Cucumber beetles that get their name from the cucumber plants that they feed on are either a striped or spotted species.
Both species feed on the flowers, fruits, and leaves of the cucumber, pumpkin, and squash plants. When available, they will also feed on beans, corn, and potatoes.
Adult cucumber beetles grow to be ¼ inches in length and are yellow to green in color with a dark head and spots or stripes on their wings. Adults feed on seedlings, foliage, flowers, and pollen of the plants, destroying them as they do.
The young larvae of the cucumber beetle can grow up to ⅓ in length and are white in color. They feed on the roots and stems of the plants.
Both the adult and their larvae can transmit diseases that include bacterial wilt and mosaic virus to cucumber plants.
Female beetles begin laying their eggs in early spring, be posting up to 800 at a time in the soil near the plant's base. After 10 days larvae emerge, then feed for four weeks until their pupate stage begins. Another 10 days is all that is needed before an adult cucumber beetle emerges and starts the reproduction and feeding process again.
Controlling cucumber beetles and their youth is a must before a heavy infestation begins. Check plants often for the beetles and their larvae, then pick them off and drop them into a container of warm soapy water for easy disposal.
Invest in floating row covers and place on seedlings until they begin to mature to prevent the beetles from feeding on the plants.
Incorporating beneficial bugs who feed on the pests' eggs, such as green lacewing, lady beetles (ladybugs) and spine soldier bugs can help reduce the beetles.
Beneficial nematodes introduced into your garden's soil can prevent immature stages of the cucumber beetle's young from developing.
Even after taking so much care of the cucumber tree, even after using many pesticides, I could not destroy the insects, I hope I can destroy the insects of the cucumber tree by following the method given by you,
