Problem with my cucumber plants

The leaves of the cucumber plants become white and then brown-yellow in color. Fruits are bending. Also, some insects are eating the leaf surface. Please provide some control measure.

The red insect on the second image could be a Flea beetle or cucumber beetle. They feed on leaves by making small holes or pits that give the foliage a characteristic “shot hole” appearance. I believe the infestation is low. It can be managed by the application of a thick layer of mulch which prevents beetles reaching the surface and/ apply diamotecoeus earth or neem oil.

Bending or curling of fruits may occur due to various reasons like
1. Poor pollination
2. Variation in temperature (very high or low) during pollination and/ fruit development.
3. Nutritional imbalance
4. Fluctuation in soil moisture.
5. Damage due to insect pests (particularly from sucking insects like aphids, thrips, whiteflies etc.)

Samarendra, your last image looks like leaf miner damage. Leaf miners are not usually threatening to plants, but control can be needed to manage the really pronounced tunnels in leaves that can reduce crop health.
-Monitor plant leaves closely. At the first sign of tunneling, squeeze the leaf at the tunnel between two fingers to crush any larvae. Pick off and destroy badly infested leaves in small gardens.
-Make sure to maintain plant health with organic fertilizers and proper watering to allow plants to handle pest damage.
-Use yellow sticky traps to catch egg laying adults. Cover soil under infested plants with plastic mulches to prevent larvae from reaching the ground and pupating.
-Organic neem oil will break the pests’ life-cycle by preventing larva from reaching maturity. Neem oil may also have repellent qualities and interfere with egg laying activities. (https://www.planetnatural.com/pest-pr...)
