1. Whether the fly can complete its life cycle is largely dependent on climatic conditions. When the temperature is lower than 15°C or higher than 45°C, and the humidity is lower than 60% or higher than 80%, it can well inhibit the growth of flies. The movement of flies is greatly affected by temperature. It can only crawl at 4~7℃, and can fly at 10~15℃. It can eat, mate, and lay eggs above 20℃. It is especially active at 30~35℃, and stops at 35~40℃ due to overheating. 45~ Lethal at 47°C. In the entire flies population, 80% are in the developmental stage, and only 20% are adult flies. Therefore, in April, flies can be controlled in the larval stage.

 

2. Prevention and control of flies

(1) Physical prevention and control of flies

Clean up the manure in time, and pay special attention to the manure and sewage in the dead corners, and keep the pig house as dry as possible; timely and properly handle the sick and dead pigs; clean up the waste litter in time; regularly check the drinking water and feeding system to ensure that there is no leakage or sprinkling . And according to the situation of the pig farm, equipment and equipment can be installed in the pig house and the canteen of the pig farm.

 

(2) Chemical control of flies

In the entire population of flies, 80% of the population are larvae in the developmental stage, and only 20% are adult flies. Therefore, the control of flies is divided into two parts: adult flies and larvae:

For adult flies: Use fenvalerate (deltamethrin) + dichlorvos to quickly reduce the density of adult flies.

 

For eggs, pupae, larvae: to eliminate eggs (for eggs in dung piles, floors, dung drains, sewers, railings, walls, etc.), how to use them

Note: It can be used continuously in high temperature and high humidity seasons, and can be doubled. Note that the maximum dosage is 400 g/ton material, and it has been used in a large area in the south of China.
