Today Xiaobian wants to tell you about an insect that can be artificially multiplied in large quantities, and it is also the nemesis of plant pests: the red-eyed bee!
Red-eyed wasp is a parasitic insect that can lay eggs in the eggs of pests, and as the eggs grow up, they will suck the nutrients in the eggs, causing the eggs to die, in order to achieve the purpose of controlling pests.
The use of red-eyed bees to control insect pests, whether from the perspective of environmental protection, efficiency, cost, etc., are relatively excellent, after testing, pesticide insecticides in the spraying into the field, 65% of the loss in the air and soil, 34% of the crops absorbed, the real can be used to kill pests only 1% of the pesticides, so to say, the use of pesticides to kill insects will not only cause damage to the environment, but also a lot of unnecessary waste in the morning, the insecticidal effect is also very general. After testing, the parasitic rate of eggs in the field after bee release can reach 70%-90%, so the treatment of insect pests is still very effective.
For example, in 1997, a forest farm in Hubei Province suddenly broke out the largest pine caterpillar infestation in history. In less than half a month, the wild spread of pine caterpillars ate the tender green pine needles, and the evergreen pine forest became a withered yellow. Because the forest farm area is too large, the trees are too high, and spraying pesticides is not realistic, so when the employees of the forest farm thought of using the red-eyed bee to control the method, they spent two days to hang the eggs of the red-eyed bee in the pine forest. The following year, the entire woodland was restored.
So what is the prospect of farmers breeding red-eyed bees?
Red-eyed bees have been used for the control of corn borer many times in China, and its main features are safe, effective and wide-ranging, and only a few bee egg bales per acre of land can effectively control pests. Many friends asked me, this red-eyed bee is so good, can we farmer friends raise it ourselves?
In fact, the current red-eyed bees are generally rarely farmed by farmers, generally by some professional organizations to breed, corn borer artificial breeding can be a large number of breeding in a short period of time, for a large area of pest control effect is very obvious, and our farmer friends want to breed their own words The most important thing is the prediction of corn borer, because the time to use the red-eyed bee is in the two months of the spawning period of the corn borer, generally the first generation of corn borers the first time to release bees at the end of May, the second time in early June, the interval of 5 days. The second generation of corn borers is released in late June or early July. Therefore, other times are basically not used, which involves the storage of insect eggs and other issues, so don't be blind! No professional set of predictions and breeding techniques will work!
Well, today's introduction is here, we are a science and technology farm, focusing on agricultural knowledge science, agricultural technology sharing and policy interpretation, like friends welcome to pay attention to us, your attention is our greatest encouragement!
