Abstract

里山と都市緑地におけるマイマイガ<i>Lymantria dispar</i> L.の寄生性天敵相の違いを知るために,大阪府能勢町の三草山と堺市の大阪府立大学構内(府大構内)を調査地として,1997年5∼7月にマイマイガ幼虫を採集し,個別飼育を行うことにより,脱出する寄生者を記録した.<br>三草山ではマイマイガ幼虫の21%から,府大構内では31%から,それぞれ捕食寄生者が脱出した.ハチ目では,両調査地で<i>Hyposoter</i> sp.(ヒメバチ科)が,それらに加えて三草山からはブランコサムライコマユバチ(コマユバチ科),ブランコクロカモドキバチと<i>Protapanteles</i> sp.(コマユバチ科)およびヒメバチ科の1種が,府大構内からはギンケハラボソコマユバチ(コマユバチ科),<i>Cotesia melanoscela</i>(コマユバチ科)が,それぞれ確認された.ハエ目では,府大構内でブランコヤドリバエとムラタヒゲナガハリバエ(ヤドリバエ科)が確認された.両調査地における優占種は,府大構内でブランコヤドリバエで全寄生者の約7割を占めたのに対して,三草山ではブランコクロカモドキバチであったが全寄生者の約2割にすぎなかった.各捕食寄生者による寄主の死亡個体数より算出した種多様度(1-λ)は,府大構内(0.55)より三草山(0.80)の方が高かった.

We investigated the parasitoid complex of gypsy moth populations in a coppice on Mt. Mikusa in northern Osaka and in urban greenery of the campus of Osaka Prefecture University (OPU) in southern Osaka in 1997. We collected 79 and 117 gypsy moth larvae on Mt. Mikusa and at the OPU, respectively, from May to July. The larvae were reared individually on fresh leaves of <i>Quercus acutissima</i> under a photoperiod of 14L-10D at 22°C. Seventeen (21%) and 36 (31%) larvae and pupae were killed by eight species of parasitoid for the Mt. Mikusa and OPU moth populations, respectively. The Hymenopteran parasitoid, <i>Hyposoter</i> sp. (Ichneumonidae) was obtained from both sites, while <i>Glyptapanteles liparidis, Protapanteles</i> sp. (Braconidae) and Ichneumonidae sp. were obtained only from Mt. Mikusa, and <i>Cotesia melanoscela, Meteorus pulchricornis</i> (Braconidae) were obtained only from OPU. The Dipteran parasitoids, <i>Exorista japonica</i> and <i>Bessa parallela</i> (Tachinidae) were obtained only from OPU. The percentage of <i>E. japonica</i> was 68% of the total parasitoids from OPU, while that of the dominant species, <i>A. lymantriae</i>, was only 23% on Mt. Mikusa. The species diversity (1-λ) of the parasitoid complex was higher on Mt. Mikusa (0.80) than at OPU (0.55).
