冬天,苍蝇躲到又暖又脏的地方不再飞;蛆也变成蛹在土里“睡觉”。春天一到,气温回升,蛹很快钻出土变成蝇;气温25℃时,成蝇就能交配产卵,大量繁殖了。在天气转暖之前,因为蝇蛆数量少,活动能力也小,消灭它们容易,而且大大减少天热后成蝇。因此,抓住天气转暖前的时机,结合春季积肥,大搞灭蝇,是消灭 In winter, flies hid in warm, dirty places and no longer fly; maggots also become pupae in the soil, “sleep.” When the spring is over, the temperature rises, and pupae soon become unearthed. When the temperature is 25 ℃, adult flies can mate and spawn and multiply. Before the weather gets warmer, because of the small number of maggots and their low mobility, they are easy to eliminate and greatly reduce the incidence of heat into an adult. Therefore, to seize the opportunity before the weather warmer, combined with the spring fertilizer, fly fierce fight is to eliminate
