Summary: The aryl hydrocarbon receptor (AhR) and aryl hydrocarbon receptor nuclear translocator (ARNT) were characterized in D. armandi. They are highly expressed in the adult and larval stages and mainly expressed in the midgut and Malpighian tubules of adults. Their expression is induced by terpenoids and they play a role in regulating the expression of detoxification enzymes. Silencing these genes increases the susceptibility of D. armandi to certain compounds and reduces detoxification enzyme activity.

Summary: The study suggests that the CYP6 family plays a key role in determining the susceptibility of Dendroctonus armandi to (+)-alpha-pinene, and their inhibition significantly increases adult mortality exposed to the compound. Additionally, exposure to piperonyl butoxide further enhances the sensitivity to (+)-alpha-pinene.

Summary: This study sequenced and characterized two CYP6 genes from Chinese white pine beetle and revealed their expression characteristics and functions. The expression of these genes varied significantly in different developmental stages and tissues, and was significantly induced after feeding on pine phloem or exposure to terpenoids. Silencing these genes increased sensitivity to terpenoids and led to a significant increase in adult mortality.

Summary: This study reveals the important role of cytochrome P450 enzyme CYP4BQ1 in the detoxification process of bark beetles against oleoresin terpenes. CYP4BQ1 is highly expressed in both adult and larval stages of the beetles, particularly in the fat body, midgut, and Malpighian tubules of adults. The expression of CYP4BQ1 is significantly increased after exposure to (+)-alpha-pinene, and its depletion decreases the beetles' tolerance to the compound. Furthermore, (+)-alpha-pinene induces CYP4BQ1 expression through activation of the ROS/CncC signaling pathway.

Summary: The sulfakinin (SK) signaling pathway plays a positive and significant role in feeding regulation in the Chinese white pine beetle, Dendroctonus armandi. The expression levels of SK and SKR genes vary between male and female adults, as well as different developmental stages, tissues, and starvation/re-feeding states. Targeting the SK pathway could provide a potential molecular target for pest control.

Summary: In this study, the expression patterns and tissue distribution of DaKr-h1 and DaBr-C genes were identified and characterized in different developmental stages of Dendroctonus armandi. The results showed that these genes were induced by JH and 20E and played important roles in metamorphosis. The knockdown of DaKr-h1 resulted in precocious metamorphosis and abnormal morphology, while the knockdown of DaBr-C led to increased emergence and the formation of small-winged adults.

Summary: This study identified genes encoding key enzymes involved in the synthesis of exo-brevicomin in the Chinese white pine beetle, providing insight into the biosynthesis pathway. The expression of CYP6CR12 and DaZ-noDH in female beetles is closely correlated with exo-brevicomin synthesis, indicating a potential role in semiochemical biosynthesis pathways.

Summary: Bark beetles rely on detoxification enzymes to overcome host defensive oleoresin terpenes. Insect Carboxylesterases (CarEs) are important for detoxification of plant allelochemicals and insecticides. However, the specific functions of CarE genes in metabolizing exogenous substances in the Chinese white pine beetle are still unclear. This study sequenced and characterized six CarE genes from D. armandi and found that DaEST3 plays a significant role in determining the tolerance to host allelochemicals in this beetle.

Summary: The Chinese white pine beetle, Dendroctonus armandi, is a destructive pest of coniferous forests in the middle Qinling Mountains of China. Research has shown that its food intake is regulated by the sNPF signaling pathway, and RNA interference knockdown of sNPF and sNPFR significantly increased mortality, reduced food intake, and body weight.

Summary: Results show that pyrethrum vapor induces spatial repellency in Aedes albopictus, a major vector of dengue and West Nile viruses. Using electroantennogram recordings, it was found that five of the six pyrethrins elicited responses, with four activating olfactory-receptor neurons and inducing repellency in the mosquitoes. This study lays a foundation for future research on pyrethrins and the development of new mosquito repellents.

Summary: This study investigated the olfactory responses of Endoclita signifer larvae, a polyphagous lepidopteran species that feeds on eucalyptus, to the chemical environment they encounter during development. A total of 32 volatiles were identified from eucalyptus trunk and soil, among which 14 showed electroantennal activity and five were newly identified compounds. The behavioral bioassay revealed that beta-pinene and the imitation ratio of six key volatiles in eucalyptus trunk were attractive to the fifth-instar larvae, but the presence or absence of beta-pinene in the mixture had a negative impact on attraction. The appropriate ratio of main compounds in eucalyptus trunk volatiles played a crucial role in the behavior choice of fifth-instar larvae.

Summary: The antifreeze protein gene of Dendroctonus armandi is crucial in the cold tolerance of overwintering larvae, and its regular threonine-cystine-threonine motif enhances the antifreeze activity. The study provides insights into the biology of the most destructive forest pest in China and offers a theoretical basis for new pest control methods.

Summary: This study analyzed volatile chemical compounds released from the granary weevil Sitophilus granarius and identified two key compounds, 3-hydroxy-2-butanone and 1-pentadecene, which played important roles in the electrophysiological and behavioral responses of this insect. These compounds have potential in developing new approaches for monitoring and managing insect pests in stored grain, reducing postharvest loss.
