Symbiotic Fungi

Woodwasps (Hymenoptera: Siricidae) are saproxylic insects and a common forest pest. Siricid woodwasps are classified into two subfamilies: Siricinae and Tremecinae. All known symbiotic fungi of Siricinae are in the genusAmylostereumBoidin while some species of Tremecinae have been observed to have a relationship with the fungusCerrenaunicolor(Bull.) Murrill. Previous studies about the host searching behavior of woodwasps and their parasitoids have focused primarily on the subfamily Siricinae.We analyzed the role ofC.unicolorvolatiles on the host searching behavior ofTremexapicalisMatsumura (Hymenoptera: Siricidae: Tremecinae) and its parasitoid Ibalia (Tremibalia) japonica Matsumura (Hymenoptera: Ibaliidae). The results of an olfactory response experiment indicated that the females ofT.apicalisand its parasitoid find their respective hosts using volatiles fromC.unicolor. Using DNA barcode, we identified basidiocarps on the trees infested withT.apicalis.The basidiocarps were all white-rot fungi that cause sapwood decay, includingC.unicolor. Two additional species that we identified belonged to genera closely related toC.unicolor.Woodwasp species are known to carry symbiotic fungi in a pair of specialized sacs called mycangia. Notably we found that mycangia-like structures were absent in the abdomens ofT.apicalisfemales. To the best of our knowledge,Xerisspectrum(Linnaeus) (Hymenoptera: Siricidae) is the only reported example of woodwasp species that do not contain symbiotic fungi in their bodies.Our results suggested that: (1)T.apicalisfemales search for host wood that is already infected with sapwood decaying fungus using volatile compounds; (2)T.apicalis’ female parasitoid also uses volatile compounds from fungus to locate wood that is infested with its potential host.

Information Searching Behavior

AbstractWith the rapid development of the online shopping market in recent years, flow theory has become one of the main theories used to explore online consumers’ shopping behaviors. Although flow experience may influence information searching behavior, little is known about this topic. This study explored the impacts of flow experience on online consumers’ information searching behavior in festival shopping. The questionnaire survey was conducted in several universities in China. The data, collected from 154 college students, were analyzed quantitatively. As the three key components of flow experience, perceived pleasure has negative effect on information searching frequency, whereas concentration has positive effect on information searching frequency. Perceived control does not have a significant impact on information searching frequency. It also revealed consumers’ information searching behavior positively affecting their purchase intentions in this special shopping context. We found that flow experience is an important psychological factor influencing online consumers’ information searching behavior. The study enriches the emotional dimension of information behavior model and provides insight into the relationships between positive psychological variables with flow experience as the representation and information searching behavior in shopping context.
