Green Vegetable Agricultural Biological Insecticides Farm Field Insect Killer Caterpillars Killing

Autographa californica nuclear polyhedrosis virus (AcNPV) is a microorganism that kills Spodoptera exigua. After spraying on crops and being eaten by pests, the virus particles replicate and multiply in the pest body, and quickly spread to all parts of the pest's body, drastically consuming insect tissues. During the period of "illness", the pests stop eating and moving, appearing a sub-lethal effect, and eventually die from dehydration. Spraying on eggs causes hatching larvae to die from feeding on virus-contaminated egg shells. Additionally, virus particles can continue to be transmitted to the next generation or other pests through the body fluids and feces of dead insects, providing long-term field pest control.
