“…Reciprocal crosses between these two species resulted in no progeny and demonstrated that they are reproductively incompatible . However, the abundance of ZHJ1 in Zhejiang has gradually declined since 2000 (Zang et al 2005).…”

Temperature is a primary factor that determines geographic insect boundaries and population developments. Insect responses to temperature stress are particularly important in invasive species. Bemisia tabaci is a genetic complex of closely related whiteflies. Invasive and indigenous species were used to test genotype responses to temperature stress. To determine whether thermal tolerance is related to differential expression of heat shock proteins (hsp) under temperature stress in two invasive and native sibling species, commonly referred to as the biotype B and biotype Q of B. tabaci, we analyzed the expression profiles of hsp90 and hsp70 and hsp20 across temperature gradients using real-time quantitative polymerase chain reaction. The B. tabaci invasive species Q is more tolerant to short temperature stress than the indigenous species ZHJ1, and the onset (T on ) or maximal (T max ) temperature induction of hsp expression in the B. tabaci invasive species Q was generally 2-4°C higher than that found in the indigenous species ZHJ1. Our results demonstrate differences in gene expression between these closely related and sympatric B. tabaci sibling species, suggesting that these differences account for the better adaptation of invasive species over indigenous species. These differences may eventually lead to changes in the local and global distribution of both species in a warmer world.

“…As invasive species usually have strong competitive, or high propagation capabilities, it is a general phenomenon among animals and plants that they can exclude and displace native ones, leading to the decrease, or even extinction, of native species populations (Petren and Case 1996;Holway 1999;Gurevitch and Padilla 2004;Bohn et al 2007). Many studies have considered competition between alien invasive species and native species, such as those in plants (Callaway and Aschehoug 2000;Brown et al 2002;Vila and Weiner 2004); insects (Edgerly et al 1993;Juliano 1998;Holway and Suarez 1999;Braks et al 2004;Zang et al 2005); and other animals (Petren et al 1993;Petren and Case 1996;Byers 2000;Wauters et al 2002;Wilson et al 2004). Competition and displacement can therefore be taken as an important mechanism by which many invasive species become dominant in their new ecosystem.…”

“…It causes a disastrous and uncontrollable disease-the pine wilt disease, which is also known as ''pine cancer.'' This disease has been prevalent in the above areas since the 1970s, and has caused huge economic and ecological losses in Asian countries (Yang et al 2003). However, in natural pine forests of these countries there is another widely spread nematode, Bursaphelenchus mucronatus Mamiya.…”

The presence of alien invasive species has serious negative impact on endemic biodiversity, especially on native species that occupy the same niche in the ecosystem. To study the influence of the alien invasive species Bursaphelenchus xylophilus on its native sister species B. mucronatus, the two nematode species were mix-cultured in a fungal mat and mix-inoculated into a susceptible host. By comparing the propagation parameters of both species under competitive and noncompetitive conditions it was shown that the propagation level of B. xylophilus was clearly higher than that of B. mucronatus under laboratory culture. Furthermore, the propagation capacity of B. xylophilus under competitive conditions was much higher than that under noncompetitive conditions, both in laboratory culture and with host inoculation. Bursaphelenchus xylophilus also excluded B. mucronatus when the two species were cultured as a mixture for a longer time. The relative abundance ratios of the two species in natural pinewoods were also determined by random sampling of dying pine trees from regions with different invasion histories. It was noted that with an increase in invasion years the distribution frequency of B. xylophilus increased while that of B. mucronatus decreased. Experimental tests verified our hypothesis that because of its high fecundity and strong competitive ability, the invasive species B. xylophilus out-competed the native species B. mucronatus and displaced it in natural ecosystems. The successful invasion of B. xylophilus is attributed to competitive displacement, which may be one of the ecological invasive mechanisms.

“…Host plant can also contribute to displacement rate. For example, Zang et al (2005b) found that displacement took six generations on cotton but only two on squash starting with equal numbers of biotype B and the indigenous biotype ZHJ1. Similarly, De Barro et al (2006) showed that the minimum number of invaders relative to indigenous individuals required for establishment was lower with cotton -a host more suited to the invader, than with E. cyathophora -a host well suited to both biotypes B and indigenous AN biotypes.…”
