Living habits occur throughout the country, occur 2 generations a year, and spend the winter on bush branches. During the April-May period of late spring eclosion, the first generation of larvae occurred from May to June, adults emerged from June to July, and second generation larvae occurred from July to August. Eggs are scattered on the leaf surface. The larvae feed on nocturnal movements, and when they are touched, they come out of the chest with a foul horn (glandular glands) and exudate odor.
When sporadic control methods occur, control measures may not be taken separately. When there is a large amount, common insecticides are sprayed on young larvae.
Antibiotic: A drug used to treat bacterial infections. Antibiotics have no effect on viral infections. Originally, an antibiotic was a substance produced by one microorganism that selectively inhibits the growth of another. Synthetic antibiotics, usually chemically related to natural antibiotics, have since been produced that accomplish comparable tasks.
Antimicrobial: A drug used to treat a microbial infection(antibiotic drugs).
"Antimicrobial" is a general term that refers to a group of drugs that includes antibiotics, antifungals, antiprotozoals, and antivirals.
