Hello everyone, I am Elder Tang, a senior meat friend who has raised succulents for more than 6 years, and today a meat friend asked: The succulent evergreen insects have gnawed a hole in the young buds, and the leaves have fallen off, what methods can be used to prevent it?
Fire sacrifice out of state
Although succulent dew culture is easy to color out of the state, but the spring, summer and autumn three seasons of Xuanfei butterfly is a lingering nightmare, because they not only have a long activity time, from April to May to activity until the end of October, and the harm is great, the larvae will burrow into the succulent leaves and stems after hatching, in the leaf nibbling at the same time, but also cause succulent direct death. What's even more frightening is that they not only come to lay their eggs themselves, but also call relatives and friends to come together, and completely use our exposed succulents as a cafeteria!

Many meat friends think that the larvae are only green and hidden in succulent leaves or stalks, but this is not the case, they are very intelligent, not only will they turn brown for camouflage, but also move to the soil to hide. I used to have a pot of Ensino leaves always been chewed off, I thought it was slugs or snails, but I didn't see the traces left by the crawl, so I went to squat for several days, and finally found a fat bug drilling out of the pot soil one evening, and as soon as I touched the pot it immediately retracted. Of course, as long as I found its traces, I would definitely not be able to run, so I directly turned over the flowerpot, and then caught it out and stomped on it fiercely, and finally solved the hatred in my heart.

In the process of succulent maintenance, if we find that there are fresh holes in its leaves or stems, and there is a pile of black insect feces around, it is the Xuanfei butterfly larvae that are tricking the ghost, we must break the leaves, or break the stems, and then find out the insects to destroy, otherwise it will grow bigger and bigger, and the amount of food will be larger and larger, and then it will not be long before the whole succulent will be gnawed by it.

If you really can't find bugs, we can spray some insecticides, such as avermectin and imidacloprid, etc., which have a very good killing effect on butterfly larvae, even if the bugs are too big to kill directly, they will automatically run out, and curl up on the soil surface of the pot, we can directly kill them. If the number of succulents is not large, there are only a few pots or a dozen pots, we can also simply make an insect net, so that the butterfly cannot lay eggs on the succulent leaves.

Of course, the best way to deal with Xuanfei butterfly larvae is to directly use small purple medicine and other inhalation insecticides, sprinkle the succulent and then water it to absorb, not only can most of the insect eggs of Xuanfei butterfly not hatch, but even if they hatch, they will be poisoned, and at the same time can prevent and control mesophylls. However, what medicine is not omnipotent, even if the small purple medicine is released, occasionally there are a few Xuanfei butterfly eggs that become fish that slip through the net and will successfully hatch, and we found that the succulent leaves are nibbled in time to find out and destroy them.
