Study on Disaster Migration Sources of Rice Planthoppers and Meteorological Background in Northwest Guangxi During Abnormal Climate Years
To clarify the source regions and atmospheric driving mechanisms of the catastrophic migration events of rice planthoppers in northwestern Guangxi, this study conducted backward trajectory simulations for the peak migration days of rice planthoppers in 2008 using the HYSPLIT 5.0 trajectory model, combined with comprehensive analyses of concurrent meteorological factors such as atmospheric dynamic fields, temperature and humidity fields, and precipitation. The results indicate: (1) Among the six major migration peaks with over 100,000 rice planthoppers being caught per trap in northwestern Guangxi rice-growing areas, the primary sources were the rice-growing regions along the Yunnan-Myanmar border and the northern rice-growing areas of the Indo-China Peninsula. (2) Cluster analysis of backward trajectories for 161 catastrophic peak days revealed three key migration pathways for the catastrophic migration of rice planthoppers in northwestern Guangxi in 2008: the southwest monsoon pathway from Yunnan-Myanmar to the Yunnan-Guizhou Plateau, the cross-border monsoon pathway from the Indo-China Peninsula to river valleys, and the lowland monsoon pathway from the You River to the Hongshui River. Among these, southerly pathways accounted for 86.8% of the total trajectories, constituting the dominant migration route. (3) The southerly warm and moist airflow originating from the Bay of Bengal and the South China Sea at the 850 hPa level served as the primary transport carrier for rice planthopper migration. The high-altitude humid environment formed by rapid temperature recovery and sustained moisture transport during the 2008 spring provided favorable conditions for the migration process. (4) The frequency and volume of rice planthopper migration peaks were significantly correlated with the number of rainy days at night, and increased precipitation duration and intensity would exacerbate migration risks. Additionally, subsiding airflow was a critical dynamic factor contributing to the concentrated landing of rice planthoppers. The results of this study showed that the primary sources of the catastrophic migration of rice planthoppers in northwestern Guangxi in 2008 originated from foreign rice-growing regions in Yunnan-Myanmar and the Indo-China Peninsula, entering through three atmospheric pathways coupled with terrain and monsoon circulation; the migration process was primarily driven by the transport of southerly warm and moist airflow at the 850 hPa level and promoted by abnormal hydrothermal conditions in spring; while nocturnal precipitation and subsiding airflow in the destination areas were key triggers for the concentrated landing of the insect populations.

对褐飞虱各虫态和不同生育期水稻过冷却点的测定及在人工模拟低温条件下耐寒力的比较表明:褐飞虱各虫态的耐寒力明显高于水稻。证明在冬季低温降临后,水稻先行枯萎,褐飞虱在食料缺乏和低温的共同影响下相继死亡。 水稻生存的下限温度在0—-2℃间,可作为褐飞虱在我国越冬的温度指标。据此,对褐飞虱在我国大陆的越冬北界提出了讨论意见。

Outbreaks of the Nilaparvata lugens (Stål), have occurred frequently in China during the past few years, resulting in a broad and significant reduction in rice yield. N. lugens immigrate into China each spring from Southeast Asia, and the Guangxi Zhuang Autonomous Region is the first area affected. Light trap catches for the early season period (March-June) in Guangxi for the past 30 yr have been analyzed, and the catch sequences for five observation stations (Longzhou, Hepu, Yongning Yongfu, and Quanzhou) were studied in detail. It was found that during the past 10 yr the first appearance of N. lugens at light traps occurs earlier, there is a higher frequency of days with large light-trap catches, and catches in southern Guangxi are larger. Recently light-trap catches have also increased in northern Guangxi. It is concluded that the increasing number of immigrants from overseas is one of the primary reasons for the increase in N. lugens outbreaks in the past 10 yr. Global warming, and specifically winter temperature increases, appears to be for a factor accelerating outbreaks of N. lugens in Asia.© 2010 Entomological Society of America

Rice planthopper (RPH) populations of Nilaparvata lugens and Sogatella furcifera periodically have erupted across Asia. Predicting RPH population dynamics and identifying their source areas are crucial for the management of these migratory pests in China, but the origins of the migrants to temperate and subtropical regions in China remains unclear. In particular, their early migration to China in March and April have not yet been explored due to a lack of research data available from potential source areas, Central Vietnam and Laos. In this study, we examined the population dynamics and migratory paths of N. lugens and S. furcifera in Vietnam and South China in 2012 and 2013. Trajectory modeling showed that in March and April in 2012 and 2013, RPH emigrated from source areas in Central Vietnam where rice was maturing to the Red River Delta and South China. Early migrants originated from Southern Central Vietnam (14-16°N), but later most were from Northern Central Vietnam (16-19°N). Analysis of meteorological and light-trap data from Hepu in April (1977-2013) using generalized linear models showed that immigration increased with precipitation in Southern Central Vietnam in January, but declined with precipitation in Northern Central Vietnam in January. These results determined that the RPH originate from overwintering areas in Central Vietnam, but not from southernmost areas of Vietnam. Winter precipitation, rather than temperature was the most important factor determining the number of RPH migrants. Based on their similar population dynamics and low population densities in Central Vietnam, we further speculated that RPH migrate to track ephemeral food resources whilst simultaneously avoiding predators. Migrations do not seem to be initiated by interspecific competition, overcrowding or host deterioration. Nevertheless, S. furcifera establishes populations earlier than N. lugens South China, perhaps to compensate for interspecific competition. We provide new information that could assist with forecasting outbreaks and implementing control measures against these migratory pests.

Brown Planthopper (BPH, Nilaparvata lugens (Stål)) is one of the most serious pests of rice in both temperate and tropical regions of East and South Asia and has become especially problematic over the past few years. In order to analyze the effect of the change of rice cropping system on the population dynamics of BPH, field surveys of the occurrence and distribution of BPH were performed and other relevant data, including light trap data and ovary dissection data were collected in nearly 40 Chinese counties encompassing six provinces (or municipalities), including Hainan, Guangxi, Anhui, Shanghai, Fujian and Guangdong from April to October in 2007.The mixed planting areas of single- and double-cropping rice in China include Hubei, South and Central Anhui, North Hunan, and North Jiangxi. In these areas, double-cropping rice has now been greatly reduced and single-cropping rice has been rapidly increasing since 1997. The surveys revealed that when the immigration peak of BPH occurred in June and July, the single-cropping rice was at the tillering to booting stage and fit for BPH, but early rice had already matured and most of late rice had not yet been transplanted. BPH immigrants from southern rice areas prefer to inhabit and breed in single-cropping rice paddies. Moreover, farming activities between early rice and late rice interrupted the continuous growth of BPH populations in double-cropping rice paddies. As a result, in comparison with data collected 30 years ago, the spatiotemporal dynamics and migration patterns of BPH have dramatically changed in the lower-middle reaches of the Yangtze River. In the mixed planting areas, due to their high suitability, the BPH population in single-cropping rice grew so quickly that it caused serious local damage and there was mass emigration of macropterous progeny to the Yangtze River Delta in late August and early September.Global warming may also affect BPH populations, where results suggest steadily warmer autumns have occurred from the 1990s on, with such conditions gradually the norm. The combination of 'cooler summer' and 'warmer autumn' are conditions known to promote outbreaks of BPH in the lower-middle reaches of the Yangtze River. Immigrant BPH arrivals in late August and September now cause serious damage to late-maturing mid-season rice and late rice in the lower-middle reaches of the Yangtze River.
