Genetic Basis of Cuticular Hydrocarbon Variation in the Desert Ant Cataglyphis niger

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Cuticular hydrocarbons (CHCs) are a ubiquitous component of ant cuticles that are used for a wide range of chemical signaling functions, especially recognition. Here we tested for a genetic basis of CHC variation in the desert ant Cataglyphis niger. We applied a genomic mapping approach to discover associations between CHCs and 20 quantitative trait ...

Cry78Aa, a novel Bacillus thuringiensis insecticidal protein with activity against Laodelphax striatellus and Nilaparvata lugens [PDF]

, 2018
Transgenic plants expressing insecticidal proteins originating from Bacillus thuringiensis (Bt) have successfully been used to control lepidopteran and coleopteran pests with chewing mouthparts. However, only a handful of Bt proteins have been identified

Brown Planthopper Nudivirus DNA Integrated in Its Host Genome [PDF]

Journal of Virology, 2014
ABSTRACT The brown planthopper (BPH), Nilaparvata lugens (Hemiptera:Delphacidae), is one of the most destructive insect pests of rice crops in Asia. Nudivirus-like sequences were identified during the whole-genome sequencing of BPH. PCR examination showed that the virus sequences were present in all of the

An RNA interference biopesticide reduces reproduction of the honey bee parasite Varroa destructor by down‐regulating embryo development pathways

Pest Management Science, Volume 82, Issue 3, Page 2694-2707, March 2026.
Varroa destructor mites exposed to dsRNA specific in sequence to a V. destructor calmodulin gene significantly effected gene expression of adult female mites sampled 5 days after entering a honey bee brood cell to reproduce. Significantly down‐regulated genes included Calmodulin and were associated with calcium ion binding and embryo developmental ...

Host‐Associated Bacterial Community Changes After Laboratory Introduction Vary With Wolbachia Presence

Environmental Microbiology, Volume 28, Issue 3, March 2026.
The endosymbiont Wolbachia promotes homogenisation and delays the microbial community response of the parasitic wasp Asobara japonica after a significant environmental change. This suggests that key microbial taxa can mediate community shifts and has important implications for experimental design in microbial ecology, particularly in translating lab ...
