Pharmacy and insect parts easily penetrate easily poisoned: Pharmacy invading parts of the brain and nerve from the closer, the more rapid intoxication. Instar larvae of different agents into the different speeds of Zhoukou 5% granules acre of land, the young larvae are just off the wall and through the skin of the larvae, pharmaceutical easy invasion. Larvae before peeling Shanghai 5 percent an acre of land granules, peeling skin between the old solution (containing various enzymes), not through agents. Thus, when pesticides for toxicity determination, to choose just off the skin off 3-4 instar larvae. Stomach poisoning stomach poison should have the conditions: Insect eating the meat without causing vomiting or diarrhea: Luoyang 5% due to insect vomiting acre of land granules, diarrhea is a way of self-detoxification, can reduce the stomach toxicity effect, if a cutworm larvae baits containing MSMA after 5% granules acre of land, due to the contraction of the intestinal muscles and stop feeding. Would have been swallowed bait vomited, while stimulating gastrointestinal endocrine fluid increased. In the digestive tract into a watery-like baits excreted within pyrethroid pesticides on most insects vomiting. Noctuidae larvae inorganic pesticides also have vomiting.
