Pesticide weeding and pest control in spring beware of bee pesticide poisoning

Bee poisoning symptoms: the sudden death of a large number of bees, the stronger the group, the more dead bees, and most of the dead bees are gathering bees, often with pollen balls on their legs. The swarm is restless, chaotic and often stings. During the spleen lift examination, more bees will fall to the bottom of the box because they are unable to attach to the spleen. At the door of the nest, poisoned bees can be seen rolling and spinning on the ground, and their bodies are constantly twitching and convulsing. Dead bees often spread their wings, bend their bellies, and kiss out. In serious cases, the larvae in the box also die, and the poisoned larvae often come out of the nest, resulting in the phenomenon of "jumping". Sometimes the worker bees "besieged the king", causing a sharp decline in the situation of the group, and even caused the whole group to be destroyed. Bee colony pesticide poisoning is mainly for prevention, and those who have been poisoned should be rescued immediately. The method is:

Release bees

1. Bees, whether fixed or transferred, must keep a certain distance from honey plants, usually 100-200 meters, when placing bees, which can reduce the chance that bees will encounter pesticides and liquid into the beehive as soon as they leave the hive.

2. In the process of releasing bees, we should understand and master the drug use habits and methods of crop and fruit tree planting units or farmers in the corresponding range, and contact them actively. The benefits are as follows: first, the application of pesticides during flowering can be avoided; second, if drugs must be used during flowering, strive to make the other party use low toxicity and water agents as much as possible, and use less high toxicity and powders. In terms of time, avoid spraying at noon and set the time in the morning when the bees do not leave the nest or in the evening when the bees return to the nest; third, under the premise of not affecting the efficacy and damaging crops, add appropriate amount of repellent such as carbolic acid, coal tar (add a small amount of soap) and so on.

3. During the spraying period, the bees can be temporarily moved or claustrophobic according to the residual period and toxicity of the pesticide (the time should not be too long), and the honey should not be shaken before spraying to keep the honey source in the box adequate. During the application, water is often sprayed into the hive to reduce the number of bees leaving the hive and reduce toxicity.

4. When the colony has been affected by pesticides, remove all the mixed poison feed in the colony, at the same time, widen the bee road to ventilation, and feed 1:1 thin syrup. Then, according to the toxicity and classification of pesticides, the antidotes are given appropriately. For bees poisoned by organophosphorus pesticides such as 1605, 1059, trichlorfon, dimethoate and other organophosphorus pesticides, 0.05-0.1% atropine sulfate or 0.1-0.2% phosphate solution can be used for spleen spray and detoxification; for bees poisoned by organochlorine pesticides such as triclofenac sulfone, mung bean, licorice, 50 grams of honeysuckle and 2000 grams of fried juice can be used to spray spleen. At the same time, those besieged by pesticide poisoning should be sprayed with warm water or honey water in time.
