中国梨木虱在北京市平谷县果产区一年发生４～５ 代，以冬型成虫在树枝干裂缝内越冬，少量在杂草、落叶、土缝中越冬。１ 月底出蛰，２ 月中旬交尾，２ 月底３ 月初产第１ 代卵。第１ 代成虫５ 月上旬出现，第２ 代成虫６ 月中旬出现，以后世代重叠，９ 月上旬出现越冬代成虫。梨木虱发生和降水量有关，降水多则发生轻。防治上，清洁果园可杀死部分越冬成虫；越冬代成虫产卵前，是化学防治的一次关键时期；世代重叠后用０－９％ 爱福丁、２４－５％ 爱福丁、１－８％ 爱福丁防治效果好
Pear lice in China Pinggu County, Beijing fruit producing area occurs 4 to 5 generations a year, with winter-type adult winter cracks in the branches, a small amount of weeds, deciduous, soil cracks in winter. The end of January sting, mid-February to pay the end of February the first generation of eggs in March. The first generation of adult appeared in early May, the second generation of adults appeared in mid-June, later generations overlap, early September appeared overwintering adult. The occurrence of pear psylla is related to the precipitation, while the precipitation is less. Prevention and control, cleaning orchards can kill part of the overwintering adult; overwintering adult adults before spawning, is a key period of chemical control; generation after overlapping with 0-9% aphrodine, 24-5% % Avefort good control effect
