<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Spodoptera frugiperda, omnivorous quarantine pests, are native to the tropical and subtropical regions of the Americas. They have more than 300 host plant species, especially Gramineae, such as corn. They show some typical characteristics, such as strong migration ability, high fecundity, gluttony and rapid evolution of pesticide resistance. In China, they were first found in Yunnan Province in January 2019, and now have been found in 26 provinces. Here, we summarized their distribution range, routes and reasons of diffusion, living habits, infestation characteristics and control measures in a comprehensive view, and also discussed some future research fields for the pests.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The fall armyworm Spodoptera frugiperda (Smith), an important invasive pest, was found in China, in January, 2019 Clarifying spatial pattern of S. frugiperda larvae is useful to the field sampling and investigation of the pest In this study, spatial distribution data of S. frugiperda larvae were investigated in corn seedling stage of 3~4 leaves and 8~10 leaves, respectively.Then, Iwao m*-m model and Taylor power law were used to analyze spatial distribution data of S. frugiperda larvae. The results showed that spatial distribution of S. frugiperda larvae were clustered distribution in whole corn seedling stage, but spatial distribution of S. frugiperda larvae were clustered distribution in corn seedling stage of 3~4 leaves, and was uniform pattern in corn seedling stage of 8~10 leaves. The aggregation degree of S.frugiperda larvae were not dependent on the larvae density in the whole seedling stage and corn seedling stage of 8~10 leaves, but were dependent on the larvae density in corn seedling stage of 3~4 leaves Under the same larvae density and error of sampling, sample quantity was different at different corn seedling stages, ie the earlier the growth period of corn was, the more sampling number was needed.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Octodonta nipae (Maulik), a dangerous quarantine pest for forestry, mainly attacks palm plants, which has caused serious damage to nursery stock for palm plants, ecological environment, and city afforestation. Since this invasive pest was first discovered in 2001 in China, numerous works have been done in the fields of invasive characteristics, biological and ecological characteristics, immune response and the underlying mechanisms, and some results have been achieved O. nipae has a high population genetic diversity. It develops and grows optimally at the temperature range of 26~29℃. It shows no tolerance to extreme temperatures but to some extent owing a plasticity in cold resistance. Syagrus romanzoffiana (Cham) Glassman, Phoenix canariensis Hort ex Chabaud and P sylvestris Roxb are its favorite host plants. O. nipae usually adopts multiple mating strategy for reproduction; when encountering an improper environment, O. nipae responds quickly with activating cellular and humoral immunity. Therefore, O.nipae has characteristics of strong adaptability and reproductive ability, which can help them toinvade most south areas of the Yangtze River in China. In this review, we summarized these related progress in China based on published thesis and papers.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The nipa palm hispid Octodonta nipae (Maulik) is a species of invasive pests, which can cause serious damage to palms.To clarify the effects of age and sex on cuticular hydrocarbons (CHCs) in O. nipae adults, the components and contents of CHCs from O. nipae male and female adults at different ages were analyzed by chemical extraction and gas chromatography mass spectrometry. The results indicated some differences in the content of some CHCs components from O. nipae adults of different age and sex, but the CHCs profiles showed similarities. Total of 21 hydrocarbons, ranging from C18 to C30, were separated from the epidermis of O. nipae adults, including 11 nalkanes, 2 monomethyl alkanes, 1 polymethyl alkane, 3 nalkenes, 1 monomethyl alkene and 3 cycloalkanes.There were significant differences in the content of n-C24, n-C26, 2-meC19 ane, and 1-C20ene, among O. nipaemale or female adults at 1 d, 5 d, 10 d and 15 d after eclosionCHCs of O. nipae adults presented sexual dimorphism. The content of some chemicals, containing n-C20, n-C21, n-C24, n-C26, 2-meC19 ane, 10-meC20 ane, 1-C20 ene, and 1-C22ene, from the mature male adults were significantly higher than those of mature females. Our findings provided a support for the quick identification of closely related species, age, sex and sexual maturity of O. nipae during border inspection and quarantine.]]></description>
