What are the methods for farming corn worms? This article is all you need

Corn worms often appear in crops such as corn, and they are dark yellow all over. Below we introduce the methods for farming corn worms.

1. Methods for farming corn worms

When farming corn worms, generally keeping the temperature at 20 to 40 degrees allows normal growth and reproduction. Feed them corn stalks. Each female worm can lay 1000 eggs. Corn worms usually appear in items such as rice, corn, and distiller's yeast.

2. What are the consequences of accidentally eating corn worms?

Corn worms themselves do not contain harmful substances and will not cause harm to the body. The main tissue component of corn worms is also protein. After being accidentally eaten and entering the digestive tract, they will also be decomposed and metabolized into carbohydrates, amino acids, trace elements, and so on.

3. Control techniques for corn borers

1. Using Trichogramma to destroy eggs

Release Trichogramma ostriniae or Trichogramma dendrolimi 3 times at the beginning, early peak, and peak of corn borer egg laying, releasing 150,000-300,000 insects per hm2 each time, with 75-150 release points per hm2. When releasing the wasps, after the wasp cards have been acclimated to variable temperatures, clip them in the leaf axils of the fifth or sixth leaf from the bottom of the corn plant.

2. Using Beauveria bassiana to control borers

At the heart leaf stage, mix Beauveria bassiana containing 5 billion-10 billion conidia per gram with slag granules at 10-20 times the amount, and sprinkle it into the heart leaf cluster, 2g per plant. Alternatively, in spring, after the overwintering larvae revive and before pupation, pile up the remaining corn stalks and spray the Beauveria bassiana powder produced by traditional methods at 100-150g/m3 layer by layer inside the stalk stack to seal the stack.

3. Using Bacillus thuringiensis to control borers

Bacillus thuringiensis varieties, Galleria mellonella varieties, and kurstaki varieties have strong pathogenicity against corn borers. Industrial products are mixed with granules to form granules containing 100 million-200 million spores per gram, and sprinkled into the heart leaf cluster at the end of the heart leaf, 2g per plant, or use BT bacterial powder 750/hm2 diluted 2000 times to irrigate the heart. For control at the ear stage, drip-irrigate Bt 200-300 times dilution on the silks of the female ear.

The above is the relevant information about corn worms. We hope it is helpful to everyone.
