Latest Corn Borer Control Technique: How to Use Trichogramma Wasps?
There are many species of Trichogramma wasps in nature. The Trichogramma species currently used to control the corn borer is Trichogramma dendrolimi. Generally, at the beginning of the adult corn borer's egg-laying period, Trichogramma wasps are artificially released into the field so that they lay their eggs inside the corn borer eggs, preventing the eggs from hatching into larvae.

What are the causes of corn borer outbreaks?
What are the causes of corn borer outbreaks? Please explain. The causes of corn borer outbreaks are as follows: (1) Insect population base: the size of the insect population base from the previous generation is an important factor affecting the severity of corn borer damage. A large insect population base, under suitable environmental conditions, often causes severe damage. ...

How should corn borers be controlled? A detailed explanation of control methods
How should corn borers be controlled properly? Please explain the methods. Corn borers can be controlled by referring to the following methods: Controlling corn borers at the corn whorl stage: for fields with a damaged-leaf rate of 10%, carry out full treatment at the end of the whorl stage; where the damaged-leaf rate is below 10%, selective treatment may be done as appropriate; where the damaged-leaf rate exceeds 20% or there are more than 30 egg masses per 100 plants, treat once at the mid-whorl stage and once at the end of the whorl stage respectively...

What are the control methods for corn borers?
How to control corn borers? Please explain the methods. Corn borers (corn borer) are a major pest of corn. In years with severe infestation, they can reduce corn yields by more than 20%. Their larvae bore into the main stalk and ears, which can break the main stalk of corn, causing reduced yield and quality. In the past, controlling corn borers mostly used methods such as pouring pesticide solution into the whorl, spraying, or applying poisoned soil into the whorl, which was labor-intensive and ineffective, and easily caused crop damage and human and livestock poisoning. Using granule formulations to control corn borers not only has low cost, saves labor, and is effective, but also is unlikely to cause human and livestock poisoning or crop damage. The following points should be mastered:
