How can I get rid of bee fly ( fly looks alike bee but smaller in size) is destroying all my cucumbers ?. What can I do for that . Some one suggested me the trappings, is that possible?
It sounds like Sweat Bees, that actually may be helping to pollinate your cucumbers.
You may want to look closer to see if you have another pest causing the damage.
Cucumber Beetles are one of several that can love to dine on your cucumbers.

In the last week my cucumbers have developed yellow spots on their leave that appear to be spreading quite quickly. They are being grown in a well ventilated greenhouse. Please see photo. Thank you, Alison Fraser
That is a fungal infection, and doesn't look like one that will be easily cured in an isolated container. This can happen when there is little drainage, and the soil is on the heavy side. It will naturally retain water, and only dry at the top, which will invite infection fairly quickly.
You can try wettable sulfur, but it may be too far spread already. Just make sure that when you are using container, you use a soil with quite a bit of perlite or any material that offers porous, high surface area for aeration.
Have bought two female cucumbers from a garden center. They look fine and small flowers have appeared. Do I need to buy a male plant? The label didn't say their name or if they were already pollinated. OR should I return to the garden center and ask them? Have read your information pages and I need bigger pots and I need to change the mixture of the compost. Thank you Kind regards Phyllis Handley
A cucumber plant produces both male and female flowers.

I would like to know what's wrong with my plants. I walked out into my container garden today and there were major spots and damages that were not there the day before. The weather is warm (up to the 90s and down to the 70s at night) and no rain has fallen in a while. The first picture is Straight 8 cucumber leaves in a self watering container. Obvious white and brown spotting on leaves. No insect damage that I could see. Second picture is from Brandywine tomatoes. Brown spots appeared on upper and mid leaves, smallish brown spots with darker brown around the edge. Can either of these problems be treated or are these plants toast? -Matthew
Hello,
Thank you for sending us your gardening question.
The cucumber appears to have powdery mildew, and the climate conditions that you describe would fit. This article may be of interest to you:

Yes, these are natural companions, and can provide trellising for cucumbers, while the cucumber provide a natural living mulch for asparagus.
