猎物很少。据我们所知,这项研究首次表明,棕色寡妇的侵略性捕食是导致城市结构中害羞的南方黑寡妇局部灭绝的重要因素。

Abstract Using seventeen-year records of daily light trap catches of predatory Neuroptera (Chrysopidae, 13 species) and Coleoptera (Coccinellidae, 10 species), and of phytophagous Lepidoptera (Noctuidae, 79 species) we tested a hypothesis predicting that the range of annual fluctuations of catch size is greater in aphidophages, whose diet occurs irregularly and locally, than in phytophages, whose diet is available regularly and abundantly.The ranges of fluctuations of annual catches measured as the coefficient of variance (standard deviation expressed as a percentage of the average) of detrended annual catches were significantly greater in Chrysopidae (84 ± 7.1%) and Coccinellidae (121 ± 14.0%) than in Noctuidae (66 ± 2.6%). The difference between aphidophages and phytophages remained when we tested differences between the former and the samples of Noctuidae consisting only of those species whose characteristics (abundance, length and timing of flight period, number of generations per season, overwintering stage) were the same as in aphidophages. Similarly, no differences were found between sets of Noctuidae species that have characteristics (abundance, voltinism, period of flight activity) similar to aphidophages and sets of Noctuidae species that have contrary characteristics. Flight abilities of aphidophages are smaller than those of Noctuidae. As a result of this difference a light trap collects populations of aphidophages from a smaller area than populations of Noctuidae.Thus the extent of fluctuations of catch size of aphidophagous and phytophagous species is influenced both by annual differences in food availability and by differences in size of the area from which the individuals assembling to the light source are recruited.
摘要利用捕食性神经翅目(金蝇科,13种)和鞘翅目(球虫科,10种)以及植食性鳞翅目(夜蛾科,79种)17年来的每日光捕记录,我们检验了一个假设,即食饵不规则且局部发生的食蚜蝇的年捕获量波动幅度大于植食性,其饮食规律且丰富。以去趋势年渔获量的方差系数(以平均值的百分比表示的标准差)来衡量的年渔获量的波动范围,金蝇科(84±7.1%)和球虫科(121±14.0%)明显大于夜蛾科(66±2.6%)前者和仅由那些特征(丰度、飞行期的长度和时间、每个季节的世代数、越冬阶段)与食蚜蝇相同的物种组成的夜蛾科样本。同样,在具有类似于食蚜蝇的特征(丰度、电压性、飞行活动期)的夜蛾科物种组和具有相反特征的夜蛾科物种组之间也没有发现差异。食蚜蝇的飞行能力比夜蛾科的小。由于这种差异,光阱从比夜蛾科更小的区域收集食蚜种群。因此,食蚜和植食性物种的捕获量波动程度受到食物供应的年度差异和收集聚集到光源的个体的区域大小差异的影响。

Abstract This review summarizes which body parts have taste function in which insect taxa. Evidence of taste by mouthparts, antennae, and tarsi is widespread. Mouthparts that commonly have taste function are the labium, including the labella and labial palps, the maxillae, including the galeae and maxillary palps, the inner surface of the labrum or clypeolabrum of chewers, and inside the precibarium/cibarium of hemipterans, which have piercing-sucking mouthparts. Tasting with mandibles has not been found, and tasting with the hypopharynx is seldom reported. Use of the antennae appears uncommon among fly species, but common among species of lepidopterans, hymenopterans, beetles, and bugs. Although tasting with legs, especially tarsi, is reported mostly for fly and lepidopteran species, there is also evidence of it for multiple species of beetles, grasshoppers, and hemipterans, and one species of a roach, an ant, and a bee. Ovipositor taste function has been supported for some species of flies, lepidopterans, hymenopterans, orthopterans, and odonates. Taste by wings has been much less studied, but has been documented in a few fly species. Taste remains unstudied for any species or any body parts of Archaeognatha, Dermaptera, Mantodea, Mecoptera, Phasmatodea, Megaloptera, Neuroptera, Phthiraptera, Psocoptera, Siphonaptera, as well as Raphidioptera, Strepsiptera, Embioptera, Notoptera, and Zoraptera. Across holometabolous insects, larvae have not often been examined, the exception being some species of lepidopterans, flies, and beetles. Taste studies of antenna and legs are uncommon for even lepidopteran and beetle larvae.
摘要本文综述了哪些昆虫类群中哪些身体部位具有味觉功能。口器、触角和跗骨的味觉证据非常普遍。通常具有味觉功能的口腔是上唇,包括唇瓣和唇须,上颌骨,包括唇盖和上颚须,咀嚼者的上唇或唇腭裂的内表面,以及半翼龙的唇腭裂/唇腭裂内部,它们有尖锐的吮吸口器。用下颚品尝的情况尚未发现,用下咽品尝的情况也很少报道。触角的使用在苍蝇中并不常见,但在鳞翅目、膜翅目、甲虫和昆虫中很常见。尽管用腿品尝,尤其是用跗骨品尝,主要是针对苍蝇和鳞翅目物种,但也有证据表明,多种甲虫、蚱蜢和半翅目昆虫,以及一种蟑螂、蚂蚁和蜜蜂都有这种味道。某些种类的苍蝇、鳞翅目昆虫、膜翅目昆虫、直翅目昆虫和齿形类动物的味觉功能得到了支持。对翅膀味道的研究要少得多,但在一些苍蝇物种中已经有记录。对于任何物种或任何身体部位的古颌目、Dermaptera、Mantodea、Mecopera、Phasmatodea、Megaloptera、Neuroptera、Phthiraptera、Psocoptera、Siphonaptera,以及Raphidiptera、Strepsiptera、Embioptera、Notoptera和Zoraptera,味道仍然没有研究。在全代谢组昆虫中,幼虫并不经常被检查,只有一些种类的鳞翅目昆虫、苍蝇和甲虫除外。即使是鳞翅目和甲虫幼虫,对触角和腿的味觉研究也不常见。
