| 摘 要： | 在江西南昌观察结果表明:梨茎蜂的发生为害与气象条件及梨树抽梢长度有很大关系。在3月底~4月初,当连续晴天、日最高气温在20℃以上时,成虫开始出枝为害,为害期6~8 d。当梨树新梢长度为8~12 cm时,成虫产卵达高峰期,此时为害最严重。

| Abstract: | The results of observation in Nanchang of Jiangxi province showed that the occurrence and harm of Janus piri had great relations with the meteorological condition and the new branch length of the pear.The adults began to harm the pear when it was sunshiny and the highest temperature was above 20 ℃ from the ending of March to the beginning of April,and the harm period was 6~8 days.The oviposition of Janus piri reached fastigium when the length of new branch was 8~12 cm,and it was the most harmful time. |
