引用

insect Science 2006年第4期13卷 319-323页

作者： JIAN-QUAN YANG JIA-HUA CHEN JUAN-JUAN LIU beneficial insects lab Fujian Agriculture & Forestry University Fuzhou China

The genus Indabracon van Achterberg, 1993 was discovered in China, and one new species （I. bicolor sp. nov.） of this genus is fully described and illustrated in the present paper. A key to the species of the genus is provided. The new species is similar to the Indian species I. trimaculatus （Cameron, 1900） structurally, but differs for example by： basal half of pterostigma yellow; apical half dark brown; smooth postero-lateral area of the third tergite rather small; propodeum with belt of setae dorsally and lamelliform carinae posteriorly; ovipositor sheath approximately 0.60 times the forewing, somewhat longer than metasoma; the first tergite surface distinctly carinate and rugose, especially in its medial area and laterally. The type specimens are deposited in the beneficial insects lab, College of Plant Protection, Fujian Agriculture ＆ Forestry University, China.

Journal of Integrative Agriculture 2024年第11期23卷 3812-3829页

In insects, the number and specificity of antennal lobe glomeruli often reflect the number and diversity of expressed chemosensory genes, which are linked to its ecological niche and specific olfactory needs. The oriental armyworm, Mythimna separata, is an important and common lepidopteran pest of cereal crops. Given its reliance on the olfactory system for crucial behaviors, understanding the evolutionary potential of this system requires a thorough characterization of the anatomical structure of the primary olfactory center. Here, we systematically identified all antennal lobe glomeruli of M. separata based on synaptic antibody immunostaining and mass staining of the olfactory sensory neurons. A total of 69 glomeruli were identified in females and 65 in males, and an intuitive nomenclature based on glomerular positions was applied. Our findings uncovered some sex-specific glomeruli in this species. There were ten female-specific glomeruli and three male-specific glomeruli, except for the macroglomerular complex(MGC) units, with a notable observation that the female labial pit organ glomerulus was larger than its male counterpart. Additionally, we identified four antennal-lobe tracts(ALTs) and retrograde labeling from the calyx revealed that all glomeruli were innervated by the medial ALT projection neurons. The comparison of the olfactory system structures between M. separata and sympatric moths supports their evolutionary convergence in noctuid moths. These results collectively lay the foundation for future studies on olfactory processing in M. separata.

A new species of Anastatus(Hymenoptera:Eulpelmidae) from China,parasitizing eggs of Lycorma delicatula(Homoptera:Fulgoridae)

引用

Zoological Systematics 2015年第3期40卷 290-302页

作者： Zhong-Qi Yang Wan-Yuong Choi Liang-Ming Cao Xiao-Yi Wang Zheng-Rong Hou Research Institute of Forest Ecology Environment and ProtectionChinese Academy of Forestry beneficial insect lab Crop Protection DivisionNational Academy of Agricultural ScienceRural Development Administration Plant Protection Station

A new species of Anastatus Motschulsky, 1859 （Hymenoptera： Eupelmidae）, A. orientalis Yang ＆ Choi, sp. nov. is described from China. It is a solitary endo-parasitoid in egg of the spotted lanternfly, Lycorma delicatula （White）（Homoptera： Fulgoridae）, which causes damages to many ornamental and fruit trees in China. The brief biology of the new parasitoid is also mentioned. The new species has high potential as a biocontrol agent for suppression of the pest because of its parasitism rates of egg masses 30.4% and of eggs 40.2% respectively with sex ratio of female to male 1.9：1.0, as well as the relative easiness for mass rearing. The detailed feature characters and photos of the new species are supplied. Meanwhile, a key to distinguish the present new species from the other close two （A. japonicus and A. bifasciatus） in the genus is provided. Type specimens are deposited in the insect Museum, Chinese Academy of Forestry, Beijing, China.

