光眉刺蛾的线粒体基因组研究及系统发育分析

为探究光眉刺蛾Narosa fulgens(Leech,1889)的线粒体基因组结构及刺蛾科的系统发育关系,利用下一代测序方法获得光眉刺蛾线粒体全基因组序列。系统发育分析中使用斑蛾总科16个物种作为内群,并选择木蠹蛾科和网蛾科各1个物种作为外群,利用最大似然法和贝叶斯法重建刺蛾科的系统发育关系。光眉刺蛾的线粒体基因组包含37个基因(13个蛋白质编码基因、22个转运RNA基因和2个核糖体RNA基因)和1个非编码控制区,全长为15296 bp(GenBank登录号:OP919326)。光眉刺蛾线粒体基因组的13个蛋白质编码基因的起始密码子除cox1利用CGA开头外,其余蛋白质编码基因都是以ATN开头,终止密码子除cox2和nad4以不完整的T结尾外,其余蛋白质编码基因都是以TAA和TAG结尾。除trnS1因缺少DHU臂而形成一个简单的环,无法形成稳定的三叶草结构外,其余转运RNA基因均能形成典型的三叶草结构。rrnL的全长为1335 bp,A+T含量为85.24%。rrnS的全长为732 bp,A+T含量为84.70%。两个方法构建的系统发育树的结果均表明:斑蛾科和刺蛾科为单系群,光眉刺蛾与龟形小刺蛾Narosa nigrisigna为姐妹群。

鳞翅目昆虫声音通讯作用与机制

昆虫与地球上其他动物一样存在声音通讯,声音通讯在昆虫种间或种内交流、防御天敌和求偶等方面起着重要的作用。在长期的天敌捕食压力下,鳞翅目昆虫进化出发声器官和听觉器官进行声音通讯,以此减少被捕食的风险。本文对鳞翅目昆虫的声音通讯作用、发声器官和听觉器官结构、发声方式等进行综述,并展望利用声波防治鳞翅目害虫的潜力,为鳞翅目昆虫声音通讯的深入研究提供参考,也为该类害虫的绿色防控提供思路。

新宾县鳞翅目蛾类昆虫资源变化及年际动态分析

为保护新宾县生态环境,2006-2021年5-9月调查并分析该县东北部林区的鳞翅目蛾类昆虫,得出该县蛾类昆虫年际资源变化及发生动态情况。结果表明,2014-2017年捕捉的蛾类个体数最多,占总调查个体数的31.22%;而2018-2021年捕捉的蛾类个体数最少,占总调查个体数的18.62%。天蛾科、尺蛾科和夜蛾科的物种数在该县蛾类中处于优势地位,分别为20、19、22种,分别占总种数的16.81%、15.97%和18.49%。2016年调查的个体数最多,为11 186只,优势度系数极高,多样性指数和均匀度极低。在这16年中,有6年是大蚕蛾科的银杏大蚕蛾种群数量占据优势,说明银杏大蚕蛾是栖息在该县的特有优势种群。蛾类多样性年际动态结果显示,2014年后种内竞争动态平衡,种群数量保持稳定无明显变化,2020年夜蛾科和天蛾科蛾类受到环境因素干扰致使种群数量减少。不同年份蛾类群落相似性结果显示,林区蛾类群落结构稳定,相邻两年的相似性数值较高。

A New Family of Moths from the Middle Jurassic(Insecta:Lepidoptera)

Three lepidopteran species, from the Middle Jurassic Daohugou beds （inner Mongolia, China）, are described in a new family, Mesokristenseniidae, and new genus, Mesokristensenia, which could represent the sister group of the Micropterigidae. Mesokristensenia differs from all extant Lepidoptera, but one genus （Agathiphaga, Agathiphagidae）, in retaining four median veins in the forewing, a plesiomorphy also present in many Trichoptera. Evidence for placing Mesokristensenia in the Lepidoptera includes four traits, notably a previously unrecorded autapomorphy of this insect order： beyond stem Ml＋2, vein M1 is bent and connected to cross-vein r-m （in both wing pairs）. Among 24 characters taken into account to assess the systematic position of Mesokristensenia, 12 are considered informative for a cladistic analysis involving this fossil taxon and the four suborders recognized in present-day Lepidoptera （Zeugloptera, Aglossata, Heterobathmiina, and Glossata）.

