virus
Korea, Mexico
Main: Cucurbitaceae family. Also infects Amaranthaceae, Apiaceae, Chenopodiaceae, Fabaceae, and Hydrophyllaceae
SQMV00
Squash mosaic virus is transmitted by numerous insect species, mostly beetles. Seed is also a pathway for certain species.
5 Known Hosts
Citrullus lanatus
watermelon
uncertain
SQMV00-10, SQMV00-9, CABI CPC, DPV WEB
No field observations of squash mosaic virus in watermelon. Watermelon infection by squash mosaic virus only an experimental curiosity and not found in nature.
yes
ELISA and grow out
This method is the standard method of the NSHS.
ELISA, positive confirmation by Grow out is the standard method of the NSHS.
NSHS USDA
Chemical, cultural
Insecticides to control beetle populations can reduce spread. Remove infected seedlings. Use disease-free seed.

Cucubita pepo
squash, gourd
uncertain
SQMV00-10, SQMV00-9, DPV WEB
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
ELISA, Grow out
Though seed is not known to be a pathway in squash, commercial testing is sometimes offered. This is the standard method of the NSHS.
ELISA, positive confirmation by Grow out is the standard method of the NSHS

Cucumis melo
melon
Yes
SQMV00-10, SQMV00-2, SQMV00-3, SQMV00-9, CABI CPC
Seed transmission in Cucumis melo is well documented and accepted. Melons are the most economically effected crop.
Yes
ELISA, Grow out
This method is the standard method of the NSHS.

Cucumis sativus
cucumber
No
SQMV00-10
There is no evidence that cucumber seed is a pathway for this virus.
Though seed is not a pathway, commercial testing is available using the NSHS standard ELISA and grow-out confirmation.

Cucurbita spp.
pumpkin
Yes
SQMV00-10, SQMV00-9, CABI CPC, DPV WEB
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
ELISA, Grow out
This is the standard method of the NSHS.
