SQMV00
Spread by Diabrotica beetles
5 Known Hosts
Cucumis melo
melon
Yes
SQMV00-2,SQMV00-3,SQMV00-9,SQMV00-10
Seed transmission in Cucumis melo is well documented and accepted. Melons are the most economically effected crop.
Yes
ELISA, Grow out
ELISA, positive confirmation by Grow out is the standard method of the NSHS

Citrullus lanatus
watermelon
No
SQMV00-9,SQMV00-10
Pathway not proven. No field observations of squash mosaic virus in watermelon. Watermelon infection by squash mosaic virus only an experimental curiosity and not found in nature.
Cucumis sativus
cucumber
No
SQMV00-10
There is no evidence that cucumber seed is a pathway for this virus.

Cucurbita spp.
pumpkin
Yes
SQMV00-10,SQMV00-9
Seed transmission in pumpkin is known to occur, though infrequently. It is not clear if seed from pumpkin varieties of C pepo can be a pathway or if seed transmission is in other pumpkin species.
Yes

Cucubita pepo
squash, gourd
No
SQMV00-10,SQMV00-9
Seed transmission in squash has only been shown in plants artificially inoculated with the virus. Natural outbreaks due to seed transmission have not been reported in squash. No references found indicating seed is a pathway in gourd.
Yes