A New Fossil Scorpionfly(insecta:Mecoptera:Holcorpidae) with Extremely Elongate Male Genitalia from Northeastern China

引用

Acta Geologica Sinica(English Edition) 2017年第3期91卷 797-805页

作者： LI Lei Chungkun SHIH WANG Chen REN Dong Key lab of insect Evolution and Environmental Changes Capital Normal University Department of Paleobiology National Museum of Natural HistorySmithsonian Institution

Since Holcorpa maculosa was first described in 1878, it has attracted lots of attention due to its extremely elongate abdominal segments from the sixth to the eighth. Fossil records of family Holcorpidae are very rare, comprising two species in one genus represented by three fossil specimens, resulting in limited knowledge on the structure and function of holcorpid＇s unique male organ, as well as its evolutionary relationship with other scorpionflies. Herein we describe a new genus with a new species, Conicholcorpa stigmosa gen. et sp. nov., of the Holcorpidae from the Middle Jurassic Jiulongshan Formation near Daohugou Village, Inner Mongolia, China. This is the first holcorpid documented from the Daohugou locality, albeit two previously reported species with extremely elongate male organs but deemed as Family Incertae sedis. C. stigmosa gen. et sp. nov. is the earliest holcorpid hitherto, extending its existence from the Early Eocene to the Middle Jurassic by 114 million years and providing one more early case of presenting exaggerated male body parts for sexual display and/or selection. Our analysis supports the sister relationship between Holcorpidae and Orthophlebiidae. Our results not only enhance our knowledge of the morphology of Holcorpidae but also elucidate the relationship of known species of this family.

Biological control(biocontrol) is a safe, sustainable approach that takes advantage of natural enemies such as predators, parasitic insects or pathogens to manage pests in agroecosystems. Parasitoid wasps, a very large evolutionary group of hymenopteran insects, are well-known biological control agents for arthropod pests in agricultural and forest ecosystems. Here, we summarize the recent progress on the application of parasitoid wasps in biocontrol in China for the last five years. These include species diversity of parasitoid wasps, identification of dominant parasitoid wasps associated with insect pests and biocontrol practices(three types of biological control, i.e., classical, augmentative and conservation biological control) in several Chinese agroecosystems. We then treat different mass-rearing and release technologies and the commercialization of several parasitoid wasp species. We also summarize other work that may have a potential use in biocontrol, including the effect of plant volatiles on parasitoids and recent advance in the molecular mechanisms underlying the host regulation by parasitoid wasps. Future research area and applied perspectives are also discussed, noting that advances in biocontrol technologies in Chinese agriculture informs research at the global level.

Journal of Integrative Agriculture 2019年第4期18卷 716-728页

The brown planthopper, Nilaparvata lugens St?l, has become a major threat in tropical Asian and China since the rice green revolution of the 1960 s. Currently, insecticide application remains the primary choice for controlling this rice insect pest, but heavy use of insecticides poses dangerous risks to beneficial natural enemies and pollinators, and stimulates N. lugens reproductivity, and has caused a resurgence of the pest in the major rice-planting regions throughout Asia. Achieving the long-lasting goal of sustainable management of N. lugens requires understanding of the molecular basis of outbreaks of the pest and the development of environment-friendly pest-control strategies. Here, we review the recent molecular advances in N. lugens research on the aspects of its endosymbionts, virus transmission, insecticide resistance, and interaction between N. lugens and rice plants. We also put forward further research directions that may shed some lights on management of the rice pest.

The impact of habitat fragmentation and isola-tion on the genetic diversity of populations has attracted much attention in studies of meta-population and conserva-tion biology. In this work, using the randomly amplified po-lymorphic DNA (RAPD) technique, we studied the genetic diversity of central, peripheral and peninsular populations of ratlike hamster, which were collected in five locations of the North China Plain and its surrounding areas, in 1999. The study revealed that, i ) the genetic diversity of central population of Raoyang County > the sub-central populations of Gu’an County and Taikang County > the peripheral population of Shunyi District > the peninsular population of Mentougou District; ii) the genetic diversities of the five populations were positively correlated to the nearest dis-tances to the peripheral line of population distribution; iii) there were significant differences of gene frequencies of some RAPD fragments among the five populations. More RAPD fragments disappeared in
