华山松球蚜 (PineusarmandicolaZhang)是华山松 (PinusarmandiFranch)的重要食叶性害虫。本文以云南省昆明市东川区 2 2 2林场为研究试验点 ,对华山松球蚜的生物学特性进行了系统观察研究 ,首次发现了华山松球蚜的第一寄主丽江云杉 (Picealikiangensis (Franch .)E .Pritz .)和其有性世代。华山松球蚜有完整的生活周期即有有性世代 (以前研究者所观察到的华山松球蚜仅有无性世代 ) ,它在两种寄主华山松和丽江云杉上完成一个完整的生活周期。在有丽江云杉的情况下 ,华山松球蚜以伪干母产的一部份卵孵化的具翅性母飞到丽江云杉上 ,产生有性蚜。有性蚜两性生殖产卵孵化为干母 ,以 2～ 3龄若虫在丽江云杉叶鞘中越冬。干母产卵孵化的若虫在丽江云杉上取食形成虫瘿 ,并产生瘿蚜。虫瘿破裂后具翅瘿蚜又飞到华山松上产卵 ,产生伪干母 ,伪干母 2龄若虫在华山松叶鞘和树皮缝中越冬 ,完成完整的生活周期 ;在没有丽江云杉的情况下 ,华山松球蚜以伪干母产的另一部份卵孵化为留守型侨蚜在华山松上以孤雌生殖方式不断循环完成部分生活史 ,每年最多发生 6代 ,且世代重叠
PineusarmandicolaZhang is an important leaf-eating pest of Pinus armandiFranch. In this paper, we conducted a systematic observation on the biological characteristics of Pinus armandii (Pinus sylvestris var. Mongolica) in a 2222 forest farm in Dongchuan District, Kunming, Yunnan Province. It was the first time to discover the Picealikiangensis Franch.) E. Petz.) And its sexual generation. Huashan pine aphid has a complete life cycle that there is a sexual generation (previously observed by researchers Aphis Huashan only asexual generation), it is in the two host Huashan pine and Lijiang spruce to complete a complete life cycle . In the case of Lijiang spruce, Huashan pine aphid fly to the Lijiang spruce as part of the eggs of the pseudo-dry mother egg, produce sexual aphids. Sexual aphids hermaphroditism oviposition hatch dry mother to 2 to 3 instar nymphs in Lijiang spruce sheath winter. The nymphs hatched by the dry mother spawn on the spruce of Lijiang to form the gall and produce the aphids. After the break, the winged Aphis gossypii aphid flew to the Pinus armandii spawning, resulting in pseudo-dry mother, pseudo-dry mother 2nd instar nymphs in the Pinus armandii leaf sheath and bark stitches wintering, complete the complete life cycle; in the absence of Lijiang spruce , Huashan pine aphid hatching in another part of the pseudo-dry mother eggs for the living-type living aphids in the parthenogenetic cycle of parthenogenesis continue to complete part of the life history of up to 6 generations a year, and generational overlap
