What exactly is a cucumber? Just follow me and see!
The cucumber is it
This insect does not have the body length of fireflies, and the cucumber has a wide range of feeding habits, which can harm 69 species of plants in 19 families. It harms almost all kinds of melons, the most severely affected are watermelons, pumpkins, melons, cucumbers, etc., but also harmful cruciferous, nightshade, legumes, sunflowers, citrus, peaches, pears, apples, trees and mulberry trees

It is a firefly
Fireflies are carnivores, preying on mollusks such as snails, slugs and earthworms, and it is not vegetarian! No vegetarian! There are many farmers and friends who have wronged it, and the leaves of vegetables such as loofahs, pumpkins, watermelons, and melons are not nibbled by it
It is a beneficial insect!
Cucumbers really look like fireflies, but there are still some differences in appearance
Fireflies are generally black, while adult yellow melons are orange-yellow or orange-red in color. And fireflies glow at night, but cucumbers don't have that ability. For farmers, this bug is very hateful, because it likes to eat the leaves of melon vegetables, and it is also one of the important pests of melon vegetables such as watermelon, melon, loofah, and pumpkin.
After being harmed by the cucumber, the melon seedlings were bitten like this in one day
"Yellow melon" is gregarious, phototropic, and likes to bite the same seedling together during the day
Let's take a look at how to prevent it
Although The yellow melon is small, it is very good at leaping, and when it is frightened, it will quickly fly away, or directly pretend to be dead. "Huang Shougua" encounters a little movement and pretends to die!
This kind of insect generally stays on the leaf to eat the leaf, and there is a strange phenomenon, that is, when they nibble on the leaf, they will rotate and bite with the radius of the body, so it will cause some semi-circular round holes on the leaf. If it is not prevented in time, the leaf will be eaten by it and there will be holes everywhere, which will affect the photosynthesis of the leaves.
Physical control
Scattering grass and wood ash method. Sprinkling grass and wood ash to prevent the bite effect of "cucumber" is very effective. However, it should be noted that the scattering of grass and wood ash must be in the morning, and it is sprinkled when the dew has not yet dried. Grass ash can be stained on the leaves. When the leaves are dry, the grass and wood ash cannot be stained. Sprinkle every once in a while, which can effectively reduce the leaves of the melon fruit from being eaten by the cucumber.
Artificial capture: If the area of the small farmer can be artificially captured, when there is dew in the morning, the "cucumber" activity is not sensitive, artificial capture, centralized destruction!
chemical control:
When the melon seedlings are relatively large, or in the nursery to find "yellow melon" can be used: avidinidium, thiamethia perchlorine fluoride, methyl vitamin perchlorofluoride, high efficiency chlorofluorothrin, and other cypermethrin sprays can be applied.
