Summary: In this study, the researchers analyzed the antennal transcriptome of the Asian corn borer moth and identified multiple odorant-degrading enzyme (ODE) genes associated with odor signal termination. They also found that specific carboxylesterase genes were enriched in different sexes. These findings provide insights into the olfactory functions of the Asian corn borer moth and could potentially contribute to the development of novel pest management strategies.

Summary: Immune functions are costly and dependent on individual condition and resource availability. Host plant quality affects the performance and immune function of phytophagous insects, with polyphagous insects varying immune investment based on host plant species. Larvae of polyphagous moths may exhibit density-dependent prophylaxis and invest more in immune responses in high population densities. Certain host plant species can increase larval investment in specific immune functions, suggesting different host plants may provide protection against different antagonisms for polyphagous species.

Summary: Climate warming is expected to impact the response of species to insecticides. Studies have shown that transgenerational effects play a role in the interaction between insecticides and temperature, influencing factors such as survival, development, and body mass. These results suggest that the effects of insecticides and temperature on species can be additive and influenced by transgenerational effects.

Summary: The expression patterns of odorant receptors in cotton leafworm larvae change across different developmental instars, suggesting a mechanism influencing specific olfactory-guided behavior and food preferences. Functional characterization of SlitOR40 showed instar-specific responses to plant volatiles and knocking out this receptor disrupted larval behavioral plasticity. These findings demonstrate an olfactory mechanism underlying behavioral plasticity during larval development in the cotton leafworm.

Summary: The Illumina-based transcriptome sequencing has become a standard in deciphering the molecular bases of chemical senses in insects, especially in non-model species. In the case of the noctuid Spodoptera littoralis, an unprecedented transcriptomic survey of chemosensory tissues revealed ectopic and sex-biased expression of chemosensory genes, contributing to a more comprehensive understanding of chemical communication in insects.

Summary: Spodoptera frugiperda is an invasive pest in Indonesia that causes significant damage to corn crops. Our study found that besides corn, the pest can also utilize papaya, water spinach, banana, spinach, cucumber, and coco grass as alternate hosts. These plants can be used in the management of the pest, but further research is required to develop sustainable solutions.

Summary: This study found that the fall armyworm can survive and reproduce on bananas, although they prefer maize as their host. The larvae that fed on bananas had a longer developmental duration and slower population growth compared to those that fed on maize. The survival probability and reproductive capacity of the fall armyworm were lower when fed on bananas compared to maize.

Summary: Research shows that larvae of Spodoptera littoralis are attracted to their own frass volatiles, with the key ligand being guaiacol. Bacteria producing guaiacol were isolated from frass of larvae fed on different foods. The study demonstrates that guaiacol is attractive to the larvae and could be used for pest management.

Summary: In this study, 20 candidate CXEs were identified in Holotrichia parallela, with some showing antenna-biased expression. The differential expression of CXEs in male and female antennae implies potential roles in odorant degradation, providing insights into the olfactory mechanism of H. parallela.

Summary: Agriculture is seeking pest control alternatives with lower environmental impact, prioritizing biological control measures over chemical insecticides. This study evaluated the effects of three microbial agents in controlling Spodoptera littoralis, and found that the combination of these agents with low doses of insect growth regulators (IGRs) can be effective in integrated pest management (IPM) programs, except for one combination that showed an antagonistic effect. A product based on lufenuron and the SlNPV is identified as a potential candidate for commercial development.

Summary: In this study, two paralogous antennae-enriched CCEs from Plutella xylostella were identified and functionally characterized, with one enzyme (PxylCCE16c) showing a more essential role in odorant degradation and potential as a novel pesticide target for the notorious moth Plutella xylostella.

Summary: This study predicted the spatial distribution of fall armyworm in five east African countries using the MaxEnt model and various explanatory variables. The results showed that 27% of eastern Africa is currently at risk of fall armyworm establishment, and this risk is expected to increase in the future. It is recommended to integrate the modeling results into a dynamic platform for real-time predictions of fall armyworm occurrence and risk at the farm scale.

Summary: Insects are influenced by different light conditions, and this study found that dim red light during scotophase can enhance mating in the yellow peach moth. The enhancement may be due to an increase in male antennal sensitivity to female sex pheromones caused by up-regulation of pheromone-binding protein genes.

Summary: Volatile plant compounds alter pheromone perception by insects, but the effects of mixture within insect olfactory landscapes are poorly understood. Our study measured the activity of brain neurons and receptor neurons tuned to a pheromone component while exposed to backgrounds of VPCs, showing that VPC salience seems more important than background complexity.

Summary: Mycobacterium abscessus is a highly pathogenic species among fast-growing mycobacteria that infects cystic fibrosis patients. It is able to resist the host innate response by being rapidly internalized by Drosophila phagocytes and thus escaping the antimicrobial peptides.
