Improvement of colony management in insect mass‐rearing for sterile insect technique applications

Insect Science, Volume 32, Issue 5, Page 1476-1494, October 2025.
Abstract Sterile Insect Technique (SIT) applications against major insect pests and disease vectors rely on the cost‐effective production of high‐quality sterile males. This largely depends on the optimal management of target pest colonies by maximizing the benefits provided by a genetically rich and pathogen‐free mother colony, the presence of ...

Spatiotemporal changes in prevalence of Sodalis glossinidius, Spiroplasma spp. and trypanosome species in wild Glossina tachinoides from Sora‐Mboum animal African trypanosomiasis focus in northern Cameroon

Insect Science, Volume 32, Issue 5, Page 1713-1725, October 2025.
Abstract Sterile Insect Technique (SIT) has proven effective to reduce tsetse population density in large infected areas where animal African trypanosomosis (AAT) and human African trypanosomiasis (HAT) elimination was difficult to achieve. However, the decrease in mass production of insectary‐reared tsetse and the limited but incomplete knowledge on ...

Infection dynamics of endosymbionts that manipulate arthropod reproduction

Biological Reviews, Volume 100, Issue 5, Page 1787-1812, October 2025.
ABSTRACT A large proportion of arthropod species are infected with endosymbionts, some of which selfishly alter host reproduction. The currently known forms of parasitic reproductive manipulations are male‐killing, feminization, cytoplasmic incompatibility, parthenogenesis induction and distortion of sex allocation.

Endosymbiont-free ants: Molecular biological evidence that neither Wolbachia, Cardinium or any other bacterial endosymbionts play a role in thelytokous parthenogenesis in the harvester ant species, Messor barbarus and M. capitatus (Hymenoptera: Formicidae)

European Journal of Entomology, 2013
Thelytokous parthenogenesis is a type of sex determination in which females are produced from unfertilized eggs. Genetic and endosymbiont-induced forms of thelytoky have been described in the Hymenoptera. Our study has revealed that Wolbachia, Cardinium,

Extracellular Vesicles in Arthropods: Biogenesis, Functions, Isolation Methods and Applications

Journal of Extracellular Vesicles, Volume 14, Issue 9, September 2025.
ABSTRACT Extracellular vesicles (EVs) are membrane‐bound nanoparticles secreted by cells that are involved in multiple forms of intercellular communication and show promising potential for biotechnological applications. Arthropod‐derived EV research remains relatively fragmented in contrast to the extensively studied mammalian EV field. In this review,

Generality of toxins in defensive symbiosis: Ribosome-inactivating proteins and defense against parasitic wasps in Drosophila.

PLoS Pathogens, 2017
While it has become increasingly clear that multicellular organisms often harbor microbial symbionts that protect their hosts against natural enemies, the mechanistic underpinnings underlying most defensive symbioses are largely unknown.

HowSpiroplasmaMight Swim [PDF]

Journal of Bacteriology, 2002
Spiroplasmas are small helical bacteria without rigid walls. They have a cytoskeleton in the form of a flat ribbon that runs the length of the cell. In an ordinary liquid medium, a cell spins about its long axis, but it does not translate. In a gel-like medium, containing a viscous agent like methylcellulose, it moves rapidly in a direction parallel to

Comparative genome analysis of Spiroplasma melliferum IPMB4A, a honeybee-associated bacterium

BMC Genomics, 2013
Background The genus Spiroplasma contains a group of helical, motile, and wall-less bacteria in the class Mollicutes. Similar to other members of this class, such as the animal-pathogenic Mycoplasma and the plant-pathogenic ‘Candidatus Phytoplasma’, all ...
