Its optimum temperature for it was 20~25 °C. It had very high survival rate at 2 °C.The survive, development and reproduction of the mite varied with photoperiod. The development could not complete in darkness, but the eclosion of eggs was normal. The highest survival rate from egg to adult mite was in a photoperiod of ≥12 h. The shortest period (13 91 d) from young mite to adult female mite was in a photoperiod of 8 h and the longest period (32 33 d) was in 5 h .In the photoperiod of 8 h,≥12 h, the female mite could oviposit normally and the quantity of eggs were 9 13 and 12 67,respectively .The adult female could not oviposit and had the shortest longevity (10 d) in a photoperiod of 5 h.展开更多
首次研究南京地区竹锈褐斑病,确定了在南京地区的病原主要为南京裂爪螨Schicotetranychus nanjingensis Ma et Yun,同时伴有竹裂爪螨Schicotetranychus yoshimekii Ehara危害。对南京裂爪螨进行了生物学特性观察并建立特定年龄生命表...首次研究南京地区竹锈褐斑病,确定了在南京地区的病原主要为南京裂爪螨Schicotetranychus nanjingensis Ma et Yun,同时伴有竹裂爪螨Schicotetranychus yoshimekii Ehara危害。对南京裂爪螨进行了生物学特性观察并建立特定年龄生命表。该螨在南京地区3月上旬出蜇,11月上旬以卵和雌成螨越冬。生活史分为5个阶段:卵-幼螨-前若螨-后若螨-成螨,不同温度对南京裂爪螨各虫态的生长发育和存活率都有不同程度的影响,20—32℃是南京裂爪螨生长的适温区。展开更多
