Acaricidal Biominerals and Mode-of-Action Studies against Adult Blacklegged Ticks, Ixodes scapularis

MICROORGANISMS, 11(8).

By: G. Cave n, E. Richardson n, K. Chen n, D. Watson n & R. Roe n 

author keywords: mechanical insecticides; ticks; Imergard; Celite; repellency
TL;DR: Although the assumed mode of action of Imergard and Celite is dehydration, the minerals are not hygroscopic, there was no evidence of cuticle damage, and death occurred in as little as 2 h, suggesting minimal abrasive action of the cuticle. (via Semantic Scholar)

Biomolecular Minerals and Volcanic Glass Bio-Mimics to Control Adult Sand Flies, the Vector of Human Leishmania Protozoan Parasites

BIOMOLECULES, 13(8).

By: K. Chen n, J. Deguenon n, R. Lawrie n & R. Roe n 

author keywords: industrial biomolecular minerals; sand flies; Imergard; Celite
TL;DR: Proof of concept was established for the use of these biominerals for sand fly and leishmaniasis disease control and scanning electron microscopy of dead sand flies showed high coating levels of Celite only on the sides of the thorax and on the tarsi, suggesting an alternative mode of action for mechanical insecticides.

2022 review

Biology, Systematics, Microbiome, Pathogen Transmission and Control of Chiggers (Acari: Trombiculidae, Leeuwenhoekiidae) with Emphasis on the United States

[Review of ]. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH, 19(22).

By: K. Chen n, R. Roe n  & L. Ponnusamy n 

author keywords: chiggers; biology; systematics; microbiome; pathogen transmission; control
MeSH headings : Animals; Humans; Trombiculidae / microbiology; Scrub Typhus / epidemiology; Orientia tsutsugamushi; Acari; Microbiota; Biology
TL;DR: The role of chiggers in disease transmission in the US is especially understudied, and the role of endosymbionts in Orientia infection are suggested in the scientific literature but not confirmed. (via Semantic Scholar)

Internal and external microbiota of home-caught Anopheles coluzzii (Diptera: Culicidae) from Cote d'Ivoire, Africa: Mosquitoes are filthy

PLOS ONE, 17(12).

By: K. Chen n, L. Ponnusamy n , C. Mouhamadou n, B. Fodjo *, G. Sadia*, F. Affoue, J. Deguenon n, R. Roe  n

Ed(s): O. Terenius

MeSH headings : Animals; Humans; Anopheles / genetics; RNA, Ribosomal, 16S / genetics; Cote d'Ivoire; Malaria; Bacteria / genetics; Microbiota / genetics; Mosquito Vectors
TL;DR: The bacterial community of the external surface and internal body of female Anopheles coluzzii adults collected from homes in Côte d’Ivoire, Africa, is examined by Illumina sequencing of the V3 to V4 region of 16S rRNA gene. (via Semantic Scholar)

New thinking for filth fly control: residual, non-chemical wall spray from volcanic glass

MEDICAL AND VETERINARY ENTOMOLOGY, 35(3), 451–461.

By: K. Chen n, J. Deguenon n, G. Cave n, S. Denning n, M. Reiskind n , D. Watson n, D. Stewart, D. Gittins ...

author keywords: Grey flesh fly; house fly; Imergard&#8482; WP; mechanical insecticide; secondary screwworm
MeSH headings : Animals; Culicidae; Houseflies; Insecticides
TL;DR: These first studies on the use of Imergard WP against flies suggest this could be an alternative method for filth fly control, unlike that for mosquitoes where it was found mostly on the lower legs. (via Semantic Scholar)

By: J. Deguenon n, C. Riegel, E. Cloherty-Duvernay, K. Chen n, D. Stewart, B. Wang, D. Gittins, L. Tihomirov ...

author keywords: Imergard (TM) WP; mechanical insecticide; mosquito-borne disease; mosquitoes; residual spray
MeSH headings : Animals; Culicidae; Female; Insecticides; Minerals; Mosquito Control; Mosquito Vectors
TL;DR: This wettable powder made from volcanic rock is a mechanical insecticide representing a potential new mode of action different from current chemistry for mosquito control and is in commercial development under the trade name Imergard™WP as an indoor and outdoor residual spray.
