| 【目的】研究绿盲蝽越冬卵的分布及其孵化规律，为掌握绿盲蝽卵的防治时间、防治地点以及制定防治措施提供依据。【方法】分别选取沧县高川乡朴寺村和盐山县城关镇的纯枣园及苹果 梨 枣混合枣园，调查2类枣园绿盲蝽越冬卵的分布情况，并将越冬卵带回室内饲养观察其孵化规律。【结果】在纯枣园，绿盲蝽卵的越冬场所主要为夏剪剪口、多年生枣股和其他伤口；在杂草、农作物残留物、1年生枣股以及土壤中未发现绿盲蝽越冬卵的分布。在枣 梨 苹果混合枣园，越冬卵在枣树上分布最多，占总卵量的50.40%，其次为苹果和梨树，越冬卵分别为总卵量的35.29%和14.31%。4月份采集的绿盲蝽越冬卵的孵化率最高，其孵化率达到87%以上，与其他月份采集卵的孵化率有极显著差异；绿盲蝽越冬卵的孵化盛期在4月末至5月初，此时枣芽长度一般为2～3 cm。【结论】绿盲蝽越冬卵主要集中分布在枣树的夏剪剪口和其他伤口,在杂草、农作物残留物、1年生枣股以及土壤中无分布，其孵化盛期在4月末至5月初。 |

| Abstract: |
| 【Objective】The study was about the distribution and hatching regulation of the overwintering eggs of L.lucorum in order to provide scientific basis for the time,the place and the method of prevention and control.【Method】We surveyed overwintering eggs in jujube orchard and orchard that comprised apple,pear and jujube in Pu Si village,Cang Zhou,He Bei and Yan Shan.【Result】The result showed that L.lucorum laid eggs in the summer pruning wounds,perennial dates and other wound,and no eggs were found in weeds,residues of crops,one-year mother spur of jujube and soil.The overwintering eggs most widespread in jujube with a proportion of 50.40%,in apple and pear with a proportion of 35.29%,14.31% respectively.The eggs collected in April had a high hatching rate of 87% which was extremely significantly different form other months;When the lenth of jujube bud was 2-3 cm,the number of hatched eggs was close to the peak value,which was between the end of April and the beginning of May.【Conclusion】The L.lucorum laid eggs in the summer pruning wounds,perennial dates and other wound,and no eggs were found in weeds,residues of crops,one-year mother spur of jujube and soil.The number of hatched eggs was close to the peak value,which was between the end of April and the beginning of May. |
