Toxicity of Consecutive Treatments Combining Synthetic and Organic Miticides to Nurse Bees of Apis mellifera Open
Varroa destructor, an ectoparasitic mite of honey bees, is a major contributor to global colony declines. To manage infestations, beekeepers frequently apply both synthetic and organic miticides—sometimes in combination. While much attenti…

Exploring the potential role of defensins in differential vector competence of body and head lice for Bartonella quintana Open
Background The body and head lice of humans are conspecific, but only the body louse functions as a vector to transmit bacterial pathogens such as Bartonella quintana . Both louse subspecies have only two antimicrobial peptides, defensin 1…

Histological confinement of transglutaminase-mediated nit sheath crosslinking is essential for proper oviposition and egg coating in the human head louse, Pediculus humanus capitis Open
Background Head louse females secrete liquid gel, which is mainly composed of the louse nit sheath protein 1 (LNSP1) and LNSP2, when they lay eggs. The gel is crosslinked by transglutaminase (TG) to form the nit sheath, which covers most o…

Validation of reference genes for quantitative real‐time polymerase chain reaction assay of honeybee under various pesticide treatment conditions Open
In quantitative real‐time polymerase chain reaction (qRT‐PCR), target gene expression levels are normalized to internal reference gene(s) that are stably expressed across different conditions to determine whether they are up‐ or down‐regul…

CopE and TLR6 RNAi-mediated tomato resistance to western flower thrips Open
The western flower thrips (WFT; Frankliniella occidentalis) is a mesophyll cell feeder that damages many crops. Management of WFT is complex due to factors such as high fecundity, short reproduction time, ability to feed on a broad range o…