Toxicity and antifeedant activity of essential oils from three aromatic plants grown in Colombia against Euprosterna elaeasa and Acharia fusca(Lepidoptera:Limacodidae)

Objective:To determine the biological effects of essential oils(EOs) isolated from Cymbopogon iiardus,Cymbopogon Jlexuosus and Cvrnbopogon marlinii grown in Colombia against two Lepidoptera larvae,common pests in the oil palm.Methods:Specimens were captured in the field and the antifeedant activity and dermal contact lethality of EOs were measured against Acharia fusca and Euprosterna elaeasa(Lepidoptera:I.imacodidae) at various concentrations 0.002-0.600 μL/cm^3 and 0.002-8 μL/g,respectively.Results:All EOs exhibited strong antifeedant and toxicity activity toward Acharia fusca and Euprosterna elaeasa larvae.Cymbopogon marlinii oil was llie most active againsl both pest insect species,although all tested EOs were better than the synthetic;repellent IR535 on both insects.Conclusions:Colombian EOs have potential for integrated pest management programs in the oil palm industry.

Complete mitogenome of the Painted Jezebel, Delias hyparete Linnaeus （Lepidoptera： Pieridae） and its comparison with other butterfly species

In the present study, we report the first complete mitochondrial genome （mitogenome） of the Painted Jezebel, Delias hyparete. The mitogenome ofDelias hyparete is 15 186 bp in length, and has typical sets of 37 genes： 13 protein-coding genes （PCGs）, 2 ribosomal RNAs, 22 transfer RNAs and a non-coding A＋T-rich region. All protein-coding genes are initiated by ATN codons, except for C01, which is tentatively designated by the CGA codon, as observed in other butterfly species. A total of 10 PCGs harbored the complete termination codon TAA or TAG; while the C01, C011and ND5 genes ended at a single T residue. All 22 tRNA genes show typical clover structures, with the exception of the tRNAser（AGn） which lacks the dihydrouridine （DHU） stem and is instead replaced by a simple loop. Thirteen intergenic spacers totaling 153 bp, and 13 overlapping regions totaling 46 bp are scattered throughout the whole genome. The 377 bp long olD. hyparete A＋T-rich region is not comprised of large repetitive sequences, but harbors several features characteristic of the lepidopteran insects, including the motif ATAGA followed by an 18 bp poly-T stretch, a microsatellite-like （AT）s element preceded by the ATTTA motif, an 10 bp polyA-like stretch （AAAAATAAAA） present immediately upstream tRNAMet.

Insecticidal Activity and Field Efficacy of Novel Insecticide Cyhalodiamide against Different Lepidoptera Pests

[ Objective] The paper was to study the insecticidal activity and field efficacy of cyhalediamide, a novel insecticide developed by Zhejiang Research Institute of Chemical Industry, Ltd. [ Method] Toxicity of cyhalodiamide against Plutella xylostella, Spodoptera exigua, Prodenia litura and Chilo suppressalis were tasted in the laboratory by leaf-dipping method, and the field efficacy of cyhalodiamide against P. xylostella, S. exigua, P. litura, Pieris rapae, C. suppressalis and Cnaphalocrocis medinalis was evaluated. [ Result] The LCs0 values of cyhalodiamide against P. xylostella, S. exigua, P. litura and C. suppressalis were 0. 046, 0.072, 0.071 and 1.95 mg/L, respectively, almost equivalent to that of flubendiamide and ehlorantraniliprole. The control efficacy of 20% Z4042 SC （30 g/hm2） against P. xylostella, S. exigua, P. litura and P. rapae was 90.1% - 96.3 % after spraying for 7 d, and its control efficacy against C. suppressalis and C. medinalis was 82.9% -90.5% after spraying for 15 d. No crop injury was observed at the test dosage. [Conclusion] The study provided reference for field control against Lepidoptera pests.

Hyperparasitism of Homona coffearia Nietn. (Lepidoptera: Tortricidae), the Tea Tortrix of Sri Lanka: Implications for Biological Control

Tea tortrix, Homona coffearia Nietner (Lepidoptera: Tortricidae), is a seasonal pest of tea in Sri Lanka. Though it is active in dry weather, it is observed that populations do occur in wet weather causing serious damage to tea. The parasite, Macrocentrus homonae Nixon (Hymenoptera: Braconidae), controls the tortrix populations, but the efficiency of Macrocentrus has been reduced on account of hyperparasites in recent times. Level of hyperparasitism was studied in some tea tortrix prone areas in the up country region to study how this affected the tortrix populations during wet weather. The hyperparasitism varied during the study period of which average values observed ranged from 35% to 52% in the plantations studied. A negative linear relationship was observed between the average number of parasite cocoons in a cocoon mass and the percentage hyperparasitism. Three generations of tortrix were evident during the study period of May to November 2005. It is observed that tortrix populations do occur in dry and wet weather, and that hyperparasitism has been identified as the major cause affecting the efficient control of tortrix by the parasite. Possibilities of tea tortrix control in wet weather are discussed.
