摘要
在受害白榆植株上观察红足壮异蝽生物学特性,结果表明:在集安市气候条件下1 a发生1代,以成虫越冬;5月中旬成虫进行交配,约10 d左右开始产卵,卵期约15 d;6月中旬卵开始孵化,7月上旬为孵化高峰期;若虫共脱皮5次,历期约为60 d;8月中旬若虫开始羽化为成虫,9月上旬为羽化盛期;10月下旬全部进入越冬状态。可捕杀交配期成虫和卵,或在若虫初期喷洒10%吡虫啉2 000倍液、1.2%苦参碱乳油1 000倍液等进行防治。
The biological characteristics of Urochela quadrinotata was observed on the affected Ulmus pumila plant.The re-sult showed that one generation occured for one year in the climate condition of Ji’ an city and adult overwintering.The a-dult mated in the middle of May.It began to spawn through 10 days and last 15 days.The spawns began to incubate in the middle of June.It reached the peak early in July.Nymph went through decrustation for 5 times about 60 days.Nymph be-came adult after eclosion in the middle of August.The peak of eclosion was early in September.It entered overwintering completely late October.The control can be carried by catching adult and spawn in mating season or spray 10%imidaclo-prid 2 000 times diluent in the initial stage of nymph, 1.2%sophocarpidine missible oil 1 000 times diluent.
