摘要
为明确北方茶园黑刺粉虱发生规律,2016年—2017年于山东烟台系统研究了日光温室盖保温被、日光温室及露地3种栽培模式茶园黑刺粉虱发生规律。结果表明,3种栽培模式茶园黑刺粉虱均以若虫在叶片背面越冬,1年发生4代,世代重叠严重。日光温室盖保温被栽培模式越冬代成虫羽化较日光温室和露地栽培发生早28 d左右,日光温室和露地栽培模式下黑刺粉虱发生期差异不显著。3种栽培模式茶园黑刺粉虱成虫全年均有4次发生高峰期,第1次高峰期日光温室盖保温被栽培模式较日光温室早20 d左右,日光温室较露地早30 d左右。黑刺粉虱发生量依次为日光温室>露地>日光温室盖保温被,均于10月上旬陆续以3龄若虫在叶片背面越冬。
To determine the occurrence regularity of Aleurocanthus spiniferus in northern tea plantations,the occurrence of A.spiniferus on three cultivation patterns,including sunlight greenhouse covering insulation quilt,sunlight greenhouse and open field,were investigated in Yantai during 2016-2017.The results showed that A.spiniferus under three cultivation patterns had four generations per year in Yantai,and it overwinters on the back of leaves with nymph.The eclosion of overwintering generation adults under sunlight greenhouse covering insulation quilt was about 28 days earlier than that under greenhouse and open field,without significant difference between sunlight greenhouse and open field.There were four peaks of adult occurrence in one year under the three cultivation patterns of tea plantations.The first peaks under sunlight greenhouse covering insulation quilt was about 20 days earlier than those under sunlight greenhouse,and the peaks under sunlight greenhouse was about 30 days earlier than that under open field.The occurrence number of A.spiniferus was ranked as follows:sunlight greenhouse>open field>sunlight greenhouse covering insulation quilt.A.spiniferus under the three cultivation patterns overwinters on the back of leaves with 3rd instar nymphs in early October.
