Cucumber striped beetle is a vector of Bacterial wilt.
Adults feed on flowers, leaves and fruit, but focus their feeding on the undersides of developing fruit during warm periods. Feeding on flowers and leaves may result in severe defoliation, whereas feeding on fruit produces scarring damage that directly reduces yield.
In addition to direct feeding damage, the striped cucumber beetle (along with the spotted cucumber beetle) is the primary vector of bacterial wilt disease in cucurbits, caused by the pathogen Erwinia tracheiphila.

Plants that need two seasons to complete their vegetative and reproductive growth are called Biennials.
Biennials are plants that complete their life cycle in two growing seasons. During the first growing season, biennials produce roots, stems and leaves; during the second they produce flowers, fruits and seeds, and then die.
Biennials grown for flowers, fruits or seeds need to be grown for two years. Biennials that are grown for edible leaves or roots are grown for just one year
`Eg: Silverbeet, Black-eyed Susan, Sweet William, colic weed, carrot, etc.

Yeast is employed in the preparation of Wine.
The role of yeast in winemaking is the most important element that distinguishes wine from fruit juice. In the absence of oxygen, yeast converts the sugars of the fruit into alcohol and carbon dioxide through the process of fermentation.
The more sugars in the grapes, the higher the potential alcohol level of the wine if the yeast is allowed to carry out fermentation to dryness.
