| 中文摘要: |
| 为明确桑蓟马对桑树品种的趋性及发生规律，采用蓝色粘虫板诱捕法调查了桑蓟马在桑树湖桑 32 号、云桑 2 号和农桑 14 号的发生情况。 结果表明，3 个桑树品种桑蓟马发生量的顺序为湖桑 32 号跃云桑 2 号跃农桑14 号，湖桑 32 号的每板虫量显著高于云桑 2 号和农桑 14 号；桑蓟马种群从 2 月至 4 月迅速增加，其大发生主要集中在 4~5月，桑树夏伐后其种群数量降低，湿度可能是其种群消长的重要因素，相对湿度为 50%左右时有利于其大发生。 因此，桑蓟马更趋向于湖桑 32 号，在相对湿度较低季节，应重视桑蓟马的防治。 |
| 英文摘要: |
| Investigated the population of Pseudodendrothrips mori in Husang-32, Yunsang-2 and Nongsang-14 by the blue sticky cards, aimed to understand the host preference and occurrence dynamic of P. mori. The result indicated that the volume occurred of mulberry thrips was in the sequence of Husang-32 Yunsang-2 Nongsang-14, and trap catches of Husang-32 were significantly higher than those Yunsang-2 and Nongsang-14. The population of P. mori increased from February to April, and the outbreak period was April to May, and decreased after summer cutting of mulberry. Humidity was an important factor in the population dynamics of P. mori, and there was favor to outbreak at the relative humidity about 50%. Therefore, mulberry thrips were preference to Husang-32. Thus, at low relative humidity season, more attentions should bepaid to the mulberry thrips control. |
