Natural Infection of Squash Fruits by Zucchini Yellow Mosaic Virus ZYMV in Alexandria Governorate

Introduction: Zucchini Yellow Mosaic Virus (ZYMV) is a significant threat to cucurbit crops, particularly squash (Cucurbita pepo), causing economic losses worldwide. A recent study in Alexandria Governorate, Egypt, has investigated the natural infection of squash fruits by ZYMV, detailing its symptoms, transmission methods, and impact on crop health.

Key Findings:

• Virus Identification: ZYMV was isolated from naturally infected squash fruits showing mosaic, yellowing, blistering, and deformation.
• Transmission Methods:
  • Aphid Transmission: The virus was transmitted non-persistently by aphids, including Aphis gossypii, Aphis nerii, and Myzus persicae.
  • Mechanical Transmission: The virus was successfully transmitted through infected plant sap.
• Serological Testing: Indirect ELISA confirmed the presence of ZYMV in infected plants.
• Purification and Antiserum Production:
  • The virus was purified through ultracentrifugation and PEG precipitation.
  • Specific antiserum was developed with a high titer detected via ELISA.

Impact on Squash Cultivation: The study emphasizes the importance of early detection and integrated pest management to prevent the spread of ZYMV in squash crops. The American Phytopathological Society highlights the role of effective vector control in reducing viral infections in cucurbits.
