Abstract

• Illinois is the top pumpkin-producing state in the United States, growing ~90% of all processing pumpkins.

• Cucurbit Yellow Vine Disease (CYVD) causes substantial damage to important cucurbit crops, including pumpkin and squash.

• CYVD is caused by the Gram-negative bacterium Serratia ureilytica, producing yellowing and vine decline symptoms as well as fruit loss.

• The disease is transmitted by squash bugs (Anasa tristis), which are significant insect pests of many cucurbit crops.

• There is dispute whether transmission of S. ureilytica occurs through a circulative (in the hemolymph) or a non-circulative (within the digestive system) route within the insects.
