Influence of rice black streaked dwarf virus on the ecological fitness of non-vector planthopper Nilaparvata lugens （Hemiptera： Delphacidae）

Rice black streak dwarf virus （RBSDV） is transmitted by the small brown planthopper （SBPH）, Laodelphax striatellus （Fallen）. Non-vector rice brown planthopper （BPH）, Nilaparvata lugens （Stal）, shares the same host rice plants with SBPH in paddy fields. The changes in nutritional composition of rice plants infected by RBSDV and the ecological fitness of BPH feeding on the infected plants were studied under both artificial climate chamber and field conditions. Contents of 16 detected amino acids and soluble sugar in RBSDV infected rice plants were higher than those in the healthy ones. On the diseased plants BPH had significantly higher nymphal survival rates, nymphal duration of the males, weight of the female adults, as well as egg hatchability compared to BPH being fed on healthy plants. However, there was no obvious difference in female nymph duration, longevity and fecundity. Defense enzymes （superoxidase dismutase, SOD and catalase, CAT） and detoxifying enzymes （carboxylesterase, CAE and glutathione S-transferase, GST） in BPH adults fed on diseased plants had markedly higher activities. The results indicate rice plants infected by RBSDV improved the ecological fitness of the brown planthopper, a serious pest but not a transmitter of the RBSDV virus.     

Invasion history of Solenopsis invicta （Hymenoptera： Formicidae） in Fujian,China based on mitochondrial DNA and its implications in development of a control strategy

One of the most invasive species worldwide, Solenopsis invicta Buren, has been described in China since 2003. Recent studies have suggested that China populations are the result of introductions from the USA; however, detailed molecular studies need to be performed in order to understand the expansion and potential multiple introductions from other countries into China. As there were populations of red imported fire ant, S. invicta in different areas and with different methods of introduction, mitochondrial cytochrome oxidase Ⅰ gene was used as a marker from 12 populations in four cities in Fujian Province, China, to determine the relationship of invasion among these populations. The three most common haplotypes previously describe in invasive populations of S. invicta： H5, H22 and H36, were found in Fujian. However, frequencies in each city were different. For instance, three populations from Longyan city which invaded with waste plastics, shared haplotype H5. Populations from Xiamen city and Jinjiang city which dispersed with nursery stock, sward and scrap leather, shared haplotype H22. The population from Nanyan village of Xinluo district, Longyan city, bore haplotype H36. Mitochondrial data reveals that the invasion history of S. invicta in Fujian Province is complex, including multiple invasions probably from other provinces within China. Security measures to prevent S. invicta spreading within China are as important as from overseas.

Colonization patterns of the red turpentine beetle,Dendroctonus valans （Coleoptera： Curculionidae）, in the Luliang Mountains,China

The alien red turpentine beetle （RTB）, Dendroctonus valens LeConte, is one of the most economically destructive forest pests in China, having killed more than 6 million pines in recent years. There is a need to understand the basic biology and ecology of the beetle in order to develop an effective monitoring and management strategy. In this study, the effects of hillside exposure （south- and north-facing）, host-tree locations according to relief （valley, mid-slope, and ridge-top） and tree diameters on RTB colonization were investigated in one valley （3 sites）. The results showed that （i） RTB clearly preferred colonizing pines growing on south-facing hillsides, especially in the valley; （ii） RTB preferred to colonize the pines growing at the valley rather than pines growing at mid-slope or on ridge-top; （iii） RTB preferred to colonize trees with large diameter over small and medium-sized pines; （iv） the attack density of RTBs （measured by pitch tubes/pine） was obviously higher on larger trees standing in the valley than other trees standing at other places. We conclude from RTB colonization patterns, that RTB prefers to attack large trees in the valley, which may be useful in developing a pest-management strategy.     

温度对莲草直胸跳甲成虫繁殖特性和卵孵化的影响

莲草直胸跳甲是恶性入侵杂草喜旱莲子草的有效天敌。为探明莲草直胸跳甲成虫繁育的适宜温度条件和卵的低温冷藏适期,本文研究了莲草直胸跳甲成虫在25、27、30、32、35℃下的存活、取食和产卵特性及卵在15℃下冷藏不同时期的孵化率。结果表明:在25～35℃,莲草直胸跳甲成虫的生存曲线差异显著;随着温度的升高,雌雄成虫寿命呈缩短趋势,表现为25℃>32℃>35℃;但27和30℃的生存曲线与25和32℃差异均不显著。温度对莲草直胸跳甲成虫的取食量和产卵量均有显著影响,在25～35℃,随着温度的升高,跳甲的取食量和产卵量呈下降趋势;成虫期取食量、日均产卵量和世代产卵量表现为25℃>27℃、30℃>32℃>35℃;成虫期取食量和世代产卵量呈显著正相关,相关系数为0.960。将莲草直胸跳甲卵在15℃下冷藏1～10d后转移至25℃,其孵化率均可达100%,但孵化进度则有差异,孵化高峰期随着冷藏时间的延长而提前。与未经冷藏的卵(对照)相比,在15℃下冷藏1d,莲草直胸跳甲卵的始孵化日提前1d,但高峰期不变,均在第5天;在15℃下冷藏4、7和10d后,其孵化高峰期分别较对照提前1、2和3d。可见,在25～35℃时,25℃是莲草直胸...
