Trehalases (TREs) are pivotal enzymes involved in insect development and reproduction, making them prime targets for pest control. We investigated the inhibitory effect of three thiazolidinones with piperine skeletons (6a, 7b, 7e) on TRE activity assessed their impact growth fall armyworm (FAW),

Difenoconazole is a highly effective and broad-spectrum triazole bactericide pesticide was generally applied to protect cure foods such as vegetables fruits.

As illustration, it provides overview the curriculum used initial school principals at Beijing Normal University. Design/methodology/approach draws mainly on writing research from China, Australia USA explore China. Findings In addition rich description paper's main findings comprise seven key challenges that confront as...

This study uses city level panel data covering China's 262 cities for the period 2004–2012 and employs dynamic system generalized method of moments (GMM) model with instrumental variables regression technique to investigate empirically impact foreign direct investment on urbanization in China. The finds that average has played a significantly positive role development urbanization. However, varies from region region. Foreign coastal but no significant inland Apart investment, suggests...

Trehalase inhibitors prevent trehalase from breaking down trehalose to provide energy. Chitinase inhibit chitinase activity affecting insect growth and development. This is an important tool for the investigation of regulation metabolism chitin in reproduction. There are few studies on or inhibitors' In this study, ZK-PI-5 ZK-PI-9 were shown have a significant inhibitory effect trehalase, significantly inhibited female pupae. We investigated reproduction Spodoptera frugiperda using these new...

The white-backed planthopper, Sogatella furcifera (Horváth), is a destructive migratory pest in east and southeast Asia. Huge populations stemming from annual migrations by this insect have caused series of devastating losses to rice production. There been numerous early immigrations five the past 10 yr but few others. fluctuation immigration evident, mechanism behind these fluctuations unclear. This research aimed determine underlying causes for immigration. We used trajectory analysis...

Large numbers of the small brown planthopper Laodelphax striatellus (Fallén) (Hemiptera: Delphacidae) occur in temperate regions, causing severe losses rice, wheat, and other economically important crops. The planthoppers enter diapause third- or fourth-instar nymph stage, induced by short photoperiods low temperatures. To investigate geographic variation L. diapause, we compared incidence nymphal under various constant temperature (20 27 °C) a photoperiod 4:20, 8:16, 10:14, 12:12, 14:10,...

Decentralised economic development initiatives empowering local governments have gained currency in both developed and developing contexts. The empowerment of county China is a case point. This study uses difference-in-differences (DID) the fixed-effects model with panel data (1997–2008) counties Zhejiang Province to empirically investigate different impacts reform on economies fiscal revenue (FR). results reveal that has not promoted as expected but significantly increased FR. had larger...

Southern rice black-streaked dwarf virus (SRBSDV) caused serious losses. After the first outbreak in 2009 northern Vietnam and southern China, ravaged crops again on enormous scales 2010, but infections have decreased sharply since 2011. We presumed that sudden epidemics fadeout of SRBSDV would be closely related to migratory events insect vector, Sogatella furcifera. This study sought source area using trajectory analysis method, revealed relationship between dynamics migration S. furcifera...

The Sogatella furcifera (Horváth) is a notorious and destructive insect pest, targeting >4 million hectares of rice cultivated in the Hunan Province. To understand immigration dynamics, we collected S. light trap catches from 2006 to 2012 at Niangxiang, Linxiang, Hanshou. We conducted migration analysis estimate source for northeastern Province June. Moreover, dissected ovaries classify population characteristics. found that first appearance occurred late April early May, with June as...

The Sogatella furcifera (Horváth) is an important migrating rice pest whose outbreak may be caused by large-scale congregated landings. Hitherto, the meteorological factors that influence landings were thought to rainfall and downdraft. However, for migratory insects on a plateau, low temperature another key factor leading no reports have been published. Therefore, this paper evaluates reason landing in mountainous area Yuanjiang via light trap monitoring. backgrounds during catch peaks...

Sogatella furcifera (Horváth) is a migratory rice pest that periodically erupts across Asia, and early immigration an important cause of its outbreak. The S. into southern China shows evident annual fluctuations. In the spring 2012, huge size immigrant population large number peaks were at levels rarely seen prior to year. However, little research has been done on entire process round-trip migration clarify development population, long-distance final eruption. this study, light-trap data for...

Elizabethkingia anophelis is an emerging pathogen that causes life-threatening infections in neonates and immunocompromised patients. In this study, we performed next-generation sequencing (NGS) to characterize 10 E. strains isolated from clinical patients Nantong, China. Core, accessory, unique genomes were composed of 2,891, 1,633, 498 genes, respectively. Based on genetic screening for antimicrobial resistance genes (AMRs), all carried the same AMRs, including blaB, blaCME, blaGOB. The...

Abstract Rapid urban growth has become a global phenomenon. As these city populations expand, governance is even more of daunting challenge in many countries. China not an exception. It at once transitional state still undergoing urbanization and economic development; it also currently experiencing slowing economy. China's cities must simultaneously continue to improve the quality life while maintaining social stability. Using Guangzhou as example mega‐cities, this study explores financing...

Insect tolerance to insecticides is closely related the host plant. Migratory insects flying downwind and landing randomly may face host-plant switching after migration. However, it not clear whether affects of migratory insecticides. In present work, Cnaphalocrocis medinalis, a pest destructive rice, was studied explore this issue. The results show that switch reduced susceptibility rice wheat larvae populations abamectin but increased chlorpyrifos, indicating resulted in different Enzyme...

Abstract The white-backed planthopper, WBPH, Sogatella furcifera (Horváth) is a plant pest that migrates long-distances. migration pathway of WBPH in eastern China coincides with the north-south round trip East Asian monsoon. However, Yunnan China, which affected by two monsoon systems, unclear. Light-trap data and analysis female ovarian development showed peak period immigration into western was earlier than Yunnan. Using meteorological reanalysis flight parameters trajectory modeling...
