红蜘蛛的发生发展和生态因子的关系,早就为很多人注意,这当然是由于它的严重性所引起的。由于它分布广泛,为害寄主繁多,所以很早就引起了人们的研究,特别是探讨和研究它的发生消长规律。在国内一般却认为干旱的天气是红蜘蛛猖獗流行的决定因素。事实上,红蜘蛛对大气中的温湿度反应也确为灵敏,尤其在为害盛期,与出口密度的下降关系上表现的更为突出,这都为前人所证实。不少资料报导温度在27℃以上、湿度在50%以下最适其繁殖。 The relationship between the occurrence and development of spider mites and ecological factors has long been paid attention to by many people, which is of course caused by its seriousness. Because of its wide distribution, damage to the host a wide range, so early aroused people’s research, especially to explore and study its occurrence and decline of the law. In the country, it is generally considered that the drought weather is a decisive factor in the rampant popularity of spider mites. In fact, the spider mite on the temperature and humidity in the atmosphere is also very sensitive to the reaction, especially in the peak period, the decline in export density and more prominent relationship, which are confirmed by our predecessors. A lot of information reported that the temperature above 27 ℃, the humidity below 50% of the most suitable breeding.
