Species Cucurbita spp.
Crop Squash and pumpkin
Pest Scientific Name Cucumber green mottle mosaic virus (CGMMV)
Additional Info
Complementary Info
Type Virus
Pest Classification Is seed a pathway in this crop? Pathway not proven
Main literature references 8-11, 8-44, 8-46, 8-91, 8-94, 8-139, 8-163, 8-166
Remarks Cucurbita spp. are susceptible to GGMMV. It has been documented that seed is a pathway for CGMMV in cucumber, melon, watermelon and bottle gourd (Lagenaria). References suggest that seed is a pathway in squash, however, there are no references demonstrating seed as a pathway in squash. The virus is most prevalent in Asia. Seed productions in these areas should be routinely inspected for CGMMV.
Detection Is there a seed test? Yes
If yes, type of test Serological
Main literature references 8-42, 8-43, 8-45, 8-93, 8-183
Remarks An ELISA method exists and seed tests are available in some commercial labs. The validation experiment was carried out with a limited number of seed samples. It is strongly recommended that each user validate the performance of the technique to detect the virus under specific laboratory conditions. An ELISA method is an indirect method and often positive results are confirmed using a bioassay. One reference describes a PCR method to simultaneously detect a number of viruses. However, no positive and negative plant or seed controls were included in the evaluation of the PCR technique. In addition, the positive results of the multiplex PCR were not confirmed using a technique other than PCR.
Risk mitigation Can the pest be managed by seed treatment(s)? Yes
If yes, what type(s) Physical, Chemical (seed disinfection)
Main literature references 8-47, 8-48, 8-106, 8-191, 8-192
Remarks Dry heat treatment had been reported as a means to eliminate CGMMV from certain members of the Cucurbitaceae; melon and cucumber. See CGMMV entry under those crops for details. No references found indicating heat treatment has been tested in Cucurbita spp as a means of eliminating CGMMV from Cucurbita spp seed.
