摘 要:1996~1998年在香港连续3年利用荔蝽卵平腹小蜂防治荔蝽,1996年4月调查,放蜂的3个类型区卵块寄生率分别达80.00%、89.57%和90.00%,卵粒寄生率分别为81.81%、68.72%和89.16%;而对照区的卵块寄生率和卵粒寄生率仅分别为16.67%和17.07%。1998年5月调查,放蜂的各类型区卵块寄生率和卵粒寄生率均分别达到100%和99%以上;对照区的卵块寄生率和卵粒寄生率也分别高达87.50%和87.96%。同时,果园虫口密度显著降低。Satisfactory results were obtained in using Anastatus japonicus to control litchi stink bug (Tessaratoma papillosa)in Kadoorie Farm & Botanic Garden in Hong Kong 1996 ̄1998 The percentages of parasitized egg mass were 8000%, 8957% and 9000% respectively and the percentages of parasitized eggs were 8181%, 6872% and 8916% respectively in three orchards of different elevation in 1996 The percentage of parasitized egg mass was only 16.67%, and the percentage of parasitized eggs was only 1707% in the check. When the orchards, A. japonicus had been released, were examined in 1998, the bug populations were reduced significantly Practically all the eggs of the litchi stink bug in different elevations were parasitized, and even in the check plots the percentage of parasitism reached 87%, probably due to the dispersion of the wasps from the released plots
