Since its introduction from North America, Dendroctonus valens LeConte has become a destructive forest pest in China. Although gut aerobic bacteria have been investigated and some are implicated in beetle pheromone production, little is known about the abundance and significance of facultative anaerobic bacteria in beetle gut, especially with regards to effects of oxygen on their role in pheromone production. In this study, we isolated and identified gut bacteria of D. valens adults in an anaerobic environment, and further compared their ability to convert cis-verbenol into verbenone (a multi-functional pheromone of D. valens) under different O-2 concentrations. Pantoea conspicua, Enterobacter xiangfangensis, Staphylococcus warneri were the most frequently isolated species among the total of 10 species identified from beetle gut in anaerobic conditions. Among all isolated species, nine were capable of cis-verbenol to verbenone conversion, and the conversion efficiency increased with increased oxygen concentration. This O-2-mediated conversion of cis-verbenol to verbenone suggests that gut facultative anaerobes of D. valens might play an important role in the frass, where there is higher exposure to oxygen, hence the higher verbenone production. This claim is further supported by distinctly differential oxygen concentrations between gut and frass of D. valens females.

Fighting and aggressive sound determines larger male to win male-male competition in a bark beetle

Zhu-Dong Liu, Jacob D. Wickham, Jiang-Hua Sun

Summary: Intrasexual selection in D. valens bark beetles involves male-male competition over females, with larger males usually winning. Experiments showed that larger males won the majority of contests, and there was a correlation between body size and aggressive behaviors such as sound-emitting.

A new bacteria-free strategy induced by MaGal2 facilitates pinewood nematode escape immune response from its vector beetle

Chi Zhang, Jacob D. Wickham, Lilin Zhao, Jianghua Sun

Summary: The pinewood nematodes only introduce a few bacteria to its vector beetle when dispersed, showing weak binding ability especially with Serratia marcescens, which can be detrimental to the beetle. The pattern-recognition receptor MaGal2 in the vector beetle is up-regulated after loading with the nematodes and forms aggregates with associated bacteria. This study reveals a previously unknown immune evasion strategy of the plant pathogen inside its vector and sheds new light on the role of bacteria in parasite-host interactions.

Major ascaroside pheromone component asc-C5 influences reproductive plasticity among isolates of the invasive species pinewood nematode

Meiping Zhao, Jacob D. Wickham, Lilin Zhao, Jianghua Sun

Summary: Pheromones play a role in regulating reproductive plasticity in pinewood nematodes, influencing fecundity in both invasive and native strains. The major pheromone component asc-C5 is identified as a key player in this process, providing new insights into the reproductive strategies of invasive species.

Summary: Risk plays a role in mediating the level of cooperation in parasitoid wasps, with higher mortality risks leading to more cooperation and lower risks leading to more frequent free riding. This study provides an experimental demonstration of risk-driven cooperation in parasitoids.

Rapid Assessment of Cerambycid Beetle Biodiversity in a Tropical Rainforest in Yunnan Province, China, Using a Multicomponent Pheromone Lure

Jacob D. Wickham, Rhett D. Harrison, Wen Lu, Yi Chen, Lawrence M. Hanks, Jocelyn G. Millar

Summary: The Cerambycidae family is diverse and ecologically important, with long-lived larvae of concern as invasive species. Advances in cerambycid pheromone chemistry have led to the development of multispecies lures. This study showed the potential for using generic lures to detect and monitor cerambycid populations, with trap height, slope, elevation, and leaf-area index being important determinants of distribution. Further research is needed to refine lure blends and understand temporal and spatial dynamics of cerambycid communities.

Insect-facilitated propagation of mycotoxic fungi in grain storages: association of Sitotroga cerealella Olivier with Aspergillus flavus link

A. A. Khan, U. Umar, S. Ejaz, H. Riaz, M. Batool, T. Chen, F. Ahmad, Q. Saeed

Summary: This study found that a significant quantity of wheat is lost during storage due to insect and fungal pest complexes. The study also identified Sitotroga cerealella as an important factor in propagating mycotoxic fungi. The prevalence of Aspergillus flavus was higher when S. cerealella co-infested the grain with fungal species. Additionally, the study found that adult moths were attracted to fungal contaminated seeds. Further investigation is suggested to understand the chemical basis of the mutualistic association between A. flavus and S. cerealella for efficient management of grain losses.

Summary: Quantitative reverse transcription polymerase chain reaction (qRT-PCR) is a powerful technique for studying gene expression, but it is important to use stable reference genes under different experimental conditions. In this study, we analyzed the stability of eight candidate reference genes in the pine wood nematode (PWN) across different temperature and developmental stages. We confirmed the stability of two genes and found that EF1 gamma was the most stable gene under different conditions.

Summary: The cotton bollworm is a significant pest that causes damage to crops and vegetables. Traditional chemical pesticides cannot effectively control this pest due to its high fertility and short generation time. Researchers have discovered small molecules that disrupt insect molting, reducing the weight accumulations and fertility of cotton bollworm. Additionally, by inhibiting the function of sterol carrier protein, the life table parameters of cotton bollworm can be significantly reduced. These findings provide important insights for developing effective and sustainable chemical treatments.

Summary: This study aimed to identify the best diagnostic method for the early detection of goat warble fly infestation (GWFI) by comparing three enzyme-linked immunosorbent assay (ELISA) methods. The results showed that the indirect ELISA with the crude antigen of P. silenus was more sensitive and accurate. This method can accurately detect the prevalence of GWFI in goats in the Punjab region.
