Morphology of the Male Reproductive System and Spermiogenesis of Dendroctonus armandi Tsai and Li (Coleoptera: Curculionidae: Scolytinae). [PDF]

J Insect Sci, 2017
Studying the reproductive attributes of pests is central to understanding their life cycle history and in crafting management strategies to regulate, if not bring down, their population below threshold levels. In this article, the morphology of the male reproductive tract, topology of the spermatozoa, and salient features of spermiogenesis in the ...

Are species more harmful in their native, neonative or alien range? Insights from a global analysis of bark beetles

Diversity and Distributions, Volume 28, Issue 9, Page 1832-1849, September 2022., 2022
Abstract Aim Anthropogenic environmental modifications such as climate or land‐use change are causing species to move on their own beyond their native ranges. As this phenomenon will increase in the near future, it is crucial to determine whether range‐expanding species, or neonatives, are more or less likely than native and alien species to impact ...

Silencing of the olfactory co-receptor gene in Dendroctonus armandi leads to EAG response declining to major host volatiles. [PDF]

Sci Rep, 2016
AbstractIn this study, a polymerase chain reaction (PCR) based on homology genes of Orco was utilized to identify DarmOrco, which is essential for olfaction in D. armandi. The results showed that DarmOrco shares significant sequence homology with Orco proteins had known in other insects.

Could bacterial associations determine the success of weevil species?

Annals of Applied Biology, Volume 178, Issue 1, Page 51-61, January 2021., 2021
Abstract The weevil superfamily Curculionoidea is the largest insect group and so the largest animal group on earth. This taxon includes species which represent an important threat to many economically important crops and, therefore, pose a risk to agriculture and food security.

Community structure of gut fungi during different developmental stages of the Chinese white pine beetle (Dendroctonus armandi). [PDF]

Sci Rep, 2015
AbstractThe Chinese white pine beetle is arguably the most destructive forest insect in the Qinling Mountains in Northern China. Little is known about the structure of the fungal communities associated withDendroctonusarmandi, even though this wood-boring insect plays important roles in ecosystem and biological invasion processes that result in huge ...
