Can this plant be brought indoors for the winter? Is it to be treated the same as Mandevilla?
Yes, these are pretty much the same thing so treat them as such. Bring the plant indoors prior to your frist frost and allow it to go dormant. It will only need watering once a month during dormancy to keep the plant from drying out completely. Once spring returns and new growth begins, you can move it back outdoors (after threat of frost) and care as usual.
Yes, you can bring your Dipladenia indoors for winter. 🌿 It prefers bright, indirect light, so place it near a sunny window. Water sparingly, allowing the top inch of soil to dry out between waterings. Dipladenia is similar to Mandevilla in care but is more compact and may need less pruning. This will help it thrive indoors until spring.
Will dipladenia survive winter outside? Thank you.
I'm sorry, but I cannot approve answers written by AI. It gets information VERY wrong, sometimes.

Dipladenia is a tropical plant, hardy only to zone9 - that is, it can take a few days of freezing to slightly below freezing, but in general it should not be kept below 40 F (4.5 C).

How much sun does the Dipladenia need? Can I plant them in flower beds? Or do they do better in pots?
Dipladenia is perennial, rated for USDA plant hardiness zones 9-11. Dipladenia prefer bright but indirect sun. Given that your planting zone is 6a you will probably want to pursue dipladenia as a potted plant. You can situate your potted plant outdoors until temperatures dip below 60 degrees.

How high does a dipladenia mandevilla grow?
3 to 10 feet.
If it's a container plant it will not reach as tall of a height as if it was planted in the ground.

Just bought, it's about four feet tall in excellent conditions with plenty of flowers and new buds. Can I keep it in my conservatory? It's got plenty of daylight and the sun comes round in the afternoon. How long should it flower?
This should be an excellent spot to grow your new plant.

I have a dipladenia that I bought this summer and plan on overwintering indoors (zone 7). There are some very small bugs on the tips, yellow in color and I don't really want to bring them indoors. What should I do to get rid of them before I bring it inside?
Those yellow bugs are probably oleander aphids. Here is an article that will give you ideas on how to contend with them - Horticultural soap sprays or neem oil work well for aphid control.:
