Molecular characterization and expression of two enzymes from Dendroctonus armandi, with phloem feeding and juvenile hormone

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2021
The Chinese white pine beetle, Dendroctonus armandi Tsai and Li, is a serious native pest in the Qinling Mountains of China. exo-Bevicomin, as the main component of bark beetle pheromone, is released by the female D. armandi. In this paper, we identified two genes encoding, (Z)-6-nonen-2-ol dehydrogenase and CYP6CR, that are known to be involved in xo ...

Presence and roles of myrtenol, myrtanol and myrtenal in Dendroctonus armandi (Coleoptera: Curculionidae: Scolytinae) and Pinus armandi (Pinales: Pinaceae: Pinoideae)

Pest Management Science, 2019
AbstractBACKGROUNDInsect pheromones and host volatiles are important for pest control due to their high efficiency and low potential for environmental pollution. The functions of myrtenol, myrtanol and myrtenal in pest–host interactions are unknown.

Knockdown of Cyp6cr2 and Cyp6de5 Reduces Tolerance to Host Plant Allelochemicals in the Chinese White Pine Beetle Dendroctonus Armandi

SSRN Electronic Journal, 2022
Bark beetles rely on detoxifying enzymes to resist the defensive terpenoids of the host tree. Insect cytochrome P450 (CYPs) plays a key role in the detoxification of pesticides and plant allelochemicals. CYP6 family is unique to Insecta, and its biochemical function is basically related to the metabolism of exogenous substances.

Dendroctonus armandi (Curculionidae: Scolytinae) cytochrome P450s display tissue specificity and responses to host terpenoids

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2016
Bark beetles oxidize the defensive allelochemicals of their host trees both to detoxify them and convert them into components of their pheromone systems which were catalyzed by cytochrome P450 enzymes (CYPs) and occur in different tissues of the insect.

Function of mevalonate pathway genes in the synthesis of frontalin in Chinese white pine beetle,Dendroctonus armandi(curculionidae: Scolytinae)

Archives of Insect Biochemistry and Physiology, 2021
AbstractThe Chinese white pine beetle (Dendroctonus armandiTsai and Li) is a significant pest of pine forests in the Qinling and Bashan Mountains of China. Adult males commonly produce frontalin using precursors synthesized through the mevalonate pathway, which is regulated by juvenile hormone III (JHIII).

Identification, expression patterns and RNA interference of Capa peptide receptors in Dendroctonus armandi larvae under cold

Journal of Applied Entomology, 2021
AbstractCapa peptides are of great importance for both understanding the control of salt balance by neuropeptides and revealing the mechanisms of response to cold stress. Presently, research on the physiological function of neuropeptides typically includes identifying and analysing specific receptors and their interactions.

Isolation and expression of five genes in the mevalonate pathway of the Chinese white pine beetle, Dendroctonus armandi (Curculionidae: Scolytinae)

Archives of Insect Biochemistry and Physiology, 2020
AbstractThe Chinese white pine beetle Dendroctonus armandi (Tsai and Li) is a significant pest of the Qinling and Bashan Mountains pine forests of China. The Chinese white pine beetle can overcome the defences of Chinese white pine Pinus armandi (Franch) through pheromone‐assisted aggregation that results in a mass attack of host trees.

Characterisation of GST genes from the Chinese white pine beetle Dendroctonus armandi (Curculionidae: Scolytinae) and their response to host chemical defence

Pest Management Science, 2015
AbstractBACKGROUNDBark beetles rely on their detoxifying enzymes to resist the defensive terpenoids of host trees. Glutathione S‐transferases (GSTs) conjugate xenobiotic compounds with a glutathione moiety (GSH) and often work in tandem with cytochromes P450 or other enzymes that aid in the detoxification, sequestration or excretion of toxic compounds ...
